Objectives: The goal of this study was to investigate lipid goal achievement rates in very high-risk patients over six months using high-intensity rosuvastatin or rosuvastatin/ezetimibe combination lipid-lowering therapy. Methods: This prospective, observational study was conducted on the patients of 150 general and 60 specialist practices. Our analysis included 3017 patients (47% women) who completed six months of therapy. Of these, 55.5% had pre-existing cardiovascular disease, 35.6% had cerebrovascular disease, and 20.4% had peripheral vascular disease. Results: At six months, in patients receiving rosuvastatin monotherapy (20.5%), the 1.8 LDL-C achievement rate was 37%; in those taking the fix rosuvastatin/ezetimibe combination (63.7%), it was 52%, and the 1.4 level attainment proved to be 11% and 22%, respectively. The rates of LDL-C reduction of at least 50% were 32% and 42%, respectively. Overall, non-HDL-C goal achievement rates were higher than when LDL-C was calculated using the Martin–Hopkins or Sampson methods but similar to those calculated with the Friedewald formula. When patients were stratified by triglyceride quartiles, non-HDL-C goal achievement rates were significantly higher (p < 0.001) in cases with triglyceride levels below 1.2 mmol/L. Conversely, Friedewald-calculated LDL-C (F-LDL-C) goal achievement rates were significantly higher (p < 0.001) in patients with triglyceride levels above 1.7 mmol/L. Conclusions: Our findings suggest that the consistent use of fixed high-intensity statin and ezetimibe combinations can improve lipid goal achievement. However, comparing the achievement of LDL-C goals (calculated by three methods) and non-HDL-C goals also confirmed that the common practice of automatically adding 0.8 mmol/L to the calculated LDL-C value to determine non-HDL-C leads to inaccuracies, particularly in the lower triglyceride ranges.

Background/objectives: The COVID-19 pandemic affected cancer care globally. Our objective was to analyze the demographic and clinical characteristics of kidney cancer (KC) patients between the pre-COVID-19 and COVID-19 periods. We also aimed to assess how KC was discovered—incidentally or symptomatically—and identify factors predicting the mode of discovery and advanced-stage disease. Methods: This retrospective study analyzed data from 400 patients aged 18 years or older diagnosed with kidney cancer (KC) at a large regional Hungarian clinical center during two time periods: the pre-COVID-19 period (1 January 2019 to 15 March 2020) and the COVID-19 period (16 March 2020 to 13 May 2021). Demographic and clinical information, including the mode of cancer discovery, was collected for all patients. Results: During the pandemic, monthly kidney cancer diagnoses declined by 10.3%. The proportion of female patients rose significantly from 31.9% to 42.9% (p = 0.023). Incidental tumor detection decreased from 82.4% to 72.4% (p = 0.018), while symptomatic presentation increased from 14.2% to 19.4%, although not significantly (p = 0.166). Non-incidental detection was associated with a 3.42-fold increase in odds of advanced cancer pre-pandemic and a 2.03-fold increase during the pandemic. Symptomatic presentation raised these odds by 4.51 and 2.76 times, respectively. Conclusions: Our study revealed changes in kidney cancer detection during the pandemic, including a rise in the proportion of female patients and a decline in case numbers, likely due to reduced incidental findings. Non-incidental discovery and symptom presence remained predictors of advanced-stage disease, although the odds were lower. Various factors—such as changes in healthcare access and gender-related differences in health-seeking behavior—may possibly explain these changes. Our findings support the critical role of incidental detection in high-risk populations. Full article

Poppy (Papaver somniferum L.) is an important industrial plant worldwide. It is legally cultivated in seven countries around the world for the production of poppy straw or raw opium in India for alkaloid extraction. This work focused on testing different types of growth regulators and foliar nutrients to increase and stabilize basic alkaloids, mainly morphine in dry capsules. Field trials were carried out for three years (2021–2023). Selected preparations and their combinations were applied on the seeds before sowing and on the leaves during vegetation. The content of basic alkaloids in the dry capsules was analyzed by liquid chromatography. The results obtained confirmed the demonstrable effects of pre-sowing seed treatment and foliar treatment during the growing season on alkaloid content. In the experimental treatments in which the seeds were not treated but foliar treatment was applied during vegetation, more alkaloids were accumulated compared to the control (untreated seeds, not foliar treatment), but this difference was not statistically significant. The influence of the weather conditions during the experimental year on the accumulation of alkaloids was confirmed. Environmental conditions during the growing season and plant stress influenced alkaloid accumulation. An additional supply of growth regulators and foliar fertilizers reduced the stress and positively influenced the accumulation of individual alkaloids. The results obtained provide important insights into the technology of cultivating industrial poppy varieties. Full article

