Evaluating athletes' sports skills is significant for optimizing their training strategies and improving competitive outcomes. Although various studies are done to assess athletes' skills, they face challenges because of their limitations in capturing the complex, intricate patterns in athletes' movements. Hence, we proposed an innovative approach utilizing trajectory analysis and machine learning algorithms to evaluate and optimize athletes' sports skills. Initially, the trajectory data is collected using advanced motion tracking technology during either training or competitive sessions of the athletes. The collected data was pre-processed, and then feature extraction was performed to extract the most important and relevant features within the data. Further, the Gradient Boosting Decision Tree (GBDT) was trained using the extracted features to predict the athletes' performances. The GBDT is a powerful machine learning algorithm that can handle complex, non-linear interconnections among variables, enabling it to accurately predict the athletes' performances. Finally, we applied the Whale Optimization Algorithm (WOA) to refine the training process of the GBDT, enabling precise training and accurate predictions. The proposed methodology was implemented in the MATLAB software, and it is validated using the real-world athlete data collected during training sessions. The experimental results are validated in terms of parameters such as accuracy, precision, recall, and f-measure. Furthermore, we made a comparative study with the existing methods to validate the effectiveness and robustness of the proposed technique.

Background Strokes significantly impair quality of life and incur high economic and societal burdens. The triglyceride and glucose (TyG) index is a biochemical marker of insulin resistance (IR) and may have important value in the prediction of strokes, especially ischemic stroke (IS). Our study aims to investigate the relationship between TyG index and IS and ascertain whether TyG index is independently associated with IS adverse outcomes. Methods The Cochrane, Embase, Medline, Web of Science, PubMed, and other relevant English databases and related websites were systematically searched for articles on ‘‘TyG index’’ and \"stroke\" published from inception to April 4, 2022. We reviewed the available literature on the TyG index and its relation to predicting IS occurrence in the general population and adverse clinical outcomes. We calculated odds ratios (OR) of TyG index and its predictability of IS occurrence and adverse outcomes. Statistical analyses were performed using the Meta Package in STATA, version 12.0. Results A total of 18 studies and 592,635 patients were included in our analysis. The pooled effect values of all stroke types showed that higher TyG index was associated with increased the risk of IS in the general population (OR 1.37; 95% CI 1.22–1.54) in a total sample of 554,334 cases with a high level of heterogeneity (P = 0.000, I 2  = 74.10%). In addition, compared to IS patients with a lower TyG index, IS patients with a higher TyG index was associated with higher risk of stroke recurrence (OR: 1.50; 95% CI 1.19–1.89) and increased risk of mortality (OR 1.40 95% CI 1.14–1.71). No correlation was found in the effect value combinations of poor functional outcomes (OR 1.12; 95% CI 0.88–1.43) and neurological worsening (OR: 1.76; 95% CI 0.79–3.95) in a total sample of 38,301 cases with a high level of heterogeneity (P = 0.000; I 2  = 77.20%). Conclusions TyG index has potential value in optimizing risk stratification for IS in the general population. Furthermore, there is a significant association between high TyG index and many adverse outcomes of stroke, especially stroke recurrence and high mortality. Future studies should focus on multi-center and multi-regional designs in order to further explore the relationship between IS and TyG index.

The relationship between foraging modes and sensory system morphology is critical for understanding the ecological and evolutionary adaptations of lizards. This study investigates the nasal olfactory system (NOS) and vomeronasal system (VNS) of four sympatric lizards from the Turpan Basin, China, which exhibit distinct foraging strategies: the active foraging Eremias roborowskii (Lacertidae), the sit‐and‐wait foraging Phrynocephalus axillaris (Agamidae) and Tenuidactylus dadunensis (Gekkonidae), and the seasonally frugivorous Teratoscincus roborowskii (Sphaerodactylidae), which adopts active foraging during fruit‐searching. Using diffusible iodine‐based contrast‐enhanced computed tomography (DiceCT) and histological sections, we compared the morphology and histology of their NOS and VNS. The results showed significant differences in the nasal cavity and vomeronasal organ structures: active foraging species (E. roborowskii and T. roborowskii) exhibited an enlarged nasal cavity with well‐developed lateral nasal conchae, thicker olfactory epithelium (OE), and higher densities of olfactory receptor cells compared to sit‐and‐wait foraging species. The VNS of active foraging lizards also showed thicker vomeronasal sensory epithelium (VSE) and greater vomeronasal receptor cell densities, particularly in E. roborowskii. In contrast, sit‐and‐wait foraging P. axillaris displayed reduced nasal conchae, thinner OE and VSE, and fewer receptor cells. Interestingly, the seasonal active foraging T. roborowskii demonstrated NOS enhancements akin to obligate active foraging species, suggesting a link between fruit detection and olfactory specialization. These findings support the hypothesis that foraging modes drive morphological divergence in the olfactory systems of lizards, highlighting the role of sensory adaptations in ecological niche specialization. This study provides novel insights into the coevolution of sensory structures and foraging behavior in sympatric lizards. Further studies are needed to explore the functional implications of these morphological differences.

