ABSTRACT
INTRODUCTION: Presenting health information at a sixth-grade reading level is advised to accommodate the general public's abilities. Breast cancer (BC) is the second-most common malignancy in women, but the readability of online BC information in English and Spanish, the two most commonly spoken languages in the United States, is uncertain. METHODS: Three search engines were queried using: "how to do a breast examination," "when do I need a mammogram," and "what are the treatment options for breast cancer" in English and Spanish. Sixty websites in each language were studied and classified by source type and origin. Three readability frameworks in each language were applied: Flesch Kincaid Reading Ease, Flesch Kincaid Grade Level, and Simple Measure of Gobbledygook (SMOG) for English, and Fernández-Huerta, Spaulding, and Spanish adaptation of SMOG for Spanish. Median readability scores were calculated, and corresponding grade level determined. The percentage of websites requiring reading abilities >sixth grade level was calculated. RESULTS: English-language websites were predominantly hospital-affiliated (43.3%), while Spanish websites predominantly originated from foundation/advocacy sources (43.3%). Reading difficulty varied across languages: English websites ranged from 5th-12th grade (Flesch Kincaid Grade Level/Flesch Kincaid Reading Ease: 78.3%/98.3% above sixth grade), while Spanish websites spanned 4th-10th grade (Spaulding/Fernández-Huerta: 95%/100% above sixth grade). SMOG/Spanish adaptation of SMOG scores showed lower reading difficulty for Spanish, with few websites exceeding sixth grade (1.7% and 0% for English and Spanish, respectively). CONCLUSIONS: Online BC resources have reading difficulty levels that exceed the recommended sixth grade, although these results vary depending on readability framework. Efforts should be made to establish readability standards that can be translated into Spanish to enhance accessibility for this patient population.
ABSTRACT
COP9 signalosome catalytic subunit CSN5 plays a key role in tumorigenesis and tumor immunity, showing potential as an anticancer target. Currently, only a few CSN5 inhibitors have been reported, at least partially, due to the challenges in establishing assays for CSN5 deubiquitinase activity. Here, we present the establishment and validation of a simple and reliable non-catalytic activity assay platform for identifying CSN5 inhibitors utilizing a new fluorescent probe, CFP-1, that exhibits enhanced fluorescence and fluorescence polarization features upon binding to CSN5. By using this platform, we identified 2-aminothiazole-4-carboxylic acids as new CSN5 inhibitors, which inhibited CSN5 but slightly downregulated PD-L1 in cancer cells. Furthermore, through the integration of deep learning-enabled virtual screening, we discovered that shikonins are nanomolar CSN5 inhibitors, which can upregulate PD-L1 in HCT116 cells. The binding modes of these structurally distinct inhibitors with CSN5 were explored by using microsecond-scale molecular dynamics simulations and tryptophan quenching assays.
ABSTRACT
Nanoplastics at environmentally relevant concentrations (ERCs) could cause transgenerational toxicity on organisms. Caenorhabditis elegans is an important model for the study of transgenerational toxicology of pollutants. Nevertheless, the underlying mechanisms for the control of transgenerational nanoplastic toxicity by germline signals remain largely unclear. In C. elegans, exposure to 1-100 µg/L polystyrene nanoparticle (PS-NP) decreased expression of germline ced-1 encoding a G protein-coupled receptor at parental generation (P0-G). After PS-NP exposure at P0-G, transgenerational decrease in germline ced-1 expression could be detected. Meanwhile, the susceptibility to transgenerational PS-NP toxicity was observed in ced-1(RNAi) animals. After PS-NP exposure at P0-G, germline RNAi of ced-1 increased expressions of met-2 and set-6 encoding histone methylation transferases. The susceptibility of ced-1(RNAi) to transgenerational PS-NP toxicity could be inhibited by RNAi of met-2 and set-6. Moreover, in PS-NP exposed met-2(RNAi) and set-6(RNAi) nematodes, expressions of ins-39, wrt-3, and/or efn-3 encoding secreted ligands were decreased. Therefore, our results demonstrated that inhibition in germline CED-1 mediated the toxicity induction of nanoplastics at ERCs across multiple generations in nematodes.
ABSTRACT
