Responses of leaf functional traits of different grassland plants to desertification and their adaptation strategies

Ying Yong Sheng Tai Xue Bao. 2025 Aug;36(8):2379-2387. doi: 10.13287/j.1001-9332.202508.006.

ABSTRACT

We examined the responses of leaf functional traits and their adaptation strategies of four dominant species (Lespedeza davurica, Carex duriuscula, Potentilla chinensis, and Cleistogenes chinensis) to desertification in the Zhanggutai desertified grassland, Liaoning Province. We measured the morphological and chemical functional traits under five desertification levels (0%, 10%, 30%, 50%, and 70% of sand addition by mass). The results showed that desertification significantly affected leaf functional traits in the natural grasslands of northwestern Liao-ning, but with significant species-specific difference. With the increases of desertification intensity, specific leaf area of C. duriuscula and P. chinensis increased initially and then decreased, peaking at 30% and 10% sand addition levels, respectively. Leaf dry matter content of the four species all showed a decreasing trend with aggravated desertification, but the changes were not statistically significant. Desertification significantly increased leaf N and P contents of C. duriuscula and C. chinensis, with N content being increased by 45.8% and 28.2%, and P content being increased by 87.1% and 50.3%, respectively under 70% sand addition treatment. The four species adapted to desertification through trade-offs among morphological and chemical traits. P. chinensis exhibited a “low-input, high-benefit” resource-conservative strategy. L. davurica maintained relatively stable leaf nutrient content. Both species exhibited a relatively strong adaptability to desertification.

Evaluation of an interactive educational intervention to improve nutritional practices for premature infants

Matern Health Neonatol Perinatol. 2025 Sep 1;11(1):26. doi: 10.1186/s40748-025-00222-x.

ABSTRACT

This pilot randomized trial study evaluated the effectiveness of the Pebbles of Hope Thrive Guide, an interactive educational course designed for parents of premature infants. The study assessed changes in breastfeeding practices, maternal nutrition, and use of Kangaroo Care among 50 mothers in total randomized to one of three groups: Supervised, Independent, or Control. The purpose of the study was to assess the provision of mother’s breast milk, improved material nutrition behaviors, and adoption of Kangaroo Care among mothers that received access to the course compared to those that received standard education without Thrive Guide access. The primary outcome assessed was the provision of breast milk at three months post-intervention, while secondary outcomes included improvements in maternal confidence, changes in maternal nutrition behaviors, the adoption and frequency of providing Kangaroo Care, and the impact of educator supervision. Although the intervention improved mothers’ confidence and knowledge, it did not significantly impact breast milk provision or maternal nutrition behaviors at 3 months. Breast milk provision declined across all groups, but the amount of decline was not statistically different between them. Similarly, no significant differences were observed in the number of nutritional improvements made between the two periods. However, Independent users exhibited a notable increase in Kangaroo Care frequency. Qualitative interviews highlighted the importance of ongoing support and addressing practical barriers to following nutritional guidelines. These findings suggest that further research is needed to explore the conditions that enhance long-term behavior change and to identify strategies that optimize the impact of educational interventions on caregiving practices.

Nutritional-inflammatory balance assessed by advanced lung cancer inflammation index and its association with all-cause mortality in coronary heart disease : a retrospective cohort study

J Health Popul Nutr. 2025 Aug 31;44(1):317. doi: 10.1186/s41043-025-01063-2.

ABSTRACT

OBJECTIVE: The present study aimed to evaluate the association between advanced lung cancer inflammation index (ALI) and all-cause mortality in a population of patients with Coronary Heart Disease(CHD) using a retrospective cohort study design.

METHODS: Data were obtained from the 1999-2018 National Health and Nutrition Examination Survey (NHANES). ALI was calculated as BMI × albumin level ÷ NLR, integrating anthropometric, nutritional, and inflammatory biomarkers. History of CHD was obtained using a questionnaire. We used Cox regression analysis to explore potential relationships and examined the nonlinear relationship using Restricted Cubic Splines (RCS).

RESULTS: A total of 1,295 participants were included in the study. Cox regression results revealed that a higher ALI was associated with lower all-cause mortality in patients with CHD. The subgroup and interaction analyses showed that the results were consistent. After adjusting for all covariates, participants in quartile 4 of ALI showed a 39% reduction in all-cause mortality compared to quartile 1. RCS analysis indicates a U-shaped relationship with a breaking point of 117.33.

CONCLUSION: In the United States, higher ALI was associated with lower all-cause mortality among patients with CHD. These findings suggest a potential association between ALI and all-cause mortality in CHD patients that warrants further investigation in prospective studies. Future interventional studies are needed to determine whether strategies targeting the components of ALI could improve clinical outcomes in this population.

