V3+ extends the V3 framework to ensure user-centricity and scalability of sensor-based digital health technologies.

We propose the addition of usability validation to the extended V3 framework, now "V3+", and describe a pragmatic approach to ensuring that sensor-based digital health technologies can be used optimally at scale by diverse users. Alongside the original V3 components (verification; analytical validation; clinical validation), usability validation will ensure user-centricity of digital measurement tools, paving the way for more inclusive, reliable, and trustworthy digital measures within clinical research and clinical care.

Influence of Added Cellulose Nanocrystals on the Rheology of Polymers.

The interactions between cellulose nanocrystals and six different polymers (three anionic, two non-ionic, and one cationic) were investigated using rheological measurements of aqueous solutions of nanocrystals and polymers. The experimental viscosity data could be described adequately by a power-law model. The variations in power-law parameters (consistency index and flow behavior index) with concentrations of nanocrystals and polymers were determined for different combinations of nanocrystals and polymers.

The First Case Report of a Homozygous Consensus Acceptor Splice Variant in the NUP214 Gene Associated With Fetal Hydrops and Arthrogryposis Multiplex.

The gene encodes a nuclear pore complex protein (nucleoporin, 214 kilodaltons) which plays a critical role in messenger RNA export to the cytoplasm and import of substrates from the cytoplasm. Biallelic mutations in the gene have been associated with susceptibility to acute infection-induced encephalopathy type 9 (ILAE9) (Online Mendelian Inheritance in Man (OMIM), 114350), an autosomal recessive disorder. Herein, we describe for the first time, a fetus with hydrops and arthrogryposis multiplex with a homozygous novel consensus splice site variant in the NUP214 gene, chr9:g.

One step 4× and 12× 3D-ExM enables robust super-resolution microscopy of nanoscale cellular structures.

Super-resolution microscopy has become an indispensable tool across diverse research fields, offering unprecedented insights into biological architectures with nanometer scale resolution. Compared with traditional nanometer-scale imaging methods such as electron microscopy, super-resolution microscopy offers several advantages, including the simultaneous labeling of multiple target biomolecules with high specificity and simpler sample preparation, making it accessible to most researchers. In this study, we introduce two optimized methods of super-resolution imaging: 4-fold and 12-fold 3D-isotropic and preserved Expansion Microscopy (4× and 12× 3D-ExM).

Extracellular vesicles, including large translating vesicles called midbody remnants, are released during the cell cycle.

Extracellular vesicles (EVs) play crucial roles in cell-cell communication, but the biogenesis of large EVs has remained elusive. Here, we show that the biogenesis of large EVs (>800 nm-2 µm) occurs predominantly through the completion of successful cytokinesis, and the majority of large EVs are midbody remnants (MBRs) with translation activity, and the unique marker MKLP1. Blocking the cell cycle or cytokinesis, genetically or chemically, significantly decreases MBRs and large (800 nm-2 µm), medium (500-800 nm), and small (<300 nm) EVs, suggesting that proliferative cells can also generate all sizes of EVs.

National trends and outcomes of hospital presentation mode for endovascular stroke treatment in the U.S.

Background: The optimal triage strategy for patients suspected of acute ischemic stroke due to large vessel occlusion (LVO) remains debated. We explored trends in presentation mode and their outcomes for mechanical thrombectomy (MT) hospitalizations based on the National Inpatient Sample (NIS) database.

Methods: We retrospectively explored the NIS database from 2016 to 2020 for stroke hospitalizations with MT.

National trends in the endovascular and surgical treatment of idiopathic intracranial hypertension.

Background: The pattern of surgical treatments for Idiopathic Intracranial Hypertension (IIH) in the United States is not well-studied, specifically the trend of utilizing endovascular venous stenting (EVS) as an emerging technique.

Methods: In this cross-sectional study, we aimed to explore the national trend of utilizing different procedures for the treatment of IIH including EVS, Optic Nerve Sheath Fenestration (ONSF), and CSF Shunting, with a focus on novel endovascular procedures. Moreover, we explored rates of 90-day readmission and length of hospital stay following different procedures, besides the effects of sociodemographic and clinical parameters on procedure choice.

Plateauing atrial fibrillation burden in acute ischemic stroke admissions in the United States from 2010 to 2020.

Background: Utilization of oral anticoagulants for acute ischemic stroke (AIS) prevention in patients with atrial fibrillation (AF) increased in the United States over the last decade. Whether this increase has been accompanied by any change in AF prevalence in AIS at the population level remains unknown. The aim of this study is to evaluate trends in AF prevalence in AIS hospitalizations in various age, sex, and racial subgroups over the last decade.

Remdesivir, dexamethasone and angiotensin-converting enzyme inhibitors use and mortality outcomes in COVID-19 patients with concomitant troponin elevation.

Background: There are indications that viral myocarditis, demand ischemia, and renin-angiotensin-aldosterone system pathway activation play essential roles in troponin elevation in coronavirus disease 2019 (COVID-19) patients. Antiviral medications and steroids are used to treat viral myocarditis, but their effect in patients with elevated troponin, possibly from myocarditis, has not been studied.

Aim: To evaluate the effect of dexamethasone, remdesivir, and angiotensin-converting enzyme (ACE) inhibitors (ACEI) on mortality in COVID-19 patients with elevated troponin.

3D printed elastomeric biomaterial mitigates compaction during in vitro vasculogenesis.

A key parameter for the success of most cellular implants is the formation of a complete and comprehensive intra-implant vessel network. Pre-vascularization, the generation of vessel structures in vitro prior to transplantation, provides accelerated implant perfusion via anastomosis, but scalability and ease of integration hinder clinical translation. For fibrin-based vasculogenesis approaches, the remodeling and degradation of the fragile, hydrogel matrix during the formation of vessel-like structures results in rapid, cell-mediated construct compaction leading to dense, capillary-like structures with ineffective network coverage.

A protocol for isolating and imaging large extracellular vesicles or midbody remnants from mammalian cell culture.

Traditionally, midbody remnants (MBRs) are isolated from cell culture medium using ultracentrifugation, which is expensive and time consuming. Here, we present a protocol for isolating MBRs or large extracellular vesicles (EVs) from mammalian cell culture using either 1.5% polyethylene glycol 6000 (PEG6000) or PEG5000-coated gold nanoparticles.

Aneurysmal Subarachnoid Hemorrhage and Cardiac Related Fatality: Who Dies and Why?

Medical complications are a notable source of in-hospital death following aneurysmal subarachnoid hemorrhage (aSAH). However, there is a paucity of literature examining medical complications on a national scale. This study uses a national dataset to analyze the incidence rates, case fatality rates, and risk factors for in-hospital complications and mortality following aSAH.

Rigorous and rapid evidence assessment in digital health with the evidence DEFINED framework.

Dozens of frameworks have been proposed to assess evidence for digital health interventions (DHIs), but existing frameworks may not facilitate DHI evidence reviews that meet the needs of stakeholder organizations including payers, health systems, trade organizations, and others. These organizations may benefit from a DHI assessment framework that is both rigorous and rapid. Here we propose a framework to assess Evidence in Digital health for EFfectiveness of INterventions with Evaluative Depth (Evidence DEFINED).
