Small reservoirs have important functions, such as water resource guarantee, flood control and drought resistance, biological habitat and maintaining regional economic development. In order to better clarify the impact of agricultural activities on the nutritional status of water bodies in small reservoirs, zooplankton were quantitatively collected from four small reservoirs in the Jiuxianshan agricultural area of Qufu, Shandong Province, in March and October 2023, respectively. The physical and chemical parameters in sampling points were determined simultaneously. Meanwhile, water samples were collected for nutrient salt analysis, and the eutrophication of water bodies in four reservoirs was evaluated using the comprehensive nutrient status index method. The research found that the species richness of zooplankton after farming (100 species) was significantly higher than that before farming (81 species) (p < 0.05). On the contrary, the dominant species of zooplankton after farming (7 species) were significantly fewer than those before farming (11 species). The estimation results of the standing stock of zooplankton indicated that the abundance and biomass of zooplankton after farming (92.72 ind./L, 0.13 mg/L) were significantly higher than those before farming (32.51 ind./L, 0.40 mg/L) (p < 0.05). Community similarity analysis based on zooplankton abundance (ANOSIM) indicated that there were significant differences in zooplankton communities before and after farming (R = 0.329, p = 0.001). The results of multi-dimensional non-metric sorting (NMDS) showed that the communities of zooplankton could be clearly divided into two: pre-farming communities and after farming communities. The Monte Carlo test results are as follows (p < 0.05). Transparency (Trans), pH, permanganate index (COD_Mn), electrical conductivity (Cond) and chlorophyll a (Chl-a) had significant effects on the community structure of zooplankton before farming. Total nitrogen (TN), total phosphorus (TP) and electrical conductivity (Cond) had significant effects on the community structure of zooplankton after farming. The co-linearity network analysis based on zooplankton abundance showed that the zooplankton community before farming was more stable than that after farming. The water evaluation results based on the comprehensive nutritional status index method indicated that the water conditions of the reservoirs before farming were mostly in a mild eutrophic state, while the water conditions of the reservoirs after farming were all in a moderate eutrophic state. The results show that the nutritional status of small reservoirs in agricultural areas is significantly affected by agricultural activities. The zooplankton communities in small reservoirs underwent significant changes driven by alterations in the reservoir water environment and nutritional status. Based on the main results of this study, we suggested that the use of fertilizers and pesticides should be appropriately reduced in future agricultural activities. In order to better protect the water quality and aquatic ecology of the water reservoirs in the agricultural area. Full article

Background: Iron deficiency anemia (IDA) represents a significant public health concern, particularly among female populations. Various demographic factors, including age and socioeconomic status, have a substantial impact on overall health outcomes, contributing to the prevalence of IDA. The primary objective of this study was to assess the knowledge and awareness of iron deficiency anemia among the adult population and to examine its correlation with various sociodemographic factors. Methods: A cross-sectional study was conducted in the Northern Region of Saudi Arabia between October and December 2024. Data were collected using a structured questionnaire from 385 participants aged 18 years and older. The Chi-square test was utilized to assess the association between categorical variables. Results: In this study, 42.5% of participants demonstrated good knowledge of IDA, 48.1% had moderate knowledge, and 9.4% showed poor knowledge. Knowledge levels were significantly associated with gender, age, education, and self-perceived IDA status. Women, older individuals, and those with higher levels of education had a greater knowledge of IDA. Regarding attitude, 93% of participants had a positive attitude, while only 7% exhibited a negative attitude. Interestingly, none of the explanatory variables were significantly linked to attitude, suggesting that positive attitude toward IDA was consistent across all demographic groups. Conclusions: This study highlights the need for targeted health initiatives focusing on diet, supplementation, symptom recognition, and prevention to effectively reduce the burden of IDA. Prioritizing education through symposiums and medical programs in high-prevalence regions is crucial. Full article

