Modified Distalization Shoulder Angle and Lateralization Shoulder Angle show weakly correlation with clinical outcomes following reverse shoulder arthroplasty.

Introduction: The focus in reverse shoulder arthroplasty (RSA) has been on the lateralization and distalization of prosthesis positioning, influenced by implant design and surgical technique. There's no consensus on the optimal amount of lateralization and distalization or the best radiographic parameters for evaluating placement. This study examines the correlation and the predictive value between previously described modified distalization shoulder angle (DSA) and lateralization shoulder angle (LSA) with postoperative outcomes, which aim to differentiate the contributions of the humeral and glenoid components in the global distalization and lateralization of the RSA.

Neurotransmitters and neural hormone-based probes for quadruplex DNA sequences associated with neurodegenerative diseases.

The potential of neurotransmitters and neural hormones as possible G-quadruplex DNA binders was analyzed using fluorescence spectroscopy, surface-enhanced Raman spectroscopy (SERS), DNA melting analysis, and molecular docking. G-quadruplex sequences, (GGC) and GC, with roles in Fragile X syndrome and amyotrophic lateral sclerosis (ALS), respectively, were selected, and their interactions with melatonin, serotonin, and gamma-aminobutyric acid (GABA), were studied. Both melatonin and serotonin demonstrated strong interactions with the DNA sequences with hydrogen bonding being the primary mode of interaction, with some non-intercalative interactions involving the π systems.

Rhodium nanospheres for ultraviolet and visible plasmonics.

The development and understanding of alternative plasmonic materials are crucial steps for leveraging new plasmonic technologies. Although gold and silver nanostructures have been intensively studied, the promising plasmonic, chemical and physical attributes of rhodium remain poorly investigated. Here, we report the synthesis and plasmonic response of spherical Rh nanoparticles (NPs) with sizes in the 20-40 nm range.

Perspectives on the sustained engagement with digital health tools: protocol for a qualitative interview study among people living with Inflammatory Bowel Disease or irritable bowel syndrome.

Introduction: Digital health tools can be beneficial in the care of patients with chronic conditions and have the potential for widespread impact as readily scalable and cost-effective health interventions. However, benefits are often contingent on users sustaining their engagement with these tools over time. Sustained engagement with digital health tools can be challenging, and high rates of attrition from digital interventions are common.

Clinical parameters of death and heart failure hospitalization in biventricular systolic dysfunction assessed via cardiac magnetic resonance.

Aims: While factors associated with adverse events are well elucidated in setting of isolated left ventricular dysfunction, clinical and imaging-based prognosticators of adverse outcomes are lacking in context of biventricular dysfunction. The purpose of this study was to establish role of clinical variables in prognosis of biventricular heart failure (HF), as assessed by cardiac magnetic resonance imaging.

Methods: Study cohort consisted of 840 patients enrolled in DERIVATE registry with coexisting CMR-derived right ventricular (RV) and left ventricular (LV) dysfunction, as defined by RV and LV ejection fractions ≤45 % and ≤ 50 %, respectively.
