With the rising demand for wood products and as more wood-based biorefineries enter the market, wood supply security is an increasingly pressing topic. However, the exact potential for hardwood in the market as well as its use as a substitute for softwood in production processes, remains unknown. Analyses such as multi-regional input-output, physical input-output, ex-post calculations, wood flow modelling, wood price calculations, and wood resource balance, provide a first, though rough, overview which is impaired by missing data, unresolved data contradictions, and an incomplete view of hardwood utilisation. Currently, hardwood flow models are lacking but are an essential basis for estimating hardwood supply. This paper introduces Material Flow Analysis (MFA) to evaluate hardwood flows in Germany and provides results which indicate that of 37% of the total hardwood harvested from forests are unrecorded with approximately 44% (of the total hardwood harvested) being used for direct energy utilisation (fresh fibre). Furthermore, the results of this study reveal that a considerable amount of potentially higher priced assortments are being used for energy purposes, meaning almost half of all high-quality hardwood being harvested is burnt. The MFA evaluated quality and quantity of the German hardwood potential and this revealed significant possibilities for value added production (e.g., innovative products in biorefineries using degraded highquality assortments). The methodology applied uncovered unrecorded hardwood fellings and allocated it to processing in order to systematically document and review the entire hardwood flow network within one data set, thus proving the suitability of MFA for this task.

Generalist predators are characterized as sentinel species because they are conspicuous, occupy top trophic positions of the food chain, and have life history traits that make their trophic information sensitive to ecosystem state alteration. Here, we test if changes in the trophic information of a generalist predator along an eutrophication gradient can be used to determine the regime shift of lake ecosystems between clear and turbid states and provide reliable estimates of their resilience. We find that redfin culter (Chanodichthys erythropterus) trophic information responded differently to eutrophication than traditional indicators. Trophic tipping points, reached at 14.90% coverage of macrophyte, appeared earlier than those of traditional indicators. Further, the hysteresis associated to the predator’s state characterized by prey reliance on benthic fishes of low trophic signature was found to be greater than that of the ‘macrophyte-poor’ turbid state. Conclusively, generalist predators can not only serve as sentinels of the ecosystem, but also be the last barrier to be broken through in restoring the ecosystem.

The decay of animal corpses may release various nutrients into the surrounding environment and participate in the biogeochemical cycle. However, few studies have involved the sulphur cycle in animal corpse decay. Here, we conducted an indoor control experiment at five different temperature gradients (23, 26, 29, 32 and 35 °C) to explore the change of sulphur cycling microbes and genes under corpse decay by metagenomic sequencing, metagenomic binning, and 16S rRNA sequencing. Our results showed that total sulphur content decreased by 41.82% due to decomposition. The dominant phyla of the S-cycle microbes were Proteobacteria, followed by Bacteroidetes and Acidobacteria. Corpse decay decreased the pathways involved in assimilatory sulphate reduction, sulfur oxidizing (Sox) system, organic sulphur transformation, and sulphur oxidation pathway, but increased the links between inorganic and organic sulphur transformation. The alpha diversity of sulphur cycling genes decreased with increasing temperature and the deterministic process was dominant in most of temperature gradients. The diversity of microbial community was the main driving factors of sulphur cycling genes, followed by corpse decay and temperature. We obtained 257 high-quality metagenome assembled genomes (MAGs) containing sulphur cycling genes, and the results of metagenome-assembled genomes provide evidence for the covariation of sulphur cycling genes, such as sir, cysD, cysH, and ssuC, which shared the function of assimilatory sulphate reduction. Our research reveals the pathways of microbial sulphur cycling and contributes to the understanding of the elemental cycle associated with animal corpse decay.

Published: January 2025

Access to quality education, as per the Southern African Development Community’s (SADC) vision is essential for improving the overall economic growth and development of the region. However, this vision is severely hindered by school violence, a pervasive contextual issue across multiple SADC countries. Guided by Arksey and O’Malley’s five-step framework, this proposed scoping review sought to explore the contextual factors that contribute to school violence and examine intervention strategies that have been used to mitigate school violence. Six databases will be used to search for empirical articles, including ProQuest, PubMed, Web of Science, Academic Search Ultimate, PsycINFO and MEDLINE Ultimate. Screening at the abstract, title and full-text level will be conducted by all authors, with further articles being searched on the research list of the final included full-text publications. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) will be used to report on the scoping review processes. It is hoped that this scoping review will contribute to the overall understanding of the contextual factors that contribute to school violence in the context of SADC and the intervention strategies used to curb this phenomenon. The scoping review will also identify gaps in knowledge in literature and gaps in the current intervention practices, as well as influence future research on school violence in the SADC region.