BACKGROUND: The association between dietary magnesium (Mg) intake and the risk of atherosclerotic cardiovascular disease (ASCVD) remains uncertain. We aimed to examine the associations of dietary Mg intake with the risk of ASCVD events and mortality in individuals with and without type 2 diabetes. METHODS: A total of 149,929 participants (4603 with type 2 diabetes) from the UK Biobank were included in the analyses. The hazard ratios (HRs) and 95 % confidence intervals (CIs) were estimated using Cox proportional hazard models. Furthermore, interactions of dietary Mg intake with type 2 diabetes status were examined on multiplicative and additive scales. RESULTS: During a median follow-up of 12.0 and 12.1 years, 7811 incident ASCVD events and 5000 deaths (including 599 ASCVD deaths) were documented, respectively. There were significantly negative associations between sufficient dietary Mg intake (equal to or greater than the recommended daily intake) and the risk of ASCVD incidence (HR 0.63 [95 % CI 0.49;0.82]), ASCVD mortality (0.45 [0.24;0.87]), and all-cause mortality (0.71 [0.52;0.97]) in participants with type 2 diabetes, whereas no significant association was observed in participants without type 2 diabetes (1.01 [0.94;1.09] for ASCVD incidence; 1.25 [0.93;1.66] for ASCVD mortality; 0.97 [0.88;1.07] for all-cause mortality). Multiplicative and additive interactions of dietary Mg intake with type 2 diabetes status were both observed. CONCLUSION: Sufficient dietary Mg intake was significantly associated with lower risks of ASCVD events and mortality in individuals with type 2 diabetes but not in those without type 2 diabetes. Our findings provide insight into the importance of dietary Mg intake for reducing modifiable cardiovascular burden in individuals with type 2 diabetes, which may inform future personalized dietary guidelines.
ABSTRACT
Background: Fecal microbiota transplantation (FMT) is recommended for treating patients with recurrent Clostridioides difficile infection (CDI). However, the therapeutic efficacy of FMT in elderly patients with complex medical conditions remains uncertain. The new method of FMT, washed microbiota transplantation (WMT) has been widely used in China to improve the safety of transplantation. Case report: A 94-year-old man with chronic lymphocytic leukemia (CLL) was admitted to our hospital due to recurrent diarrhea persisting for eight months. The patient had experienced multiple relapses of CDI despite receiving standard therapies. He underwent colonic transendoscopic enteral tubing (TET) and subsequently received WMT during the procedure. Following the treatment, no episodes of diarrhea or adverse events were observed, and the patient remained stable over a three-month follow-up period. Conclusion: This case demonstrates the efficacy and safety of WMT in treating elderly patients with CLL. The successful management of this case offers valuable clinical insights into the use of WMT for elderly CDI patients with complex medical conditions. Moreover, this report contributes practical experience regarding the administration of WMT through the colonic TET.
ABSTRACT
It is well known that aquaculture can alter the microenvironments of lakes at sediment-water interface (SWI). However, the main mechanisms underlying the effects of aquaculture activities on arsenic (As) transformations are still unclear. In this context, the present study aims to investigate the variations in the sediment As contents in Yangcheng Lake, as well as to assess its chemical transformations, release fluxes, and release mechanisms. The results showed substantial spatial differences in the dissolved As concentrations in the sediment pore water. The As release fluxes at the SWI ranged from 1.32 to 112.09 µg/L, with an average value of 33.68 µg/L. In addition, the highest As fluxes were observed in the aquaculture areas. The transformation of crystalline hydrous Fe oxide-bound As to adsorbed-As in the aquaculture lake sediments increased the ability of As release. The Partial least squares path modeling results demonstrated the great contributions of organic matter (OM) to the As transformations by influencing the sediment microbial communities and Fe/Mn minerals. The changes in the As fractionation and competing adsorption increased the dissolved As concentrations in the 0-10 mm surface sediment. Non-specifically and specifically adsorbed As were the major sources of dissolved As in the sediments. Specifically, microbial reduction of As[V] and dissolution of Fe oxides increased the dissolved As concentrations at the SWI (20 to -20 mm). The results of the current study highlight the positive enhancement effects of aquaculture on As release from sediments.

