Long-term clinical outcomes for patients with uncrossable patent foramen ovale.

Introduction: Patent foramen ovale (PFO) closure is performed in selected patients with cryptogenic stroke to prevent recurrence. The prognosis of patients with uncrossable PFO after failed guidewire or catheter passage during the procedure remains unknown. We compared the long-term prognosis between uncrossable PFO and successful PFO closure in patients with high-grade PFO shunts.

Safety and Efficacy of Post-Dilation in Percutaneous Coronary Intervention Using Polymer-Free Ultrathin Strut Sirolimus-Probucol Coated Drug-Eluting Stents.

: Polymer-free ultrathin strut sirolimus- and probucol-eluting stents (PF-SES) are recognized as safe and effective in diverse patient populations, although the implications of post-dilation during stent implantation remain underexamined. : In this study, patients implanted with PF-SES at Gachon University Gil Medical Center between December 2014 and February 2018 were evaluated. Major adverse cardiovascular events (MACE), encompassing nonfatal myocardial infarction (MI), nonfatal stroke, and cardiovascular death were identified as primary outcomes, with secondary outcomes including target vessel revascularization (TVR), target lesion revascularization (TLR), and in-stent restenosis (ISR).

Intervertebral disc organ-on-a-chip: an innovative model to study monocyte extravasation during nucleus pulposus degeneration.

Degenerative cascades of the intervertebral disc (IVD) are characterized by the presence of immune cells like monocytes, macrophages, and leukocytes, which contribute to inflammation. Previous studies on monocyte chemotaxis in the presence of chemical or mechanical stimulation were unable to establish the effects of endogenous stimulating factors from resident IVD cells, or fully understand macrophage and monocyte differentiation pathways in IVD degeneration. Our study simulates monocyte extravasation using a fabricated microfluidic chemotaxis IVD organ-on-a-chip (IVD organ chip), which models the geometry of IVD, chemoattractant diffusion, and infiltration of immune cells.

In situ droplet-based on-tissue chemical derivatization for lipid isomer characterization using LESA.

In this work, we present an in situ droplet-based derivatization method for fast tissue lipid profiling at multiple isomer levels. On-tissue derivatization for isomer characterization was achieved in a droplet delivered by the TriVersa NanoMate LESA pipette. The derivatized lipids were then extracted and analyzed by the automated chip-based liquid extraction surface analysis (LESA) mass spectrometry (MS) followed by tandem MS to produce diagnostic fragment ions to reveal the lipid isomer structures.

An Active Inference Account of Touch and Verbal Communication in Therapy.

Osteopathic Care as (En)active Inference: A Theoretical Framework for Developing an Integrative Hypothesis in Osteopathy.

Osteopathy is a person-centred healthcare discipline that emphasizes the body's structure-function interrelationship-and its self-regulatory mechanisms-to inform a whole-person approach to health and wellbeing. This paper aims to provide a theoretical framework for developing an integrative hypothesis in osteopathy, which is based on the enactivist and active inference accounts. We propose that osteopathic care can be reconceptualised under (En)active inference as a unifying framework.

The effects of positive or negative self-talk on the alteration of brain functional connectivity by performing cognitive tasks.

Self-talk can improve cognitive performance, but the underlying mechanism of such improvement has not been investigated. This study aimed to elucidate the effects of self-talks on functional connectivity associated with cognitive performance. We used the short form of Progressive Matrices Test (sRPM) to measure differences in performance improvements between self-respect and self-criticism.

Differences in basic psychological needs-related resting-state functional connectivity between individuals with high and low life satisfaction.

Basic psychological needs including autonomy, competence, and relatedness can be affected by the level of life satisfaction. The current research aimed to elucidate differences in the association of these needs and functional connectivity of reward processing and emotion regulation between individuals with high and low life satisfaction. A total of 83 young adults were divided into the high life satisfaction (HLS) and low life satisfaction (LLS) groups and were scanned for 5-min resting-state fMRI.

In vitro model of distinct catabolic and inflammatory response patterns of endothelial cells to intervertebral disc cell degeneration.

To evaluate dominant cell-to-cell paracrine interactions, including those of human annulus fibrosus (AF), nucleus pulposus (NP), and endothelial cells (ECs), in the production of inflammatory mediators and catabolic enzymes, ECs was cultured in soluble factors derived from AF or NP cells (AFCM or NPCM, respectively) and vice versa. We analysed IL-6 and -8, vascular endothelial growth factor (VEGF), matrix metalloproteinase (MMP)-1 and -3, nerve growth factor (NGF)-β, and brain-derived neurotrophic factors (BDNFs) with qRT-PCR and ELISA. We implement a microfluidic platform to analyse migration properties of AF and NP cells and ECs in 3D cultures.

Effects of photobiomodulation on annulus fibrosus cells derived from degenerative disc disease patients exposed to microvascular endothelial cells conditioned medium.

Intervertebral disc (IVD) degeneration with chronic low back pain is associated with neo-vascularisation into the deeper IVD regions. During this process, endothelial cells (ECs), which are primarily responsible for angiogenesis, interact with the adjacent annulus fibrosus (AF) cells, which are the first line of defence against the invasion of vascular structures into deeper IVD regions. However, the accumulation of inflammatory and catabolic enzymes that results from this interaction promotes matrix degradation and an inflammatory response.

Differences in the modulation of functional connectivity by self-talk tasks between people with low and high life satisfaction.

Self-respect is a practical way to promote life satisfaction through gratifying basic psychological needs, whereas self-criticism is associated with life dissatisfaction. The goal of the present study was to investigate the effect of two positive and negative self-talks on the functional connectome with respect to life satisfaction and its relationships with basic psychological needs. Forty-eight individuals with low life satisfaction (LLS, n ​= ​24) and with high life satisfaction (HLS, n ​= ​24) were scanned using functional magnetic resonance imaging at a baseline state and during and after self-respect or self-criticism tasks.

Feasibility of a virtual reality-based interactive feedback program for modifying dysfunctional communication: a preliminary study.

The present preliminary study addressed the feasibility of a virtual reality (VR)-based interactive feedback program for the modification of dysfunctional communication.

Methods: Thirty-seven healthy young males completed psychological assessments associated with functional communication and participated in the VR-based program, consisting of the three tasks of 'exploring the communication style,' 'practicing functional communication,' and 'expressing empathy.

Electrical impulse effects on degenerative human annulus fibrosus model to reduce disc pain using micro-electrical impulse-on-a-chip.

Electrical stimulation of cells and tissues for therapeutic benefit is a well-established method. Although animal studies can emulate the complexity of an organism's physiology, lab-on-a-chip platforms provide a suitable primary model for follow-up animal studies. Thus, inexpensive and easy-to-use platforms for in vitro human cell studies are required.
