Harmful Algal Blooms (HABs) pose a significant threat to freshwater ecosystems and public health globally, necessitating reliable early warning systems for effective water resource management. This study presents an end-to-end AI framework designed to predict 4-level ordinal algal alerts in South Korea by systematically integrating heterogeneous spatio-temporal environmental datasets, including GIS-based spatial features, water quality, meteorological, and hydrological data. Our methodological approach involves: (1) extracting spatial features via GIS; (2) optimizing time-lags and interpolating time-series data based on Spearman correlation; and (3) performing ordinal classification using a LightGBM (LGBM) model. To address the ordinal nature of algal alerts, the model was optimized using Optuna with the Quadratic Weighted Kappa (QWK) metric. A rigorous Dual Cross-Validation (CV) framework was employed to assess generalization capabilities: Year-over-Year (YoY) CV with an Embargo technique was used to evaluate temporal performance while preventing data leakage, and Leave-One-Station-Out (LOSO) CV was applied to validate spatial generalization for unobserved locations. Additionally, Isotonic Regression was implemented for probability calibration to enhance the reliability of the predicted outputs. By effectively controlling spatio-temporal information leakage, this study demonstrates superior predictive performance across unobserved timeframes and locations, providing a robust decision-support tool for practical water quality management.

Introduction:Pelvic fractures are severe injuries that can drastically affect a woman's quality of life through sexual dysfunction (SD), genitourinary dysfunction (GD), and increasing the potential need for future cesarean section (C-section). Limited research has captured long-term outcomes after pelvic fractures in women of childbearing age. This study aimed to determine the association between pelvic fractures and rates of C-section, SD, and GD.Methods:All women of childbearing age who sustained a pelvic fracture were identified in a national insurance database. A comparison group of patients with lower extremity long-bone fractures was selected. Patients who gave birth after injury were additionally identified. A minimum of 5 years of follow-up was required for inclusion. Rates of C-section, SD, and GD were compared between cohorts. Multivariate logistic regression analysis was conducted with the inclusion of diabetes, tobacco, hypertension, obesity, and advanced maternal age.Results:A total of 6,174 patients with pelvic fracture and 27,154 control fracture patients were identified. 434 patients with pelvic fracture (7.0%) and 1,258 control fracture patients (4.6%) gave birth after fracture. Patients with pelvic fracture had a significantly higher rate of C-section (50.0% versus 38.8%, P < 0.001), SD diagnosis (10.9% versus 8.8%, P < 0.001), and urinary retention diagnosis (3.5% versus 2.8%, P < 0.001). No significant difference in global GD diagnosis was identified. Multivariate analyses showed that pelvic fracture was associated with C-section (odds ratio [OR]: 1.78; 95% confidence interval [95% CI]: 1.42 to 2.23, P < 0.001), SD diagnosis (OR: 1.23; 95% CI: 1.12 to 1.35, P < 0.001), and urinary retention diagnosis (OR: 1.35; 95% CI: 1.15 to 1.57, P < 0.001).Discussion:Pelvic fractures confer an intrinsic level of risk of C-section, SD, and urinary retention that is elevated beyond what would be expected from a traumatic lower extremity injury alone. Treating orthopaedic surgeons should actively counsel women regarding increased risks, openly discuss postinjury sequelae, and coordinate interspecialty care beyond initial treatment of acute trauma.

To compare the therapeutic effects between needle knife therapy combined with rotation traction manipulation and rotation traction manipulation for the treatment of cervical spondylotic radiculopathy. From November 2013 to June 2015, 80 patients with cervical spondylotic radiculopathy meeting the inclusion criteria were divided into two groups randomly:the control group in which 39 patients were treated with rotation traction manipulation, and the treatment group in which 41 patients were treated with needle knife combined with rotation traction manipulation. The patients in the control group were treated once dayly for 2 weeks, which was 1 course. The patients in the treatment group were treated with needle knife firstly once a week for 2 weeks, which was 1 course;then were treated with the same methods as the patients in the control group. The symptoms, signs score and the therapeutic effects of the two groups before and after treatment were observed. After treatment, symptoms and signs scores declined in both groups(P<0.05). The results of the treatment group were better than effects in the control group(P<0.05). In the treatment group, 19 patients got an excellent result, 16 good, 5 fair and 1 bad;while in the control group, 10 patients got an excellent result, 10 good, 16 fair and 3 bad;the results of the treatment group were better than the results of the control group(P<0.01). Needle knife combined with rotation traction manipulation is an effective method for the treatment of cervical spondylotic radiculopathy, which is better than using manipulation method simply. Needle knife therapy has follow advantages:improving local blood circulation, reducing local content of pain substance, increasing production of substances resisting pain, opening channels and collaterals, and make body reaching new static and dynamic balance on the new foundation.

