Update on the Pathogenesis of Keloid Formation.

Keloids are abnormal skin growths occurring in a significant portion of the global population. Despite their pervasiveness, the underlying pathophysiology of this scarring process is yet to be fully understood. In this review article, we delve into the current literature on the pathophysiological mechanisms of keloids.

Lack of factor VIII detection in humans and dogs with an intron 22 inversion challenges hypothesis regarding inhibitor risk.

Background: Almost half of severe hemophilia A (HA) cases are caused by an intron 22 inversion (Int22Inv) mutation, which truncates the 26-exon F8 messenger RNA (mRNA) after exon 22. Another F8 transcript, F8, is initiated from within F8-intron-22. F8 mRNA consists of a short exon spliced to exons 23 to 26 and is expressed in multiple human cell types.

ATLAS: A positive, high-yield review of patient symptoms most significantly associated with melanoma recurrence.

Background: No standardized, evidence-based surveillance practices exist to guide and optimize recurrence detection in patients with cutaneous melanoma.

Objective: To determine the most high-yield positive review of systems for signaling recurrence in patients with cutaneous melanoma.

Methods: This retrospective cohort study assessed patients with a history of cutaneous melanoma and compared demographic and clinical characteristics, including a comprehensive review of systems, among those who experienced recurrence and those who did not.

Sustained generation of neurons destined for neocortex with oxidative metabolic upregulation upon filamin abrogation.

Neurons in the neocortex are generated during embryonic development. While the adult ventricular-subventricular zone (V-SVZ) contains cells with neural stem/progenitors' characteristics, it remains unclear whether it has the capacity of producing neocortical neurons. Here, we show that generating neurons with transcriptomic resemblance to upper layer neocortical neurons continues in the V-SVZ of mouse models of a human condition known as periventricular heterotopia by abrogating Flna and Flnb.

Child pedestrian safety training in virtual reality: How quickly do children achieve adult functioning and what individual differences impact learning efficiency?

Introduction: Pedestrian injuries represent a leading cause of child death globally. One prevention strategy is teaching children street-crossing skills. Virtual reality (VR) has emerged as a strategy to offer repeated street-crossing practice and overcome ethical barriers of training children in live traffic.

Teaching children pedestrian safety in virtual reality via smartphone: a noninferiority randomized clinical trial.

Objective: To evaluate whether child pedestrian safety training in a smartphone-based virtual reality (VR) environment is not inferior to training in a large, semi-immersive VR environment with demonstrated effectiveness.

Methods: Five hundred 7- and 8-year-old children participated; 479 were randomized to one of two conditions: Learning to cross streets in a smartphone-based VR or learning in a semi-immersive kiosk VR. The systems used identical virtual environments and scenarios.

CITIES: Clinical trials with intercurrent events simulator.

Although clinical trials are often designed with randomization and well-controlled protocols, complications will inevitably arise in the presence of intercurrent events (ICEs) such as treatment discontinuation. These can lead to missing outcome data and possibly confounding causal inference when the missingness is a function of a latent stratification of patients defined by intermediate outcomes. The pharmaceutical industry has been focused on developing new methods that can yield pertinent causal inferences in trials with ICEs.

Impact of social determinants of health on individuals living with generalized myasthenia gravis and implications for patient support programs.

Introduction: Social determinants of health (SDOH) are important contributors to health outcomes, and better understanding their impact on individuals diagnosed with rare, chronic diseases with high burden and unmet need is critical. Characterizing SDOH burden can help improve the design of patient support programs (PSPs), using targeted approaches to remove barriers to access.

Methods: This study used a mixed-methods strategy employing a quantitative survey, which was designed based on qualitative interviews, to understand the unmet needs and awareness/utilization of PSPs among individuals living with generalized myasthenia gravis (gMG) and experiencing SDOH barriers.

Evaluation of a New, Advanced Antioxidant Containing Topical Allyl Pyrroloquinoline Quinone: Analysis of Antioxidant Properties and Visible Effects in Subjects with Facial Photodamage.

Objectives: Evaluate the effects of a new antioxidant containing topical allyl pyrroloquinoline quinone (TAP) on expression of key markers and assess the efficacy and tolerability in subjects with photodamaged skin.

Methods: Donor skin tissue was irradiated prior to and following application of study products (TAP; a leading antioxidant cream [L-VC]). Expression of markers related to epidermal homeostasis and oxidative stress were assessed at 48 hours and compared to untreated, irradiated control (n=3 each).

Advanced Practitioner-Led Shared Visits: A Novel Approach to Cancer Survivorship.

Background: The continued increase in the number of cancer survivors is encouraging and credited to better prevention, screening, and treatment. Cancer care authorities call for survivorship follow-up focusing on surveillance, health behaviors, and lingering effects of treatment. Despite the recommendations, cancer centers struggle to provide cost-effective, time efficient, comprehensive programming to address this call.

