Incidence of Ophthalmological Complications in NF-1 Patients Treated with MEK Inhibitors.

MEK inhibitors (MEKi) represent innovative and promising treatments for managing manifestations of neurofibromatosis type 1 (NF1). To mitigate potential ophthalmic side effects, such as MEKi-associated retinopathy (MEKAR), patients undergoing MEKi therapy routinely receive ophthalmology evaluations. Our study aims to assess the necessity of this regular screening within a predominantly pediatric NF1 population by examining the occurrence of ocular adverse events (OAE).

Comprehensive Analysis of the Spatial Distribution of Gadolinium, Iron, Manganese, and Phosphorus in the Brain of Healthy Rats After High-Dose Administrations of Gadodiamide and Gadobutrol.

Objectives: After the administration of gadolinium-based contrast agents (GBCAs), residual gadolinium (Gd) has been detected in a few distinct morphological structures of the central nervous system (CNS). However, a systematic, comprehensive, and quantitative analysis of the spatial Gd distribution in the entire brain is not yet available. The first aim of this study is to provide this analysis in healthy rats after administration of high GBCA doses.

Dynamic parametric MRI and deep learning: Unveiling renal pathophysiology through accurate kidney size quantification.

Renal pathologies often manifest as alterations in kidney size, providing a valuable avenue for employing dynamic parametric MRI as a means to derive kidney size measurements for the diagnosis, treatment, and monitoring of renal disease. Furthermore, this approach holds significant potential in supporting MRI data-driven preclinical investigations into the intricate mechanisms underlying renal pathophysiology. The integration of deep learning algorithms is crucial in achieving rapid and precise segmentation of the kidney from temporally resolved parametric MRI, facilitating the use of kidney size as a meaningful (pre)clinical biomarker for renal disease.

Early protective effect of a ("pan") coronavirus vaccine (PanCoVac) in Roborovski dwarf hamsters after single-low dose intranasal administration.

Introduction: The coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has highlighted the danger posed by human coronaviruses. Rapid emergence of immunoevasive variants and waning antiviral immunity decrease the effect of the currently available vaccines, which aim at induction of neutralizing antibodies. In contrast, T cells are marginally affected by antigen evolution although they represent the major mediators of virus control and vaccine protection against virus-induced disease.

Supporting Parkinson's disease medication safety for nurses in the acute care setting through an educational intervention study.

Introduction: Patient medication safety in the acute care setting is a foundational action provided by nurses and healthcare providers for safe patient care. Hospitalization of patients with Parkinson's disease (PD) can be dangerous due to the unique and variable medication regimen required. Patients with PD often have their medication administered inappropriately in the acute care setting (e.

Continuous diffusion spectrum computation for diffusion-weighted magnetic resonance imaging of the kidney tubule system.

Background: The use of rigid multi-exponential models (with predefined numbers of components) is common practice for diffusion-weighted MRI (DWI) analysis of the kidney. This approach may not accurately reflect renal microstructure, as the data are forced to conform to the assumptions of simplified models. This work examines the feasibility of less constrained, data-driven non-negative least squares (NNLS) continuum modelling for DWI of the kidney tubule system in simulations that include emulations of pathophysiological conditions.

Reliable kidney size determination by magnetic resonance imaging in pathophysiological settings.

Aim: Kidney diseases constitute a major health challenge, which requires noninvasive imaging to complement conventional approaches to diagnosis and monitoring. Several renal pathologies are associated with changes in kidney size, offering an opportunity for magnetic resonance imaging (MRI) biomarkers of disease. This work uses dynamic MRI and an automated bean-shaped model (ABSM) for longitudinal quantification of pathophysiologically relevant changes in kidney size.

Schwannoma with Psammoma Body.

We present a case of a 59-year-old male veteran with a chronic history of right foot soft-tissue mass that was causing pain in his shoes, but not functional or neurologic symptoms. Excision of the mass and pathologic evaluation resulted in multidisciplinary involvement and evaluation. In this example, the mass was found to be either an unusual schwannoma that happens to be psammoma body-rich or an unusual psammomatous melanocytic schwannoma that deviates from conventional examples, as a diagnostic consensus was unable to be reached.

Measuring the predictability of life outcomes with a scientific mass collaboration.

How predictable are life trajectories? We investigated this question with a scientific mass collaboration using the common task method; 160 teams built predictive models for six life outcomes using data from the Fragile Families and Child Wellbeing Study, a high-quality birth cohort study. Despite using a rich dataset and applying machine-learning methods optimized for prediction, the best predictions were not very accurate and were only slightly better than those from a simple benchmark model. Within each outcome, prediction error was strongly associated with the family being predicted and weakly associated with the technique used to generate the prediction.

Evaluation of multiplex ligation dependent probe amplification (MLPA) for identification of acute lymphoblastic leukemia with an intrachromosomal amplification of chromosome 21 (iAMP21) in a Brazilian population.

Background: An intrachromosomal amplification of chromosome 21 (iAMP21) defines a unique subgroup of B-cell precursor acute lymphoblastic leukemia (BCP-ALL). The finding of three or more extra copies of the RUNX1 gene by fluorescence in situ hybridization (FISH) is internationally used to define an iAMP21. Genomic profiling of chromosome 21 has been suggested for assisting diagnostic case identification.

Adolescent vulnerability to cardiovascular consequences of chronic social stress: Immediate and long-term effects of social isolation during adolescence.

It has been demonstrated that disruption of social bonds and perceived isolation (loneliness) are associated with an increased risk of cardiovascular morbidity and mortality. Adolescence is proposed as a period of vulnerability to stress. Nevertheless, the impact of chronic social stress during this ontogenic period in cardiovascular function is poorly understood.

IL-10, IL-4, and STAT6 promote an M2 milieu required for termination of P0(106-125)-induced murine experimental autoimmune neuritis.

The role of the type 2 helper T cell (Th2)-polarizing cytokines IL-4 and IL-10 has not yet been studied in P0106-125-induced murine experimental autoimmune neuritis (EAN). We, therefore, addressed the functional relevance of these cytokines and signaling via the IL-4-associated transcription factor STAT6. The clinical course of P0106-125-induced EAN in mice deficient for IL-10(0/0), IL-4(0/0), or STAT6(0/0) was significantly aggravated compared with that of wild-type control mice.

Near-infrared spectroscopy to detect absence of cerebrovascular autoregulation in preterm infants.

Objective: Our aim was to explore clinical parameters that might predict the absence of cerebrovascular autoregulation (CAR) assessed by a negative relationship between mean arterial blood pressure (MABP) and fractional tissue oxygen extraction (FTOE) as measured by near-infared spectroscopy (NIRS) in preterm infants.

Methods: We included preterm infants (gestational age (GA) <32 weeks). Within 72 h after birth, we recorded the infants' NIRS parameters and MABP for a 24-h period.

Nocturia, nocturnal activity, and nondipping.

Patients with chronic kidney disease have less than expected decline in blood pressure during sleep (nondipping) and commonly experience the vexing symptom of nocturia. To better understand the relationship among nocturia, nighttime physical activity, and nondipping, we studied 98 patients with chronic kidney disease on 2 occasions, 1 month apart, with 24-hour ambulatory blood pressure monitoring and simultaneous activity monitoring with wrist actigraphy. Patients with nocturia had greater actigraphically recorded nighttime physical activity compared to those with no nocturia.