INTRODUCTION: Parathyroidectomy is recommended for severe secondary hyperparathyroidism (SHPT) due to end-stage kidney disease (ESKD), but surgery is underutilized. High quality and accessible online health information, recommended to be at a 6th-grade reading level, is vital to improve patient health literacy. This study evaluated available online resources for SHPT from ESKD based on information quality and readability. METHODS: Three search engines were queried using the terms "parathyroidectomy for secondary hyperparathyroidism," "parathyroidectomy kidney/renal failure," "parathyroidectomy dialysis patients," "should I have surgery for hyperparathyroidism due to kidney failure?," and "do I need surgery for hyperparathyroidism due to kidney failure if I do not have symptoms?" Websites were categorized by source and origin. Two independent reviewers determined information quality using JAMA (0-4) and DISCERN (1-5) frameworks, and scores were averaged. Cohen's kappa evaluated inter-rater reliability. Readability was determined using the Flesch Kincaid Reading Ease, Flesch Kincaid Grade Level, and Simple Measure of Gobbledygook tools. Median readability scores were calculated, and corresponding grade level determined. Websites with reading difficulties >6th grade level were calculated. RESULTS: Thirty one (86.1%) websites originated from the U.S., with most from hospital-associated (63.9%) and foundation/advocacy sources (30.6%). The mean JAMA and DISCERN scores for all websites were 1.3 ± 1.4 and 2.6 ± 0.7, respectively. Readability scores ranged from grade level 5-college level, and most websites scored above the recommended 6th grade level. CONCLUSIONS: Patient-oriented websites tailoring SHPT from ESKD are at a reading level higher than recommended, and the quality of information is low. Efforts must be made to improve the accessibility and quality of information for all patients.
ABSTRACT
Intercropping is a sustainable strategy recognized for boosting crop production and mitigating heavy metal toxicity in contaminated soils. This study investigates the effects of biochar amendments on Pb-contaminated soil, utilizing monocropping and intercropping techniques with C. olitorius and Z. mays. The research assesses Pb removal capacity, nutrient uptake, antioxidant enzymes, and soil Pb fractionation. In monocropping, the phytoremediation ratio for C. olitorius increased from 16.67 to 27.33%, while in intercropping, it rose from 19.00 to 28.33% with biochar amendments. Similarly, Z. mays exhibited an increased phytoremediation ratio from 53.33 to 74.67% in monocropping and from 63.00 to 78.67% in intercropping with biochar amendments. Intercropping significantly increased the peroxidase (POD) activity in Z. mays roots by 22.53%, and there were notable increases in shoot POD of C. olitorius (11.54%) and Z. mays (16.20%) with biochar application. CAT showed consistent improvements, increasing by 37.52% in C. olitorius roots and 74.49% in Z. mays roots with biochar. Biochar amendments significantly increased N content in soil under sole cropping of Z. mays and intercropping systems. In contrast, Cu content increased by 56.34%, 59.05%, and 79.80% in monocropping (C. olitorius and Z. mays) and intercropping systems, respectively. This suggests that biochar enhances nutrient availability, improving phytoremediation efficacy in Pb-contaminated soil. Phyto availability of trace metals (Zn, Mn, Cu, and Fe) exhibited higher levels with biochar amendments than those without. The findings indicate that intercropping and biochar amendments elevate antioxidant enzyme levels, reducing reactive oxygen species and mitigating Pb toxicity effects. This approach improves phytoremediation efficiency and holds promise for soil pollution remediation while enhancing nutrient content and crop quality in Pb-contaminated soil.

