Clinical Validation of DNA Methylation Detection in Cervical Exfoliated Cells for Endometrial Cancer in Women with Suspected Lesions
No full textBackground/Objectives: Currently, no non-invasive detection method for endometrial cancer (EC) is recommended in clinical practice worldwide. This study aimed to evaluate the clinical value of detecting DNA methylation of CDO1 and CELF4 (CDO1m/CELF4m) in exfoliated cervical cells for the detection of EC in women with suspected endometrial lesions. Methods: A total of 2164 patients scheduled for hysteroscopic surgery due to suspected endometrial lesions at the Obstetrics and Gynecology Hospital of Fudan University between July 2023 and May 2024 were prospectively enrolled. Preoperative exfoliated cervical cells were collected for dual-gene methylation testing. Clinical data and endometrial thickness measured by transvaginal sonography (TVS) were recorded. Hysteroscopic histopathological diagnosis served as the gold standard to evaluate the performance of methylation testing alone and in combination with TVS. Results: This study included 2164 patients, comprising 33 EC cases, 31 cases of endometrial intraepithelial neoplasia (EIN), and 2100 cases of non-endometrial lesions, with mean ages of 51.7 ± 6.4, 49.5 ± 8.9, and 44.7 ± 9.8 years, respectively (p < 0.001). For EC detection, CDO1m/CELF4m positivity showed a sensitivity of 93.94% (95% CI: 79.77–99.26%), specificity of 96.7% (95% CI: 95.92–97.47%), positive predictive value (PPV) of 31.0% (95% CI: 25.96–36.53%), and negative predictive value (NPV) of 99.90% (95% CI: 99.63–99.98%). For EIN detection, the sensitivity was 83.87%, specificity 97.95%, PPV 37.68%, and NPV 99.76%. Combining TVS with DNA methylation detection further improved the sensitivity and NPV for both EC and EIN detection. Conclusions: DNA methylation detection in exfoliated cervical cells demonstrates high sensitivity and specificity for EC detection. The combination with TVS further enhances sensitivity and NPV, offering a simple and non-invasive triage strategy for patients with suspected endometrial lesions. This study was registered in China Clinical Trial Registry (ChiCTR2200055991) on 30 January 2023

3D Correspondence Between Maxillary Central Incisor Morphology and Facial Shape in Young Adults
No full textBackround: This cross-sectional study aimed to quantify the proportion of 3D tooth–face superimposition in young adults and examine age- and gender-related differences. Methods: In 98 dental students, intraoral MCI and facial scans were acquired under standardized protocols, processed in Mesh Mixer v. 3.5.474and Blender v. 4.3.2., and aligned to reference planes for superimposition. Residual tooth volume, reflecting tooth–face correspondence, was computed via Boolean subtraction. Statistical analyses were performed in IBM SPSS Statistics 25 at α = 0.05. Results: Total tooth volume (1,626,120.79 ± 210,659.56 × 103) exceeded the superimposed volume by 285,052.34 × 103 (17.53%; 95% CI: 15.84–19.22%; p < 0.001), giving a superimposition proportion of 82.6%. Positive correlations between total and remaining tooth volumes were observed overall (ρ = 0.448; p < 0.001), in females (ρ = 0.515; p < 0.001), and in participants < 21 years (ρ = 0.662; p < 0.001). Men had higher total tooth volume than women (1,706,232 ± 151,086 vs. 1,583,561 ± 225,978; p = 0.005). Conclusions: Volumetric analysis revealed high but incomplete dentofacial correspondence. Larger tooth volumes were associated with greater incongruence in females and younger participants, confirming volumetric size as a determinant of morphological congruence. Results highlight clinically meaningful superimposition, supporting the MCI as a reliable reference for restorative planning and esthetic reconstructions, and emphasize the value of 3D analysis for precise dentofacial evaluation and individualized esthetic planning
Theobroma spp. Mucilage as a Valuable Natural Ingredient: Composition, Potential for Food Innovation, and Future Perspectives
No full textPeru is currently distinguished by its remarkable biodiversity, which is characterized by a high level of endemism and a wide array of ecological niches. In the context of biodiversity, the genus Theobroma spp. is particularly noteworthy, encompassing the species Theobroma cacao, Theobroma grandiflorum and Theobroma bicolor, which are collectively referred to as cacao, cupuaçu, and macambo, respectively. The primary economic value of these species is derived from their mucilage-rich pulp and beans. In recent years, the mucilage of the genus Theobroma has gained economic relevance due to its flavor, floral and fruity aroma. The present review article aims to provide a comprehensive exploration of Theobroma spp. mucilage, addressing its characterization and potential applications. The present study investigates aspects related to its origin, cob morphology, proximal composition, bioactive compounds, volatile profile and its application in the food industry. The study highlights a high content of polysaccharides such as reducing sugars, organic acids, pectin, cellulose, hemicellulose, antioxidant capacity, presence of polyphenols and methylxanthines. Through this comprehensive review, a prospective vision is proposed on the opportunities for innovation and sustainable development around the Theobroma mucilage industry, highlighting its relevance not only as a agri-food byproduct, but also as a valuable resource in the productive circular economy and the sustainability of biodiversity
