Therapy response monitoring in blood plasma from esophageal adenocarcinoma patients using cell-free DNA methylation profiling.

Esophageal adenocarcinoma (EAC) is an aggressive cancer characterized by a high risk of relapse post-surgery. Current follow-up methods (serum carcinoembryonic antigen detection and PET-CT) lack sensitivity and reliability, necessitating a novel approach. Analyzing cell-free DNA (cfDNA) from blood plasma emerges as a promising avenue.

Use of Digital Health and Digital Therapeutics to Treat SUD in Criminal Justice Settings: a Review.

Purpose Of Review: The purpose of this review is to investigate the use of digital health technologies and/or digital therapeutics (DTx) products in the treatment of substance use disorders (SUDs) in the general population and among criminal justice-involved individuals.

Recent Findings: Despite an expanding evidence base, only three SUD DTxs have received federal regulatory approval. Across studies, DTx products have proven successful in engaging patients in SUD treatment and reducing healthcare costs and resource utilizations.

Is Magnetic Resonance Imaging Overused Among Patients Undergoing Total Knee Arthroplasty?

Introduction: With increasing healthcare costs, it is important to quantify the number of total knee arthroplasty (TKA) patients who have MRIs that are not considered clinically necessary. The purpose of this study was to determine the number of unnecessary preconsultation MRIs done among TKA patients at our institution.

Methods: Eight hundred and sixty-nine patients who underwent a primary TKA were identified.

Temperature and fertility: Evidence from Spain.

In this paper, we combine administrative data for Spain from 2010 to 2018 with meteorological data, to identify the effect of daily mean temperature on fertility. We demonstrate for Spain that hot days (≥25°C) decrease the total fertility rate nine months after exposure. Moreover, we do not observe any substantial heterogeneities in the effect of heat by mother's age, mother's educational attainment, sex of the newborn, climatic area, or air conditioning penetration.

Autism-associated CHD8 controls reactive gliosis and neuroinflammation via remodeling chromatin in astrocytes.

Reactive changes of glial cells during neuroinflammation impact brain disorders and disease progression. Elucidating the mechanisms that control reactive gliosis may help us to understand brain pathophysiology and improve outcomes. Here, we report that adult ablation of autism spectrum disorder (ASD)-associated CHD8 in astrocytes attenuates reactive gliosis via remodeling chromatin accessibility, changing gene expression.

Osmotic gradient ektacytometry - a novel diagnostic approach for neuroacanthocytosis syndromes.

Introduction: The unique red blood cell (RBC) properties that characterize the rare neuroacanthocytosis syndromes (NAS) have prompted the exploration of osmotic gradient ektacytometry (Osmoscan) as a diagnostic tool for these disorders. In this exploratory study, we assessed if Osmoscans can discriminate NAS from other neurodegenerative diseases.

Methods: A comprehensive assessment was conducted using Osmoscan on a diverse group of patients, including healthy controls ( = 9), neuroacanthocytosis syndrome patients ( = 6, 2 VPS13A and 4 XK disease), Parkinson's disease patients ( = 6), Huntington's disease patients (n = 5), and amyotrophic lateral sclerosis patients ( = 4).

Host control of the microbiome: Mechanisms, evolution, and disease.

Many species, including humans, host communities of symbiotic microbes. There is a vast literature on the ways these microbiomes affect hosts, but here we argue for an increased focus on how hosts affect their microbiomes. Hosts exert control over their symbionts through diverse mechanisms, including immunity, barrier function, physiological homeostasis, and transit.

isolateR: an R package for generating microbial libraries from Sanger sequencing data.

Motivation: Sanger sequencing of taxonomic marker genes (e.g. 16S/18S/ITS/rpoB/cpn60) represents the leading method for identifying a wide range of microorganisms including bacteria, archaea, and fungi.

Acute myeloid leukemia stem cell signature gene EMP1 is not an eligible therapeutic target.

Background: Relapse in pediatric acute myeloid leukemia (pedAML) patients is known to be associated with residual leukemic stem cells (LSC). We have previously shown that epithelial membrane protein 1 (EMP1) is significantly overexpressed in LSC compared to hematological stem cell fractions. EMP1 was also documented as part of the 17-gene stemness score and a 6-membrane protein gene score, both correlating high EMP1 expression with worse overall survival.

Short developmental milestone risk assessment tool to identify Duchenne muscular dystrophy in primary care.

Background: In patients without a family history, Duchenne muscular dystrophy (DMD) is typically diagnosed at around 4-5 years of age. It is important to diagnose DMD during infancy or toddler stage in order to have timely access to treatment, opportunities for reproductive options, prevention of potential fatal reactions to inhaled anesthetics, awareness of a child's abilities needed for good parenting, and opportunities for enrolment in clinical trials.

Method: We aimed to develop a short risk assessment tool based on developmental milestones that may contribute to the early detection of boys with DMD in primary care.

Assessing phage-host population dynamics by reintroducing virulent viruses to synthetic microbiomes.