In Ukraine, SARS-CoV-2 detection and national genomic surveillance have been complicated by full-scale war, limited resources, and varying levels of public health infrastructure impacted across the country. Following the Spring of 2022, only a paucity of data have been reported describing the prevalence and variant dynamics of SARS-CoV-2 in the country. Comparative whole genome analysis has overtaken diagnostics as the new gold standard for detecting and tracing emerging variants while showing utility to rapidly inform diagnostics, vaccine strategies, and health policy. Herein, we provide an updated report characterizing the dynamics and prevalence of SARS-CoV-2 in Ukraine from 1 May 2022 to 31 March 2024. The present study extends previous reports for disease incidence Waves 1–4 in Ukraine with the addition herein of Waves 5, 6, and 7, occurring from August to November 2022 (Wave 5), February to May 2023 (Wave 6), and October 2023 to January 2024 (Wave 7). During the study period, the national Case Fatality Rate (CFR) fluctuated between 0.46% and 1.74%, indicating a consistent yet modest rate when compared to the global average. The epidemiological dynamics of Variants of Concern (VOCs) in Ukraine reflected global patterns over this period, punctuated by the rise of the BA.5 lineage and its subsequent replacement by the Omicron subvariants XBB and JN.1. Our analysis of variant dispersal patterns revealed multiple potential spatiotemporal introductions into Ukraine from Europe, Asia, and North America. Our results highlight the importance of ongoing genomic surveillance to monitor variant dynamics and support global efforts to control and mitigate COVID-19 disease risks as new variants arise.

Background and Objectives: Excessive social media use is repeatedly linked to negative body image outcomes, yet its association with muscle dysmorphia, especially in athletic youth, remains underexplored. We investigated how social media exposure, comparison behavior, and platform engagement relate to muscle dysmorphia symptomatology in young German athletes. Materials and Methods: An anonymous, web-based cross-sectional survey was conducted (July–October 2024) of 540 individuals (45% female; mean age = 24.6 ± 5.3 years; 79% ≥ 3 h sport/week) recruited via Instagram. The questionnaire comprised demographics, sport type, detailed social media usage metrics, and the validated German Muscle Dysmorphic Disorder Inventory (MDDI-1, 15 items). Correlations (Spearman’s ρ, Kendall’s τ) were calculated; multivariate importance was probed with classification-and-regression trees and CatBoost gradient boosting, interpreted via SHAP values. Results: Median daily social media time was 76 min (IQR 55–110). Participants who spent ≥ 60 min per day on social media showed higher MDDI scores (mean 38 ± 7 vs. 35 ± 6; p = 0.010). The strongest bivariate link emerged between perceived social media-induced body dissatisfaction and felt pressure to attain a specific body composition (Spearman ρ = 0.748, Kendall τ = 0.672, p < 0.001). A CatBoost gradient-boosting model out-performed linear regression in predicting elevated MDDI. The three most influential features (via SHAP values) were daily social media time, frequency of comparison with fitness influencers, and frequency of “likes”-seeking behavior. Conclusions: Intensive social media exposure substantially heightens muscle dysmorphia risk in young German athletes. Machine-learning interpretation corroborates time on social media and influencer comparisons as primary drivers. Interventions should combine social media literacy training with sport-specific psychoeducation to mitigate maladaptive comparison cycles and prevent downstream eating disorder pathology. Longitudinal research is warranted to clarify causal pathways and to test targeted digital media interventions. Full article

