  • Younger patients with prior self-harm were more likely to present after suicide attempts

    What the study found

    The study found that, in this hospital-based psychiatry sample, patients evaluated after a suicide attempt were more often younger and had more prior self-harm-related history than patients seen for other psychiatric reasons. The authors also report that previous non-suicidal self-injury, previous suicide attempt, depressive disorder, personality disorder, and recent life stressors were associated with suicide attempts.

    Why the authors say this matters

    The authors conclude that psychiatric consultation in a general hospital is a crucial opportunity for comprehensive assessment of suicide risk factors and early intervention. They suggest that younger people with a history of suicidal behaviors and non-suicidal self-injury should be prioritized for targeted preventive strategies.

    What the researchers tested

    The researchers analyzed psychiatric consultation data from the University Hospital of Perugia. They used the Columbia Suicide Severity Rating Scale to assess suicidal ideation, suicide attempts, and non-suicidal self-injury, then compared patients referred after a suicide attempt with those referred for other psychiatric reasons using bivariate analyses and a logistic regression model with Firth's penalized likelihood.

    What worked and what didn't

    Among 373 patients, 129 were evaluated after a real, interrupted, or aborted suicide attempt. In the suicide-attempt group, females and younger patients were more common, and there were higher rates of family psychiatric history, previous suicide attempt, previous non-suicidal self-injury, recent life stressors, and current depressive or personality disorders. In the regression model, previous non-suicidal self-injury, previous suicide attempt, depressive disorder, personality disorder, and recent life stressors were positively associated with suicide attempt, while age was negatively associated.

    What to keep in mind

    This was a single-center analysis from one hospital psychiatric consultation setting, so the findings are specific to that sample. The abstract does not describe follow-up, treatment outcomes, or whether the identified risk markers improve prevention when used in practice.

    • In this sample of 373 psychiatric consultations, 34.6% were for a suicide attempt.
    • Patients seen after a suicide attempt were more often younger and female.
    • Previous non-suicidal self-injury and previous suicide attempt were associated with suicide attempt status.
    • Depressive disorder, personality disorder, and recent life stressors were also associated with suicide attempt status.
    • The authors say hospital psychiatric consultation is an important point for suicide risk assessment.

  • Temporal-clique queries are evaluated more efficiently

    What the study found

    The study found that temporal-clique subgraph queries can be evaluated more efficiently when both the query's topology and time-window overlap are used together. The authors report that their approach outperforms existing techniques while adding minimal storage overhead.

    Why the authors say this matters

    The authors say this matters because temporal-clique subgraph pattern matching has applications in social networks, life sciences, smart cities, and telecommunications. They suggest that improving processing for queries with both temporal and structural constraints can make this kind of analysis more practical.

    What the researchers tested

    The researchers studied temporal-clique subgraph pattern matching, where edges must match a specific graph structure and also overlap within a specified time window. They proposed a new query-processing approach with a specialized multi-way join operator, an optimized query planner, and a cardinality estimator, plus additional optimizations.

    What worked and what didn't

    The approach was reported to better use both topological selectivity and temporal selectivity in the query. The experiments showed substantial performance gains over state-of-the-art methods, and the abstract says the method required minimal extra storage. Existing subgraph matching techniques were described as inefficient for these combined queries.

    What to keep in mind

    The abstract does not describe specific datasets, experimental settings, or detailed numerical results. It also does not provide limitations beyond noting that existing techniques are inefficient for these combined temporal and structural queries.

    • Temporal-clique subgraph queries combine structural graph matching with a time-window constraint.
    • The authors propose a new query-processing approach with a multi-way join operator, query planner, and cardinality estimator.
    • The paper reports substantial performance improvement over state-of-the-art techniques.
    • The method is described as requiring minimal additional storage overhead.
    • Applications mentioned include social networks, life sciences, smart cities, and telecommunications.

  • Trace mineral levels varied by species in free-living herbivores

    What the study found

    The study found that liver trace element profiles differed by species in free-living large herbivores, with red deer showing comparatively higher copper and horses showing elevated iron and lead. It also found temporal declines in some elements, including iron and lead, across all species.

    Why the authors say this matters

    The authors conclude that species- and context-specific reference intervals are needed when assessing health in free-living herbivores, because the study's estimated intervals differed from livestock standards. The findings indicate that mineral surveillance can support wildlife health assessment, track long-term environmental changes, and inform management decisions in nature reserves.