Mixed Ligand Copper Complexes of Cimetidine: Synthesis, Spectroscopic and Physico-chemical Characterization
Authors: O. Abosede Olufunso , P. Osi Stephen
Published: January 2025

The greener and cost-effective synthesis of copper complex of Cimetidine (Cime) as primary ligand with one of imidazole (imi), 2,2’-bipyridine (bpy) and 1,10-phenathroline (phen) as secondary ligands respectively are described. The synthesis involves the use of distilled water as solvent and refluxing. This method serves great advantages as it is environmentally friendly, with simple work-up procedures and short reaction time with excellent yield. The complexes were synthesized by direct dissolving of the metal salt (CuSO4) in water, followed by the addition of the cimetidine and secondary ligands where applicable, stirring and filtration. The residue was dried and collected, and the filtrate kept for slow evaporation resulting in fine crystals. The obtained products were characterized by their UV-Vis and FTIR spectra, their solubility determined in various solvents and the melting point determined with the Stuarts Melting point (SMP11). Metal complexes with formula of Cu(II)-L1L2 were deduced where L1=Cimetidine (Cime), and L2=Imidazole (Imi), Bipyridine (Bpy) or Phenathroline (Phen).

Something rocky this way comes

During the Irish Mesolithic (8000–4000 cal BC) a variety of raw materials were used by Ireland’s hunter-gatherer populations. Good quality raw materials, such as flint and chert, were associated with the Earlier Mesolithic (8000–6700 cal BC) while a diversification in raw materials was associated with the Later Mesolithic (6700–4000 cal BC) in Ireland. The majority of previous research into the raw materials used during the Mesolithic period has focused primarily on flint and secondarily on chert, and a significant proportion of this research was conducted in the northeast of Ireland. As a result of this, there is a gap in our archaeological knowledge relating to the variety of raw materials used during the Irish Mesolithic outside of this area. Therefore, this study aims to investigate the diversity of raw materials utilised in Leinster (a province stretching from the east to the southeast of Ireland) during the Mesolithic period, as well as the frequency of use of these lithologies, through the analysis of excavation reports from various Irish archaeological databases. This highlighted that approximately 13 different raw materials were used within Mesolithic Leinster. The four most commonly used materials (flint, chert, rhyolite and quartz) are then explored from a broader archaeological and geological perspective to further understand their selection and use.

We performed photometric and spectroscopic studies of three large amplitude contact binaries: NSVS 2418361, ATLAS J057.1170+31.2384, and NSVS 7377875. The amplitudes of these three systems’ light curves are more than 0.7 mag. We analyzed the light curves using the Wilson–Devinney code to yield physical parameters. The photometric solutions suggested that NSVS 7377875 belongs to an A-subtype contact binary, while the others are classified as W-subtype ones. Furthermore, the mass ratio of NSVS 7377875 is higher than 0.72, so it belongs to H-subtype contact binaries. Since their light curves have unequal height at two maxima, which is called the O'Connell effect, a dark spot on the primary component for each target was required to get a better fit of the light curves. The orbital period investigation shows that the period of NSVS 2418361 is increasing, indicating a mass transfer from the the less massive component to the more massive one, while the other targets exhibit no long-term variation. Our spectral subtraction analysis of LAMOST spectra revealed excess emissions in the H
α
line, indicating chromospheric activity in all the three targets. The Gaia distance was applied to estimate the absolute parameters of the three targets, and we obtained their evolutionary state. The relationships between the energy transfer parameter of 76 H-subtype contact binaries and their bolometric luminosity ratios, as well as their contact degree, were presented. We discovered that H-subtype systems have less efficient energy transfer rate, which corresponds to the conclusion proposed by Csizmadia & Klagyivik.