Background: Uterine rupture is a rare but severe obstetric complication with significant maternal and neonatal consequences. While partial uterine ruptures (PURs) are generally associated with less severe outcomes, complete uterine ruptures (CURs) carry a higher risk of serious impact on both mother and child. The present study aimed to evaluate outcomes and identify risk factors for each type of rupture, and also to define high- and low-risk uterine ruptures based on clinical outcomes. Methods: A retrospective analysis of 112 uterine rupture cases, including 29 CURs and 83 PURs, was conducted at the Women’s Hospital of the University of Cologne from October 2010 to January 2021. Results: Maternal outcomes revealed that CUR was associated with higher risks of prolonged hospitalization (p = 0.003), postpartum hemorrhage (p < 0.001), maternal transfusion (p = 0.003), and ICU transfer (p = 0.004) compared to PUR. Neonatal outcomes showed a significantly higher risk of severe acidosis (p < 0.001), low APGAR scores (p < 0.001), NICU transfers (p = 0.004), and resuscitation needs (p = 0.016) in CUR cases. Factors increasing the risk of CUR included pathological CTG (OR = 1.9, 95% CI: 0.99–7.14, p = 0.05), abdominal pain (OR = 2.63, 95% CI: 1.10–6.25, p = 0.03), previous vaginal birth (OR = 7.14, 95% CI: 0.025–20, p < 0.001), and no uterine contractions (OR = 7, 95% CI: 1.21–40.56, p = 0.03). A previous cesarean section significantly increased the risk of CUR (OR = 4.94, 95% CI: 1.38–17.67, p = 0.014), whereas more than two cesarean sections reduced the risk (OR = 0.66, 95% CI: 0.13–3.22, p = 0.61). A comparison of CUR with maternal and neonatal high-risk rupture groups revealed that low gestational age and a history of previous cesarean sections were significant risk factors for neonatal high-risk rupture. Conclusion: Vaginal birth and abdominal pain were identified as key risk factors for CUR, which lead to severe maternal and neonatal outcomes. Recognizing these risk factors can help clinicians optimize risk stratification and decision-making, and enhance monitoring strategies to prevent adverse outcomes. Full article

Background: This study aims to reveal the demographic and clinical data of patients receiving TNF-α blockers, to compare the characteristics of those who received latent tuberculosis infection (LTBI) treatment and those who did not, and to evaluate and determine potential risk factors for developing active TB disease. Methods: A systematic retrospective study was conducted in a tertiary university hospital examining all patients receiving at least one TNF-α blocker between January 2019 and October 2024. The incidence of tuberculosis (TB) was analyzed across various TNF-α blocker medications in patients, both with and without LTBI treatment. Results: A total of 519 patients had TNF-α blockers: 452 (87.09%) underwent TST, 193 (37.1%) underwent booster TST, and 33 (6.3%) underwent IGRA/TST; 362 (69.7%) were treated for LTBI, and 7 (1.3%) developed TB. Comparing all TNF-α blockers, adalimumab showed a higher risk of TB. Patients with and without LTBI treatment did not significantly differ in TB incidence after biologic therapy. Conclusions: The incidence of TB in people taking TNF-α blockers was higher compared to the incidence in the general population. LTBI screening, including both TST and IGRA, should be performed with TST and IGRA tests, and LTBI-positive individuals should be started on preventive treatment. However, it should not be forgotten that active TB disease may also develop in LTBI-negative individuals. Full article

Background/Objectives: War conflicts impact public health and patient hospital presentations. We aimed to assess the incidence and severity of acute appendicitis (AA) in children during the 2023 Israeli–Hamas–Hezbollah war. Methods: This multicenter retrospective cohort study included children (<18 years) admitted with AA in six medical centers in a 2-month period during the war (7 October–30 November 2023) and a comparable period in 2022. Demographic, clinical, laboratory, imaging, treatment, and outcome data were collected at individual medical centers and analyzed, with subgroup analysis based on proximity to conflict zones. Statistical tests used were Kolmogorov–Smirnov test, Student’s t-test, Mann–Whitney U, and Pearson chi square. p < 0.05 was considered significant. Results: Among 209 patients (106 in 2023, 103 in 2022), a higher rate of complicated AA during wartime was observed, although not statistically significant (27% vs. 18%, p = 0.11). The median symptom-to-presentation time remained 24 h (p = 0.64). The overall incidence of AA decreased by 20% in medical centers near conflict zones but increased by 28% in centers distant from conflict zones. The proportion of complicated AA doubled during the war in hospitals close to conflict zones as compared to during pre-war time (16% vs. 9%, respectively, p = 0.016), with a trend toward higher C-reactive protein (CRP) levels [26.5 (5.3–107.0) vs. 13 (3.4–40.9), respectively, p = 0.075], although symptom-to-presentation times remained unchanged (24 h in both groups, p = 0.32). Conclusions: Proximity to war zones was associated with an increase in the rate of complicated appendicitis in children. While the causes remain unclear, this finding highlights the complex impact of war on healthcare in general and on the well-being of children in particular. Full article