    What the researchers tested

    The researchers used a long-term post-mortem monitoring system based on routine liver sampling from Heck cattle, Konik horses, and red deer in the Oostvaardersplassen nature reserve in the Netherlands. They measured trace minerals and heavy metals with inductively coupled plasma mass spectrometry, including arsenic, cadmium, chromium, cobalt, copper, iron, lead, manganese, molybdenum, nickel, selenium, vanadium, and zinc.

    What worked and what didn't

    The monitoring system identified reference intervals and showed clear species-specific patterns in liver trace element concentrations. It also detected seasonal and age-related variation, as well as declining trends in some elements over time, including iron and lead across all species. Reference intervals estimated in the study differed from livestock standards, especially for copper and selenium.

    What to keep in mind

    The abstract does not describe detailed study limitations beyond noting that the findings come from a minimally managed, multi-species population at one reserve. The results are specific to the species, site, and monitoring system described in the study.

    • Red deer had comparatively higher copper levels.
    • Horses had elevated iron and lead levels.
    • Iron and lead declined over time across all species.
    • Seasonal and age-related variations were observed.
    • Reference intervals differed from livestock standards, especially for copper and selenium.

  • Xitsonga literary texts use varied terms of address

    What the study found

    The study found that Xitsonga literary texts use a diverse range of terms of address, including kinship terms, personal names, hypocoristic names, nicknames, personal titles, pronouns, teknonyms, and terms of endearment. Their use varies with social relationships, degrees of formality, and context.

    Why the authors say this matters

    The authors conclude that the findings provide insight into the pragmatic uses of address forms in Xitsonga literature. They also say the forms fulfill socio-cultural functions and help maintain social relations in written discourse.

    What the researchers tested

    The researchers used a descriptive qualitative approach from a sociolinguistic perspective. They analyzed content from three Xitsonga literary works: Ndlandlalati ya Malenga, Byi le Tintihweni, and Xivoni xa Vutomi, using politeness theory as the guiding framework.

    What worked and what didn't

    The analysis identified several kinds of address forms in the texts, with variation in how they were used across situations. The findings indicate that these forms are shaped by social environment and by broader sociolinguistic and socio-cultural norms.

    What to keep in mind

    The summary describes only three literary works, so the findings apply to those texts rather than all Xitsonga writing. The abstract does not report statistical testing or describe limitations in detail.

    • Xitsonga literary texts contain multiple kinds of address forms.
    • The forms include kinship terms, names, titles, pronouns, teknonyms, and endearments.
    • Usage changes with social relationship, formality, and context.
    • The study uses politeness theory to interpret address forms.
    • The analysis is based on three Xitsonga literary works.

  • Nitrogen split ratio affected lodging resistance and yield in winter wheat

    What the study found

    The study found that changing how nitrogen fertilizer was split between basal application and topdressing affected the second basal internode, a key load-bearing stem segment in winter wheat. Under the 3:7 nitrogen split, lodging resistance improved and yield increased compared with the control split.

    Why the authors say this matters

    The authors say the findings provide agronomically applicable nitrogen management guidelines for high-yield winter wheat systems. The study suggests that managing the second basal internode may help balance lodging resistance and yield.

    What the researchers tested

    The researchers ran field experiments over two seasons with three winter wheat cultivars and three nitrogen split ratios: 5:5, 3:7, and 7:3, with a constant total nitrogen rate of 270 kg ha−1. They measured the second basal internode’s mechanical properties, morphology, anatomy, and composition, and used structural equation modeling to analyze the relationships among them.

    What worked and what didn't

    Across all treatments, the culm lodging resistance index decreased by 41.8% from flowering to milk stage. The 3:7 treatment significantly improved lodging resistance at all stages and increased yield by 12.2% compared with the control 5:5 treatment, while the study reports lodging-treatment values of culm lodging resistance index between 0.11 and 0.15 at the milk stage.

    What to keep in mind

    The abstract describes field experiments in the North China Plain under a fixed total nitrogen rate, so the findings are limited to that setting as presented. The available summary does not describe additional limitations beyond this scope.