A multiwavelength, multiscale study of the Mon R2 hub–filament system (HFS) reveals a spiral structure, with the central hub containing more mass than its filaments. C18O(1–0) emission detected by the Atacama Large Millimeter/submillimeter Array (ALMA) reveals several accreting filaments connected to a molecular ring (size ∼0.18 pc × 0.26 pc). The molecular ring surrounds the infrared (IR) ring (size ~0.12 pc × 0.16 pc), which is not usually observed. The IR ring encircles IR-quiet regions and a population of embedded near-IR sources, including the massive stars IRS 1 and IRS 2. ALMA HNC(3–2) line data reveal a mirrored B-shaped feature (extent ∼19,000 au × 39,000 au) toward the eastern part of the molecular ring, suggesting expansion at ~2.25 km s−1. Distinct HNC substructures in both redshifted and blueshifted velocity components are investigated toward the B-shaped feature. The presence of these braid-like substructures in each velocity component strongly suggests instability in photon-dominated regions. A dusty shell-like feature (extent ~0.04 pc × 0.07 pc; mass ~7 M
⊙) hosting IRS 1 is identified in the ALMA 1.14 mm continuum map, centered toward the base of the B-shaped feature. The IR and dense molecular rings are likely shaped by feedback from massive stars, driven by high pressures of between 10−8 and 10−10 dyn cm−2, observed within a 1 pc range of the B0 zero-age main-sequence star powering the ultracompact H ii region. Overall, these outcomes support the idea that the Mon R2 HFS transitioned from IR-quiet to IR-bright, driven by the interaction between gas accretion and feedback from massive stars.

Recent literature reports a color deviation between observed Gaia color–magnitude diagrams (CMDs) and theoretical model isochrone predictions, particularly in the very low-mass regime. To assess its impact on cluster age determination via isochrone fitting, we quantified the color deviations for three benchmark clusters, Hyades, Pleiades, and Praesepe, both for the Gaia color (BP − RP) and (G − RP). In general, the (G − RP) color deviations are smaller than the (BP − RP) ones. Empirical color-correction functions based on these benchmarks are derived for the currently available MESA Isochrones and Stellar Tracks and PAdova and TRieste Stellar Evolution Code (PARSEC) 1.2S isochrone models. Applying the correction functions to 31 additional open clusters and 3 moving groups results in a significantly improved alignment between the isochrones and observed CMDs. With our empirical corrections, isochrones provide age estimates consistent with literature values obtained through the spectral lithium depletion boundary method, validating the effectiveness of our approach. The corresponding metallicities with PARSEC 1.2S also show a good agreement with the spectroscopic results. The empirical color-correction function we present in this work offers a tool for a consistent age determination within the full mass range of stellar clusters using the isochrone fitting method.

Type I gamma-ray bursts (GRBs) are believed to originate from compact binary mergers usually with a duration of main emission less than 2 s. However, recent observations of GRB 211211A and GRB 230307A indicate that some merger-origin GRBs could last much longer. Since they show strikingly similar properties (indicating a common mechanism), which are different from the classic “long”-short burst (e.g., GRB 060614), we find they form an interesting subclass of type I GRBs, and we suggest to name them as type IL GRB. We find that the prompt emission of type IL GRB is composed of three episodes: (1) a precursor followed by a short quiescent (or weak emission) period, (2) a long-duration main emission, and (3) an extended emission. With this burst pattern, a good candidate, GRB 170228A, was found in the Fermi/Gamma-ray Burst Monitor archive data. Temporal and spectral analyses indeed show that GRB 170228A falls in the same group with GRB 211211A and GRB 230307A in many diagnostic figures. Thus, this burst pattern could be a good reference for rapidly identifying type IL GRBs and very helpful for conducting low-latency follow-up observation. We estimated the occurrence rate and discussed the physical origins and implications for the three emission episodes of type IL GRBs. Our analysis suggests the premerger precursor model, especially the magnetar super flare model, is more favored for type IL GRBs. More observations in multiwavelength and multimessenger are required to deepen our understanding of this subclass of GRB.