Alert for Imported Malaria in Non-Endemic Areas: A Case Report of Atypical Falciparum Malaria in a Young Child and Diagnostic Experience
No full textBackground: Although China has eliminated indigenous malaria, imported cases, particularly among young and middle-aged workers returning from Africa, constitute a major challenge for current epidemic prevention and control. In contrast, imported malaria in children is extremely rare and often subject to diagnostic delays in non-endemic areas due to atypical clinical presentations. Case presentation: We report a case of a 2-year-11-month-old boy who returned from Sudan, a malaria-endemic region, presenting with fever and diarrhea as the initial symptoms. The case was identified by the laboratory through the blood routine re-examination rules, crucially informed by the patient’s epidemiological history. The diagnosis was ultimately confirmed as Plasmodium falciparum malaria by rapid diagnostic testing and microscopic examination. Conclusion: This diagnostic pathway exemplifies a closed-loop model of “clinical suspicion → targeted laboratory testing → definitive pathogen identification.” It provides a practical framework for the early detection and diagnosis of pediatric imported malaria with atypical presentations in non-endemic areas
Root–Canopy Coordination Drives High Yield and Nitrogen Use Efficiency in Dryland Winter Wheat
No full textImproving yield and nitrogen-use efficiency (NUE) is essential for dryland winter wheat. We hypothesized that cultivars classified as high-yield and high-efficiency (HH) achieve superior performance through coordinated root–canopy traits that enhance water and nitrogen acquisition, sustain post-anthesis photosynthesis, and maintain assimilate and nitrogen remobilization. A two-year field experiment was conducted using ten regionally representative cultivars, which were grouped into HH, high-yield and low-efficiency (HL), low-yield and high-efficiency (LH), and low-yield and low-efficiency (LL) types based strictly on grain yield and NUE. Measurements included yield components, grain-filling, dry matter accumulation and partitioning, soil water use, nitrogen uptake and remobilization, and root–canopy structural traits. HH increased yield by 41.5% and water-use efficiency by 24.1% relative to LH, supported by denser shallow roots, moderate deeper-root development, higher leaf area index, and more compact canopies. HH also exhibited stronger post-anthesis dry matter and nitrogen translocation, resulting in a larger grain number per unit area and improved sink capacity. Correlation analyses further demonstrated positive associations among root–canopy traits, water and nitrogen dynamics, and yield formation. These results support the hypothesis that a coordinated root–canopy structure underlies the superior yield and NUE performance of HH cultivars in dryland systems, providing a physiological basis for cultivar improvement
Exploring the Gut Microbiome in Combat Sports: A Systematic Scoping Review
No full textThe gut microbiota represents a complex microbial ecosystem with the potential to influence athletic performance, energy metabolism, inflammatory responses, and recovery capacity in athletes. However, the specific relationship between microbiota and performance in combat sport athletes remains poorly characterized. This scoping review systematically maps current evidence on gut microbiota-combat sports performance relationships, identifies microbial response patterns to training and competition, evaluates nutritional prebiotic and probiotic interventions, and highlights methodological gaps to guide future research. Following the PRISMA-ScR framework, 8 studies were identified, which included 247 elite and high-level athletes, comprising 169 males and 78 females, with sample sizes ranging from 12 to 53 across wrestling, mixed martial arts, martial arts, judo, and taekwondo. Associations were observed between gut microbiota characteristics and training intensity, competition level, weight management, and pre-competition psychological states. Limited taxonomic consistency was observed across studies, with most bacterial genera appearing in a single investigation, precluding the identification of robust sport-specific microbial signatures. Preliminary trials demonstrated improvements in gastrointestinal symptoms, aerobic performance, and psychological fatigue with prebiotic and probiotic interventions. However, small sample sizes and methodological heterogeneity across studies limit generalizability and preclude definitive conclusions regarding the role of gut microbiome in combat sports performance
