RESUMEN

Background: Extensive research has documented the positive impacts of physical activity on children and adolescents with Autism Spectrum Disorders (ASD). However, the specific benefits of various sports on the social functioning of children with ASD remain ambiguous. This study aims to employ a network meta-analysis to investigate the effects of different sports on the social functioning of children and adolescents with ASD and to establish a ranking of their effectiveness. Methods: This study conducted a comprehensive online search across Web of Science, PubMed, Cochrane, and Embase databases for randomized controlled trials and quasi-experimental studies focusing on social functioning outcomes. Data were synthesized using a Bayesian framework. Results: Sixteen relevant studies encompassing 560 participants were included. According to Cohen's classification, mini-basketball (SMD = 0.84, 95% CI: 0.46, 1.20), SPARK (SMD = 0.88, 95% CI: 0.06, 1.70), and Karate (SMD = 1.10, 95% CI: 0.27, 2.00) demonstrated high effect sizes, with Karate identified as the most effective intervention. Conversely, Combined Exercise and Nei Yang Gong interventions exhibited the least significant effects, falling below small effect sizes. Conclusion: Physical activity interventions have been shown to enhance social functioning in children and adolescents with ASD to varying extents, with Karate emerging as the most efficacious.

RESUMEN

Psoriasis is characterized by keratinocyte (KC) hyperproliferation and inflammatory cell infiltration, but the mechanisms remain unclear. In an imiquimod-induced mouse psoriasiform model, p38 activity is significantly elevated in KCs and p38α specific deletion in KCs ameliorates skin inflammation. p38α signaling promotes KC proliferation and psoriasis-related proinflammatory gene expression during psoriasis development. Mechanistically, p38α enhances KC proliferation and production of inflammatory cytokines and chemokines by activating STAT3. While p38α signaling in KCs does not affect the expression of IL-23 and IL-17, it substantially amplifies the IL-23/IL-17 pathogenic axis in psoriasis. The therapeutic effect of IL-17 neutralization is associated with decreased p38 and STAT3 activities in KCs and targeting the p38α-STAT3 axis in KCs ameliorates the severity of psoriasis. As IL-17 also highly activates p38 and STAT3 in KCs, our findings reveal a sustained signaling circuit important for psoriasis development, highlighting p38α-STAT3 axis as an important target for psoriasis treatment.

RESUMEN

Covalent organic frameworks (COFs) are one type of promising polymer semiconductors in solar-driven hydrogen production, but majority of COFs-based photocatalytic systems show low photocatalytic efficiency owing to lack of metal active sites. Herein, we reported II-Scheme heterojunction frameworks based on COF (TpPa-1) and metal-organic framework (HKUST-1) for highly efficient hydrogen production. The coordination bonding directed self-assembly of HKUST-1 on the surface of TpPa-1 endows the heterojunction frameworks (HKUST-1/TpPa-1) with strong interface interaction, optimized electronic structures and abundant redox active sites, thus remarkably boosting photocatalytic hydrogen evolution. The hydrogen evolution rate for optimal HKUST-1/TpPa-1 is as high as 10.50 mmol g-1 h-1, which is significantly enhanced when compared with that of their physical mixture (4.13 mmol g-1 h-1), TpPa-1 (0.013 mmol g-1 h-1) and Pt-based counterpart (6.70 mmol g-1 h-1). This work offers a facile approach to the construction of noble-metal-free II-Scheme heterojunctions based on framework materials for efficient solar energy conversion.

RESUMEN

The fabrication of sustainable structural materials with high physical properties to replace engineering plastics is a major challenge for modern industry, and wood, as the most abundant sustainable natural raw material on the planet, has received a great deal of attention from researchers. Researchers have made efforts to enhance the physical properties of wood in order to replace plastics. However, it is also difficult to meet practical demands at a low cost. Herein, we report a simple and efficient top-down strategy to transform bulk natural basswood into a high-performance structural material. This three-step strategy involves partial removal of hemicellulose and lignin via treating basswood by boiling an aqueous mixture of NaOH and Na2SO3, and a high-pressure steam treatment (HPST) was applied to delignified wood followed by hot-pressing, which allowed the wood to absorb moisture uniformly and quickly. HPST-treated dense delignified wood (HDDW) has a tensile strength of ~420 MPa, which is 6.5 times better than natural basswood (~65 MPa). We systematically investigated the various factors affecting the tensile strength of this wood material and explored the reasons why these factors affect the tensile strength, as well as the intrinsic connection between the moisture absorbed through HPST and the increased tensile strength of HDDW. Through our experiments, we realized the enhancement mechanism of HDDW and the optimal experimental conditions for the fabrication of HDDW.