The effects of self-efficacy and e-health literacy on depressive symptoms in Chinese college students: a cross-sectional survey study

BMC Psychol. 2025 Aug 31;13(1):992. doi: 10.1186/s40359-025-03189-8.

ABSTRACT

BACKGROUND: The number of college students in need of treatment for depressive symptoms far outweighs the resources of most counseling centers due to rising health needs. It is necessary to establish prevention and intervention strategies for college students. This study aimed to explore the associations between self-efficacy, e-health literacy, and depressive symptoms to guide college students in adopting preventive measures and potential interventions for managing depressive symptoms.

METHODS: This cross-sectional study randomly recruited 1500 students from two universities in Nantong City from May to December 2020. Participants’ demographic characteristics, self-efficacy, e-health literacy, and depressive symptoms were collected. The mediating effect of e-Health literacy was evaluated using the bootstrap resampling technique.

RESULTS: A total of 1388 valid questionnaires were collected. The prevalence of depressive symptoms among the sample was 50.29%. Higher self-efficacy and e-health literacy were all significantly associated with lower depressive symptoms. e-Health literacy partially mediated the association between self-efficacy and depressive symptoms, accounting for 26.6% of the total effect.

CONCLUSION: Improving self-efficacy and e-health literacy was associated with reducing depressive symptoms, with e-health literacy partially mediating the relationship between self-efficacy and depressive symptoms. Interventions for college students should focus on enhancing both self-efficacy and e-health literacy to help alleviate depressive symptoms.

Exploring the genetic intersection of dried fruit intake and breast cancer risk: a multi-trait genomic analysis with epidemiological context

J Health Popul Nutr. 2025 Aug 31;44(1):314. doi: 10.1186/s41043-025-01059-y.

ABSTRACT

BACKGROUND: Epidemiological studies have suggested that dried fruit intake may be associated with a lower risk of breast cancer (BC), yet the genetic mechanisms underlying this association remain unclear. This study aimed to explore the potential genetic relationship between dried fruit intake and BC susceptibility.

METHODS: We conducted a comprehensive genetic analysis using genome-wide association study (GWAS) data for dried fruit intake and BC, focusing on individuals of European ancestry. We assessed genome-wide and region-specific genetic correlations using several complementary methods, including linkage disequilibrium score regression and regional genetic mapping. To identify shared genetic regions, we applied statistical approaches that integrate information across traits and improve the detection of common genetic signals.

RESULTS: Modest but statistically significant negative genetic correlations were observed between dried fruit intake and BC, including its subtypes. Regional analysis revealed shared signals across multiple chromosomal regions. Five candidate loci were consistently identified as shared between the traits, including BCL11A, MAD1L1, MLLT10, JMJD1C, and RP11-795H16.2.

CONCLUSION: This study provides evidence for a genome-wide genetic link between dried fruit intake and BC risk, identifying several loci that may be shared between the traits. These findings may help improve our understanding of BC development and offer preliminary leads for future dietary prevention and personalized interventions, pending further experimental validation.

Impact of stopping Tenofovir disoproxil fumarate at various times on elevated postpartum ALT levels and breastfeeding in pregnant women with chronic hepatitis B: a prospective observational cohort study

BMC Pregnancy Childbirth. 2025 Sep 1;25(1):900. doi: 10.1186/s12884-025-08078-x.

ABSTRACT

BACKGROUND: To investigate the impact of tenofovir disoproxil fumarate (TDF) withdrawal timing on elevated postpartum alanine aminotransferase (ALT) levels and breastfeeding in pregnant women who received TDF therapy to prevent mother-to-child transmission (MTCT) of hepatitis B virus (HBV) infection.

METHODS: All enrolled women began treatment with TDF during weeks 24-32 of pregnancy and were divided into three groups that stopped TDF at delivery (Group A), at 4 weeks postpartum (Group B), or at 12 weeks postpartum (Group C). The biochemical and virological markers of hepatitis B were regularly measured and compared. Binary logistic regression analysis was used to explore the risk factors of elevated ALT levels.