Background: Musculoskeletal injuries have a substantial impact on athletes, affecting sports performance and increasing the risk of future musculoskeletal disorders (e.g., osteoarthritis). Injury prevention programs are essential to reduce the risk of sport-related injuries and meta-analyses can provide a large amount of information in a single article. Objective: To summarize the pooled effects of injury prevention programs focused on any form of physical exercise in the incidence and risk of musculoskeletal injuries and reinjuries by sports and musculoskeletal body regions. Methods: The CINAHL (via EBSCOhost), Embase (via Elsevier), Epistemonikos, PubMed, Scopus, SPORTDiscus (via EBSCOhost), and the Cochrane Library e-databases were searched from inception to 7 October 2024. Systematic reviews with meta-analyses of randomized clinical trials were considered. The methodological quality of systematic reviews was assessed with AMSTAR 2. The degree of overlap between meta-analyses of interest was calculated. Results: Fourteen systematic reviews were included. Thirteen of these reviews were focused on soccer. Overall, meta-analyses including a specific injury prevention program (FIFA 11+ and FIFA 11+ kids) found that these programs may reduce the risk of musculoskeletal injuries among soccer players. Concretely, FIFA 11+ may reduce the risk of ankle, knee, hip/groin, and hamstring injuries, whereas FIFA 11+ kids may decrease the risk of ankle and knee injuries. Conclusions: FIFA 11+ and FIFA 11+ kids may reduce the risk of sports musculoskeletal injuries, mainly in the lower limbs. However, many clinical and methodological issues (e.g., the lack of meta-analyses in many types of sports) were discussed and highlighted the difficulty of making robust clinical recommendations with the current data.

The use of a rock-bed accumulator for a short-term heat storage and air exchange in a building facility is an economical and energy-efficient technological solution to balance and optimize the energy supplied to the facility. Existing scientific studies have not addressed, as yet, the environmental impacts of using a rock bed for heat storage. The purpose of the research is the environmental life cycle assessment (LCA) of a heat storage system in a rock-bed accumulator supported by a photovoltaic installation. The boundaries of the analyzed system include manufacturing the components of the storage device, land preparation for the construction of the accumulator, the entire construction process, including transportation of materials, and its operation in cooperation with a horticultural facility (foil tunnel) during one growing season, as well as the photovoltaic installation. The functional unit in the analysis is 1 square meter of rock-bed accumulator surface area. SimaPro 8.1 software and Ecoinvent database were used to perform the LCA, applying the ReCiPe model to analyze environmental impact. The analysis showed the largest negative environmental impact occurs during raw materials extraction and component manufacturing (32.38 Pt). The heat stored during one season (April to October) at a greenhouse facility reduces this negative impact by approx. 7%, mainly due to the reduction in the use of fossil fuels to heat the facility. A 3 °C increase in average air temperature results in an average reduction of 0.7% per year in the negative environmental impact of the rock-bed thermal energy storage system. Full article