Probiotic lactic acid bacteria have been widely studied, but much less was focused on probiotic yeasts in food systems. In this study, probiotic Saccharomyces cerevisiae var. boulardii CNCM I-745 was employed to prepare ice cream added with and without inulin (1%, w/v). Metabolomics analysis on the effect of inulin showed 84 and 147 differentially expressed metabolites identified in the ice cream samples from day 1 and day 30 of storage (-18 °C), respectively. Various potential functional metabolites were found, including citric acid, ornithine, D-glucuronic acid, sennoside A, stachyose, maltotetraose, maltopentaose, maltohexaose, maltoheptaose, cis-aconitic acid, gamma-aminobutyric acid, L-threonine, L-glutamic acid, tryptophan, benzoic acid, and trehalose. Higher expression of these metabolites suggested their possible roles through relevant metabolic pathways in improving survivability of the probiotic yeast and functionality of ice cream. This study provides further understanding on the metabolic characteristics of probiotic yeast that potentially affect the functionality of ice cream.

The secretory glutaminyl cyclase (sQC) and Golgi-resident glutaminyl cyclase (gQC) are responsible for N-terminal protein pyroglutamation and associated with various human diseases. Although several sQC/gQC inhibitors have been reported, only one inhibitor, PQ912, is currently undergoing clinic trials for the treatment of Alzheimer's disease. We report an X-ray crystal structure of sQC complexed with PQ912, revealing that the benzimidazole makes "anchor" interactions with the active site zinc ion and catalytic triad. Structure-guided design and optimization led to a series of new benzimidazole derivatives exhibiting nanomolar inhibition for both sQC and gQC. In a MPTP-induced Parkinson's disease (PD) mouse model, BI-43 manifested efficacy in mitigating locomotor deficits through reversing dopaminergic neuronal loss, reducing microglia, and decreasing levels of the sQC/gQC substrates, α-synuclein, and CCL2. This study not only offers structural basis and new leads for drug discovery targeting sQC/gQC but also provides evidence supporting sQC/gQC as potential targets for PD treatment.

INTRODUCTION: Patients use the internet to learn more about health conditions. Non-English-speaking patients may face additional challenges. The quality of online breast cancer information, the most common cancer in women, is uncertain. This study aims to examine the quality of online breast cancer information for English and non-English-speaking patients. METHODS: Three search engines were queried using the terms: "how to do a breast examination," "when do I need a mammogram," and "what are the treatment options for breast cancer" in English, Spanish, and Chinese. For each language, 60 unique websites were included and classified by type and information source. Two language-fluent reviewers evaluated website quality using the Journal of American Medical Association benchmark criteria (0-4) and the DISCERN tool (1-5), with higher scores representing higher quality. Scores were averaged for each language. Health On the Net code presence was noted. Inter-rater reliability between reviewers was assessed. RESULTS: English and Spanish websites most commonly originated from US sources (92% and 80%, respectively) compared to Chinese websites (33%, P < 0.001). The most common website type was hospital-affiliated for English (43%) and foundation/advocacy for Spanish and Chinese (43% and 45%, respectively). English websites had the highest and Chinese websites the lowest mean the Journal of American Medical Association (2.2 ± 1.4 versus 1.0 ± 0.8, P = 0.002) and DISCERN scores (3.5 ± 0.9 versus 2.3 ± 0.6, P < 0.001). Health On the Net code was present on 16 (8.9%) websites. Inter-rater reliability ranged from moderate to substantial agreement. CONCLUSIONS: The quality of online information on breast cancer across all three languages is poor. Information quality was poorest for Chinese websites. Improvements to enhance the reliability of breast cancer information across languages are needed.