We have conducted a sensitivity analysis on the mid-infrared spectral decomposition of galaxies and the modeling of the polycyclic aromatic hydrocarbon (PAH) emission spectrum with the NASA Ames PAH Infrared Spectroscopic Database (PAHdb) to assess the variance on the average galaxy PAH population properties under a grid of different modeling parameters. We find that the short-low and short-low+long-low Spitzer-IRS decomposition with PAHFIT provides consistent modeling and recovery of the 5–15 μm PAH emission spectrum. For PAHdb modeling, application of a redshift to the calculated spectra to account for anharmonic effects introduces a 15%–20% variance on the derived parameters, while its absence improves the fits by ∼13%. The 4.00-α release of PAHdb achieves the complete modeling of the 6–15 μm PAH spectrum, including the full 6.2 μm band, improving the average fitting uncertainty by a factor of 2. The optimal PAHdb modeling configuration requires selection of pure PAHs without applying a redshift to the bands. Although quantitatively the PAHdb-derived parameters change under different modeling configurations or database versions, their variation follows a linear scaling, with previously reported trends remaining qualitatively valid. PAHdb modeling of JWST observations, and JWST observations smoothed and resampled to the Spitzer-IRS resolution and dispersion have consistent PAHdb derived parameters. Decomposition with different codes, such as PAHFIT and CAFE, produce PAH emission spectra with noticeable variation in the 11–15 μm region, driving a ∼7% difference in the neutral PAH fraction under PAHdb modeling. A new library of galaxy PAH emission templates is delivered to be utilized in galaxy spectral energy distribution modeling.
Foreshock Ultralow Frequency Waves at Mars: Consequence on the Particle Acceleration Mechanisms at the Martian Bow Shock

Published: January 2025

Using Mars Atmosphere and Volatile EvolutioN Magnetometer observations, we report the first statistical study of ultralow frequency (ULF) waves at the Martian foreshock. The analyzed foreshock ULF wave events are observed in the 0.008–0.086 Hz frequency range, with nearly circular and elliptical left-handed polarization in the spacecraft reference frame. These waves are propagated quasi-parallel to the ambient magnetic field, with a moderate wave amplitude. All these properties are consistent with fast magnetosonic waves, most likely generated through the ion–ion right-hand resonant instability. In addition, our results suggest that the associated resonant backstreaming protons’ velocities parallel to the mean magnetic field in the solar wind reference frame are 1.33 ± 0.40 times the solar wind velocity. The similarity between our results and previous reports at other foreshocks may indicate the presence of a common acceleration process acting in planetary bow shocks and that is responsible for this particular backstreaming population.

Quenching of star formation plays a fundamental role in galaxy evolution. This process occurs due to the removal of the cold interstellar medium (ISM) or stabilization against collapse, so that gas cannot be used in the formation of new stars. In this paper, we study the effect of different mechanisms of ISM removal. In particular, we revised the well-known Baldwin–Philips–Terlevich (BPT) and EWHα
versus [N ii]/Hα (WHAN) emission-line ratio diagnostics, so that we could classify all galaxies, even those not detected at some emission lines, introducing several new spectral classes. We use spectroscopic data and several physical parameters of 2409 dusty early-type galaxies in order to find out the dominant ionization source (active galactic nuclei, AGNs, young massive stars, hot low-mass evolved stars, HOLMES) and its effect on the ISM. We find that strong AGNs can play a significant role in the ISM removal process only for galaxies with ages lower than 109.4 yr, but we cannot rule out the influence of weak AGNs at any age. For older galaxies, HOLMES/planetary nebulae contribute significantly to the ISM removal process. Additionally, we provide the BPT and WHAN classifications not only for the selected sample but also for all 300,000 galaxies in the Galaxy And Mass Assembly survey fields.
Evaluation of the Single-component Thermal Dust Emission Model in Cosmic Microwave Background Experiments
Authors: Liu 刘 Hao 浩 , Li 李 Jia-Rui 嘉睿 , Cai 蔡 Yi-Fu 一夫
Published: January 2025

