Background Patients with chronic obstructive pulmonary disease (COPD) are at high risk for developing arrhythmias due to hypoxemia, right heart failure, and the use of beta-agonist inhalers. Symptoms related to arrhythmias can often be masked or confounded by symptoms related to COPD exacerbation and remain undiagnosed. With this study, we identify the incidence of actionable arrhythmias in patients with no prior cardiology follow-up and moderate-severe COPD with continuous monitoring. Methods An automatic referral for electrophysiology (EP) consult was generated in patients with moderate-severe COPD if they endorsed one of the following: palpitations, dizziness, abnormal ECG, or near syncope. Eligible patients underwent ILR implantation after evaluation with an EP specialist and were followed via remote monitoring for 12 months. A control group of patients without COPD matched for age, sex, and implant indication were randomly selected in a 3:1 ratio. Actionable arrhythmias, defined as arrhythmias that correlated with symptoms triggered by the patient, necessitating EP intervention, were recorded for both groups. Results In this prospective cohort study, 21 patients with COPD were enrolled and compared to 63 controls. COPD patients experienced a significantly higher rate of actionable arrhythmias compared to the controls (48% vs 11%, p<0.001). EP interventions in response to actionable arrhythmias included eight patients initiated on anticoagulation, three catheter ablations, one implantable cardiac defibrillator, and one permanent pacemaker implanted. In multivariate analysis, COPD was an independent predictor of actionable arrhythmias (aOR 4.3, 95% CI 1.2-15.2, p=0.02) when adjusting for chronic kidney disease and all-cause readmissions. Conclusion: Continuous monitoring was highly effective in diagnosing significant arrhythmic events in patients with moderate-severe COPD. Awareness should be raised about the high arrhythmic risk in this population and the role of continuous monitoring should be evaluated in larger studies.

The cyber attacks by ransomware rapidly increased in frequency and sophistication, causing significant disruptions to critical infrastructure, businesses, and individuals. A novel approach is introduced through the analysis of network traffic patterns combined with machine learning techniques, enabling the early detection of ransomware activity prior to file encryption or data exfiltration. The Random Forest algorithm, utilized in this study, effectively handles high-dimensional datasets and offers accurate classification by leveraging important network traffic features such as flow duration, packet sizes, and byte transmission rates. Experimental results demonstrate the model's ability to detect ransomware traffic with high accuracy across various datasets while maintaining computational efficiency. The proposed methodology highlights the potential of machine learningbased network traffic analysis as a scalable and proactive solution for ransomware detection, providing an adaptable framework for future cybersecurity applications.

Integral transforms are essential in mathematical analysis and problem-solving across various fields. In this study, we introduce a novel modified general integral transform known as the JSN transform which overcomes the disadvantages of the several integral transforms in the Laplace family on a particular class of functions. We primarily discuss the advantages such as varying s-domain, pole shifting, varying domain of analyticity and fundamental properties of this proposed transform. Additionally, we explore its effectiveness in resolving integral and differential equations through various examples.

Rapeseed oil, derived from Brassica napus, is commonly used in both machinery lubrication and European cuisine. This study investigates a potential food allergy linked to rapeseed oil. A 21-year-old patient experienced cervical angioedema after consuming foods containing rapeseed oil. Skin prick tests, SDS-PAGE, and Western blot analyses were conducted, separating water-soluble and fat-soluble proteins of rapeseed seeds. Positive skin prick tests confirmed sensitivity, and a prick-to-prick test with rapeseed oil caused urticaria. Two distinct protein bands (37 kDa and 70 kDa) were identified in the lipid fraction, suggesting unique allergenic properties not previously documented. The patient’s allergic reactions were specifically linked to rapeseed oil, emphasizing the need for further allergen characterization to improve food allergy diagnosis and management.