Evaluating Current Tuition Trends in Radiography Programs.

Purpose: To identify current tuition trends among types of radiography programs; compare tuition rates; and provide prospective students, educators, and professionals with a comprehensive cost analysis for postsecondary education planning, recruitment, and retention.

Methods: Radiography program tuition data were collected from the Joint Review Committee on Education in Radiologic Technology (JRCERT) website. National tuition rates were obtained from the National Center for Education Statistics website.

Live-Cell Imaging of Dynein-Mediated Cargo Transport in Aspergillus nidulans.

Filamentous fungi have been used for studying long-distance transport of cargoes driven by cytoplasmic dynein. Aspergillus nidulans is a well-established genetic model organism used for studying dynein function and regulation in vivo. Here, we describe how we grow A.

Diverse Enterococcus faecalis strains show heterogeneity in biofilm properties.

Biofilm formation is important for Enterococcus faecalis to cause healthcare-associated infections. It is unclear how E. faecalis biofilms vary in parameters such as development and composition.

Improving Body Skin Quality: Evidence-Based Development of Topical Treatment and Survey of Current Options.

The growing interest in improving the quality of body (as distinct from facial) skin may be in part attributable to the expanding use of noninvasive body contouring procedures. In this review, we describe a new framework characterizing the factors that define skin quality (including visual, textural, and biomechanical attributes) that provides a foundation for improved assessment of skin quality and its response to treatment. We then highlight critical biological pathways responsible for body skin restoration and maintenance that have been identified during the development of restorative topical products.

Nde1 is required for heterochromatin compaction and stability in neocortical neurons.

The gene encodes a scaffold protein essential for brain development. Although biallelic loss of function (LOF) causes microcephaly with profound mental retardation, missense mutations and copy number variations are associated with multiple neuropsychiatric disorders. However, the etiology of the diverse phenotypes resulting from aberrations remains elusive.

CARD19 Interacts with Mitochondrial Contact Site and Cristae Organizing System Constituent Proteins and Regulates Cristae Morphology.

CARD19 is a mitochondrial protein of unknown function. While CARD19 was originally reported to regulate TCR-dependent NF-κB activation via interaction with BCL10, this function is not recapitulated ex vivo in primary murine CD8 T cells. Here, we employ a combination of SIM, TEM, and confocal microscopy, along with proteinase K protection assays and proteomics approaches, to identify interacting partners of CARD19 in macrophages.

Tourniquet-induced lower limb ischemia/reperfusion reduces mitochondrial function by decreasing mitochondrial biogenesis in acute kidney injury in mice.

The mechanisms by which lower limb ischemia/reperfusion induces acute kidney injury (AKI) remain largely uncharacterized. We hypothesized that tourniquet-induced lower limb ischemia/reperfusion (TILLIR) would inhibit mitochondrial function in the renal cortex. We used a murine model to show that TILLIR of the high thigh regions inflicted time-dependent AKI as determined by renal function and histology.

Multi-attribute Raman spectroscopy (MARS) for monitoring product quality attributes in formulated monoclonal antibody therapeutics.

Rapid release of biopharmaceutical products enables a more efficient drug manufacturing process. Multi-attribute methods that target several product quality attributes (PQAs) at one time are an essential pillar of the rapid-release strategy. The novel, high-throughput, and nondestructive multi-attribute Raman spectroscopy (MARS) method combines Raman spectroscopy, design of experiments, and multivariate data analysis (MVDA).

Effects of easing shelter-in-place restrictions and the lingering COVID-19 pandemic on orthopaedic trauma at a community level 2 trauma center.

Objectives: Evaluate the effect of easing "shelter-in-place" restrictions and coronavirus-2019 (COVID-19) cases on orthopaedic trauma encounters (OTEs) at a community level II trauma center.

Methods: A retrospective analysis was conducted of OTEs from March-June of 2016 to 2020. Injuries were classified by high or low severity.

Genetic inactivation of SARM1 axon degeneration pathway improves outcome trajectory after experimental traumatic brain injury based on pathological, radiological, and functional measures.

Traumatic brain injury (TBI) causes chronic symptoms and increased risk of neurodegeneration. Axons in white matter tracts, such as the corpus callosum (CC), are critical components of neural circuits and particularly vulnerable to TBI. Treatments are needed to protect axons from traumatic injury and mitigate post-traumatic neurodegeneration.

Regulation of neonatal IgA production by the maternal microbiota.

Infants are prone to enteric infections due to an underdeveloped immune system. The maternal microbiota, through shaping the neonatal microbiota, helps establish a strong immune system in infants. We and others have observed the phenomenon of enhanced early neonatal immunoglobulin A (IgA) production in preweaning immunocompetent mice nursed by immunodeficient dams.