It is well known that multiple Galactic thermal dust emission components may exist along the line of sight, but a single-component approximation is still widely used, since a full multicomponent estimation requires a large number of frequency bands that are only available with future experiments. In light of this, we present a reliable, quantitative, and sensitive criterion to test the goodness of all kinds of dust emission estimations. This can not only give a definite answer to the quality of current single-component approximations but also help determine preconditions of future multicomponent estimations. Upon the former, previous works usually depend on a more complicated model to improve the single-component dust emission; however, our method is free from any additional model, and is sensitive enough to directly discover a substantial discrepancy between the Planck High Frequency Instrument data (100–857 GHz) and associated single-component dust emission estimations. This is the first time that the single-component estimation is ruled out by the data itself. For the latter, a similar procedure will be able to answer two important questions for estimating the complicated Galactic emissions: the number of necessary foreground components and their types.
Transdimensional Inference for Gravitational-wave Astronomy with Bilby

Published: January 2025

It has become increasingly useful to answer questions in gravitational-wave astronomy using transdimensional models, where the number of free parameters can be varied depending on the complexity required to fit the data. Given the growing interest in transdimensional inference, we introduce a new package for the Bayesian inference Library (Bilby), called tBilby. The tBilby package allows users to set up transdimensional inference calculations using the existing Bilby architecture with off-the-shelf nested samplers and/or Markov Chain Monte Carlo algorithms. Transdimensional models are particularly helpful when seeking to test theoretically uncertain predictions described by phenomenological models. For example, bursts of gravitational waves can be modeled using a superposition of N wavelets, where N is itself a free parameter. Short pulses are modeled with small values of N, whereas longer, more complicated signals are represented with a large number of wavelets stitched together. Other transdimensional models have been used to describe instrumental noise and the population properties of gravitational-wave sources. We provide a few demonstrations of tBilby, including fitting the gravitational-wave signal GW150914 with a superposition of N sine-Gaussian wavelets. We outline our plans to further develop the tBilby code suite for a broader range of transdimensional problems.
Keiferia azapaensis sp. nov., the first representative of the New World micromoth genus Keiferia Busck (Lepidoptera, Gelechiidae) associated with a member of Asteraceae
Authors: Vargas Héctor
Published: January 2025

The New World micromoth genus Keiferia Busck, 1939 (Lepidoptera, Gelechiidae, Gelechiinae, Gnorimoschemini) includes 21 described species, ten of which occur in South America. Like the tomato pinworm, K. lycopersicella (Walsingham, 1897), all the species of Keiferia, whose host plants have been documented, are associated exclusively with members of the family Solanaceae.

Keiferia azapaensis sp. nov. is described and illustrated, based on adults reared from leaf miner larvae collected on the shrub Trixis cacalioides (Kunth) D. Don (Asteraceae) in the Atacama Desert, northern Chile. Despite this unusual host plant, a Maximum Likelihood analysis, based on mitochondrial DNA sequences, placed the new species within a well-supported Keiferia clade. The discovery of the trophic association between K. azapaensis sp. nov. and T. cacalioides represents the first record of a member of Asteraceae as a host plant for the micromoth genus Keiferia.

Published: January 2025

The introduction and spread of invasive insects is accelerating worldwide owing to human activities, such as trade and transportation development; in particular, ports are hubs and routes for invasive insects, including ants. We surveyed ant populations in eight ports from 2021 to 2023 using pitfall traps. A total of 316,975 ants belonging to four subfamilies, 26 genera and 44 species were identified as Tetramorium tsushimae, Lasius niger, Brachyponera chinensis and Nylanderia flavipes. The statistical analysis showed that the highest values by index were for the Incheon Port (0.25), the diversity index was for the Daesan Port (2.00), the evenness index was for the Daesan Port (0.71) and the richness index was for the Gamman Port (2.13). Non-metric multidimensional scaling analysis (NMDS) indicated that ants around the Ports of Gamman, Ulsan and Gwangyang had more dominant species than those around the other ports. Five species of alien ants, including Solenopsis invicta, Solenopsis geminata, Paratrechina longicornis, Trichomyrmex destructor and Nylanderia bourbonica were identified at Gamman Port, Paratrechina longicornis at Ulsan Port and Gwangyang Port. This study provides comprehensive insights into the distribution and status of ants around ports, offering foundational data for the early detection of alien ants to reduce the risk of their settlement and spread and to respond proactively.