Body ownership—the perception that one’s body belongs to oneself—has been explored using a rubber hand illusion, in which individuals misperceive a fake hand as their own (i.e., embodiment of the fake hand) when an unseen real hand and a visible fake hand are stroked synchronously. Thus, the movement of an embodied fake body may be represented in one’s own sensorimotor system. Using a combination of the rubber hand illusion and a motor task, we investigated whether simple movement of the embodied fake hand influenced the subsequent movement of the participants’ hand. The participants lifted their own index finger immediately upon observing the index finger lifting on the embodied (rubber hand illusion) or non-embodied (non-rubber hand illusion) fake hand (Experiment 1), and a light-emitting diode turning on near the fake hand (Experiment 2). The reaction times, peak velocities, and peak acceleration were extracted from the participants’ finger-lifting movements. In Experiment 1, the reaction time was significantly shorter in the rubber hand illusion condition than in the non-rubber hand illusion condition, suggesting the rapid facilitation effect of embodied fake hand movement on actual movement. However, no such motor facilitation was observed in Experiment 2, confirming that the improved reaction time in Experiment 1 resulted from the visual movement of the fake hand rather than attention to the fake hand itself. In contrast to the reaction time, the peak velocity and acceleration did not differ significantly in either experiment. These findings reflect the shared sensorimotor representations of illusory and actual self-movement.

The underlying causes of primary FSGS and MCD remain unknown. The aim of the study is to determine a proteomic profile capable of differentiating between MCD, FSGS, and MN in patients with nephrotic syndrome. Material and methods. The study cohort consisted of 56 participants, including individuals with confirmed diagnoses of MCD (n=10), FSGS (n=22), and MN with aPLA2R positivity (n=24). All urine samples underwent duplicate analysis using Targeted quantitative LC-MS/MS employing MRM with stable isotope-labeled peptide standards. Results. In FSGS patients, we observed elevated levels of proteins associated with podocyte damage, markers of lipid metabolism, oxidation processes, various serine proteases and their inhibitors, complement components, as well as proteins indicative of tubular cell damage and tubulo-interstitial involvement. Notably, the expression of vitronectin in podocytes and RBP4 in proximal tubular cells correlated with increased urine protein excretion in FSGS. For MCD patients, we observed an increase in СD44, afamin, corticosteroid-binding globulin, and plasma serine protease inhibitor in urine samples. Conclusion. FSGS exhibits a diverse spectrum of proteins in urine. This profile suggests a high profibrogenic potential, implicating a broad range of mechanisms. These include podocyte damage, activation of epithelial-mesenchymal transformation of resident cells, complement system activation, tubulointerstitial damage, and ECM accumulation.

Mammalian skeletal muscle is composed of different types of muscle fibers, which have different physiological and metabolic characteristics.The composition of muscle fiber types has a significant effect on the meat quality of livestock.In this study, we comprehensively analyzed the Whole transcriptome of the muscles Semitendinosus (glycolytic muscles、MS) and musculus longissimus (oxidative muscles、ML) of Lufeng cattle.Compared with glycolytic muscle, a total of 447 mRNAs, 87 lncRNAs and 18 circRNAs were differentially expressed in oxidative muscle.KEGG annotations showed that the differentially expressed mRNAs regulated by lncRNAs and circRNAs were mainly involved in PI3K-Akt, arachidonic acid metabolism, linoleic acid metabolism, calcium signaling pathway and thermogenesis signaling pathway, reflecting the difference between oxidative muscle and glycolytic muscle metabolites.In addition, regulatory networks related to muscle fiber type switching and mitochondrial energy metabolism were also constructed in the study.Our study provides new evidence for a better understanding of the molecular mechanisms underlying skeletal muscle fiber determination and meat quality characteristics in Lufeng cattle(LFC).

Coastal Enhanced Weathering (CEW) is a marine Carbon Dioxide Removal (CDR) method that adds ground alkaline minerals to shallow regions of the ocean in order to increase seawater alkalinity, i.e., its capacity for storing atmospheric CO2 as bicarbonate. While CEW is promising with regard to cost and scalability, it is an uncontained, “open-system” style of CDR, and presents significant challenges to effective measurement, reporting, and verification (MRV) of the process. In particular, quantifying how much alkalinity is released from an added amount of mineral is challenging as the minerals dissolve and release alkalinity over wide spatial and long temporal scales. Such quantification is further complicated by the fact that dissolved alkalinity is rapidly diluted below detectable concentrations. Here, we propose an approach to measure alkalinity formation that relies on solid sediment tracers to track mineral grains underwater and quantify how much they have dissolved over time. The amount of dissolution at any given point in time is proportional to the amount of alkalinity released. Thus, the approach aims to overcome the near impossible detection of alkalinity accumulation in the dissolved phase by tracking the loss of alkaline material in the solid phase. We describe a test of the fundamental aspects of this method including the measurement of the mineral and tracer content of a sediment sample, and the extent to which those measurements correlate with changes in seawater chemistry. We found that olivine dissolution significantly increased alkalinity in seawater, compared to control incubators. X-Ray Diffraction (XRD) was able to quantify the change in the olivine in the sediment (albeit with large relative errors) and automated particle counting methods were able to enumerate tracer particles when illuminated under UV-A light. These results serve as a proof-of-principle (and starting point) to further explore a promising way to measure alkalinity addition to the ocean resulting from CEW deployments.