Sarcopenia is a progressive skeletal muscle disorder involving the loss of muscle mass and function, associated with an increased risk of disability and frailty. Though its prevalence in dementia has been studied, its occurrence in mild cognitive impairment (MCI) has not been well established. As MCI is often a prelude to dementia, our study aims to investigate the prevalence of MCI among individuals with sarcopenia and to also ascertain whether sarcopenia is independently associated with MCI. The Cochrane Library, PubMed, Ovid, Embase and Web of Science were systematically searched for articles on MCI and/or sarcopenia published from inception to 1 February 2022. We reviewed the available literature on the number of individuals with MCI and/or sarcopenia and calculated odds ratios (ORs) of sarcopenia in MCI and MCI in sarcopenia, respectively. Statistical analyses were performed using the meta package in Stata, Version 12.0. A total of 13 studies and 27 428 patients were included in our analysis. The pooled prevalence of MCI in participants with sarcopenia was 20.5% (95% confidence interval [CI]: 0.140–0.269) in a total sample of 2923 cases with a high level of heterogeneity (P < 0.001; I2 = 95.4%). The overall prevalence of sarcopenia with MCI was 9.1% (95% CI: 0.047–0.134, P < 0.001; I2 = 93.0%). For overall ORs, there were 23 364 subjects with a mean age of 73 years; the overall adjusted OR between MCI and sarcopenia was 1.46 (95% CI: 1.31–1.62). Slight heterogeneity in both adjusted ORs (P = 0.46; I2 = 0%) was noted across the studies. The prevalence of MCI is relatively high in patients with sarcopenia, and sarcopenia may be a risk factor for MCI.

The artificial grammar learning paradigm is a classic method of investigating the influence of universal constraints on shaping learning biases on language acquisition. While this method has been used extensively by linguists to test theoretical claims in generative grammar, one of the most prevalent frameworks in language acquisition, several studies have questioned whether artificial grammar learning reflects language acquisition enough to allow us to use it to draw inferences about the validity of universal constraints, particularly those arising from phonetic naturalness. The current study tests whether artificial grammar learning shows the effect of one robust phonetic naturalness constraint: the restriction on nasal harmony patterns arising from the sonority hierarchy. Nasal harmony is of particular interest because it is one of the few types of harmony that occurs between consonants and vowels, which is an under-researched topic. The results, contrary to the skeptical concerns, showed that participants (n = 120) could learn an artificial grammar involving a natural pattern, but could not learn one corresponding to an arbitrary/phonetically unmotivated pattern in the same way or to the same degree. This study contributes epistemic support to the large body of work using artificial grammar experiments to test phonological operations.