Published: January 2025

Knowledge about the caddisfly fauna of Kosovo has expanded significantly in recent years; however, new species continue to be described from less-studied regions.

In this paper, we describe a new species, Tinodes lumbardhi sp. nov., from the Lumbardhi i Deçanit River in the Bjeshkët e Nemuna Mountains of Kosovo. The new species is closely related to Tinodes urdhva Olah, 2010 and Tinodes kimminsi Sykora, 1962, but differs in the shapes of segment IX, coxopodites, harpago, phallicata and the basal plate process.

Tinodes lumbardhi sp. nov. represents the sixth recorded species of the genus Tinodes Curtis, 1834, in Kosovo. The species was found in a small, isolated population within a region highly impacted by anthropogenic activities, especially the construction of hydropower plants. Tinodes lumbardhi sp. nov. was found in sympatry with some species rarely encountered in Kosovo, such as Plectrocnemia geniculata McLachlan, 1871, Rhyacophila loxias Schmid, 1970 and Rhyacophila siparantum Ibrahimi, Bilalli & Kučinić, 2021. Ongoing human activities have placed increasing pressures on the river’s ecosystem, further emphasising the conservation importance of identifying and protecting these rare and specialised species within Kosovo’s freshwater habitats.

Science-fiction et management de l’innovation
Authors: Ladetto Quentin , Michaud Thomas
Published: January 2025

La science-fiction est un imaginaire jouant un rôle crucial dans les processus économiques. Le management de l’innovation peut l’utiliser dans ses travaux de prototypage et de prospective. Les méthodes du design fiction et du science fiction prototyping l’utilisent ainsi pour stimuler la créativité des membres des organisations. La science-fiction apparait donc à la fois comme un imaginaire critique de la technostructure, mais aussi, de plus en plus souvent comme un système de représentations du futur utile au capitalisme pour stimuler l’innovation technoscientifique. Les organisations ont donc intérêt à s’appuyer sur la science-fiction pour imaginer leur avenir. Les textes regroupés dans ce numéro traitent à la fois de la manière dont les organisations utilisent la science-fiction pour innover et faire de la prospective, mais aussi des représentations des organisations dans certaines œuvres.
Discriminator-free adversarial domain adaptation with information balance
Authors: Jiang Hui , Wu Di , Wei Xing , Jiang Wenhao , Qing Xiongbo
Published: January 2025

In the realm of Unsupervised Domain Adaptation (UDA), adversarial learning has achieved significant progress. Existing adversarial UDA methods typically employ additional discriminators and feature extractors to engage in a max-min game. However, these methods often fail to effectively utilize the predicted discriminative information, thus resulting in the mode collapse of the generator. In this paper, we propose a Dynamic Balance-based Domain Adaptation (DBDA) method for self-correlated domain adaptive image classification. Instead of adding extra discriminators, we repurpose the classifier as a discriminator and introduce a dynamic balancing learning approach. This approach ensures an explicit domain alignment and category distinction, thus enabling DBDA to fully leverage the predicted discriminative information for an effective feature alignment. We conducted experiments on multiple datasets, therefore demonstrating that the proposed method maintains a robust classification performance across various scenarios.

Published: January 2025

This article presents the results of optimizing the efficiency of a hybrid photovoltaic power plant using the fuzzy MPPT algorithm adapted to PID control for voltage regulation in order to overcome the voltage dip problem. The hybrid system consists of a photovoltaic field with a power of 11.2kW, a wind generator (WIND) of 12.23kW, the diesel group is used as an emergency source in the event of a power deficit and/or a voltage drop of more than 10% compared to the reference value. For this, the maximum powers of the photovoltaic generator (GPV) and the wind turbine are extracted independently by the fuzzy logic MPPT control. In addition, the two generators are coupled to the Buck-Boost chopper for voltage regulation by “proportional integral derivative” (PID) control. The hybrid system supplies an alternating load (AC) with an active power of 11kW. The entire system is controlled using fuzzy logic control whose input variables are the variation of the GPV-WIND hybrid power and the variation of the GPV-WIND hybrid voltage. The DC-DC converters used operate continuously and at a switching frequency of 10kHz under a temperature of 50°C. The originality and the contribution of this work lies in the fact that the entire hybrid system is modeled using MATLAB, thus making it possible to study its operation. The simulation results obtained are very satisfactory and show a particular interest in the search for stability and resolution of voltage dips thanks to intelligent control.

