Published: August 2024

The high prevalence of insomnia in cancer patients leads to a significant reduction in the quality of life of those affected. A detailed record of symptoms therefore plays an essential role for further course of treatment. Which screening instruments enable identification of cancer patients with insomnia is the subject of this single-arm nonrandomized study. During the data collection period, cancer patients meeting the following criteria: self-reported tiredness and/or trouble falling or staying asleep or sleeping too much in an electronic patient-reported outcome measurement were enrolled. For further analysis, focus was placed on the Patient Health Questionnaire Depression Scale (PHQ-8), the Minimal Documentation System (MIDOS2) and the Insomnia Severity Index (ISI). Frequency, correlation, and variance analyses were conducted to identify likely predictors of insomnia. Our findings indicate a closer correlation between the screening question pertaining to sleep disorders and the ISI, compared to the question on tiredness and the ISI. The initial recording of sleep-related parameters plays an essential role for cancer patients in order to identify and treat modifiable factors as promptly as possible. For an initial assessment, we recommend asking about trouble falling or staying asleep or sleeping too much.

Published: August 2024

Spinal cord injury (SCI) is damage or trauma to the spinal cord, which often results in loss of function, sensation, or mobility below the injury site. Transcranial direct current stimulation (tDCS) is a non-invasive and affordable brain stimulation technique used to modulate neuronal circuits, which changes the morphology and activity of microglia in the cerebral cortex. However, whether similar morphological changes can be observed in the spinal cord remains unclear. Therefore, we evaluated neuronal population activity in layer 5 (L5) of M1 following SCI and investigated whether changes in the activities of L5 neurons affect microglia-axon interactions using C57BL/6J mice. We discovered that L5 of the primary motor cortex (corticospinal neurons) exhibited reduced synchronized activity after SCI that correlates with microglial morphology, which was recovered using tDCS. This indicates that tDCS promotes changes in the morphological properties and recovery of microglia after SCI. Combining immunotherapy with tDCS may be effective in treating SCI.

Published: August 2024

Accurately assigning standardized diagnosis and procedure codes from clinical text is crucial for healthcare applications. However, this remains challenging due to the complexity of medical language. This paper proposes a novel model that incorporates extreme multi-label classification tasks to enhance International Classification of Diseases (ICD) coding. The model utilizes deformable convolutional neural networks to fuse representations from hidden layer outputs of pre-trained language models and external medical knowledge embeddings fused using a multimodal approach to provide rich semantic encodings for each code. A probabilistic label tree is constructed based on the hierarchical structure existing in ICD labels to incorporate ontological relationships between ICD codes and enable structured output prediction. Experiments on medical code prediction on the MIMIC-III database demonstrate competitive performance, highlighting the benefits of this technique for robust clinical code assignment.
An in vitro evaluation of the effect of antimicrobial treatment on bovine mammary microbiota

Published: August 2024

Antimicrobial-resistant bacteria have been an increasing problem in human medicine and animal husbandry since the introduction of antimicrobials on the market in the 1940s. Over the last decades, efforts to reduce antimicrobial usage in animal husbandry have been shown to limit the development of resistant bacteria. Despite this, antimicrobial-resistant bacteria are still commonly detected and isolated worldwide. In this study, we investigated the presence of antimicrobial-resistant bacteria in bovine milk samples using a multiple approach based on culturing and amplicon sequencing. We first enriched milk samples obtained aseptically from bovine udders in the presence of two antimicrobials commonly used to treat mastitis and then described the resistant microbiota by amplicon sequencing and isolate characterization. Our results show that several commensal species and mastitis pathogens harbor antimicrobial resistance and dominate the enriched microbiota in milk in presence of antimicrobial agents. The use of the two different antimicrobials selected for different bacterial taxa and affected the overall microbial composition. These results provide new information on how different antimicrobials can shape the microbiota which is able to survive and reestablish in the udder and point to the fact that antimicrobial resistance is widely spread also in commensal species.
Molecular folding governs switchable singlet oxygen photoproduction in porphyrin-decorated bistable rotaxanes

Published: August 2024

Rotaxanes are mechanically interlocked molecules where a ring (macrocycle) is threaded onto a linear molecule (thread). The position of the macrocycle on different stations on the thread can be controlled in response to external stimuli, making rotaxanes applicable as molecular switches. Here we show that bistable rotaxanes based on the combination of a Zn(II) tetraphenylporphyrin photosensitizer, attached to the macrocycle, and a black-hole-quencher, attached to the thread, are capable of singlet oxygen production which can be switched on/off by the addition of base/acid. However, we found that only a sufficiently long linker between both stations on the thread enabled switchability, and that the direction of switching was inversed with regard to the original design. This unexpected behavior was attributed to intramolecular folding of the rotaxanes, as indicated by extensive theoretical calculations. This evidences the importance to take into account the conformational flexibility of large molecular structures when designing functional switchable systems.
Deep neural networks as variational solutions for correlated open quantum systems
Authors: Mellak Johannes , Arrigoni Enrico , von der Linden Wolfgang
Published: August 2024