In the study, a comprehensive investigation on potential bacterial pathogens affecting largemouth bass (Micropterus salmoides) was performed. Monthly surveys were conducted from April to October 2024. Diseased largemouth bass exhibited diverse clinical symptoms, such as rot of gill and fin, ulcers on body surface, and petechial hemorrhages in liver. Following isolation and identification, a total of 21 potential bacterial pathogens (numbered strain 1 to 21, respectively) were identified. The genus Aeromonas had the highest proportion (67.14%), among which the frequency of Aeromonas veronii was 24.60%. TEM analysis revealed that the bacterial strains exhibited three predominant shapes (rod-shaped, spherical, and curved) with length ranging from 0.5 to 3 μm. Flagellar structures were observed in strains 1–4, 6–8, 11–17, and 19–21, with variations in number and growth sites. Three isolates (strains 9, 10, 18) demonstrated Gram-positive characteristic, and strains 5, 11, and 18 have capsule structures. Strains 5, 9, 10, and 18 were non-motile, and strains 1–4, 6, 7, 9–11, 16–18, and 21 exhibited β-hemolysis. Physiological and biochemical characteristics of the 21 bacterial isolates were comprehensively analyzed. Antibiotic sensitivity testing revealed that florfenicol and enrofloxacin exhibited excellent antibacterial effects. These data will enrich the potential bacterial diseases information and promote the healthy development of the largemouth bass industry. Full article

Background and Objectives: The COVID-19 pandemic affected children’s lifestyle, due to strict lockdown restrictions. This study evaluated Romanian children’s lifestyle prior to and during the pandemic and their associated factors. Materials and Methods: A longitudinal study was performed in 7 urban schools from Romania. Data were gathered at baseline (T1), from October to November 2019, and follow-up (T2), from December 2020 to February 2021. Results: A total of 880 children were enrolled at baseline, 484 at T2, and 350 in both evaluations. Initially, 66.3% did not perform at least one hour of physical activity per day, two thirds did not sleep at least 9 h per night during the week, and more than one third used the internet more than 2 h daily. Investigating changes before and during COVID-19 among students participating at both evaluations, a statistically significant drop in physical activity and sleep time during the week was recorded, while weekend sleep and internet use increased. Several gender- and age-related differences were noted. Physical activity and sleep patterns as well as internet use behavior at T1 predicted the same behavior at T2. Reduced sleep during the week and internet overuse were positively associated at both waves as well as longitudinally. Conclusions: These findings highlight calls for combined strategies that include parents, schools, and community, aiming to enhance a healthier lifestyle among children. Full article

The blue crab (Callinectes sapidus) is an invasive alien species in the Mediterranean Sea, posing threats to biodiversity, fisheries, and aquaculture. Climate change has worsened these challenges, influencing the distribution of bacterial species, including Shewanella species, which are sensitive to changes in temperature and salinity. In this study, 300 blue crabs were sampled between June and October 2024 from the Sacca di Goro (Northern Adriatic Sea, Italy) to investigate the prevalence of Shewanella species in their haemolymph. The prevalence was found to be 7% (21/300), with species such as S. mesophila, S. algae, S. cowelliana, and S. baltica identified, particularly in the months of September and October. Molecular techniques, including MALDI-TOF MS and rpoB gene amplification, were used to identify isolates. Antibiotic susceptibility testing (AST) revealed a trend of resistance to beta-lactam antibiotics. A network analysis was also conducted to examine the global trends of Shewanella research in relation to humans, animals, and the marine environment. While proper cooking eliminates the risk to consumers, handling without personal protective equipment can increase exposure, particularly for vulnerable individuals such as those who are elderly or immunocompromised. Mild symptoms are observed in children. Further studies, particularly with a One Health approach, are crucial to better understand the transmission dynamics and evolving antibiotic resistance of Shewanella species. Full article