Published: January 2025

Increasing expenses and complex economic issues raise the need to redesign healthcare in a costeffective way while retaining the quality of care. Laboratory medicine plays an indispensable role in modern health care. Optimizing appropriate laboratory test utilization could reduce healthcare cost while enhancing quality of care. Literature search was done using pub-med electronic database among the studies published between January 1975 and April 2024 with search words ‘inappropriate’, ‘utilization’ and ‘laboratory tests’. Manual search of journal services and textbooks as well as reference articles were also done. Among them, studies on the landscape of inappropriate laboratory testing, possible causes, consequences, rationale for appropriate laboratory testing, strategies to improve appropriateness and the effectiveness of the interventions were included by screening the title and abstract. Studies on imaging and blood products requests were excluded. The proportion of inappropriate tests among studies varied extensively ranging from 4.5% to 95%. Based on a meta-analysis and systematic review published in 2013, overall mean rates of over and underutilization were 20.6% and 44.8% respectively. Numerous strategies have been employed both independently and in combination to overcome inappropriate utilization of laboratory resources. Laboratory diagnostic algorithms, clinical decision support systems/tools (CDSS/CDST), interventions within computerized provider order entry (CPOE), education and guidance, audits and feedback, gate keeping strategies, harmonization of test panels and request form design, and review of offered tests are some of them. Laboratory professionals can raise awareness of the need to change practice towards more appropriate requesting behavior.
Mesenchymal stem cells in myelodysplastic syndromes, contributions to disease pathogenesis and biomarker discovery
Authors: Goonasekera H. W.
Published: January 2025

It is widely accepted that alterations in both haematopoietic stem cell compartment and the bone marrow microenvironment contribute to the pathogenesis of myelodysplastic syndromes. In order to gain insights into disease pathogenesis, a main cell type in the bone marrow microenvironment, mesenchymal stem cells, have been studied with great interest in the recent past. These cells are multipotent stem cells having the ability to differentiate in to other main resident cell types of the bone marrow such as chondrocytes, adipocytes and osteogenic cells. Their properties of plastic adherence in cell culture and characteristic cell marker expression have enabled easy isolation, characterization and used in research studies. These cells are known to interact closely with the haematopoietic stem and progenitor cells to maintain normal haematopoiesis. Their interactions are tightly regulated via many mechanisms including immunomodulation. Research studies have been done on marrow derived mesenchymal stem cells by many groups. Conflicting results regarding cell morphology, cell culture characteristics, cell proliferation and karyotype have been found. Altered haematopoietic support, immunomodulation, increased cellular senescence and genomic changes indicate that deranged mesenchymal stem cells as playing a definitive role in disease pathogenesis while providing leads to biomarker discovery in myelodysplastic syndromes. Preliminary studies on intercellular communications between mesenchymal stem cells and haematopoietic cells via extracellular vesicles have shown how mesenchymal stem cells could bring about myelodysplastic changes in the marrow. Current hypomethylating and immunomodulatory therapy were shown to have effects on stromal cells. Further studies on mesenchymal stem cells are warranted.

Pityriasis rosea (PR) is an exanthematous disease associated with the endogenous systemic reactivation of human herpesvirus (HHV)-6 and/or HHV-7. Variants of PR characterized by atypical lesion morphology, eruption course, and severe symptoms have already been described, but their prevalence is probably underestimated. We report herein two patients suffering from anorexia nervosa (AN) who developed a very rare form of purpuric PR. So far, no cases of PR in AN patients have been reported in the literature. In AN, impaired cell-mediated immunity may favor the endogenous systemic reactivation of HHV- 6 and/or HHV-7, causing PR. Furthermore, an increased level of the vascular cell adhesion molecule 1, interleukin 6, and tumor necrosis factor-α has been demonstrated in AN patients, which may be responsible for their increased vascular dysfunction.

