Abstract
Objective The risk of endogenous infections in human immunodeficiency virus (HIV)-infected individuals increases with Candida species colonized in mouth and intestinal areas. The predisposing factors for colonization and the prevalence of different Candida spp. in HIV-infected Turkish children remain unknown. This study aimed to determine the colonization frequency and risk factors of colonization with Candida species in oral and fecal samples of HIV-infected pediatric patients in relation to a control group.
Methods Oral and feces samples of 22 HIV-infected and 52 healthy children were plated onto CHROMagar and CHROM-Pal-agar. Yeasts were identified by conventional methods, and strains with insufficient identification were identified by molecular techniques.
Results Candida spp. were detected in oral/fecal samples of 50%/68.2% HIV-infected and 36.5%/73.1% healthy children. The most common species was Candida
albicans in oral and fecal samples of HIV-infected (31.8 and 31.8%) and healthy (26.9 and 48.1%) children. The most frequently non-albicans species in oral samples was Candida dubliniensis (18.2%) in HIV-infected children and Candida parapsilosis (3.8%) in healthy children. In feces samples, C. parapsilosis, Candida glabrata, and Candida krusei were most frequent (13.6%, each) in HIV-infected patients, and Candida kefyr (11.5%) was most frequent in controls. There was a significant association between oral C. dubliniensis colonization and HIV infection (p = 0.006). Yeast carriage was not associated with gender and viral load in HIV-infected patients.
Conclusion The isolation of C. dubliniensis from oral and fecal samples of pediatric HIV patients was done for the first time in Türkiye in the present study. Additional studies are needed to clarify the factors associated with oral and fecal Candida colonization in these children.
Spontaneous Cervicothoracic Extradural Hematoma with Rare Presentation in Pediatric Patient with Stroke-Like Features in Association with COVID-19, Presenting as Management Dillemma

AbstractPresentation of cervico-thoracic extradural hematoma in pediatric age is rare with stroke-like features. Its association with COVID-19 in the active stage of the disease had not been reported and its management presents a management dilemma as COVID-19 with stroke-like features.A 14-year-old boy was referred to our institute with complaints of sudden-onset upper and middle back pain, associated with loss of sensation below the middle of the back, sudden progressive weakness of both lower limbs (power 0/5) and upper limbs (power grade-2/5), and incontinence of urine, following bouts of vomiting 12 days back. There was no history of trauma, bleeding diathesis, etc. Blood investigation was suggestive of leukocytosis, and RT-PCR test for COVID-19 was positive with raised D-dimer, serum ferritin, and C-reactive protein. MRI spine was suggestive of cervicothoracic extradural hematoma extending from C5-D3 level and compressing the spinal cord. The patient refused surgical decompression and was managed conservatively, following which he improved with power grade in limbs to 4/5.Surgical decompression is the treatment of choice but the patient can sometimes improve on medical management. Association of COVID-19 with spontaneous cervicothoracic extradural hematoma had not been reported earlier in the active stage, but its role in inducing vasculopathy and increased chances of bleeding at the uncommon site had been reported in the literature, and it may precipitate such cervical epidural hematoma.
Making Connections: Leopold’s Land Health, Indigenous Ways of Knowing, Social-Ecological Resilience, and One Health
Authors: Berkes Fikret 
Published: March 2023

Abstract
Leopold’s land health concept provides a holistic view of the relationship between human health and ecosystem health. Significantly, a similar view is found in the traditional wisdom of Indigenous peoples, as exemplified by the concept of “healthy country, healthy people”. A contemporary formulation of land health is provided by social-ecological resilience, which refers to integrated complex adaptive systems that include social (human) and ecological (biophysical) subsystems in a two-way feedback relationship. Resilience is dynamic and provides the tools for dealing with change and disasters proactively. Building resilience and using social/institutional learning for adaptive governance are relevant to One Health, as are Indigenous concepts for the maintenance of healthy relationships between humans and the ecosystem.

