Corneal Characteristics In Children With Marfan Syndrome With Or Without Ectopia Lentis, Marisa O'Brien, Lawrence Tychsen

2020-Current year OA Pubs

IMPORTANCE: Myopia of Marfan syndrome (MFS) may be ascribed to crystalline lens subluxation, abnormal corneal curvature, and increased globe axial length. Few studies have reported these measures in MFS children who did or did not have ectopia lentis (EL).

OBJECTIVE: To measure eye findings longitudinally in MFS children with and without EL.

METHODS: A prospective, comparative case study was conducted on 24 MFS children (48 eyes). EL necessitated lensectomy and intraocular lens implantation surgery in 16/24 children (mean age 5.6 ± 2.8 years). The remaining 8/24 MFS children (mean age 11.2 ± 4.2 years) had no EL and were phakic. …

Mollusc And Crustacean Consumption In The First 1000 Days: A Scoping Review, Brietta M Oaks, Emmanuel A Gyimah, Eliza Kleban, Kathleen Ragsdale, Lora L Iannotti

2020-Current year OA Pubs

Mollusc and crustacean consumption in the first 1000 d may improve maternal and child health by providing essential nutrients. However, in some contexts, molluscs and crustaceans have been associated with allergies and environmental contamination, potentially leading to adverse health and development outcomes. It is unclear whether the health benefits of consuming molluscs and crustaceans, collectively classified as shellfish in nutrition, are outweighed by the potential risks to pregnant women and children. We conducted a scoping review (PROSPERO: CRD42022320454) in PubMed, Scopus and EBSCO Global Health of articles published between January 2000 and March 2022 that assessed shellfish consumption during pregnancy, …

Telemedicine In Nerve Surgery: An Effective Method To Determine Indications For Surgery, Noah S. Llaneras, Ruby L. Taylor, Jonah P. M. Orr, Rachel Alessio, Carolyn Carper, Brendan M. Patterson, Susan E. Mackinnon

2020-Current year OA Pubs

BACKGROUND: The COVID-19 pandemic accelerated the adoption of telemedicine for surgical consultations. Although patient satisfaction has been well documented, limited research exists regarding telemedicine's effectiveness in determining the ability to indicate for surgical care compared with in-office visits. We conducted a retrospective review comparing surgical decision-making via telemedicine versus in-person consultations, hypothesizing that in-office visits would be more effective in establishing a surgical plan than telemedicine.

METHODS: A retrospective review of the medical records of all new patients presenting to the senior author's nerve surgery clinic at a high-volume quaternary referral center between June 2020 and January 2023 was performed. …

We present the case of a 58-year-old gentleman who underwent TEVAR for aortic rupture during transcatheter aortic valve replacement, later presenting with TEVAR infection, endocarditis, and aortobronchial fistula who underwent TEVAR explantation, aortic valve replacement, and aortic reconstruction. The patient consented to publication of his operative course.

Genetically Encoded Biosensors Of Metabolic Function For The Study Of Neurodegeneration, A Review And Perspective, Minglei Zhao, Saman Behboudi Tanourlouee, Sean Mccracken, Philip R Williams

2020-Current year OA Pubs

Nervous system tissue is the most metabolically active in the body and neurons are the primary consumers of oxygen and metabolites in nervous tissue. Many processes support neuronal metabolism, and dysregulation of these processes or intrinsic neuronal metabolism is often tied to neurodegenerative diseases. While many techniques are available to query metabolic function and disease (e.g. Seahorse XF, histology, immunostaining), almost all of these approaches are destructive and few offer cellular resolution. However, genetically encoded biosensors can optically measure metabolic features in any tissue with optical access. Biosensors represent an approach to non-destructively monitor metabolic components and regulatory signaling repeatedly …

Innovations In Intestinal Organoid Technology Featuring An Open Apical Surface, Ye Chen, Yi Wang

2020-Current year OA Pubs

Since the development of the three-dimensional (3D) "mini-gut" culture system, adult stem cell-derived organoid technology has rapidly advanced, providing in vitro models that replicate key cellular, molecular, and physiological properties of multiple organs. The 3D intestinal organoid system has resolved many long-standing challenges associated with immortalized or cancer cell cultures, offering unparalleled capabilities for modeling gastrointestinal development and diseases. However, significant limitations remain, including restricted accessibility to the epithelial apical surface for studying host-microbe interactions, interruptions in modeling chronic gastrointestinal diseases due to frequent passaging and dissociation, and the absence of mechanical cues such as peristalsis and luminal flow, which …

Rna Interference In Protozoan Parasites And Its Application, Lon-Fye Lye, Deborah E Dobson, Stephen M Beverley, Min-Che Tung

2020-Current year OA Pubs

RNA interference (RNAi) is a biological process in which RNA molecules are involved in sequence-specific suppression of gene expression, via small RNA triggers derived from double-stranded RNA that can target specific genes; it is a natural process that plays a role in both the regulation of protein synthesis and in immunity. Discovery of RNAi by Fire and Mello in 1998 had a profound impact on unraveling novel aspects of eukaryotic biology. RNA interference (RNAi) has proven to be an immensely useful tool for studying gene function and validation of potential drug targets in almost all organisms. A great advance in …

Age-Related Mesenchymal Stromal Cell Senescence Is Associated With Progression From Mgus To Multiple Myeloma, Natalya Plakhova, Sheila A Stewart, Et Al.