In this work we apply deep neural networks to find the non-equilibrium steady state solution to correlated open quantum many-body systems. Motivated by the ongoing search to find more powerful representations of (mixed) quantum states, we design a simple prototypical convolutional neural network and show that parametrizing the density matrix directly with more powerful models can yield better variational ansatz functions and improve upon results reached by neural density operator based on the restricted Boltzmann machine. Hereby we give up the explicit restriction to positive semi-definite density matrices. However, this is fulfilled again to good approximation by optimizing the parameters. The great advantage of this approach is that it opens up the possibility of exploring more complex network architectures that can be tailored to specific physical properties. We show how translation invariance can be enforced effortlessly and reach better results with fewer parameters. We present results for the dissipative one-dimensional transverse-field Ising model and a two-dimensional dissipative Heisenberg model compared to exact values.
Ubiquitination of VE-cadherin regulates inflammation-induced vascular permeability in vivo
Authors: Wilkens Markus , Holtermann Leonie , Stahl Ann-Kathrin , Stegmeyer Rebekka I , Nottebaum Astrid F , Vestweber Dietmar
Published: August 2024

VE-cadherin is a major component of the cell adhesion machinery which provides integrity and plasticity of the barrier function of endothelial junctions. Here, we analyze whether ubiquitination of VE-cadherin is involved in the regulation of the endothelial barrier in inflammation in vivo. We show that histamine and thrombin stimulate ubiquitination of VE-cadherin in HUVEC, which is completely blocked if the two lysine residues K626 and K633 are replaced by arginine. Similarly, these mutations block histamine-induced endocytosis of VE-cadherin. We describe two knock-in mouse lines with endogenous VE-cadherin being replaced by either a VE-cadherin K626/633R or a VE-cadherin KallR mutant, where all seven lysine residues are mutated. Mutant mice are viable, healthy and fertile with normal expression levels of junctional VE-cadherin. Histamine- or LPS-induced vascular permeability in the skin or lung of both of these mutant mice are clearly and similarly reduced in comparison to WT mice. Additionally, we detect a role of K626/633 for lysosomal targeting. Collectively, our findings identify ubiquitination of VE-cadherin as important for the induction of vascular permeability in the inflamed skin and lung.

Perspectives on Hearing Aid Cost and Uptake for Prescription and Over-the-Counter Hearing Aid Users
Authors: Knoetze Megan , Manchaiah Vinaya , Oosthuizen Ilze , Beukes Eldre , Swanepoel De Wet
Published: August 2024

Purpose:

This study explored user perspectives on the relationship between hearing aid cost and uptake, as well as cost-related recommendations for others with hearing difficulties, in a sample of prescription and over-the-counter (OTC) hearing aid users.

Method:

A secondary analysis was conducted on a cross-sectional survey using qualitative content analysis to analyze responses related to the cost of hearing aids. The study included a total of 241 adult participants, comprising 179 prescription hearing aid users from the Hearing Tracker website and 62 OTC hearing aid users from the Lexie Hearing U.S. database.

Results:

Prescription users had a mean age of 66.7 years (
SD
= 13.2), including 62.0% males, 37.4% females, and 0.6% nonbinary individuals. OTC users had a mean age of 63.0 years (
SD
= 13.4), with 48.4% males and 51.6% females. Three overarching domains were identified: perceived enablers to hearing aid uptake related to the cost, perceived barriers to hearing aid uptake related to the cost, and recommendations to others with hearing difficulties related to the cost, with 14 categories recognized for prescription users and 12 for OTC users. Both groups identified the high cost of hearing aids and lack of insurance coverage as significant barriers to uptake. Many prescription users reported external support (e.g., financial support and health insurance coverage) as an enabler, while OTC users frequently mentioned the affordability of OTC devices. The most common recommendation among prescription users was to seek professional support, whereas OTC users recommended researching hearing aids before making a purchase.

Conclusions:

Cost and insurance coverage consistently emerge as primary barriers to hearing aid adoption for both prescription and OTC users. To foster greater accessibility, initiatives should target these financial obstacles. Additional research is warranted on the relationship between hearing aid cost and uptake, especially among OTC users and those seeking financial assistance.