One Health Impact Statement
The One Health approach centers on the interdependence between the health of humans, animals, and the ecosystem. However, relevant ecosystem concepts have not been developed sufficiently for a comprehensive One Health approach, as pointed out in the editorial by Zinsstag and Crump. The basic idea behind One Health not only goes back many decades in Western science but also to the environmental perception and wisdom of traditional societies. The consideration of these connections is relevant for the development of a solid theoretical basis for One Health.

Abstract
The internal magnetic field in a ferromagnetic compound, Y2Co12P7 with T
C = 150 K, was studied with µ
+SR using a powder sample down to 2 K. The wTF-µ
+SR measurements revealed the presence of a sharp magnetic transition at T
C = 151 K, and the ZF-µ
+SR measurements clarified the formation of static magnetic order below T
C. The presence of two muon spin precession signals in the ZF-µ
+SR spectrum below T
C indicates the existence of the two different muon sites in the lattice. By considering the muon sites and local spin densities at the muon sites predicted with DFT calculations, the ordered magnetic moments of Co were successfully determined.

Abstract
We present high (> 2 T) magnetic field βNMR measurements of 8Li+ implanted in single crystals of sapphire, a commonly used backing material for other samples. From the well-resolved quadrupolar splitting, we extract the electric field gradient (EFG) at the implanted 8Li+ site. Comparison with supercell density functional theory calculations of the EFG allows us to identify the octahedral interstitial site as the most likely candidate. In contrast to the zero field βNQR spectra, where multiple singals are detected, only a single site is evident at high field. We discuss possible explanations for this discrepancy. The spin lattice relaxation is extremely slow (1/T
1 < 0.02 s−1 ) over a broad temperature range from 4 to 300 K, demonstrating that cross relaxation with the 27Al nuclear spins is quenched in such high magnetic fields.
Low Energy Measurements in Low-Energy µSR

Published: March 2023

Abstract
In the context of µSR studies on magnetic materials in the ordered state, often a strong initial depolarization is found in the zero field spectra. For transverse field measurements this is often referred to as a loss in asymmetry. In case of the low-energy µSR (LE-µSR) setup this needs a more detailed discussion since effects such as time-of-flight distribution of impinging muons, back scattering, and muon reflection will change the spectra at early times and low implantation energies (E < 3keV). These effects are well understood and reproducible allowing to correct for in any given experiment. We will discuss them and show how to correct for in experiments at low implantation energies.

Published: March 2023

Abstract
A Muon station for science, technology and industry project will be constructed at China Spallation Neutron Source. The Phase I project will provide a surface muon beam with a pulse width of 130 ns at a rate over 105
µ+/pulse. Beam intensity is the key design parameter of this project. Accurate measurement of the intensity is also essential for the calibration of the µSR spectrometer. The key to the surface muon intensity measurement is to distinguish background positrons from muons. A double-stacked scintillator detector based on PMT readout scheme has been proposed, which can determine the intensity of muons and background positrons by using pulse shape discrimination method. Detailed description of the detector principle and simulated results will be presented.
In-flight muon spin resonance and muonium interferometry
Authors: Kanda Sohtaro 
Published: March 2023

Abstract
The muon and muonium play a unique role in materials science as a tiny magnetometer and an emulator of hydrogen in matter. However, there are few examples of their application as matter waves. This is because the surface muon and its simple slowing-down in a degrader cannot keep sufficient coherence. Low-energy muons from laser ionization of muonium can be used to obtain slow muonium with small temporal and spatial spread. Like an ordinary atomic interferometer, a muonium interferometer has a variety of potential applications. For example, muonium spectroscopy using interference effects, studies of quantum interference effects such as a measurement of the Berry phase, and precise measurements of fundamental constants will be possible using muonium interferometry. In this contribution, we discuss the in-flight spectroscopy of muonium and the potential of muonium interferometry.

