文摘BACKGROUND Visual impairment during early childhood can hinder motor,language,and social development,yet data on its developmental impact across common pediatric ocular diseases remain limited.AIM To investigate the developmental impact of low vision and blindness on children under six with common ocular diseases.METHODS This retrospective study reviewed records of new patients under six with visual impairment at Siriraj Hospital’s low vision rehabilitation center(January 2017-October 2022).We collected ocular,systemic,and developmental data;recorded visual acuity in the better-seeing eye after refractive correction;and assessed developmental domains with the DenverⅡ.Univariable and multi-variable logistic regression identified factors associated with developmental delay.RESULTS A total of 161 pediatric patients(mean age 24.9±18.9 months)were enrolled and evaluated based on their ability to fix on and follow an object or light source.Some were further assessed using the Allen picture chart and all had visual acuity worse than 1.07±0.58 LogMAR,and 83.2%were identified as having global developmental delay(GDD).The three most common ocular causes were cortical visual impairment(CVI),optic neuropathy/atrophy,and optic nerve hypoplasia.Extremely poor visual acuity(inability to fixate and follow)was significantly associated with GDD[adjusted odds ratio(AOR)41.0]and delays in all developmental domains:Gross motor(AOR 10.0),fine motor(AOR 12.8),language(AOR 5.3),and personal-social skills(AOR 13.4)(P≤0.002).Multiple disabilities,most often visual impairment with cerebral palsy,were also significantly associated with gross motor delays(AOR 7.7)and fine motor delays(AOR 4.0)(P<0.05).CVI was also related to delays in language and personal-social skills(AOR 9.1 each)(P<0.05).CONCLUSION This study underscores the developmental issues in children with visual impairment,especially those with poorer acuity,CVI,and multiple disabilities.Significant delays were observed in all domains,including GDD.A timely referral to specialists is strongly recommended.

文摘BACKGROUND Postpartum depression(PPD)represents a significant public health concern,adversely affecting both new mothers and their infants.Despite routine early screening,PPD can persist beyond the initial postpartum months,with notably high incidence rates even one year after childbirth.Persistent PPD has been associated with poor developmental outcomes in infants,highlighting the need for continued monitoring and support during this critical period.Understanding the broader impacts of persistent PPD is essential for developing effective interventions to improve maternal and infant well-being.AIM To explore the impact of persistent PPD on infant developmental behavior and maternal self-efficacy.METHODS We recruited 60 postpartum women who experienced persistent depression after childbirth in our hospital from January 2020 to December 2024 as the research subjects.The study collected basic characteristics of both infants and mothers,analyzed the self-efficacy of the mothers and the developmental behaviors of the infants,and conducted a correlation analysis to examine the relationship between postpartum persistent depression in mothers and the developmental behaviors and self-efficacy of infants.The Bootstrap method was used to verify the significance of the mediating effect.RESULTS The basic characteristics of infants and mothers show that 53.33%are male,58.33%are born via vaginal delivery,88.33%have a normal body mass index,51.67%are aged between 25 and 29 years,70%are non-agricultural workers,51.67%have a per capita household income over 4000 yuan,96.67%are full-term births,and 58.33%of the fathers are aged between 26 and 32 years.In terms of infant development behavior,the gross motor skills score is relatively low(38.44±12.15).Regarding maternal self-efficacy,the skill score(45.68±5.49)and mental activity score(46.37±3.72)are both at a low level.Correlation analysis reveals that postpartum persistent depression is significantly negatively correlated with maternal self-efficacy and infant development behavior(β=-0.439,-0.657,P<0.001),while self-efficacy is positively correlated with infant development behavior(β=0.728,P<0.001).The path coefficient and Bootstrap method test indicate that self-efficacy acts as a mediator between postpartum persistent depression and infant development behavior,accounting for 54.80%of the effect(P<0.05),while the direct effect of postpartum persistent depression on infant development behavior is 45.20%(P<0.05).CONCLUSION Persistent PPD significantly negatively impacts infant developmental outcomes,with maternal self-efficacy serving as a partial mediator.These findings suggest that interventions targeting both depressive symptoms and selfenhancement may effectively promote infant health development.