RESUMEN

Background: Exercise has been reported to be associated with a reduced risk of nonalcoholic fatty liver disease (NAFLD), but there is no consensus on the role of weight changes in this association. This study aims to investigate whether the impact of exercise on NAFLD is mainly dependent on weight changes or is inherent to exercise itself. Methods: The study recruited 1671 Chinese NAFLD-free adults in 2019, and collected their exercise habits as well as 3 years of medical examination data including anthropometric measurements, blood biochemistry parameters, and liver ultrasound results. Univariate and multivariate logistic regression models were employed to examine the impact of exercise habits on NAFLD risk, with mediation analysis utilized to estimate the magnitude of the role of weight maintenance in the association between exercise and NAFLD. Results: After adjusting for confounders, moderate to high-intensity exercisers were 1.56 times (95% CIs = 1.09-2.22) more likely to successfully control their body weight, and therefore the weight-controlled group had a lower NAFLD risk of 34.9% (95% CIs = 21.8%-56.0%) compared to the weight-gain group. Mediation analysis reveals that exercise can significantly reduce the risk of NAFLD both through weight maintenance (37.1%) and independent of weight maintenance (62.9%). Conclusion: It might be more crucial to emphasize the adoption of regular moderate to high-intensity exercise for preventing NAFLD in the general population, rather than solely focusing on weight maintenance.

RESUMEN

Functionalized with the Au-S bond, gold nanoflares have emerged as promising candidates for theranostics. However, the presence of intracellular abundantly biothiols compromises the conventional Au-S bond, leading to the unintended release of cargoes and associated side-effects on non-target cells. Additionally, the hypoxic microenvironment in diseased regions limits treatment efficacy, especially in photodynamic therapy. To address these challenges, high-fidelity photodynamic nanoflares constructed on Pt-coated gold nanoparticles (Au@Pt PDNF) were communicated to avoid false-positive therapeutic signals and side-effects caused by biothiol perturbation. Compared with conventional photodynamic gold nanoflares (AuNP PDNF), the Au@Pt PDNF were selectively activated by cancer biomarkers and exhibited high-fidelity phototheranostics while reducing side-effects. Furthermore, the ultrathin Pt-shell catalysis was confirmed to generate oxygen which alleviated hypoxia-related photodynamic resistance and enhanced the antitumor effect. This design might open a new venue to advance theranostics performance and is adaptable to other theranostic nanomaterials by simply adding a Pt shell.

RESUMEN

Background: With the rapid development of shear wave elastography technology, the clinical application prospect of two-dimensional shear wave elastography (2D SWE) for non-invasive monitoring of liver fibrosis is extremely promising. This study aimed to evaluate the diagnostic performance of ElastQ, a noval 2D SWE method, in the staging of liver fibrosis in patients with chronic hepatitis B with histopathological results as the reference standard. Methods: Between August 2020 and December 2021, a prospective multicenter study of 602 consecutive patients with chronic hepatitis B was conducted in 14 hospitals. All patients underwent liver biopsy and 2D SWE examination. The patients were divided into a training cohort and a validation cohort. The area under the receiver operating characteristic curve (AUROC) was calculated, and the optimal cut-off values for ElastQ were obtained. Results: Overall, 2D SWE values showed a strong correlation with fibrosis stage (r=0.71, P<0.001). In the training cohort, the AUROCs of ElastQ for diagnosing fibrosis stages ≥S1, ≥S2, ≥S3, and S4 were 0.817 [95% confidence interval (CI): 0.777-0.853), 0.887 (95% CI: 0.852-0.915), 0.912 (95% CI: 0.881-0.937), and 0.832 (95% CI: 0.793-0.866)], respectively. In the validation cohort, the AUROCs of ElastQ for diagnosing fibrosis stages ≥S1, ≥S2, ≥S3, and S4 were 0.807 (95% CI: 0.742-0.861), 0.868 (95% CI: 0.810-0.914), 0.855 (95% CI: 0.796-0.903), and 0.851 (95% CI: 0.791-0.900), respectively. The optimal liver stiffness cut-off values for the identification of fibrosis stages ≥S1, ≥S2, ≥S3, and S4 were 5.72 kPa (sensitivity: 78%, specificity: 70%), 6.85 kPa (sensitivity: 77%, specificity: 86%), 7.43 kPa (sensitivity: 80%, specificity: 86%), and 8.03 kPa (sensitivity: 81%, specificity: 73%), respectively. Conclusions: Two-dimensional SWE can accurately stage liver fibrosis in patients with chronic hepatitis B.