RESULTS: Elevated postpartum ALT levels were observed in 91 of the 160 patients, including 38 out of 59 (64.41%) in Group A, 27 out of 51 (52.94%) in Group B, and 26 out of 50 (54%) in Group C. The incidence of elevated ALT levels did not differ significantly among the three groups (P = 0.338). Moreover, there was no significant difference in the severity of elevated ALT levels among the three groups (P = 0.558). Binary logistic regression analysis showed that ALT at delivery was an independent risk factor for elevated ALT levels (odds ratio = 1.098, 95% confidence interval, 1.039-1.160, P = 0.001). ROC analysis identified ALT ≥ 23 U/L at delivery as the optimal cutoff (AUC = 0.703, 95% CI: 0.622-0.785) for predicting elevated postpartum ALT levels. Breastfeeding rates were significantly higher in Group A (79.66%) compared to Group B (25.49%) and Group C (42%), both P values = 0.000.

CONCLUSIONS: When TDF is used to prevent MTCT of HBV, withdrawal timing did not significantly affect overall ALT elevation patterns. However, early TDF withdrawal at delivery was associated with higher breastfeeding rates, and mothers with ALT levels ≥ 23 U/L at delivery may benefit from extended postpartum antiviral therapy.

A chitosan-lignin biocomposite adsorbent for RO16 dye and Cr(VI) heavy metal removal from aqueous solutions: new interpretations via experiments and statistical physics analysis

BMC Chem. 2025 Aug 31;19(1):259. doi: 10.1186/s13065-025-01621-z.

ABSTRACT

A biocomposite composed of chitosan and lignin was synthesized for the removal of dyes and metals from aqueous solutions. The structural and surface properties of the adsorbent were characterized using FT-IR spectroscopy, SEM micrograph, X-ray diffraction, nitrogen adsorption-desorption isotherms, BJH pore size distribution, and zeta potential evolution. This study also presented a physicochemical investigation of the adsorption mechanism of reactive orange 16 (RO16) dye and hexavalent chromium (Cr(VI)) ions on chitosan-lignin biocomposite, using both experimental adsorption data and theoretical modeling based on statistical physics theory to elucidate the underlying interactions. An advanced statistical physics adsorption model, namely heterogeneous monolayer model with two functional groups (HMLM2FG), was employed to simulate the adsorption behavior, indicating that RO16 and Cr(VI) interacted with two distinct functional groups on the chitosan + 50% lignin surface. This model enabled detailed stereographic and energetic studies of the tested adsorption systems. Hence, stereographic analysis revealed that the studied adsorbent functional groups preferentially capture the attached species with n > 1 at specific temperatures, suggesting a multi-ionic mechanism with significant aggregation. The total maximum adsorbed quantities of chitosan-lignin adsorbent, determined by the proposed model HMLM2FG, were found to be 59.43-79.76 mg/g for RO16 and 52.06-72.61 mg/g for Cr(VI). Chitosan + 50% lignin demonstrated then greater efficiency in removing RO16 and Cr(VI) from aqueous solutions, showing an exothermic adsorption process characterized by adsorption energies ranging from 4.88 to 16.97 kJ/mol. These energy values were consistent with physisorption mechanisms. Overall, this study combined experimental findings with a theoretical approach to offer a novel microscopic and macroscopic analysis of the adsorption behavior of two major industrial pollutants on chitosan-lignin biocomposite.Clinical trial number: Not applicable.

Subcortical brain volume variations in autistic individuals across the lifespan

Mol Autism. 2025 Sep 1;16(1):46. doi: 10.1186/s13229-025-00673-1.

ABSTRACT

BACKGROUND: Structural alterations in subcortical brain regions-including the amygdala, hippocampus, basal ganglia, and cerebral ventricles-have been linked to various clinical features of autism spectrum disorder (ASD). However, volumetric features among these regions in autistic individuals across the lifespan remain poorly understood. This cross-sectional study aimed to investigate age-associated volumetric deviations in these clinically implicated subcortical regions of autistic individuals and neurotypical controls, and to examine the structural interrelationships within each group.

METHODS: We examined multi-site T1-weighted MRI data from 119 autistic and 122 neurotypical participants aged 7-73 years. Volumetric data for the amygdala, hippocampus, basal ganglia, and cerebral ventricles were harmonized across sites using the ComBat algorithm. Following this, volumetric composite indices (principal component scores) were extracted for each region using principal component analysis. These scores represent dominant volumetric patterns of each subcortical region, with higher values reflecting greater volume. These composite scores were then compared between groups and with increasing age.

RESULTS: Autistic participants exhibited greater amygdala volume in early life, followed by more pronounced age-associated reductions in adulthood compared to neurotypical controls. A similar trend was observed for the hippocampus, with early volumetric enlargement giving way to steeper declines in later years. In contrast, the autistic group consistently trended towards larger basal ganglia across the lifespan. Additionally, autistic participants showed accelerated enlargement in the cerebral ventricles with increasing age. Both groups exhibited patterns of inverse volumetric associations between the cerebral ventricles and surrounding subcortical regions in later adulthood; however, these relationships were more pronounced and widely distributed in the autistic group.