2020-Current year OA Pubs

The risk of progression of monoclonal gammopathy of undetermined significance (MGUS) to multiple myeloma (MM) increases with advancing age, suggesting that progression may be influenced by age-related changes within the bone marrow (BM) microenvironment. We hypothesise that senescent mesenchymal stromal cells (MSCs), which accumulate in the BM with age, may contribute to MGUS progression to MM. Here, we show that, like BM MSCs from aged non-cancer controls, BM MSCs from both MM and MGUS patients exhibit a senescent phenotype characterised by enlarged, flattened morphology, increased β-galactosidase activity and CDKN2A expression, and decreased proliferation rate compared with BM MSCs from healthy …

White Matter Microstructure In School-Age Children With Down Syndrome, Dea Garic, Robert C Mckinstry, Natasha Marrus, Kelly N Botteron, Et Al.

2020-Current year OA Pubs

Down syndrome (DS) is the most common genetic cause of intellectual disability, but our understanding of white matter microstructure in children with DS remains limited. Previous studies have reported reductions in white matter integrity, but nearly all studies to date have been conducted in adults or relied solely on diffusion tensor imaging (DTI), which lacks the ability to disentangle underlying properties of white matter organization. This study examined white matter microstructural differences in 7- to 12-year-old children with DS (n = 23), autism (n = 27), and typical development (n = 50) using DTI as well as High Angular Resolution …

Measuring And Interpreting Individual Differences In Fetal, Infant, And Toddler Neurodevelopment, Halie A Olson, M Catalina Camacho, Natasha Marrus, Et Al.

2020-Current year OA Pubs

As scientists interested in fetal, infant, and toddler (FIT) neurodevelopment, our research questions often focus on how individual children differ in their neurodevelopment and the predictive value of those individual differences for long-term neural and behavioral outcomes. Measuring and interpreting individual differences in neurodevelopment can present challenges: Is there a "standard" way for the human brain to develop? How do the semantic, practical, or theoretical constraints that we place on studying "development" influence how we measure and interpret individual differences? While it is important to consider these questions across the lifespan, they are particularly relevant for conducting and interpreting research …

2020-Current year OA Pubs

Social cognition-the complex mental ability to perceive social stimuli and negotiate the social environment-has emerged as an important cognitive ability needed for social functioning, everyday functioning, and quality of life. Deficits in social cognition have been well documented in those with severe mental illness including schizophrenia and depression, those along the autism spectrum, and those with other brain disorders where such deficits profoundly impact everyday life. Moreover, subtle deficits in social cognition have been observed in other clinical populations, especially those that may have compromised non-social cognition (i.e., fluid intelligence such as memory). Among people living with HIV (PLHIV), 44% …

Insoluble tau aggregates within neurofibrillary tangles are a defining neuropathological feature of Alzheimer's disease (AD) and closely correlate with clinical symptoms. Although tau pathology can be assessed using tau positron emission tomography, a more accessible biomarker is needed for diagnosis, prognosis and tracking treatment effects. Here we present a new plasma tau species, the endogenously cleaved, microtubule-binding region containing residue 243 (eMTBR-tau243), which specifically reflects tau tangle pathology. Across the AD spectrum in three different cohorts (n = 108, 55 and 739), plasma eMTBR-tau243 levels were significantly elevated at the mild cognitive impairment stage and increased further in dementia. Plasma …

A Subset Of Cortical Areas Exhibit Adult-Like Functional Network Patterns In Early Childhood, Jiaxin Cindy Tu, Xintian Wang, Donna Dierker, Chloe M. Sobolewski, Evan M Gordon, Timothy O Laumann, Adam T Eggebrecht, Muriah D. Wheelock, Et Al.

2020-Current year OA Pubs

The human cerebral cortex contains groups of areas that support sensory, motor, cognitive, and affective functions, often categorized into functional networks. These networks show stronger internal and weaker external functional connectivity (FC), with FC profiles more similar within the same network. Previous studies have shown these networks develop from nascent forms before birth to their mature, adult-like structures in childhood. However, these analyses often rely on adult functional network definitions. This study assesses the potential misidentification of infant functional networks when using adult models and explores the consequences and possible solutions to this problem. Our findings suggest that although adult …

2020-Current year OA Pubs

People who use drugs (PWUD) are increasingly acquiring and transmitting hepatitis C virus (HCV) and being admitted to the hospital for often costly non-HCV-related conditions. Traditionally, treatment of HCV has been deferred to the outpatient setting. However, outpatient HCV follow-up can be an arduous process to navigate with resultant gaps in care, especially for PWUD with numerous complex psychosocial and medical comorbidities. Hospitalization presents a key opportunity to initiate treatment, and several institutions have piloted inpatient treatment models with intensive outreach. We conducted a narrative review of peer-reviewed literature (2014-2024) evaluating hospital-based HCV treatment models for PWUD; 6 studies from …

Assessing Neurocognitive Maturation In Early Adolescence Based On Baby And Adult Functional Brain Landscapes, Omid Kardan, Muriah D Wheelock, Jiaxin Cindy Tu, Et Al.

2020-Current year OA Pubs

Adolescence is a period of growth in cognitive performance and functioning. Recently, data-driven measures of brain-age gap, which can index cognitive decline in older populations, have been utilized in adolescent data with mixed findings. Instead of using a data-driven approach, here we assess the maturation status of the brain functional landscape in early adolescence by directly comparing an individual's resting-state functional connectivity (rsFC) to the canonical early-life and adulthood communities. Specifically, we hypothesized that the degree to which a youth's connectome is better captured by adult networks compared to infant/toddler networks is predictive of their cognitive development. To test this …