    • The second basal internode was treated as a key load-bearing structure for lodging resistance in winter wheat.
    • A 3:7 basal-to-topdressing nitrogen split improved culm lodging resistance index at all stages.
    • The 3:7 treatment increased yield by 12.2% compared with the 5:5 control treatment.
    • Culm lodging resistance index fell by 41.8% from flowering to milk stage across treatments.
    • Structural equation modeling supported a composition–structure–lodging resistance–yield chain.

  • HPTLC method validated for gentamicin sulphate in ointments

    What the study found

    The study found that a stability-indicating high-performance thin-layer chromatography (HPTLC) method could identify and quantify gentamicin sulphate in an ointment formulation. The method separated gentamicin sulphate bands without interference from ointment excipients or degradation products.

    Why the authors say this matters

    The authors conclude that the method is simple and convenient for quality control of gentamicin ointments. They also note that it does not require sample pre-treatment, such as extraction from the ointment base.

    What the researchers tested

    The researchers developed and validated an HPTLC method using silica gel 60 F254 plates as the stationary phase and methanol:chloroform:ammonia solution (25%) in a 1:1:1 ratio as the mobile phase. They dissolved the ointment sample in chloroform:methanol (9:1) and validated the method according to International Council for Harmonisation guidelines.

    What worked and what didn't

    The method showed specificity by separating all three bands of gentamicin sulphate without interference from excipients or degradation products under photolytic, photolytic and oxidative, oxidative, acidic, and alkaline stress conditions. It was linear over 50–300 ng/band with R2 ≥ 0.99, and the reported limits of detection and quantification were 7.10 ng and 21.53 ng, respectively.

    What to keep in mind

    The available summary describes validation results for one ointment formulation and does not provide broader testing beyond that context. Other limitations are not described in the abstract.

    • The study validated a stability-indicating HPTLC method for gentamicin sulphate in an ointment formulation.
    • The method separated gentamicin sulphate from ointment excipients and degradation products under several stress conditions.
    • Linearity was reported across 50–300 ng/band with R2 ≥ 0.99.
    • The reported limits were 7.10 ng for detection and 21.53 ng for quantification.
    • No sample pre-treatment or extraction from the ointment base was required.

  • Blockchain can support traceability and verification in agri-food systems

    What the study found

    The study found that blockchain can strengthen product-level traceability and improve verification of sustainability and safety claims in agri-food systems. It also found that blockchain may act as an enabling digital layer for sustainable and resilient food systems.

    Why the authors say this matters

    The authors conclude that blockchain should be embedded in wider, participatory strategies that align digital innovation with long-term sustainability and equity goals in the agri-food sector. They say this is relevant to building sustainable, inclusive, and resilient food systems under global megatrends.

    What the researchers tested

    The researchers used a structured literature review of peer-reviewed and industry sources. They also analyzed a curated dataset of European and international pilot implementations, and used stakeholder-based foresight activities and scenarios from the TRUSTyFOOD project to examine links between blockchain adoption and megatrends.

    What worked and what didn't

    Evidence from the literature and pilot cases indicates that blockchain can improve transparency, certification, supply chain coordination, traceability, and verification of sustainability and safety claims. Cross-case analysis also identified persistent constraints, including heterogeneous technical standards, limited interoperability, high deployment costs for smallholders, and governance risks from consortium-led platforms.

    What to keep in mind

    The abstract does not describe detailed study limitations beyond the constraints found in the cross-case analysis. It also does not provide enough information here to determine how broadly the pilot outcomes apply beyond the cases reviewed.

    • Blockchain was found to improve product-level traceability in agri-food systems.
    • The evidence reviewed also linked blockchain with better verification of sustainability and safety claims.
    • The study identified barriers such as poor interoperability, varied technical standards, and high costs for smallholders.
    • Governance risks were noted for consortium-led blockchain platforms.
    • The authors say blockchain should be part of broader participatory strategies for sustainability and equity.

  • Sandwich panel explosion resistance depends strongly on core and bonding properties

    What the study found

    The study finds that several internal features of sandwich panels are the main factors affecting their dynamic response and anti-explosion performance. In particular, the core characteristics and interfacial bond performance play major roles.

    Why the authors say this matters

    The authors say this matters because sandwich panels are an important route to lightweight structures with high anti-explosion performance. They conclude that better understanding of material behavior and structural failure could support more effective design optimization.