Hyperbaric oxygen therapy (HBOT) is a non-invasive method of O2 delivery that induces systemic hyperoxia. Hyperbaric chamber consists of a pressure vessel and a compressed breathing gas supply, which can regulate internal pressure. The chamber delivers 100% O2 to patients according to predetermined protocols and is monitored by trained personnel. HBOT relies on increasing the inspired O2 fraction (fiO2) and elevating the partial pressure of O2 (pO2). O2 is typically administered at pressures between 1.5 and 3.0 ATA for 60 to 120 minutes, depending on the clinical presentation. Currently, there are 15 indications for HBOT approved by the Undersea and Hyperbaric Medicine Society, categorized into three groups: emergency medicine, wound healing acceleration, and antimicrobial effects. The present narrative review aims to elucidate the mechanisms action underlying HBOT, particularly oxy-inflammation, in various pathologies within these categories.

Hypertension management plays a crucial role in influencing the health outcomes of the elderly with high blood pressure. Various health promotion strategies have been formulated for hypertension management. However, the result has not shown an optimal reduction in the number of hypertension sufferers. An effective health promotion, such as word puzzle games, needs to be developed. Word-based puzzle games can serve as engaging health promotion tools to improve hypertension-related health behaviors among older adults and enhance their cognitive abilities. This study aims to assess the effectiveness of a word puzzle game in enhancing the knowledge, attitudes, and practices of elderly individuals regarding hypertension management. A quasi-experimental approach with a pretest-posttest control group design was used. A total of 45 participants, both in intervention and control groups, were recruited through a purposive sampling technique. Data analysis involved descriptive techniques and inferential statistics using t-test models focusing on examining three variables: knowledge, attitudes, and behaviors. The result revealed statistically significant disparities in participants' knowledge (p=0.000), attitudes (p=0.001), and behaviors (p=0.001) between the experimental and control groups after implementing the word puzzle game intervention. Using word puzzle games as health promotion tools successfully enhances older adults' understanding, perspectives, and actions regarding hypertension management. These games might be employed to strengthen the ability of older individuals to control their high blood pressure.

Chronic kidney disease (CKD) is a significant non-communicable disease with varying incidence and prevalence globally. Over the past two decades, it has emerged as one of the leading causes of mortality. In Indonesia, CKD has risen sharply and now represents one of the highest disease-related cost burdens. CKD patients, both men and women, across different age groups, face complex challenges, including the risk of hepatitis C virus (HCV) infection due to hemodialysis (HD). This cross-sectional study investigated 43 CKD patients undergoing HD twice weekly for at least one year at a regional hospital in Yogyakarta, all of whom initially tested negative for HCV. The results revealed that 58.1% of CKD patients were female, with 32.6% aged 55-65 years. Most (60.5%) had completed high school education, and 39.5% were housewives. Interestingly, 69.8% of cases were not primarily caused by kidney-related conditions. Importantly, the longer a patient undergoes HD, the higher their risk of acquiring HCV infection. Although the percentages may vary across different settings, this study highlights the urgent need for targeted infection control measures, particularly in resource-limited healthcare environments where access to preventive strategies may be constrained.

Physical activity (PA) promotes health and wellbeing of children. Our objective was to assess the prevalence and the associated sociodemographic factors of PA among schoolchildren in a Southeastern European country. This was a cross-sectional study conducted in Albania in 2022 including a nationwide representative sample of 5454 schoolchildren aged 11-15 years (≈52% girls; ≈96% response). Data on children’s PA and their sociodemographic factors were collected. Daily moderate-to-vigorous PA was more prevalent in boys, younger children and those from wealthier families (overall: ≈29%). Conversely, sedentary behaviour (moderate-to-vigorous PA ≤2 days/week) was more prevalent in girls, older children, rural children, those with unemployed parents and children from less affluent families (overall: ≈26%). Frequent vigorous PA (≥3 days/week) was more prevalent in boys, younger children and those from better-off families (overall: ≈64%). Our findings highlight potential advantages of PA engagement linked to both male gender and a higher socioeconomic status. This study underscores the need for targeted interventions to promote active lifestyles in children, particularly among groups at higher risk of sedentary behaviour which correspond to girls and disadvantaged socioeconomic categories.