Microbiomes feature complex interactions between diverse bacteria and bacteriophages. Synthetic microbiomes offer a powerful way to study these interactions; however, a major challenge is obtaining a representative bacteriophage population during the bacterial isolation process. We demonstrate that colony isolation reliably excludes virulent viruses from sample sources with low virion-to-bacteria ratios such as feces, creating "virulent virus-free" controls.

Ray-tracing model of a perfect lens compliant with Fermat's principle: the Cardinal Lens.

When using ray tracing for optical system design, it is often the case that the designer would like to implement simplified versions of one or more compound lens groups. This could be the case during initial layout when idealized versions of such compound lenses are needed or, perhaps alternatively, to mimic a well-corrected commercially available lens for which the prescription details are unavailable. One option is to use a paraxial thin lens as a proxy for the actual lens group, but doing so will yield a layout that is not consistent with Fermat's principle or the Abbe sine condition.

A novel composition of endogenous metabolic modulators improves red blood cell properties in sickle cell disease.

The most common forms of sickle cell disease (SCD) are sickle cell anemia (SCA; HbSS) and HbSC disease. In both, especially the more dense, dehydrated and adherent red blood cells (RBCs) with reduced deformability are prone to hemolysis and sickling, and thereby vaso-occlusion. Based on plasma amino acid profiling in SCD, a composition of 10 amino acids and derivatives (RCitNacQCarLKHVS; Axcella Therapeutics, USA), referred to as endogenous metabolic modulators (EMMs), was designed to target RBC metabolism.

'On Table' Versus 'Off Table' Direct Anterior Approach Total Hip Arthroplasty: Is There a Difference?

Background: The purpose of this study was to evaluate whether there were differences in patient-reported outcomes, operative times, satisfaction scores, and complications between patients undergoing total hip arthroplasty (THA) performed through a direct anterior approach on a specialized traction table or a regular operating room table.

Methods: Patients who underwent a direct anterior approach THA on a specialized table or a regular table with a minimum 1-year follow-up were included. Patient-reported outcome measures and THA satisfaction were recorded.

Enhancement of mediodorsal thalamus rescues aberrant belief dynamics in a mouse model with schizophrenia-associated mutation.

Optimizing behavioral strategy requires belief updating based on new evidence, a process that engages higher cognition. In schizophrenia, aberrant belief dynamics may lead to psychosis, but the mechanisms underlying this process are unknown, in part, due to lack of appropriate animal models and behavior readouts. Here, we address this challenge by taking two synergistic approaches.

The Identification of Bee Comb Cell Contents Using Semiconductor Gas Sensors.

Beekeeping is an extremely difficult field of agriculture. It requires efficient management of the bee nest so that the bee colony can develop efficiently and produce as much honey and other bee products as possible. The beekeeper, therefore, must constantly monitor the contents of the bee comb.

Strong enhancement of magnetic ordering temperature and structural/valence transitions in EuPdS under high pressure.

We present a comprehensive study of the inhomogeneous mixed-valence compound, EuPdS, by electrical transport, X-ray diffraction, time-domain Eu synchrotron Mössbauer spectroscopy, and X-ray absorption spectroscopy measurements under high pressure. Electrical transport measurements show that the antiferromagnetic ordering temperature, , increases rapidly from 2.8 K at ambient pressure to 23.

Circuit-specific gene therapy reverses core symptoms in a primate Parkinson's disease model.

Parkinson's disease (PD) is a debilitating neurodegenerative disorder. Its symptoms are typically treated with levodopa or dopamine receptor agonists, but its action lacks specificity due to the wide distribution of dopamine receptors in the central nervous system and periphery. Here, we report the development of a gene therapy strategy to selectively manipulate PD-affected circuitry.

Stroke Inpatient Rehabilitation Environments: Aligning Building Construction and Clinical Practice Guidelines Through Care Process Mapping.

Background: Stroke inpatient rehabilitation is a complex process involving stroke survivors, staff, and family utilizing a common space for a shared purpose: to optimize recovery. This complex pathway is rarely fully described. Stroke care is ideally guided by Clinical Practice Guidelines, and the rehabilitation built environment should serve to optimize care delivery, patient and staff experience.

The Tungsten-Promoted Synthesis of Piperidyl-Modified -Methylphenidate Derivatives.

Due to its efficacy as a dopamine receptor agonist, methylphenidate (MPH) is of interest as a potential therapeutic for cocaine addiction. While numerous derivatives of MPH have been investigated for their potential medicinal value, functionalization of the piperidine ring has not been explored. The pyridine borane ligand in WTp(NO)(PMe)(η-pyBH) is dearomatized by the metal and can be elaborated to the analogous η-mesylpyridinium complex.

Development and Application of a Data-Driven Signal Detection Method for Surveillance of Adverse Event Variability Across Manufacturing Lots of Biologics.

Introduction: Postmarketing drug safety surveillance research has focused on the product-patient interaction as the primary source of variability in clinical outcomes. However, the inherent complexity of pharmaceutical manufacturing and distribution, especially of biologic drugs, also underscores the importance of risks related to variability in manufacturing and supply chain conditions that could potentially impact clinical outcomes. We propose a data-driven signal detection method called HMMScan to monitor for manufacturing lot-dependent changes in adverse event (AE) rates, and herein apply it to a biologic drug.