LIMITATIONS: The cross-sectional design of this study limited us from capturing intra-individual differences at baseline and quantifying the lifespan trajectories of each participant. Site-related sampling differences may have introduced cohort bias in the results.

CONCLUSIONS: Autistic participants and neurotypical controls exhibit distinct, age-related volumetric patterns across key subcortical brain regions. Enlargement of the cerebral ventricles and their inverse structural relationships with neighboring structures in later life may indicate atrophic processes beginning in middle adulthood in ASD. These findings highlight the need to further investigate mechanisms of atypical brain aging in ASD and consider these subcortical brain regions as potential biomarkers of neurodegeneration and intervention targets across the adult lifespan.

Perioperative lactate levels as prognostic indicators in patients undergoing early excision and grafting for extensive burns

BMC Surg. 2025 Aug 31;25(1):402. doi: 10.1186/s12893-025-03133-y.

ABSTRACT

BACKGROUND: Elevated lactate levels are reliable biomarkers of tissue hypoperfusion and metabolic stress. However, their prognostic significance in extensive burn patients undergoing early excision and grafting (EEG) remains unclear. This study aimed to evaluate the prognostic value of perioperative lactate levels in predicting clinical deterioration following EEG in patients with extensive burns.

METHODS: In this retrospective cohort study, adult burn patients with ≥ 50% total burn surface area (TBSA) or ≥ 20% full-thickness burns treated between March 2021 and September 2023 were included. Patients were categorized into Deterioration and Non-Deterioration groups based on changes in Sequential Organ Failure Assessment (SOFA) scores. Statistical analyses included univariate and multivariate logistic regression, as well as receiver-operating characteristic (ROC) curve analysis.

RESULTS: Of 82 patients, 37.8% were classified into the Deterioration Group. Compared with the Non-Deterioration Group, these patients presented with a significantly higher burn index (BI), larger surgical area, and greater intraoperative blood transfusion volumes. Temporal trends in lactate levels appeared to differ between groups: lactate levels peaked on POD1 and returned to baseline by postoperative Day 3(POD3) in the Non-Deterioration Group, whereas they remained persistently elevated in the Deterioration Group. Among all perioperative time points, lactate levels on POD3 were significantly higher in the Deterioration Group (2.88 ± 0.65 mmol/L vs. 2.27 ± 0.68 mmol/L, p < 0.001) and were independently associated with clinical deterioration clinical deterioration (OR 2.97, 95% CI 1.18-8.71, p = 0.031). POD3 lactate levels demonstrated the highest discriminatory performance for identifying postoperative deterioration (AUC = 0.761, 95% CI 0.656-0.866).

CONCLUSIONS: Among perioperative lactate levels in patients undergoing EEG for extensive burns, POD3 lactate levels were significantly associated with clinical deterioration and may serve as a useful marker to guide early risk assessment and supportive interventions.

Psychometrics of the autonomy and relatedness inventory in persons with type 2 diabetes

BMC Psychol. 2025 Aug 31;13(1):994. doi: 10.1186/s40359-025-03374-9.

ABSTRACT

BACKGROUND: Social support is essential for the self-management of type 2 diabetes mellitus (T2DM); no specific measure of the quality of social support has been designed and tested for people with T2DM. Having a validated questionnaire that is culturally and linguistically appropriate in this field would nurture research in this area and contribute to better patient health outcomes.

AIMS: This study investigated the psychometric features of the Autonomy in Relatedness Inventory (ARI) among individuals with T2DM in Jordan.

METHODOLOGY: We used a secondary dataset on self-management and outcomes of individuals with T2DM to examine the psychometric properties of the ARI. The ARI’s items’ overall reliability was assessed using internal consistency (Cronbach’s alpha). Exploratory Factor Analysis (EFA) was used to evaluate the validity of the ARI. Confirmatory factor analysis (CFA) was performed using structural equation modeling (SEM) to test the yielded factors.

RESULTS: The ARI demonstrated high reliability (Cronbach’s alpha value was 0.90) and validity in T2DM patients. Convergent validity of the ARI was established. The findings showed that ARI was strongly correlated with functional social support (r = .61, p < .001), in addition to negative correlations with depression (r= -.26, p < .001), anxiety (r= -.18, p < .001), and stress (r= -.24, p < .001). Regarding the factor structure of ARI, two latent factors were determined using a scree plot and EFA.

CONCLUSION: ARI provides a psychometrically sound method for measuring autonomy and relatedness in T2DM patients in Jordan.