Phthalates are positioned as potential risk factors for health-related diseases. However, the effects of exposure to phthalates on accelerated aging and the potential modifications of physical activity remain unclear. A total of 2317 participants containing complete study-related information from the National Health and Nutrition Examination Survey 2007-2010 were included in the current study. We used two indicators, the Klemera-Doubal method biological age acceleration (BioAgeAccel) and phenotypic age acceleration (PhenoAgeAccel), to assess the accelerated aging status of the subjects. Multiple linear regression (single pollutant models), weighted quantile sum (WQS) regression, Quantile g-computation, and Bayesian kernel machine regression (BKMR) models were utilized to explore the associations between urinary phthalate metabolites and accelerated aging. Three groups of physical activity with different intensities were used to evaluate the modifying effects on the above associations. Results indicated that most phthalate metabolites were significantly associated with BioAgeAccel and PhenoAgeAccel, with effect values (ß) ranging from 0.16 to 0.21 and 0.16-0.37, respectively. The WQS indices were positively associated with BioAgeAccel (0.33, 95% CI: 0.11, 0.54) and PhenoAgeAccel (0.50, 95% CI: 0.19, 0.82). Quantile g-computation indicated that phthalate mixtures were associated with accelerated aging, with effect values of 0.15 (95% CI: 0.02, 0.28) for BioAgeAccel and 0.39 (95% CI: 0.12, 0.67) for PhenoAgeAccel respectively. The BKMR models indicated a significant positive association between the concentrations of urinary phthalate mixtures with the two indicators. In addition, we found that most phthalate metabolites showed the strongest effects on accelerated aging in the no physical activity group and that the effects decreased gradually with increasing levels of physical activity (P < 0.05 for trend). Similar results were also observed in the mixed exposure models (WQS and Quantile g-computation). This study indicates that phthalates exposure is associated with accelerated aging, while physical activity may be a crucial barrier against phthalates exposure-related aging.

OBJECTIVE: To investigate the relationship between ambient fine particulate matter (PM2.5) exposure and fecundability. METHODS: This study included 751,270 female residents from Henan Province who participated in the National Free Pre-conception Check-up Projects during 2015-2017. Ambient cycle-specific PM2.5 exposure was assessed at the county level for each participant using satellite-based PM2.5 concentration data at 1-km resolution. Cox proportional hazards models with time-varying exposure were used to estimate the association between fecundability and PM2.5 exposure, adjusted for potential individual risk factors. RESULTS: During the study period, 568,713 participants were pregnant, monthly mean PM2.5 concentrations varied from 25.5 to 114.0 µg/m3 across study areas. For each 10 µg/m3 increase in cycle-specific PM2.5, the hazard ratio for fecundability was 0.951 (95 % confidence interval: 0.950-0.953). The association was more pronounced in women who were older, with urban household registration, history of pregnancy, higher body mass index (BMI), hypertension, without exposure to tobacco, or whose male partners were older, with higher BMI, or hypertension. CONCLUSION: In this population-based prospective cohort, ambient cycle-specific PM2.5 exposure was associated with reduced fecundability. These findings may support the adverse implications of severe air pollution on reproductive health.

Poverty is a known risk factor for burn injury and is associated with residency in food deserts and food swamps. Our aim was to determine the prevalence of residency in food deserts and food swamps and to investigate the relationship between food environment, comorbidities, and wound healing in patients with burns. We performed a retrospective chart review of all patients with burns aged ≥ 18 seen in the emergency department or admitted to the burn service at an American Burn Association-verified urban academic center between January 2016 and January 2022. Patient GeoIDs were used to classify residency in food deserts and food swamps, and comorbidities and demographics were recorded. A subset of patients with <20% total body surface area burns who underwent single-operation split-thickness skin grafting was identified for wound healing analysis. A total of 3063 patients were included, with 206 in the heal time analysis. In total, 2490 (81.3%) lived in food swamps and 96 (3.1%) lived in food deserts. Diabetes, hypertension, and tobacco smoking were more prevalent in food swamps than in food deserts or good access areas. While there was no significant effect of the food environment on wound healing, diabetes was associated with longer healing times. Most patients with burns reside in food swamps, which are associated with a higher prevalence of hypertension, diabetes, and smoking. The food environment was not significantly associated with wound healing. Not having diabetes was associated with a shorter time for wound healing.