Authors: Smiley Carla S. , Murphy Brandi A.
Published: August 2024

Purpose:

The purpose of this clinical focus article is to convey the significant role that mobile audiology could have in the public health space and discuss how mobile audiology can overcome obstacles that hinder access to traditional audiological care. This article also introduces strategies for delivering innovative audiological care.

Method:

The article is drawn from the authors' personal research, business, and clinical experiences. It describes the variations in mobile audiology that could aid in improving health care outcomes, identifying underserved areas, identifying barriers, implementing innovative solutions to overcome barriers, limitations of mobile audiology, and implications for optimized hearing health care.

Conclusions:

Mobile audiology services may play a vital role in public health programs and initiatives by bringing hearing health care to underserved communities, promoting accessibility, and addressing hearing health care concerns that disproportionately impact vulnerable populations. Mobile audiology services extend beyond the conventional concept of service delivery and can reduce barriers that prevent access to hearing health care, such as lack of transportation, geographical conditions/distance, time, lack of insurance coverage for evaluation/treatment, lack of qualified hearing health professionals, and financial constraints. Various services can be offered through mobile audiology, such as comprehensive screenings, diagnostic evaluations, and rehabilitation services/interventions. Mobile audiology services provide patients with the intervention necessary to improve communication abilities, quality of life, and overall health care outcomes.

Transitional millisecond pulsars (tMSPs) represent a dynamic category of celestial sources that establish a crucial connection between low-mass X-ray binaries and millisecond radio pulsars. These systems exhibit transitions from rotation-powered states to accretion-powered ones and vice versa, highlighting the tight evolutionary link expected by the so-called recycling scenario. In their active phase, these sources manifest two distinct emission modes named high and low, occasionally punctuated by sporadic flares. Here, we present high-time-resolution spectroscopic observations of the binary tMSP J1023+0038, in the sub-luminous disc state. This is the first short-timescale (∼1 min) optical spectroscopic campaign ever conducted on a tMSP. The campaign was carried out over the night of June 10, 2021 using the Gran Telescopio Canarias. The optical continuum shows erratic variability, without clear evidence of high and low modes or of orbital modulation. Besides, the analysis of these high-temporal-cadence spectroscopic observations reveals, for the first time, evidence for a significant (up to a factor of ∼2) variability in the emission line properties (equivalent width and full width half maximum) over a timescale of minutes. Intriguingly, the variability episodes observed in the optical continuum and in the emission line properties seem uncorrelated, making their origin unclear.
Formation of planetary atmospheres

Published: August 2024

To investigate impact vaporization for planetary atmosphere formation, we have studied the thermodynamic state generated by the shock wave due to a high-velocity impact, called the shock field. We have carried out iSALE simulations for high-velocity vertical impacts using ANEOS for an equation-of-state (EoS) model. To understand the shock fields obtained from simulations, we have investigated the contribution of the thermal and cold terms in the EoS model on the Hugoniot curves. Although the thermal and cold terms are important for the pressure, the internal energy is mainly determined by the thermal term. We thus assume a simple EoS determined by the thermal term and then analytically derive the shock internal-energy field, which reproduces the results of simulations well. Using the analytical solution of internal energy and the Hugoniot curve, we have derived the shock pressure field analytically as well. The analytical solutions for internal energy and pressure are valid even for impact velocities as low as the sound speed. The solution is good for the vertical direction or within the angles of about 60 degrees. We have applied the solution to impact vaporization for the formation of planetary atmospheres. This gives good estimation of reformation of the planetary atmospheres of Earth sized planet.

Context. Near-Earth objects (NEOs) on an impact course with Earth can move at high angular speeds. Understanding their properties, including their rotation state, is crucial for assessing impact risks and mitigation strategies. Traditional photometric methods face challenges in accurately collecting data on fast-moving NEOs.

Aims. This study introduces an innovative approach to aperture photometry, tailored to analyzing trailed images of fast-moving NEOs. Our primary aim is to extract rotation state information for fast rotators.

Methods. We applied our approach to the trailed images of three asteroids: 2023 CX1, 2024 BX1, and 2024 EF, which were either on a collision course or on a close fly-by with Earth, resulting in high angular velocities. By adjusting the aperture size, we controlled the effective instantaneous exposure time of the asteroid to increase the sampling rate of photometric variations. This enabled us to detect short rotation periods that would be challenging to derive with conventional methods.

Results. Our analysis shows that trailed photometry significantly reduces the overhead time associated with CCD readout, enhancing the sampling rate of the photometric variations. We demonstrate that this technique is particularly effective for fast-moving objects, providing reliable photometric data when the object is at its brightest and closest to Earth. For asteroid 2024 BX1, we detect a rotation period of 2.5888 ± 0.0002 seconds, the shortest ever recorded. We discuss under what circumstances it is most efficient to use trailed observations coupled with aperture photometry for studying the rotation characteristics of NEOs.