    What the researchers tested

    This is a research article summarizing progress on anti-explosion performance and optimization design methods for sandwich panels in multiple explosion scenarios. The abstract discusses sandwich panels, their energy absorption behavior, and factors linked to their performance, rather than reporting a single experiment in detail.

    What worked and what didn't

    The abstract reports that core characteristics, core combination, core thickness, front face sheet thickness, structural strength and stiffness, and interfacial bond performance are key internal factors. It also states that interfacial bond performance has a great influence on anti-explosion performance. At the same time, the relationship between material properties and anti-explosion performance remains unclear, and research on material failure mechanisms is lacking.

    What to keep in mind

    The abstract does not provide detailed experimental methods, sample types, or specific quantitative results. It also notes that multi-factor collaborative analysis is limited, which restricts conclusions about how structure and material properties should be optimized.

    • Sandwich panels are described as important for lightweight anti-explosion structures.
    • Core characteristics and interfacial bond performance are identified as major factors affecting performance.
    • Core thickness, front face sheet thickness, strength, and stiffness are also listed as important internal factors.
    • The abstract says the relationship between material properties and anti-explosion performance is still unclear.
    • The authors note a lack of research on material failure mechanisms and multi-factor collaborative analysis.

  • Energy crisis reshaped food, transition, and poverty sectors

    What the study found

    The review found that the energy crisis triggered by the Russia–Ukraine war changed the food market, the energy transition, and energy poverty in different ways. The abstract says it accelerated the shift toward renewables, increased inflationary pressure in the global food supply chain, and worsened energy vulnerability for low-income populations.

    Why the authors say this matters

    The authors say the complexity of the energy crisis and the changing energy landscape create a need to capture what is already known and to identify future research avenues. The study suggests this is especially relevant for EU Member States, which were most affected because of their dependence on Russian fossil fuels.

    What the researchers tested

    The researchers conducted a systematic literature review on the impacts of the energy crisis after the start of the Russia–Ukraine war. They compiled knowledge across three areas: the food market sector, the energy transition sector, and the energy poverty sector.

    What worked and what didn't

    According to the review, the crisis provided impetus for a faster transition to renewables. At the same time, it triggered significant inflationary pressure in the global food supply chain and intensified energy vulnerability for low-income populations.

    What to keep in mind

    This is a review article, so it summarizes existing literature rather than reporting new primary data. The abstract does not describe specific study limitations beyond the scope of the three sectors reviewed.

    • The review covers the food market, energy transition, and energy poverty after the Russia–Ukraine war began.
    • The abstract says the crisis accelerated the move toward renewables.
    • It also says the crisis increased inflationary pressure in the global food supply chain.
    • Low-income populations faced greater energy vulnerability.
    • EU Member States were described as most affected because of dependence on Russian fossil fuels.

  • Nursery peer transmission shapes infant gut microbes

    What the study found

    The study found extensive baby-to-baby transmission of microbial strains in nursery groups during the first year of life. By the end of the first term, nursery-acquired strains made up a share of the infant gut microbiome comparable to strains from family.

    Why the authors say this matters

    The authors conclude that social interactions in infancy are crucial drivers of infant microbiome development. The findings indicate that transmission among babies, not only from mothers or families, helps shape the developing gut microbiome.

    What the researchers tested

    The researchers carried out a metagenomic survey, which uses DNA from mixed microbial communities to identify strains, in nursery settings. They sampled 134 people, including babies attending nursery during the first year, educators, and families, and collected 1,013 fecal samples across three facilities.

    What worked and what didn't

    They detected baby-to-baby microbiome transmission after only one month of nursery attendance, and the transmission network became more complex over the nursery year. Having siblings was associated with higher microbiome diversity and less strain acquisition from nursery peers, while antibiotic treatment was the condition most associated with increased influx of strains.

    What to keep in mind

    The abstract does not describe detailed limitations beyond the study’s nursery-based scope and first-year timeframe. The findings come from three facilities and should be read within that setting.

    • Extensive baby-to-baby strain transmission was detected in nursery groups.
    • Nursery-acquired strains reached a contribution comparable to family strains by the end of the first term.
    • Transmission continued to increase over the nursery year in a more intricate network.
    • Having siblings was linked to higher microbiome diversity and less strain acquisition from nursery peers.
    • Antibiotic treatment was the condition most associated with increased influx of strains.