Medium thickness plates resting on a periodic Winkler’s foundation are investigated. New averaged non-asymptotic models for those plates are proposed. These models are based on the tolerance averaging technique. The main feature of these models is that they describe the effect of period lengths on the overall behaviour of the plate. It is also shown that from governing equations of these models, equations of simplified averaged models (called asymptotic models) can be obtained. An additional interesting feature of the proposed models is that the equations describe also the effect of normal stress in the thickness direction.

The attempt to make a comparative study of Lviv and Łódź in search of certain regularities seems at the first glimpse rather farfetched, because apparently there are rather few analogies between the city of Lviv with its long history and multifunctional tradition and the monofunctional, rather young, industrial city of Łódź. But deeper analysis shows that despite many differences in the course of the history of both cities, some common tendencies can be traced, such as dynamic demographic and spatial development in the second half of the 19th century based on introduction of railway transport, the building of socio-economic and spatial structures of these cities by multi-cultural local communities, and going through half-a-century period of centralized socialist economy after the Second World War. Lviv and Łódź regained political independence almost at the same time (1989 in Poland and 1991 in Ukraine) and entered the route of democratic development, undergoing political and socio-economic transformations during the last 20 years. As a result of these processes as well as the influence of globalization, today we can observe in Łódź and in Lviv similar problems and phenomena, influencing their spatial development and functional restructuring.

We read the article by Lindsey et al.1 with interest, where the authors refer to our findings on the same subject.2 They repeated our experiments and concluded with a different interpretation that staining with anti-Nogo A Ab in CSF of patients with multiple sclerosis (MS) is nonspecific. In reviewing their and our data, we believe that our interpretation is correct. First, we abolished anti-Nogo A staining with preabsorption of anti-Nogo A Ab with a specific Nogo A blocking peptide (sc-11032P). We believe that this is the most reliable criterion for proving that binding of an antibody is specific. In addition, Lindsey et al. found nonspecific staining with a very high concentration (1:5,000) of secondary antibody. We used a lower concentration of secondary Ab (1:20,000), showing no staining of CSF gels not exposed to anti-Nogo A Ab. Specificity of antibody staining is determined by antibody concentration and nonspecific binding is common with higher concentrations, a known phenomenon in antibody binding assays. We are …

Recurrent aphthous ulcers (RAU) is a chronic inflammatory disease with evidence of inappropriate immune response. This study presents the status of innate immune system in RAU. Twenty RAU patients and 19 healthy individuals were selected. The status of peripheral blood neutrophils (reactive oxygen intermediates (ROI) production, CD11b, TNF-RI and TNF-RII expression), concentration of antioxidants, sTNF-R, C3c, C4 and haemolytic activity of the complement system, as well as mannose-binding lectin (MBL), in the serum of RAU patients in active stage and in remission of the disease were determined. Peripheral blood neutrophils were primed in RAU, which resulted in increased ROI production by resting and fMLP-stimulated neutrophils and diminished ROI production after in vitro priming. The increased expression of CD11b on resting and fMLP-stimulated neutrophils in RAU may also point to their previous in vivo stimulation. The decreased total antioxidant status of serum observed in RAU may be a result of increased ROI production by peripheral blood neutrophils. The levels of C3c, C4 and haemolytic activity of the complement system were higher in RAU than in healthy people. No significant differences between active and remission RAU were noted. Presented observations confirm that the innate immune system is involved in RAU pathogenesis.