Background Necrotizing soft tissue infections (NSTI) are rapidly progressing and life-threatening conditions that require prompt diagnosis. However, differentiating NSTI from other non-necrotizing skin and soft tissue infections (SSTIs) remains challenging. We aimed to evaluate the diagnostic value of the biochemical analysis of soft tissue infectious fluid in distinguishing NSTIs from non-necrotizing SSTIs. Methods This cohort study prospectively enrolled adult patients between May 2023 and April 2024, and retrospectively included patients from April 2019 to April 2023. Patients with a clinical suspicion of NSTI in the limbs who underwent successful ultrasound-guided aspiration to obtain soft tissue infectious fluid for biochemical analysis were evaluated and classified into the NSTI and non-necrotizing SSTI groups based on their final discharge diagnosis. Common extravascular body fluid (EBF) criteria were applied. Results Of the 72 patients who met the inclusion criteria, 10 patients with abscesses identified via ultrasound-guided aspiration were excluded. Based on discharge diagnoses, 39 and 23 patients were classified into the NSTI and non-necrotizing SSTI groups, respectively. Biochemical analysis revealed significantly higher albumin, lactate, lactate dehydrogenase (LDH), and total protein levels in the NSTI group than in the non-necrotizing SSTI group, and the NSTI group had significantly lower glucose levels and pH in soft tissue fluids. In the biochemical analysis, LDH demonstrated outstanding discrimination (area under the curve (AUC) = 0.955; p  < 0.001) among the biochemical markers. Albumin (AUC = 0.884; p  < 0.001), lactate (AUC = 0.891; p  < 0.001), and total protein (AUC = 0.883; p  < 0.001) levels also showed excellent discrimination. Glucose level (AUC = 0.774; p  < 0.001) and pH (AUC = 0.780; p  < 0.001) showed acceptable discrimination. When the EBF criteria were evaluated, the total scores of Light’s criteria (AUC = 0.925; p  < 0.001), fluid-to-serum LDH ratio (AUC = 0.929; p  < 0.001), and fluid-to-serum total protein ratio (AUC = 0.927; p  < 0.001) demonstrated outstanding discrimination. Conclusion Biochemical analysis and EBF criteria demonstrated diagnostic performances ranging from acceptable to outstanding for NSTI when analyzing soft tissue infectious fluid. These findings provide valuable diagnostic insights into the recognition of NSTI. Further research is required to validate these findings.

Green nephrology has emerged as a crucial strategy to address the health care sector’s role in the climate crisis, particularly due to the high carbon intensity of dialysis-related services. Aligned with global net-zero commitments, sustainable kidney care can reduce environmental impact while maintaining high standards of patient care. This viewpoint paper proposes a net-zero carbon emissions kidney care center model to address global climate change challenges and advance health care sustainability goals. Based on the United Nations Sustainable Development Goals, we developed a 4D framework: digital transformation, low-carbon health care, circular economy, and preventive medicine. The digital transformation dimension features a precision kidney health system integrating acute and chronic kidney injury digital care models. The low-carbon health care dimension focuses on increasing the rates of kidney transplantation and choosing optimal dialysis modality. The circular economy dimension involves dialysis wastewater recycling, repurposing of medical materials, and integration of renewable energy into facility operations. The preventive medicine dimension incorporates telehealth education, behavioral interventions, and health inequality improvements. This net-zero carbon emissions kidney care model represents an environmental, social, and governance approach to ensuring implementation and continual improvement. It also provides actionable steps for implementing sustainable kidney care and serves as a reference model for net-zero emissions health care systems.

The application of tumor immunotherapy to glioblastoma (GBM) is limited by an unprecedented degree of immune suppression due to factors that include high numbers of immune suppressive myeloid cells, the blood brain barrier, and T cell sequestration to the bone marrow. We previously identified an increase in immune suppressive myeloid-derived suppressor cells (MDSCs) in GBM patients, which correlated with poor prognosis and was dependent on macrophage migration inhibitory factor (MIF). Here we examine the MIF signaling axis in detail in murine MDSC models, GBM-educated MDSCs and human GBM. We found that the monocytic subset of MDSCs (M-MDSCs) expressed high levels of the MIF cognate receptor CD74 and was localized in the tumor microenvironment. In contrast, granulocytic MDSCs (G-MDSCs) expressed high levels of the MIF non-cognate receptor CXCR2 and showed minimal accumulation in the tumor microenvironment. Furthermore, targeting M-MDSCs with Ibudilast, a brain penetrant MIF-CD74 interaction inhibitor, reduced MDSC function and enhanced CD8 T cell activity in the tumor microenvironment. These findings demonstrate the MDSC subsets differentially express MIF receptors and may be leveraged for specific MDSC targeting.