The aim of this study was to identify the determinants of outpatient physician visits and hospitalizations in Bulgaria. In the context of disparities in distribution and scarcity of resources, as well as overutilization of hospital treatment, awareness of possible misuse or underuse of health care services may aid in improving the organisation and managing the costs in the healthcare system. The cross-sectional study analysed primary data from 1292 respondents. Determinants were selected based on the Andersen’s behavioural model. The number of outpatient physician visits (GP, specialist) as well as the number of hospitalizations in the past 12 months were used as outcome measures. Four negative binomial regressions were constructed to assess associations between the independent and the dependent variables. GP visits were positively associated with family size and trust in provider. Older age, higher education, and part-time or unemployed status were associated with lower private visits to specialists. Higher income was associated with fewer visits to the GP and specialist with a referral, while long waiting times, distance and transportation difficulties were positive predictors of more private consultations. Better self-rated health was a negative predictor of GP and specialist visits and the presence of one or more chronic conditions was associated with more outpatient physician visits and more hospital admissions. We have applied the Andersen’s behavioural model, facilitating comparative analyses based on results in different countries and health systems. Identifying the impact of different utilisation rates on population health remains a major challenge.

Objectives: The ever-growing demands on care systems have increased the reliance on Home Care Support Worker’s (HCSW’s) which has seen a shift to provision of care to community based and close to home care provision. Currently there is no clear outline of a career pathway nor career development for HCSW’s, and this lack of associated framework which recognises CPD for career progression is impacting on recruiting and retaining HCSW’s within the care sector. The aim of this scoping review is to explore the international evidence to identify the potential costs/outcomes of the development of a career pathway for HCSW, and the economic benefits connected with continual professional development (CPD). The rational for taking this approach is that the evidence to date is limited, regarding the effectiveness of systems or frameworks for a career pathway for HCSW’s and value for money. Methods: A scoping review was conducted of peer-reviewed international literature using structured searches of electronic databases (Web of Science, PubMed, MEDLINE, EMBASE, CINAHL, PsycINFO, Social Care Online, and Social Sciences Citation Index) and grey literature (Sept-Nov 2023) using key economic terms and methodologies to capture economic evidence and connected costs with HCSW career development and CPD activities. Results: Article screening of titles, abstracts and full texts was conducted by two independent reviewers (EM, ML) to minimise bias and ensure rigour along with applying a GRADE approach for literature quality. The search strategy identified peer reviewed literature which included economic issues associated with CPD and HCSW career development. Following, 17 papers were critically appraised and during the process of data extraction four key themes emerged: (1) Cost-benefits of employment and training (2) Organisational economic perspectives (3) Service economic perspectives and (4) Sector economic perspectives. Discussion: The inclusion of economic evidence within this scoping review identified that there is very limited evidence associated with economic evaluation approaches to estimate the costs and benefits of CPD and development of a career pathway for HCSW. The scoping review did identify the gaps in the evidence on the assessments of systems or frameworks for HCSW’s career pathways development and CPD opportunities. Recommendations are that future research examining this topic should include Cost Benefit Analysis (CBA) to build evidence to support CPD activity and a career pathway development for HCSWs.

The airfoil DU91-W2-150 was investigated in the Low Speed Low Turbulence Tunnel at the Delft University of Technology to study unsteady aerodynamics. This experimental study tested the airfoil under a wide range of angles of attack (AoA) from 0 ◦ to 3 1 0 ◦ at three Reynolds numbers ( Re) from 2 × 1 0 5 to 8 × 1 0 5 . Pressure on the airfoil surface was measured and Particle Image Velocimetry (PIV) measurements were conducted to capture the flow field in the wake. By examining the force coefficient and comparing the wake contours, it shows that an upwind concave surface provides a higher load compared to a convex surface upwind case, highlighting the critical role of surface shape in aerodynamics. When comparing separation at specific locations along the chord for all three Res, it is observed that as Re increases, separation tends to occur at lower angles of attack, both for positive stall and negative stall. The examination of the aerodynamic force variation indicates that, during reverse flow, fluctuations are more pronounced compared to forward flow. This is owing to separation occurring at the aerodynamic leading edge (geometric trailing edge) in reverse flow. In terms of vortex shedding frequency, the study found a nearly constant normalized Strouhal number ( St) of 0.16 across various Res and AoAs in fully separated regions, indicating a consistent pattern under these conditions. However, a slight increase in St, between 0.16 and 0.20, was observed for AoAs exceeding 180 degrees, possibly due to the convex curvature of the airfoil in the upwind direction. In conclusion, this research not only corroborates previous findings for small AoAs, but also adds new data on the aerodynamic behavior of the DU91-W2-150 airfoil under large AoAs, offering various perspectives on the effects of surface curvature, Re, and flow conditions on key aerodynamic parameters.