Introduction: The prevention of heart failure (HF) exacerbation is crucial for patient prognosis, and preventive treatment for potential symptoms and warning signs is essential in this context. The TriageHF © algorithm has been retrospectively validated and has demonstrated good correlation with HF episodes. This study analyzes the effectiveness of the TriageHF © algorithm in routine clinical practice, emphasizing the role of episode duration in its predictive capacity. Materials and methods: From October 2017 to October 2020, all patients who received a Medtronic Amplia DR implant were prospectively selected for analysis. To evaluate the algorithm’s diagnostic capacity, it was compared with the clinical diagnosis of HF episodes during follow-up. Results: The sustained moderate-risk (more than 7 days) and high-risk alerts both showed high positive predictive values (11.25% and 27.27%, respectively), along with an increase in the relative risk of HF, particularly in high-risk alerts (hazard ratio is 46.21 times higher than for sustained moderate-risk alerts). Furthermore, there was higher event-free survival in real low-risk alerts than in both sustained medium-risk and high-risk alerts (p < 0.01). Conclusions: TriageHF © can predict the worsening of patients with ICD CRT. Medium-risk alerts lasting less than 7 days do not pose a greater risk of HF episodes, while high-risk alerts, regardless of their duration, are highly correlated with HF episodes. Full article

This study explores the relationship between land use and land cover (LULC) changes and a significant cyclogenesis event that occurred in Alabama’s Black Belt region from 6 to 7 October 2021. Utilizing the Weather Research and Forecasting (WRF) model, two scenarios were analyzed: the WRF Control Run, which maintained unchanged LULC, and the WRF Sensitivity Experiment, which converted 56.5% of forested areas into cropland to assess the impact on storm dynamics. Quantitative comparisons of predicted rainfall from both simulations were conducted against observed data. The control run demonstrated a Root Mean Square Error (RMSE) of 1.64, indicating accurate rainfall predictions. In contrast, the modified scenario yielded an RMSE of 2.01, suggesting lower reliability. The Mean Bias (MB) values were 1.32 for the control run and 1.58 for the modified scenario, revealing notable discrepancies in accuracy. The coefficient of determination (R²) was 0.247 for the control run and 0.270 for the modified scenario. The Nash–Sutcliffe Efficiency (NSE) value was 0.1567 for the control run but dropped to −0.2257 following LULC modifications. Sensitivity analyses revealed a 60% increase in heat flux and a 36% rise in precipitation, underscoring the significant impact of LULC on meteorological outcomes. While this study concentrated on the Black Belt region, the methodologies employed could apply to various other areas, though caution is advised when generalizing these results to different climates and socio-economic contexts. Further research is necessary to enhance the model’s applicability across diverse environments. Full article

Background/Objectives: Poor sleep quality is a prevalent health concern among older adults, impacting cognitive and physical functions. This study aimed to determine the association between sleep quality and self-reported health status among middle-aged and older adults in northern Taiwan. Methods: This cross-sectional study, conducted from April to October 2017, assessed participants using the Chinese version of the Pittsburgh Sleep Quality Index (CPSQI) with a cut-off of 5; scores above 5 indicated poor sleep quality. The self-reported health status was evaluated using a questionnaire. Statistical analyses included the chi-squared test, one-way ANOVA, Cochran–Armitage trend test, and multiple logistic regression models. Results: This study included 850 adults (243 males and 607 females). The participants were grouped according to their self-reported health status as follows: good (n = 278), fair (n = 499), and poor (n = 73). Poor health status was associated with worse sleep quality components, including sleep latency, efficiency, disturbances, medication use, and daytime dysfunction (p for trend < 0.001). The multiple logistic regression analysis showed higher dissatisfaction with health status among the participants with a CPSQI score of >5 (odds ratio, 4.12; 95% CI 2.26–7.50; p < 0.001). A poor health status was reported by 19.51% of the participants sleeping < 5 h, compared to 6.97% of the participants sleeping 5–6 h, 6.60% of the participants sleeping 6–7 h, and 6.34% of the participants sleeping > 7 h, showing a trend toward a shorter sleep duration (p for trend = 0.002). Conclusions: Our study findings indicate that a poor sleep quality and short sleep duration were independent risk factors for poor self-reported health status in middle-aged and older adults in Taiwan. Addressing sleep quality is crucial for implementing preventive health measures in this demographic group. Full article