Abstract
The aim of the Super-MuSR project is to make maximum scientific use of the muons delivered to the MuSR arm of the ISIS muon facility. It will maximise the counting rate by doubling the detector solid angle coverage, increasing the number of detectors, and improving the counting rate of each detector. The beamline will provide switchable pulse slicing and spin rotation to improve the time resolution and make it useful for higher transverse field experiments. Here we report the scientific design of the Super-MuSR spectrometer and beamline.

Abstract
Rhenium oxides belonging to the family AReO4 where A is a metal cation, exhibit interesting electronic and magnetic properties. In this study we have utilized the muon spin rotation/relaxation (µ
+SR) technique to study the magnetic properties of the MgReO4 compound. To the best of our knowledge, this is the first investigation reported on this interesting material, that is stabilized in a wolframite crystal structure using a special high-pressure synthesis technique. Bulk magnetic studies show the onset of an antiferromagnetic (AF) long range order, or a possible singlet spin state at T
C1 ≈ 90 K, with a subtle second high-temperature transition at T
C2 ≈ 280 K. Both transitions are also confirmed by heat capacity (Cp
) measurements. From our µ
+SR measurements, it is clear that the sample enters an AF order below T
C1 = T
N ≈ 85 K. We find no evidence of magnetic signal above T
N, which indicates that T
C2 is likely linked to a structural transition. Further, via sensitive zero field (ZF) µ
+SR measurements we find evidence of a spin reorientation at T
Cant ≈ 65 K. This points towards a transition from a collinear AF into a canted AF order at low temperature, which is proposed to be driven by competing magnetic interactions.

Abstract
In an all solid state Li-ion battery, it is crucial to reduce ionic resistivity at the interface between the electrode and the electrolyte in order to enhance Li+ mobility across the interface. Recent first principles calculations predict the presence of a space-charge layer (SCL) at the interface due to the difference in the Li+ chemical potential at the interface between two different materials, as in the metal-semiconductor junction in electronic devices. However, the presence of SCL has never been experimentally observed. Our first attempt in a fresh multilayer sample, Cu(10 nm)/Li3PO4(50 nm)/LiCoO2(100 nm) on a sapphire substrate, with low-energy µ
+SR (LE µ
+SR) revealed a gradual change in the nuclear magnetic field distribution width as a function of implantation depth even across the interface between Li3PO4 and LiCoO2. This implies that the change in the field distribution width at SCL of the sample is too small to be detected by LE µ
+SR.
Muonium reaction in semiconductors and insulators: The role of the transition state
Authors: Vilão Rui C , Alberto Helena V , Ribeiro Eduardo F M , Gil João M , Weidinger Alois 
Published: March 2023

Abstract
A general scheme for the reaction of muonium with the host lattice of semiconductors and insulators is derived. We begin our considerations when the muonium has been slowed down to a kinetic energy of one to a few eV, an energy at which electron excitations across the band gap are no longer possible and the subsequent deceleration is due to elastic or inelastic processes. Elastic scattering causes energy loss in small portions, on the order of 1 ‰ of kinetic energy per scattering, and eventually leads to atomic muonium at an interstitial site. At these low energies, however, the muonium may stay at one site long enough, especially at the top of the diffusion barrier, to excite a local vibration of the nearest lattice atoms, e.g., a stretching or breathing mode, leading to the stopping of muonium. The configuration formed after the excitation of the local phonon is designated “transition state”. This state may exist for some time and may be seen in /µSR as a fast relaxing diamagnetic signal. The decay of the transition state may lead either to interstitial atomic muonium or to a bound configuration in the neutral or positive charge state. In the present paper we apply this model to Al2O3 and to a Ge-rich SiGe alloy.