Plastic pollution is an ongoing environmental problem because of anthropogenic activities. Developing countries in South and Southeast Asia have witnessed an unprecedented increase in terrestrial and aquatic plastic litter and aerial micro and nano plastic pollution. The present review discusses the sources and pathways of plastic pollution in the soil, water, and air with a focus on South and Southeast Asia. In addition, the impacts of plastic pollution on terrestrial, aquatic, and airborne organisms were also analyzed. Fragmentation and degradation pathways of plastic pollutants are highly complex and unpredictable. The circulation of micro and nano plastics in the food web and accumulation in living faunal tissues raise health concerns. Challenges in curbing plastic pollution due to technical, legal, behavioral, and socioeconomic conditions were discussed. An extensive list of sustainable solutions to plastic-related hazards focusing on South and Southeast Asia is also provided.

Tumor treatment has entered a new phase because to cancer immunotherapy in recent years. For a variety of human diseases, researchers have been looking for ways to alter the immune system at different phases of treatment. Chimeric Antigen Receptor (CAR) therapy is a quickly developing cancer treatment that is a subset of adoptive cell treatments (ACT). By injecting CAR molecules into immune cells, this method genetically alters them, giving them new skills to identify cancer cells and reroute malignant tumor cells through specific actions. As a result, refractory cancers have shown significant responses. As the first line of defense against infections and malignant cells, CAR Natural Killer (NK) cells are a combination of CAR molecules and innate immune cells, more especially NK cells, which are an essential part of the innate immune system. The potential for using CAR-NK cells to treat a variety of malignant tumors has been greatly increased by their ability to target a wide range of tumor antigens via particular signaling pathways on the surface of NK cells. The targeting accuracy and cytolytic activity of NK cells against tumor cells have significantly increased due to the integration of CAR molecules that target tumor-specific antigens, increased immune cell activity, and the innate anti-tumor capabilities of NK cells. Compared to CAR-T cells, CAR-engineered NK cells have a wider choice of sources during production, may produce a variety of inflammatory cytokines, facilitate cytotoxic effects, and have less side effects after treatment. Many researchers are interested in studying and exploring NK cells through various clinical studies because of these benefits, which position them as a prospective platform for CAR-based therapy. The possibilities and difficulties of using CAR NK cells to treat cancer are clarified by this review.

Oxygen supply and oxygen uptate rate (OUR) significantly influences both the physiological state of cells and nemadectin biosynthesis by Streptomyces cyaneogriseus ssp. noncyanogenus. In this study, a real-time monitoring approach for nemadectin fermentation was developed for the first time by an on-line OUR control strategy. The effect of OUR levels during the mycelium differentiation phase on nemadectin biosynthesis was studied and optimized by adjusting feeding rates of (NH4)2SO4. Results showed that controlling the OUR at approximately 17.5 mmol·L-1·h-1 during the mycelium differentiation phase effectively enhanced nemadectin production, reaching 2805.1 μg/mL, making 129.5% increase compared to the control. This OUR control strategy was successfully scaled-up to a 500 L pilot scale, achieving the highest ever nemadectin production of 2867.3 μg/mL. These findings demonstrate that this OUR control strategy provides an effective and scalable approach for industrial nemadectin production.

In this paper, we investigate the stability of pullback random attractors for non-autonomous stochastic p-Laplacian lattice systems characterized by random viscosity and multiplicative white noise. Under suitable conditions, we first establish the existence and uniqueness of these pullback random attractors, followed by demonstrating their backward compactness. We ensure the measurability of this class of attractors by proving that two defined attractor classes are equivalent in relation to two different universes. Finally, we explore the asymptotically autonomous stability of pullback random attractors by assuming that the time-dependent external forcing term converges to a time-independent external force as the time parameter approaches negative infinity.