Changes in land use and agricultural practices have altered the resilience of plant communities and can lead to the emergence of invasive species. One of these is the perennial grass species Bothriochloa ischaemum (L.) Kleng., whose diversity-reducing effects are known from several studies. Our exploratory questions were as follows: How does the presence of B. ischaemum affect the diversity and ratio of the species of sandy grasslands? To what extent does this diversity change depend on site characteristics? The supporting studies were carried out in five low-lying sand dune slacks and six relatively higher areas in the upper-intermediate part of the dunes and on an abandoned old field located in the Hungarian Great Plain in the Carpathian Basin. The cover of vascular plant species was recorded in all sampling sites in twelve 2 by 2 m plots, and the dataset was analysed using agglomerative cluster analyses and a non-parametric Kruskal–Wallis test. Five significantly different groups were identified, separating the vegetation types of the sides of the sand dunes, the vegetation types of the dune slack and the old field, and a Stipa borysthenica Kolkov ex Prokudin-dominated vegetation type. Our results suggest that B. ischaemum is only present as small tussocks on the drier, more exposed sides of dunes, with 3.9–24.2% average coverage; is less able to outcompete Festuca vaginata Waldst. et Kit. ex Willd. and S. borysthenica; and is only able to form large tussocks mainly in the lower dune slacks, with 45.6–79.5% average coverage. Here, in the wetter areas, it achieves high cover with a considerable accumulation of litter, and it becomes a dominant species in this association. The diversity-reducing effect of B. ischaemum on old-field grasslands depends on the age of the site and on the stability of the vegetation. Full article

Background: Assessing cancer survival trends is crucial for monitoring progress in cancer management and prevention. As part of the broader HUN-CANCER EPI study, this analysis examined overall survival (OS) in the Hungarian cancer population between 2011 and 2019. Methods: Using data extracted from the Hungarian National Health Insurance Fund (NHIF) database, short- and long-term OS were estimated for various cancer types according to age, sex, and diagnostic period using Kaplan–Meier analysis. The study also identified cancer types with significant early mortality following diagnosis. Results: From 2011 to 2019, a total of 528,808 patients were diagnosed with cancer. During the 2015–2019 diagnostic period, the lowest 5-year OS rates were observed for esophageal (7.0%), pancreatic (10.7%), liver (12.5%), gallbladder (13.9%), and lung cancer (18.4%). Conversely, tumor types with better OS included testicular cancer (91.6%), thyroid cancer (89.0%), Hodgkin’s lymphoma (84.0%), melanoma (78.6%), and breast cancer (74.1%). A notable proportion of deaths occurred within 2 months of diagnosis for liver (33.2%), pancreatic (27.9%), and gallbladder cancer (29.0%). Significant early mortality within 6 months post-diagnosis was also noted for esophageal (51.3%), stomach (42.9%), and lung cancer (41.7%). Conclusions: The HUN-CANCER EPI study conducted between 2011 and 2019 provides valuable insights into cancer survival patterns in Hungary, emphasizing the importance of early detection and targeted interventions to improve patient outcomes.

In this paper, starting from abstract versions of a result of Bennett given by Niculescu, we derive new majorization-type integral inequalities for convex functions using finite signed measures. The proof of the main result is based on a generalization of a recently discovered majorization-type integral inequality. As applications of the results, we give simple proofs of the integral Jensen and Lah–Ribarič inequalities for finite signed measures, generalize and extend known results, and obtain an interesting new refinement of the Hermite–Hadamard–Fejér inequality.

