title: EXTERNAL FIXATORS WITH HYDROCYN GEL PINSITE DRESSING IN PREVENTION PINTRACT INFECTION: A COHORT STUDY

description: Background: Pin site infection (PSI) is a pervasive complication of external fixation, with prevention hampered by a lack of consensus on optimal care. This study evaluated the efficacy of Hydrocyn gel, a stabilized superoxidized hydrogel with anti-biofilm properties, for PSI prophylaxis. Methods: A prospective cohort study was conducted from April 2024 to December 2025. Twenty-one patients with external fixators were included: 15 used Hydrocyn gel and 6 used conventional flavin dressing (control). All performed self-dressing every three days. Patients were followed weekly for four weeks, with PSI diagnosed and graded using the Checketts-Otterburn scale. Results: The Hydrocyn group (71 pin sites) had a significantly lower per-pin infection rate of 8.4% (6/71) compared to 47.8 % (11/23) in the control group. In the Hydrocyn group, three patients developed Grade 1 infections; one resolved spontaneously, one resolved with intensified care, and one had worsening infection required surgical debridement and pin removal. The control group experienced earlier and more frequent infections, with one patient requiring early debridement and multiple cases progressing to Grade 2 and 3. No osteomyelitis was reported in either group. Conclusion: Hydrocyn gel is associated with a markedly lower incidence of pin site infection compared to standard flavin dressing in a trauma population. Its anti-biofilm action offer a promising novel strategy for PSI prevention. These findings support further investigation through randomized controlled trials to establish Hydrocyn gel as a new standard in pin-site care.

title: PolyglotFakeFacts: A multilingual dataset of fake and real news across politics, security, and social domains

description: PolyglotFakeFacts is a multilingual dataset designed to support research on the detection of fake and real news across diverse domains such as politics, geopolitics, security, social issues, and military affairs.

The research hypothesis underpinning this dataset is that linguistic and contextual markers of misinformation can be systematically identified across multiple languages, enabling the development of more robust and generalizable fake news detection models.

The dataset shows a balanced collection of human-labeled fake news articles alongside verified real news extracted from trusted media outlets. Notably, the data covers multiple languages and different thematic areas, which allows researchers to explore how misinformation manifests in diverse cultural and geopolitical contexts.

Among the key findings is that fake news articles often display recurring linguistic and structural patterns regardless of the language, while real news tends to follow more standardized journalistic conventions. This suggests that multilingual approaches to fake news detection could leverage both cross-linguistic similarities and domain-specific features.

The data was gathered through a combination of manual annotation by human experts for fake news samples and curation of real news from reliable sources. All samples were pre-processed to ensure consistent formatting, removal of duplicates, and inclusion of metadata such as language, domain, and label (fake/real).

This dataset can be interpreted and used by researchers aiming to:

- train and evaluate machine learning and deep learning models for fake news classification,

- perform cross-lingual and multilingual comparative studies,

- investigate the linguistic, semantic, and thematic characteristics of misinformation.

By providing a curated, multilingual, and domain-diverse resource, PolyglotFakeFacts enables the community to develop more transparent, explainable, and resilient AI models for combating online misinformation.

title: NOAA/WDS Paleoclimatology - Porter - Old Crow River site OC52 - PCGL - ITRDB CANA544

description: We present a new 23-site network of white spruce ring-width chronologies near boreal treeline in Old Crow Flats, Yukon Territory, Canada. Most chronologies span the last 300 years and some reach the mid-16th century. The chronologies exhibit coherent growth patterns before the 1930s. However, since the 1930s, they diverge in trend and exhibit one of two contrasting, but well-replicated patterns we call Group 1 and Group 2. Over the instrumental period (1930-2007) Group 1 sites were inversely correlated with previous-year July temperatures while Group 2 sites were positively correlated with growth-year June temperatures. At the broader northwestern North America (NWNA) scale, we find that the Group 1 and Group 2 patterns are common to a number of white spruce chronologies, which we call NWNA 1 and NWNA 2 chronologies. The NWNA 1 and NWNA 2 chronologies also share a single coherent growth pattern prior to their divergence (ca. 1950s). Comparison of the NWNA 1/NWNA 2 chronologies against gridded 20th-century temperatures for NWNA and reconstructed northern hemisphere summer temperatures (ad 1300-2000) indicates that all sites responded positively to temperature prior to the mid-20th century (at least back to ad 1300), but that some changed to a negative response (NWNA 1) while others maintained a positive response (NWNA 2). The spatial extent of divergence implies a large-scale forcing. As the divergence appears to be restricted to the 20th century, we suggest that the temperature response shift represents a moisture stress caused by an anomalously warm, dry 20th-century climate in NWNA, as indicated by paleoclimatic records. However, because some sites do not diverge and are located within a few kilometres of divergent sites, we speculate that site-level factors have been important in determining the susceptibility of sites to the large-scale drivers of divergence.