CD74 is a cell-surface receptor for the cytokine macrophage migration inhibitory factor (MIF). MIF binding to CD74 induces a signaling cascade resulting in the release of its cytosolic intracellular domain (CD74-ICD), which regulates transcription in naïve B and chronic lymphocytic leukemia (CLL) cells. In the current study, we investigated the role of CD74 in the regulation of the immunosuppressive tumor microenvironment (TME) in triple-negative breast cancer (TNBC). TNBC is the most aggressive breast cancer subtype and is characterized by massive infiltration of immune cells to the tumor microenvironment, making this tumor a good candidate for immunotherapy. The tumor and immune cells in TNBC express high levels of CD74; however, the function of this receptor in the tumor environment has not been extensively characterized. Regulatory B cells (Bregs) and tolerogenic dendritic cells (tol-DCs) were previously shown to attenuate the antitumor immune response in TNBC. Here, we demonstrate that CD74 enhances tumor growth by inducing the expansion of tumor-infiltrating tol-DCs and Bregs. Utilizing CD74-KO mice, Cre-flox mice lacking CD74 in CD23 + mature B cells, mice lacking CD74 in the CD11c + population, and a CD74 inhibitor (DRQ), we elucidate the mechanism by which CD74 inhibits antitumor immunity. MIF secreted from the tumor cells activates CD74 expressed on DCs. This activation induces the binding of CD74-ICD to the SP1 promotor, resulting in the up-regulation of SP1 expression. SP1 binds the IL-1β promotor, leading to the down-regulation of its transcription. The reduced levels of IL-1β lead to decreased antitumor activity by allowing expansion of the tol-DC, which induces the expansion of the Breg population, supporting the cross-talk between these 2 populations. Taken together, these results suggest that CD74 + CD11c + DCs are the dominant cell type involved in the regulation of TNBC progression. These findings indicate that CD74 might serve as a novel therapeutic target in TNBC.

Background: Branch atheromatous disease (BAD) is a subtype of ischemic stroke associated with early neurological deterioration (END) and poor outcomes. Although BAD shares features with large artery atherosclerosis, optimal treatment strategies remain undefined. Objectives: To assess the efficacy and safety of early dual antiplatelet therapy (DAPT) and high-intensity statins in reducing END and improving outcomes in BAD. Design: A prospective, single-arm study with a historical control group. Methods: This study reports the results of the Statin and Dual Antiplatelet Therapy in Preventing Early Neurological Deterioration in Branch Atheromatous Disease trial. Patients with BAD-related ischemic stroke were treated with aspirin, clopidogrel, and high-intensity statins within 24 h of symptom onset. Outcomes were compared with a historical control cohort treated with single antiplatelet therapy and moderate- or low-intensity statins. The primary outcome was the composite of END (defined as an National Institutes of Health Stroke Scale score increase ⩾2 points within 7 days) or recurrent stroke within 30 days. Secondary outcomes included severe END, functional outcomes at 90 days, and safety events. Results: A total of 91 patients received intensive therapy and 285 received standard treatment. The primary endpoint occurred less frequently in the intensive group (34.1% vs 48.1%; adjusted risk ratio (aRR), 0.71; 95% confidence interval (CI), 0.52–0.98; p = 0.034). Intensive therapy significantly reduced END at 7 days (34.1% vs 47.0%; aRR, 0.73; 95% CI, 0.54–1.00; p = 0.049) but not recurrent stroke at 30 days (2.2% vs 1.8%; aRR, 1.16; 95% CI, 0.25–5.43). Good outcomes at 90 days (modified Rankin Scale ⩽2) were more common with intensive therapy (73.6% vs 57.2%; aRR, 1.27; 95% CI, 1.09–1.48; p = 0.002). Major bleeding and mortality did not differ between groups. Conclusion: Early intensive therapy with DAPT and high-intensity statins significantly reduced END and improved recovery in BAD without compromising safety. Further studies are warranted to validate these findings. Trial registration: ClinicalTrials.gov; Identifier: NCT04824911 (https://clinicaltrials.gov/study/NCT04824911). Plain language summary Early treatment with statin and dual antiplatelet therapy may help prevent worsening stroke symptoms in a specific type of acute ischemic stroke Some people who experience a certain type of acute ischemic stroke called branch atheromatous disease (BAD) may get worse within the first few days, even after receiving medical care. This early worsening can lead to more severe disability. In this study, we tested whether starting a combination of dual antiplatelet therapy—aspirin and clopidogrel—along with a high-dose statin (a cholesterol-lowering medication) within 24 hours of stroke onset could help prevent this early decline. We treated 91 patients with this intensive therapy and compared their outcomes to 285 patients from previous years who had received standard treatment. We found that those who received the early intensive therapy were less likely to experience worsening stroke symptoms during the first week and more likely to have better recovery after three months. The treatment did not increase the risk of serious side effects, although mild bleeding occurred slightly more often. These findings suggest that early use of dual antiplatelet therapy and a strong statin may help improve outcomes in people with this specific kind of stroke. More research is needed to confirm these results and guide future treatment recommendations.