This paper investigates the effects of a Corotating Interaction Region (CIR)/High-Speed Stream (HSS)-driven geomagnetic storm from 13 to 23 October 2003, preceding the well-known Halloween storm. This moderate storm exhibited a prolonged recovery phase and persistent activity due to a High-Intensity Long-Duration Continuous AE Activity (HILDCAA) event. We focus on low-latitude ionospheric responses induced by Prompt Penetration Electric Fields (PPEFs) and Disturbance Dynamo Electric Fields (DDEFs). To assess these effects, we employed ground-based GNSS receivers, Digisonde data, and satellite observations from ACE, TIMED, and SOHO. An empirical model by Scherliess and Fejer (1999) was used to estimate equatorial plasma drifts and assess disturbed electric fields. Results show a ∼120 km uplift in hmF2 due to PPEF, expanding the Equatorial Ionization Anomaly (EIA) crest beyond 20° dip latitude. DDEF effects during HILDCAA induced sustained F-region oscillations (∼100 km). The storm also altered thermospheric composition, with [[O]/[N2] enhancements coinciding with TEC increases. Plasma irregularities, inferred from the Rate of TEC Index (ROTI 0.5–1 TECU/min), extended from equatorial to South Atlantic Magnetic Anomaly (SAMA) latitudes. These results demonstrate prolonged ionospheric disturbances under CIR/HSS forcing and highlight the relevance of such events for understanding extended storm-time electrodynamics at low latitudes.

The self-similar structure-based analysis of digital images offers many new practical possibilities. The fractal dimension is one of the most frequently measured parameters if we want to use image data in measurable analyses in metric spaces. In practice, the fractal dimension can be measured well in simple files containing only image data. In the case of complex image data structures defined in different metric spaces, their measurement in metric space encounters many difficulties. In this work, we provide a practical solution for the measurement of ortho-photos—as complex image data structures—based on the spectral fractal structure based on boundary conditions (height, time, and temperature), presenting the further development of the related theoretical foundations. We will discuss the optimal flight altitude determination in detail through practical examples. For this, in addition to the structural measurements on the images, we also use the well-known image entropy in information theory. The data obtained in this way can facilitate the optimal UAS operation execution that best suits further image processing tasks (e.g., classification, segmentation, and index analysis). Full article

Background/Objectives: Hamilton and colleagues invented the soleus push-up exercise and showed that this exercise method was successful in reducing postprandial blood glucose levels in sedentary individuals. The objective of the current pilot study was to assess the efficacy of the soleus push-up in individuals with prediabetes and to evaluate the feasibility of incorporating this exercise method into their daily routine. Methods: Ten participants (mean age: 53.3 ± 2.7 years; four females, six males) with prediabetes were included in the study. Initially, participants underwent an oral glucose tolerance test (OGTT) while being sedentary to establish baseline postprandial blood glucose measurements. During a subsequent OGTT, participants concurrently performed the soleus push-up (SPU) exercise either with or without electromyographic (EMG) feedback. Blood glucose levels were measured at 15 min intervals over the two-hour duration of both OGTTs. Results: We observed that performing the SPU in a sitting position during the oral glucose tolerance test resulted in approximately a 32% reduction in postprandial glucose excursion compared to the sedentary baseline results. This effect was also present in the absence of EMG feedback. Conclusions: Our findings suggest that this repetitive, prolonged contractile muscle activity can improve metabolic regulation in prediabetic individuals without the need for a laboratory setting. SPU may be a viable and effective exercise to support metabolic health in home or work environments. However, further validation is needed with a larger sample size. Full article

The aim of this research article is to use the extended fractional operators involving the multivariate Mittag–Leffler (M-M-L) function, we provide the generalization of the Hermite–Hadamard–Fejer (H-H-F) inequalities. We relate these inequalities to previously published disparities in the literature by making appropriate substitutions. In the last section, we analyze several inequalities related to the H-H-F inequalities, focusing on generalized h-convexity associated with extended fractional operators involving the M-M-L function. To achieve this, we derive two identities for locally differentiable functions, which allows us to provide specific estimates for the differences between the left, middle, and right terms in the H-H-F inequalities. Also, we have constructed specific inequalities and visualized them through graphical representations to facilitate their applications in analysis. The research bridges theoretical advancements with practical applications, providing high-accuracy bounds for complex systems involving fractional calculus. Full article