title: NOAA/WDS Paleoclimatology - Bipolar Holocene Composite Ice Core CH4, d13C, and dD Data

description: Atmospheric methane concentration shows a well-known decrease over the first half of the Holocene following the Northern Hemisphere summer insolation before it started to increase again to preindustrial values. There is a debate about what caused this change in the methane concentration evolution, in particular, whether an early anthropogenic influence or natural emissions led to the reversal of the atmospheric CH4 concentration evolution. Here, we present new methane concentration and stable hydrogen and carbon isotope data measured on ice core samples from both Greenland and Antarctica over the Holocene. With the help of a two-box model and the full suite of CH4 parameters, the new data allow us to quantify the total methane emissions in the Northern Hemisphere and Southern Hemisphere separately as well as their stable isotopic signatures, while interpretation of isotopic records of only one hemisphere may lead to erroneous conclusions. For the first half of the Holocene our results indicate an asynchronous decrease in Northern Hemisphere and Southern Hemisphere CH4 emissions by more than 30 Tg CH4 yr-1 in total, accompanied by a drop in the northern carbon isotopic source signature of about -3 per mil. This cannot be explained by a change in the source mix alone but requires shifts in the isotopic signature of the sources themselves caused by changes in the precursor material for the methane production. In the second half of the Holocene, global CH4 emissions increased by about 30 Tg CH4 yr-1, while preindustrial isotopic emission signatures remained more or less constant. However, our results show that this early increase in methane emissions took place in the Southern Hemisphere, while Northern Hemisphere emissions started to increase only about 2000 years ago. Accordingly, natural emissions in the southern tropics appear to be the main cause of the CH4 increase starting 5000 years before present, not supporting an early anthropogenic influence on the global methane budget by East Asian land use changes.

title: NOAA/WDS Paleoclimatology - Paleo-pCO2 Database Paleogene C3 Plants pCO2 Calibration Data

description: Knowledge of the past concentrations of atmospheric CO2 level (pCO2) is critical to understanding climate sensitivity to changing pCO2. Towards this, a new proxy for pCO2 has been developed based on changes in carbon isotope fractionation (D13C) in C3 land plants. The accuracy of this approach has been validated against ice-core pCO2 records, suggesting the potential to apply this proxy to other geological periods; however, no thorough uncertainty assessment of the proxy has been conducted. Here, we first analyze the uncertainty in the model-curve fit through the experimental data using a bootstrap approach. Then, errors of the five input parameters for the proxy are evaluated using sensitivity analysis; these include the carbon isotope composition of atmospheric CO2 (d13CCO2) and that of the plant material (d13Corg) for two time periods, a reference time (t = 0) and the time period of interest (t), and the value of pCO2 at time t = 0. We then propagated the errors on the reconstructed pCO2 using a Monte Carlo random sampling approach that combined the uncertainties of the curve fitting and the five inputs for a scenario in which the reference time was the Holocene with a target period for the reconstructed pCO2 during the Cenozoic. We find that the error in the reconstructed pCO2(t) increases with increasing pCO2(t), yet remains <122% (positive error) and <40% (negative error) for pCO2(t) < 1000 ppmv. The error assessment suggests that it can be used with confidence for much of the Cenozoic and perhaps the majority of the last 400 million years, which is characterized by pCO2 levels generally less than 1000 ppmv. Towards this, an application of this uncertainty analysis is presented for the Paleogene (52-63 Ma) using published data. The resulting pCO2(t) levels calculated using this method average 470 +288/-147 ppmv (1sigma, n = 75), and overlap with previous pCO2(t) estimates determined for this time period using stomata, liverwort, and paleosol proxies. The analysis presented here assumes that the paleoenvironment in which the plants grew is unknown and is determined to be the largest source of error in the reconstructed pCO2(t) levels; errors in pCO2(t) could be reduced provided independent determination of the paleoenvironmental conditions at the fossil site.

title: NOAA/WDS Paleoclimatology - North Atlantic Heinrich Layer 1 Geochemical and Stable Isotope Data

description: X-ray fluorescence (XRF) core scanning and X-ray computed tomography data were measured every 1 mm to study the structure of Heinrich Event 1 during the last deglaciation at International Ocean Discovery Program Site U1308. Heinrich Layer 1 comprises two distinct layers of ice-rafted detritus (IRD), which are rich in detrital carbonate (DC) and poor in foraminifera. Each DC layer consists of poorly sorted, coarse-grained clasts of IRD embedded in a dense, fine-grained matrix of glacial rock flour that is partially cemented. The radiocarbon ages of foraminifera at the base of the two layers indicate a difference of 1400 14C years, suggesting that they are two distinct events, but the calendar ages depend upon assumptions made for surface reservoir ages. The double peak indicates at least two distinct stages of discharge of the ice streams that drained the Laurentide Ice Sheet through Hudson Strait during HE1 or, alternatively, the discharge of two independent ice streams containing detrital carbonate. Heinrich Event 1.1 was the larger of the two events and began at ~16.2 ka (15.5-17.1 ka) when the polar North Atlantic was already cold and Atlantic Meridional Overturning Circulation (AMOC) weakened. The younger peak (H1.2) at ~15.1 ka (14.3 to 15.9 ka) was a weaker event than H1.1 that was accompanied by minor cooling. Our results support a complex history for Heinrich Stadial 1 (HS1) with reduction in AMOC during the early part (~20-16.2 ka) possibly driven by melting of European ice sheets, whereas the Laurentide Ice Sheet assumed a greater role during the latter half (~16.2-14.7 ka).