RESUMEN

BACKGROUND: Globally, child maltreatment has become a serious problem, affecting individuals' physical and mental health. This meta-analysis aimed to explore the association between child maltreatment and social anxiety. METHODS: MEDLINE, PsycINFO, EMBASE, Scopus, and Web of Science were searched for articles published by October 2021. Newcastle-Ottawa Quality Assessment Scale (NOS) was used to evaluate the quality of studies. Maltreatment type, sample setting, age, country and measurement instruments were analyzed as moderators. RESULTS: Twenty-nine studies met the inclusion criteria. Child maltreatment was positively correlated with social anxiety (r = 0.201, 95 % CI [0.171, 0.230]). The moderating effect of maltreatment subtypes was significant whether divided into three types (Qb = 12.152, p = .002), or five types (Qb = 11.574, p = .021). Specifically, emotional maltreatment (r = 0.251, 95 % CI [0.201, 0.298]) had a stronger relationship with social anxiety than physical (r = 0.138, 95 % CI [0.085, 0.191]; Qb = 9.312, p = .002) and sexual maltreatment (r = 0.153, 95 % CI [0.108, 0.197]; Qb = 9.197, p = .002). However, there was no significant difference in the effect size between physical and sexual maltreatment (Qb = 0.096, p = .757). Other variables (age, sample setting and country) were not significant moderators. LIMITATIONS: Only twenty-nine studies were included, and there was high heterogeneity among the studies, the interpretation of the results should be cautious. CONCLUSIONS: This meta-analysis confirmed the relationship between child maltreatment and social anxiety, especially highlight the harmfulness of emotional maltreatment.

RESUMEN

This study adapts a Medical English Language Anxiety Scale (MELAS) based on Horwitz's Foreign Language Classroom Anxiety Scale (FLCAS) and examines students' anxiety in medical English vocabulary, listening and speaking, communication, literature reading, and academic paper writing. The biographical factors related to medical English language anxiety (MELA) were also tested. The questionnaire sets including five dimensions were distributed to the students from a medical university in Sichuan, China, and were statistically analyzed by using SPSS 22.0 and AMOS 21.0. By employing the adapted MELAS, it was found that 85.2% of the medical students surveyed suffered moderate and higher anxiety. Among all dimensions, students with listening and speaking anxiety recorded the highest (89.3%), followed by literature reading anxiety (86.6%), English academic writing anxiety (85.9%), communication anxiety (81.9%), and vocabulary learning anxiety (81.2%). We also found that the anxiety of rural medical students in each dimension was higher than that of urban medical students. This study suggests that English teachers should be fully aware of their students' language anxiety situation, design interesting class activities, and create a relaxed English learning atmosphere in classroom teaching to make students less nervous when learning medical English in class.

RESUMEN

Facial artery pseudoaneurysms are rare and mostly a result of blunt injury. Since the facial arteries are well protected by facial soft tissue and the lumen of the facial artery is thin and small in diameter, a sharp injury usually leads to complete transection rather than partial laceration of the blood vessel. As a non-invasive method, ultrasound does not involve radiation and sedation. Diagnosis of facial artery pseudoaneurysms is most commonly made with ultrasound, and Doppler ultrasound is essential. On grayscale imaging, facial artery pseudoaneurysms often appearanced of a fluid collection, Color Doppler imaging often show a well-defined swirl pattern named "yin and yang sign," the Spectral Doppler showed a diagnostic "to and fro" two-phase bidirectional arterial blood flow spectrum. It's particularly for the examination of facial artery pseudoaneurysms in children. Here, we report a case of facial foreign body abscess and facial artery pseudoaneurysm in a 19-month-old child 1 week after a sharpness injury that was diagnosed by ultrasound.

RESUMEN

Two-dimensional (2D) Dirac materials have attracted intense research efforts due to their promise for applications ranging from field-effect transistors and low-power electronics to fault-tolerant quantum computation. One key challenge is to fabricate 2D Dirac materials hosting Dirac electrons. Here, monolayer germanene is successfully fabricated on a Ag2Ge surface alloy. Scanning tunneling spectroscopy measurements revealed a linear energy dispersion relation. The latter was supported by density functional theory calculations. These results demonstrate that monolayer germanene can be realistically fabricated on a Ag2Ge surface alloy. The finding opens the door to exploration and study of 2D Dirac material physics and device applications.