Conditional power (CP) serves as a widely utilized approach for futility monitoring in group sequential designs. However, adopting the CP methods may lead to inadequate control of the type II error rate at the desired level. In this study, we introduce a flexible beta spending function tailored to regulate the type II error rate while employing CP based on a predetermined standardized effect size for futility monitoring (a so-called CP-beta spending function). This function delineates the expenditure of type II error rate across the entirety of the trial. Unlike other existing beta spending functions, the CP-beta spending function seamlessly incorporates beta spending concept into the CP framework, facilitating precise stagewise control of the type II error rate during futility monitoring. In addition, the stopping boundaries derived from the CP-beta spending function can be calculated via integration akin to other traditional beta spending function methods. Furthermore, the proposed CP-beta spending function accommodates various thresholds on the CP-scale at different stages of the trial, ensuring its adaptability across different information time scenarios. These attributes render the CP-beta spending function competitive among other forms of beta spending functions, making it applicable to any trials in group sequential designs with straightforward implementation. Both simulation study and example from an acute ischemic stroke trial demonstrate that the proposed method accurately captures expected power, even when the initially determined sample size does not consider futility stopping, and exhibits a good performance in maintaining overall type I error rates for evident futility.

Cluster randomization trials with survival endpoint are predominantly used in drug development and clinical care research when drug treatments or interventions are delivered at a group level. Unlike conventional cluster randomization design, stratified cluster randomization design is generally considered more effective in reducing the impacts of imbalanced baseline prognostic factors and varying cluster sizes between groups when these stratification factors are adopted in the design. Failure to account for stratification and cluster size variability may lead to underpowered analysis and inaccurate sample size estimation. Apart from the sample size estimation in unstratified cluster randomization trials, there are no development of an explicit sample size formula for survival endpoint when a stratified cluster randomization design is employed. In this article, we present a closed-form sample size formula based on the stratified cluster log-rank statistics for stratified cluster randomization trials with survival endpoint. It provides an integrated solution for sample size estimation that account for cluster size variation, baseline hazard heterogeneity, and the estimated intracluster correlation coefficient based on the preliminary data. Simulation studies show that the proposed formula provides the appropriate sample size for achieving the desired statistical power under various parameter configurations. A real example of a stratified cluster randomization trial in the population with stable coronary heart disease is presented to illustrate our method.

In this study, a novel Fe3O4-based biochar coupled surface-imprinted polymer was constructed via simple hydrothermal route for salicylic acid recognition and degradation in advanced oxidation processes. The material exhibited excellent adsorption capability, up to 118.23 mg g-1, and efficient degradation performance, 87.44% removal rate within 240 min, based on integrating the advantages of both huge specific surface area as well as abundant functional groups from biochars and specific recognition sites from imprinted cavities. Moreover, high selectivity coefficient (11.67) showed stable recognition in single and binary systems. SO4â¢- and â¢OH were confirmed as reactive oxygen species in catalytic reaction according to quenching experiments and EPR analysis. The degradation mechanism and pathway were unraveled by DFT calculations and LC-MS. Furthermore, the results of toxicity evaluation, stability and reusability demonstrated application potential in the field of water environment restoration. This study confirmed that molecular imprinting provided a promising solution to targeted removal of emerging environmental pollutants by degrading after the enrichment of pollutants to the composites surface.

BACKGROUND: The relationship between theoretically relevant psychosocial and behavioral variables and outcomes of metabolic and bariatric surgery remains unclear. Some studies have found that the presence of psychopathology, disordered eating, and impulsivity, either before surgery or during the early postoperative period, is associated with suboptimal postoperative weight loss. Other studies have not found these relationships. OBJECTIVE: Examine the relationship between psychopathology, disordered eating, impulsivity, and weight loss 24 months postoperatively. SETTING: Two large, urban university health systems. METHODS: Participant characteristics were collected using validated interviews, patient-reported outcome measures, and computerized assessment methods. Linear mixed effect models were used to test the association of the variables of interest on percent weight loss (%WL). RESULTS: Three hundred participants were enrolled at baseline; weight data at 24 months were available for 227 participants; between 181 and 53 individuals completed other outcome measures. The mean %WL was 23.3 ± 9.9% at 24 months. Patients who underwent Roux-en-Y gastric bypass lost more weight than those who underwent sleeve gastrectomy. The presence of subjective binge episodes at baseline was related to a greater %WL at 24 months; there were no other baseline predictors. The presence of eating disorder diagnoses and disordered eating symptoms after surgery were associated with smaller weight losses over 24 months. Current and lifetime psychopathology and impulsivity were unrelated to %WL at 24 months. CONCLUSION: Disordered eating after bariatric surgery was associated with a smaller %WL at postoperative year 2. Additional monitoring of these symptoms in the early postoperative period is recommended. Psychotherapeutic and/or dietary interventions may promote more optimal weight loss outcomes.