Context. NGC 6558 is a low-galactic-latitude globular cluster projected in the direction of the Galactic bulge. Due to high reddening, this region presents challenges in deriving accurate parameters, which require meticulous photometric analysis. We present a combined analysis of near-infrared and optical photometry from multi-epoch high-resolution images collected with Gemini-South/GSAOI+GeMS (in the J and KS filters) and HST/ACS (in the F606W and F814W filters).

Aims. We aim to refine the fundamental parameters of NGC 6558, utilising high-quality Gemini-South/GSAOI and HST/ACS photometries. Additionally, we intend to investigate its role in the formation of the Galactic bulge.

Methods. We performed a meticulous differential reddening correction to investigate the effect of contamination from Galactic bulge field stars. To derive the fundamental parameters – age, distance, reddening, and the total-to-selective coefficient – we employed a Bayesian isochrone fitting. The results from high-resolution spectroscopy and RR Lyrae stars were implemented as priors. For the orbital parameters, we employed a barred Galactic mass model. Furthermore, we analysed the age-metallicity relation to contextualise NGC 6558 within the Galactic bulge’s history.

Results. We studied the impact of two differential reddening corrections on the age derivation. When removing as much as possible of the Galactic bulge field star contamination, the isochrone fitting combined with synthetic colour-magnitude diagrams gives a distance of 8.41−0.10+0.11 kpc, an age of 13.0 ± 0.9 Gyr, and a reddening of E(B − V) = 0.34 ± 0.02. We derived a total-to-selective coefficient of RV = 3.2 ± 0.2 thanks to the simultaneous near-infrared–optical synthetic colour-magnitude diagram fitting, which, aside from errors, agrees with the commonly used value. The orbital parameters showed that NGC 6558 is confined within the inner Galaxy and it is not compatible with a bar-shape orbit, indicating that it is a bulge member. Assembling the old and moderately metal-poor ([Fe/H] ∼ −1.1) clusters in the Galactic bulge, we derived their age-metallicity relation with star formation starting at 13.6 ± 0.2 Gyr and effective yields of ρ = 0.05 ± 0.01 Z⊙.

Conclusions. The old age derived for NGC 6558 is compatible with other clusters with similar metallicity and a blue horizontal branch in the Galactic bulge, which constitute the moderately metal-poor globular clusters. The age-metallicity relation shows that the starting age of star formation is compatible with the age of NGC 6558, and the chemical enrichment is ten times faster than the ex situ globular cluster branch.
Intrinsic line profiles for X-ray fluorescent lines in SKIRT

Published: August 2024

Context. X-ray microcalorimeter instruments are expected to spectrally resolve the intrinsic line shapes of the strongest fluorescent lines. X-ray models should therefore incorporate these intrinsic line profiles to obtain meaningful constraints from observational data.

Aims. We included the intrinsic line profiles of the strongest fluorescent lines in the X-ray radiative transfer code SKIRT to model the cold-gas structure and kinematics based on high-resolution line observations from XRISM/Resolve and Athena/X-IFU.

Methods. The intrinsic line profiles of the Kα and Kβ lines of Cr, Mn, Fe, Co, Ni, and Cu were implemented based on a multi-Lorentzian parameterisation. Line energies are sampled from these Lorentzian components during the radiative transfer routine.

Results. In the optically thin regime, the SKIRT results match the intrinsic line profiles as measured in the laboratory. With a more complex 3D model that also includes kinematics, we find that the intrinsic line profiles are broadened and shifted to an extent that will be detectable with XRISM/Resolve; this model also demonstrates the importance of the intrinsic line shapes for constraining kinematics. We find that observed line profiles directly trace the cold-gas kinematics, without any additional radiative transfer effects.

Conclusions. With the advent of the first XRISM/Resolve data, this update to the X-ray radiative transfer framework of SKIRT is timely and provides a unique tool for constraining the velocity structure of cold gas from X-ray microcalorimeter spectra.
Automatic Identification and Evaluation of Building Clusters for Optimal District Heating Networks Phasing

Published: August 2024

Considering future city changes when designing district heating networks can be tedious. This paper tackles this problem by automatically identifying potential future building clusters connections, and evaluating relevant financial and planning criteria. The methodology uses open GIS data for cluster identification and building heat demand estimation, and thermal-hydraulic models for simulating the network. On a neighbourhood scale, area characteristics such as total heat demand, distance to source, and road surface type mainly affect the decision of where to expand the network to. However, on a street scale, the sizing and location of the initial network mainly affect the network’s phasing.