Subgingival Plaque Removal Efficacy and Oral Soft Tissue Safety of the Wave Electric Toothbrush: An In Vitro and In Vivo Study
No full textBackground/Objectives: The novel wave electric toothbrush is considered potentially helpful in removing subgingival plaque to prevent the occurrence of periodontal diseases. This study aimed to assess the cleaning efficacy of a novel wave electric toothbrush on subgingival plaque and its safety profile for oral soft tissues. Methods: In vitro cleaning efficacy evaluations were conducted using oral dental models. The wave electric toothbrushes were divided into low-, medium-, and high-swing parameter groups, with manual brushing (Bass technique) as the control. Simulated plaque was applied to the buccal and gingival sulcus sites of the four first molars, and the plaque removal area and sulcus cleaning depth were measured. For safety evaluation, Sprague Dawley (SD) rats were brushed on their molars daily for 30 days, with bleeding incidents recorded. Oral soft tissues were analyzed through H&E staining and immunohistochemical analysis. Statistical analysis included ANOVA and Kruskal–Wallis (p < 0.05). Results: Medium- and high-swing groups demonstrated superior gingival sulcus cleaning efficacy, showing significant differences compared with the low-swing and control groups (p < 0.05). All swing parameters achieved complete plaque removal on buccal surfaces. No significant differences were observed between the low-swing and manual groups, or between the medium- and high-swing groups, regarding sulcus cleaning efficacy and maximum sulcus depth. During the 30-day in vivo experiment, medium- and high-swing groups showed low bleeding frequencies, primarily at the palatal gingiva and vestibule. Histological analyses indicated that higher swing parameters increased the likelihood of soft tissue injury. Conclusions: Wave electric toothbrushes enhance subgingival plaque removal, with higher swing parameters improving gingival sulcus cleaning. However, stronger parameters may increase the risk of soft tissue damage. Further clinical studies are required to establish optimal guidelines

Diagnostic Performance of HbA1c for Detecting OGTT-Diagnosed Diabetes in Obese Individuals with Suspected Prediabetes
No full textBackground: We aimed to investigate the diagnostic performance between the oral glucose tolerance test (OGTT) and HbA1c in diagnosing prediabetes and diabetes among obese individuals, and to evaluate the diagnostic performance of HbA1c for detecting OGTT-defined diabetes in obese individuals referred for evaluation of suspected prediabetes. Methods: Individuals with prediabetes were included between 1 January 2020 and 31 December 2022. Participants were categorized as mildly, moderately, morbidly, or super obese based on body mass index (BMI). According to the 75 g OGTT results, patients were classified into three groups: isolated impaired fasting glucose (IFG), combined IFG + impaired glucose tolerance (IGT), and overt type 2 diabetes mellitus (T2DM). The threshold HbA1c value for T2DM diagnosis in obese patients was determined based on OGTT outcomes. Results: Of the 139 prediabetic obese patients included, 115 (82.7%) were female, with a mean age of 45.18 ± 11.74 years. Based on BMI, 34 patients (24.5%) were mildly obese, 41 (29.5%) moderately obese, 49 (35.3%) morbidly obese, and 15 (10.8%) super obese. According to the 75 g OGTT results, 37.4% (n = 52) had isolated IFG, 45.3% (n = 63) had combined IFG + IGT, and 17.3% (n = 24) had overt T2DM. A weak–moderate positive correlation was observed between HbA1c and fasting blood glucose (Spearman’s rho = 0.263, p = 0.002). ROC–AUC analysis showed that HbA1c had significant discriminatory power in detecting T2DM diagnosed by the 75 g OGTT (AUC = 0.881, 95% CI: 0.816–0.946, p < 0.001). The optimal HbA1c cut-off was 6.15%, with 83.3% sensitivity and 80% specificity. The positive predictive value was 46.1%, and the negative predictive value was 95.8%. Conclusions: An HbA1c threshold of 6.15% demonstrated optimal performance for detecting OGTT-defined diabetes in obese individuals with suspected prediabetes. This value should not be interpreted as a population-wide diagnostic threshold. These findings indicate that HbA1c may serve as a useful screening tool to identify obese individuals who warrant confirmatory OGTT testing, rather than as a stand-alone diagnostic criterion. Further large-scale studies are warranted to confirm these results and support future clinical guidelines