Ulcerative colitis (UC) is a global intestinal disease, and conventional therapeutic drugs often fail to meet the needs of patients. There is an urgent need to find efficient and affordable novel biological therapies. Saccharomyces boulardii has been widely used in food and pharmaceutical research due to its anti-inflammatory properties and gut health benefits. However, there is still a relatively limited comparison and evaluation of different forms of S. boulardii treatment for UC. This study aimed to compare the therapeutic effects of S. boulardii, heat-killed S. boulardii, and S. boulardii ß-glucan on UC, to explore the potential of heat-killed S. boulardii as a new biological therapy. The results demonstrate that all three treatments were able to restore body weight, reduce the disease activity index (DAI), inhibit splenomegaly, shorten colon length, and alleviate histopathological damage to colonic epithelial tissues in DSS-induced colitis mice. The oral administration of S. boulardii, heat-killed S. boulardii, and S. boulardii ß-glucan also increased the levels of tight junction proteins (Occludin and ZO-1), decreased the levels of pro-inflammatory cytokines (TNF-α, IL-1ß, and IL-6) in the serum, and suppressed the expressions of TNF-α, IL-1ß, and IL-6 mRNA in the colon. In particular, in terms of gut microbiota, S. boulardii, heat-killed S. boulardii, and S. boulardii ß-glucan exhibited varying degrees of modulation on DSS-induced dysbiosis. Among them, heat-killed S. boulardii maximally restored the composition, structure, and functionality of the intestinal microbiota to normal levels. In conclusion, heat-killed S. boulardii showed greater advantages over S. boulardii and S. boulardii ß-glucan in the treatment of intestinal diseases, and it holds promise as an effective novel biological therapy for UC. This study is of great importance in improving the quality of life for UC patients and reducing the burden of the disease.

Objective: Obesity and substance use are leading preventable causes of mortality, yet their origins in violence remain poorly understood. This study examined child maltreatment in relation to obesity and symptoms consistent with substance use disorder (SUD) in late adolescence, determining the roles of the child maltreatment type and timing, and gender. Methods: The sample (N = 1,161) was drawn from the Longitudinal Studies of Child Abuse and Neglect. Obesity and SUD were measured at 18-years. Lifetime child protective services records and youth self-reports indicated physical abuse, sexual abuse, supervisory neglect, failure-to-provide neglect, and emotional maltreatment during early childhood, middle childhood, and adolescence. Results: In the overall sample, emotional maltreatment during adolescence was associated with obesity (OR = 2.03, 95% CI: 1.25, 3.30) and SUD (OR = 2.00, 95% CI: 1.20, 3.35), and adolescent physical abuse with obesity (OR = 2.20, 95% CI: 1.36, 3.58). In girls, early childhood physical abuse was associated with SUD (OR = 2.35, 95% CI: 1.08, 5.12), and emotional maltreatment during adolescence with obesity (OR = 2.16, 95% CI: 1.10, 4.23) and SUD (OR = 3.21, 95% CI: 1.37, 7.3 5). Adolescent physical abuse and obesity were associated in boys (OR = 3.18, 95% CI: 1.45, 6.98). Gender moderation was identified for an inverse relationship between supervisory neglect and obesity in girls (OR = .26, 95% CI: .07, .99). Conclusions: Type and timing contribute to the effects of child maltreatment, contingent upon gender. Intervention focused on adolescent emotional maltreatment may reduce both SUD and obesity.