Abstract
The fabrication of functional wound dressing for effective hemostasis, anti-inflammation as well as angiogenesis is of vital importance. In this paper, a three-dimensional (3D) nanofiber sponge with dimethyloxaloglycine (DMOG) loaded mesoporous spheres of derivatives of Prussian blue analogues (PBAs) was prepared (3D-PBAFeCo-DMOG). The nanostructure, composition, and mechanical properties of 3D-PBAFeCo-DMOG were characterized, showing regular nanostructure and good mechanical property. The behavior of in vitro drug release showed the DMOG could achieve long-term and stable release by encapsulating in PBAFeCo microspheres and nanofibers. In vitro coagulation experiments showed that 3D-PBAFeCo-DMOG had effective hemostasis and clotting capacities. In addition, the antioxidant capacity and cell compatibility of 3D-PBAFeCo-DMOG were confirmed. These results indicate that 3D-PBAFeCo-DMOG nanofiber sponge, as a controlled drug release system, may provide a new strategy for promoting angiogenesis and wound healing for clinical applications.

Published: March 2023

Abstract
Electrocaloric (EC) materials, presenting large adiabatic temperature change or isothermal entropy change under the application (or removal) of electric fields, offer an efficient alternative to caloric heat pumps for replacing hazardous gases used in traditional vapor-compression systems. Recently, a large EC temperature change of 5.5 K have been reported in Pb(Sc0.5Ta0.5)O3 multilayer ceramic capacitors (Nair et al 2019 Nature
575 468) thanks to its strong first-order phase transition and a temperature span of 13 K has been reported in a prototype based on these capacitors (Torelló et al 2020 Science
370 125). However, the toxicity of lead forces researchers to find eco-friendly materials exhibiting competitive EC performances. Here, we study the EC effect in lead-free BaTiO3 multilayer capacitors using an infrared camera. Unlike commercial BaTiO3 capacitors, we prepared our samples without sacrifying the first-order phase transition in BaTiO3 while a low amount of 0.2 mol% Mn was added as an acceptor dopant to improve electrical resistivity. Their EC adiabatic temperature variations show two peaks versus temperature, which match BaTiO3 two first-order phase transitions, as observed by differential scanning calorimetry. We measured a temperature drop of ∼0.9 K over a temperature range of 70 K under 170 kV cm−1, starting at 30 °C near the tetragonal-to-orthorhombic phase transition. Under the same electric field, a maximum temperature change of 2.4 K was recorded at 126 °C, at BaTiO3’s Curie temperature. Our findings suggest that further optimized BaTiO3 capacitors could offer a path for designing lead-free caloric cooling prototypes.
Caring for People With Depression: Costs Among 43 Million Commercially Insured Patients With or Without Comorbid Illnesses
Authors: Glassman Jill R , Jauregui Adam , Milstein Arnold , Kaplan Robert M 
Published: March 2023

Abstract

Background
Depression is a common comorbidity for patients with chronic medical conditions. Although the costs of treating chronic medical illness in combination with depression are believed to be significantly higher than the costs of treating each condition independently, few studies have formally modeled the cost consequences of mental health comorbidity.

Purpose
To estimate the relative magnitude of the independent and synergistic contributions to health care costs from depression diagnosis and other chronic physical health conditions.

Methods
Cross-sectional, observational study using all individuals &gt;18 years of age in the national Blue Cross Blue Shield (BCBS) Axis claims database (N = 43,872,144) from calendar year 2018. General linear models with and without interaction terms were used to assess the relative magnitude of independent and synergistic contributions to total annual health care costs of depression alone and in combination with coronary heart disease, chronic kidney disease, chronic obstructive pulmonary disease, diabetes (both types 1 and 2), hypertension, and arthritis.

Results
The incremental annual cost associated with having a diagnosis of depression was $2,951 compared to $1,986–$6,251 for the other chronic physical conditions. The interaction between depression and chronic conditions accounted for less than one-hundredth of the amount of variation in costs explained by the main effects of depression and each chronic physical condition.

Conclusions
The independent increase in total annual health care costs associated with a depression diagnosis was comparable to that of many common physical chronic conditions. This finding underscores the importance of health care service and payment models that acknowledge depression as an equal contributor to overall health care costs. The combination of depression and another chronic condition did not synergistically increase total annual health care costs beyond the increases in costs associated with each condition independently. This finding has implications for simplifying risk adjustment models.