Moringa (Moringa oleifera Lam.) is a tree that grows in tropical and subtropical regions. In this study, the plants were grown in a temperate climate zone from seeds collected at the Island of St. Lucia. Cultivation was carried out in the field and in a greenhouse in Prešov, East Slovakia. Leaf samples were taken from young plants and dried naturally. In the ethanol and hot water extracts of the leaves, the dry matter, total phenolic substances, and antioxidant activity were determined using three methods: superoxide anion radical scavenging activity, hydroxyl radical scavenging activity, and ferric reducing ability of plasma (FRAP) assay. The highest amount of total phenols was detected in the ethanolic extract of the leaves from the field 911.14 mg GAE L−1, resp. 69.70 mg GAE g−1 DM. The lowest amount was noticed in the leaves from the greenhouse 408.88 mg GAE L−1, resp. 13.07 mg GAE g−1 DM. The amount was significantly lower in the aqueous extracts. A high antioxidant activity of the leaves from the field was detected in all ethanolic and hot water extracts. Both types of leaf extracts from the greenhouse showed statistically significant lower antioxidant activity. The obtained results indicate that outdoor cultivation in a temperate climate zone was stressful for the plants, leading to an increased formation of phenolic substances, and consequently to higher antioxidant activity.

In this study, we analyzed the phytosociological data from four sample sites located in the Pannonian region. The study areas, ranging from 2.4 to 2.5 hectares, have been subjected to goat grazing and mowing for 24 years. N1: Nagyréde, an overgrazed pasture with 24 goats; N2: Nagyréde, a mown field; C1: Csokvaomány, a lightly grazed pasture with 12 goats; and meadow C2: Csokvaomány, a site that is both mown and grazed. Six phytosociological surveys were conducted randomly in each area. We also considered the conservation value, biomass production, and forage values. Phytosociological data were processed using hierarchical cluster analysis and the non-parametric Kruskal–Wallis test. The overgrazed pasture (N1) exhibited the most degraded vegetation community, dominated by weeds and disturbance-tolerant species. The overgrazed (N1) pasture had a low forage value because of the different timing of treatments. Even in the lightly grazed pasture (C1), the proportion of species indicative of degradation was significant. The species composition of the areas indicated that the mown and subsequently grazed area (C2) had outstanding values. The species richness of C2 was twice that of the mown field (N2). Based on the present study, a combination of light grazing pressure and mowing is the most suitable approach for managing and economically utilizing these grasslands. Full article

Our study examined the impact of grazing by Hungarian Grey cattle on plant communities in grasslands restored and established through different methods. The grasslands were established and restored in 2009 using five methods: (I) naturally regenerating fallow, (II) hay-mulch addition, (III) seeded grassland following soil preparation, (IV) grazing on abandoned alfalfa fields, and (V) overseeded fallow initiated in 1989. From 2009 to 2011, all sites were uniformly mowed, after which they were grazed using free-ranging Hungarian Grey cattle starting in 2012. This project aims to restore traditional land use and dry grassland grazing in the region. Phytosociological recordings were conducted in 2012, the first year following grazing initiation, and again in 2020, nine years later. We assessed the botanical composition and grassland management value across sites in a 260-hectare experimental area within the Pannonian biogeographic region. The current study seeks to determine how different grassland restoration techniques have influenced the botanical composition and grassland management values of pastures and to identify the most suitable restoration methods. Statistical analyses were conducted using R to assess species count differences across four vegetation categories. The results indicate that the overseeded fallow established in 1989 and the hay-mulch addition method were the most effective techniques. Directly seeded grasslands and abandoned alfalfa fields differed most significantly from these areas. Across all types, species richness and total cover increased relative to the initial conditions in 2012, and the naturalness of the species composition also improved. Returning to traditional land use improved the ecological state of all sites. Restoration of the grazed areas proved optimal over the elapsed period, with two years of mowing followed by grazing. Grazing with Hungarian Grey cattle, a low-impact rustic breed, yielded successful grassland restoration outcomes. Among the restoration methods, direct seeding and the use of alfalfa fields proved uneconomical and ineffective in promoting the desired species composition. Natural regeneration and, particularly, the hay-mulch addition method, were the most effective for conservation and grassland management. Full article

There are many techniques for the extension and generalization of fractional theories, one of which improves fractional operators by means of their kernels. This paper is devoted to the most general concept of interval-valued functions, studying fractional integral operators for interval-valued functions, along with the multi-variate extension of the Bessel–Maitland function, which acts as kernel. We discuss the behavior of Hermite–Hadamard Fejér (HHF)-type inequalities by using the convex fuzzy interval-valued function (C-FIVF) with generalized fuzzy fractional operators. Also, we obtain some refinements of Hermite–Hadamard(H-H)-type inequalities via convex fuzzy interval-valued functions (C-FIVFs). Our results extend and generalize existing findings from the literature. Full article