We report a case of acquired thrombotic microangiopathy (TMA) precipitated by an influenza A virus subtype H1N1 infection. In March of 2023, a 67-year-old man, diagnosed with relapsed and refractory multiple myeloma, developed a fever immediately following a carfilzomib infusion. The following day, he tested positive for influenza A virus subtype H1N1 via a real-time polymerase chain reaction. Two days later, he exhibited unexplained thrombocytopenia, followed by typical clinical signs of microangiopathic hemolytic anemia, leading to a diagnosis of TMA. Treatment included oseltamivir, dexamethasone, plasma exchange therapy, and eculizumab. Remarkably, 35 days post-admission, the patient fully recovered and was discharged. This case indicates a potential link between influenza A virus subtype H1N1 infection and the onset of acquired TMA, with carfilzomib possibly elevating the risk.

Non-native species are one of the greatest threats to biodiversity worldwide, due to their direct and indirect effects on native communities. There are two opposing hypotheses to explain how non-native species successfully establish outside their native range. The first posits that non-native species are closely related to local native species through environmental filtering which selects species with similar traits; the second, that non-native species are distantly related to native species in the area in which they establish due to limiting similarity which minimizes competition. We assessed support for these two hypotheses by characterising the functional trait space of bird communities in Italian cities. We surveyed 220 points in breeding and winter periods along an urbanisation gradient in six cities. We assessed the two opposing hypotheses by calculating functional diversity metrics (Functional Dispersion i.e. quantification of the distribution of functional elements in the niche space, and Contribution i.e. contribution of each species to the niche space) for each community. We then modelled these metrics in relation to the presence/absence of non-native parakeet species along the urbanisation gradient. We found that non-native parakeet species were more likely to establish in the vacant functional niche space of urban bird communities, showing marked dissimilarity to native species in terms of niche space. Our results suggest that limiting similarity is the main mechanism promoting invasions at the local scale. Urban environments offer novel opportunities that are exploited by non-native birds, minimising competition with native species. This insight into niche space processes in urban areas, which can act as centres for expansion of non-native birds into other environments, can be used when implementing management strategies to enhance environmental filtering in these areas, thus reducing the chances of further establishment of non-native species.

Montane ecosystems contribute significantly to global diversity, serving as refuges for numerous species, many of which are entirely restricted to mountainous areas. These species are particularly vulnerable to anthropogenic stressors, which are expected to result in heterogeneous shifts in elevational distributions and potential range restrictions. Here, we resurveyed the elevational ranges of birds in Tianmu Mountain, eastern China, in 2021, 60 years after the original survey in the 1960s. We aimed to determine whether the elevational shifting trends of birds in the lowland and highland regions are asynchronous and whether these trends can be predicted by species traits. Over the past 60 years, we observed the upward shifts of the upper limit of lowland birds, exhibiting range expansion. However, highland birds have generally contracted their upper limits downward, resulting in decreased range. Upslope shifts and range expansions were more pronounced in species with smaller range sizes, while widely distributed species were more likely to move downward and lose occupancy of elevational areas. Our results illustrate the heterogeneous elevational range shifts between two lowland and highland bird assemblages, highlighting the complexity of avian responses to environmental changes and the need for caution when applying conventional patterns of elevational upslope shifts to species redistribution in montane ecosystems.

Objective: Our goal was to compare sleep quality characteristics in adults with and without SCT and ADHD, as well as to thoroughly investigate the SCT-factors and sleep association. Method: The study included 274 participants (age :18-35, 70.4% female).The Adult SCT Ratings Scale, the Adult ADHD Self-Report Scale (ASRS), and the Pittsburgh Sleep Quality Index were used. Results: We found four important results: Hyperactivity/Impulsivity and daydreaming significantly impacted sleep quality. Poor sleep quality negatively impacted daydreaming and sluggishness, but not as much as ADHD symptoms. Sleep Latency and Sleep Disturbances affected daydreaming. Gender differences: 1. Poor sleep quality increased daydreaming and sluggishness in women, but had no significant effect in men. 2. Hyperactivity/Impulsivity did not affect women’s daydreaming, but increased it in men. 3. SCT symptoms were not substantially affected by age in women, but sluggishness decreased with age in men. Conclusions: Our study is one of the first studies to reveal that the sct-sleep relationship can be bidirectional. Additionally, the relationship between SCT factors and sleep may differ, as in ADHD inattention and ADHD-HI.