文摘Maternal health during pregnancy has a direct impact on the risk and severity of neurodevelopmental disorders(NDDs)in the offspring,especially in the case of drug exposure.However,little progress has been made to assess the risk of drug exposure during pregnancy due to ethical constraints and drug use factors.We collected and manually curated sub-pathways and pathways(sub-/pathways)and drug information to propose an analytical framework for predicting drug candidates.This framework linked sub-/pathway activity and drug response scores derived from gene transcription data and was applied to human fetal brain development and six NDDs.Further,specific and pleiotropic sub-/pathways/drugs were identified using entropy,and sex bias was analyzed in conjunction with logistic regression and random forest models.We identified 19 disorder-associated and 256 regionally pleiotropic and specific candidate drugs that targeted risk sub-/pathways in NDDs,showing temporal or spatial changes across fetal development.Moreover,5443 differential drug-sub-/pathways exhibited sex-biased differences after filling in the gender labels.A user-friendly NDDP visualization website(https://ndd-lab.shinyapps.io/NDDP)was developed to allow researchers and clinicians to access and retrieve data easily.Our framework overcame data gaps and identified numerous pleiotropic and specific candidates across six disorders and fetal developmental trajectories.This could significantly contribute to drug discovery during pregnancy and can be applied to a wide range of traits.
文摘BACKGROUND Neurodevelopmental delays encompass a wide range of conditions that impair cognitive,motor,and social functioning,often increasing the risk of psychiatric comorbidities.Children with these delays frequently present with disorders such as attention-deficit/hyperactivity disorder(ADHD),anxiety,and behavioral disturbances,which can significantly affect development and quality of life.While genetic predisposition has been linked to these comorbidities,growing evidence highlights the role of environmental factors,including prenatal and early-life stressors.However,the interaction between genetic susceptibility and environmental influences remains poorly understood.Identifying specific genetic variants,environmental risks,and their interactions is essential for early detection and targeted interventions.AIM To investigate the combined effects of genetic and environmental factors on psychiatric comorbidities in children with neurodevelopmental delays,elucidate underlying mechanisms,and inform clinical management strategies.METHODS This retrospective cohort study included 80 children with confirmed neurodevelopmental delays and 40 age-and sex-matched typically developing controls.Comprehensive clinical and psychiatric evaluations,genetic testing(chromosomal microarray analysis and targeted next-generation sequencing),and environmental exposure assessments were conducted.Statistical analyses explored associations between genetic variants and psychiatric comorbidities,environmental risk factors,and gene-environment interactions.RESULTS Children with neurodevelopmental delays exhibited significantly higher rates of psychiatric comorbidities(70.0%)compared to controls(15.0%),with ADHD(42.5%),anxiety disorders(28.8%),and behavioral disorders(23.8%)being the most common.Pathogenic genetic variants were identified in specific pathways associated with distinct psychiatric presentations:Glutamatergic signaling variants were linked to anxiety disorders(odds ratio=3.8),dopaminergic system variants to ADHD(odds ratio=4.2),and synaptic function variants to both behavioral and anxiety disorders.Environmental factors,particularly prenatal maternal stress,early childhood adversity,and family dysfunction were strong predictors of psychiatric outcomes(β=0.42).Significant gene-environment interactions were identified,indicating that environmental exposure can moderate the effects of genetic risks on psychiatric outcomes.CONCLUSION Psychiatric comorbidities in children with neurodevelopmental delays are significantly influenced by both genetic and environmental factors,with complex interactions between the two.These findings underscore the need for integrated assessments and targeted interventions addressing both biological and environmental contributors to improve outcomes in this vulnerable population.

文摘Pigs have emerged as valuable large-animal models for cardiac xenotransplantation;however,the temporal dynamics of myocardial development in this species remains insufficiently defined.This study analyzed gene expression patterns across four key developmental stages(neonatal,juvenile,sexual maturity,and adulthood)to delineate the molecular mechanisms driving porcine myocardial development.Increases in heart weight were accompanied by proportional expansion of myocardial fiber area and chamber size,reflecting coordinated structural development.Transcriptomic profiling of myocardial tissue by RNA sequencing(RNA-seq)identified 2189 differentially expressed genes(DEGs)across stage comparisons.Short time-series expression miner(STEM)analysis classified these DEGs into four major expression clusters enriched in pathways associated with myocardial development,immune responses,cell proliferation,and metabolic processes.Among 359 DEGs conserved across all developmental stages,six candidate genes were strongly associated with myocardial development.Reverse transcription-quantitative real-time polymerase chain reaction(RT-qPCR)confirmed a significant correlation between the expression of these candidate genes and myocardial development in porcine tissue.These findings establish a transcriptomic framework for porcine myocardial maturation and provide a molecular basis for advancing cardiac xenotransplantation.

文摘Research on the distribution and development of black shales in the Lianggaoshan Formation has been deficient,which has hindered exploration for lacustrine shale oil in the Sichuan Basin.Our study characterized the well logging data,core samples,outcrops,and geochemistry of black shales in the Lianggaoshan Formation in the Sichuan Basin.Our analysis focused on the lake basin evolution and the migration characteristics,paleoenvironmental features,formation mechanisms,and developmental model of the black shales.The results indicated that black shales in the Lianggaoshan Formation exhibited significant lateral migration,with an overall thickening trend from east to west.Within the 1st Member of the formation,black shale occurred as a single thick layer in the eastern region that gradually thinned toward the central region.Multiple sets of shale developed within the 2nd and 3rd members,and these had lower thicknesses than the 1st Member and migrated toward central Sichuan.Paleoproductivity and terrigenous input were the main factors controlling the deposition of black shales.A semi-humid climate influenced the deposition of black shales,bringing abundant freshwater,terrigenous debris,and nutrients into the basin.Decomposition of organic matter consumed oxygen in sediment and bottom water,causing localized oxygen deficiency in the strata.

文摘The rhizosphere bacteria play crucial roles in plant health and growth as they are involved in assimilating nutrients and resisting adverse conditions such as nutrient stress,drought,and wind erosion.Agriophyllum squarrosum(L.)Moq.is a pioneer plant used in sand fixation due to its strong resistance to drought and wind erosion.However,the bacterial community characteristics and ecological function in the rhizosphere of A.squarrosum are poorly understood.In this study,soil samples were collected from different developmental stages(seedling stage,vegetative stage,reproductive stage,and withering stage)of A.squarrosum.Illumina Miseq sequencing was used to detect differences in soil bacterial abundance.The Phylogenetic Investigation of Communities by Reconstruction of Unobserved States(PICRUSt)program was used to predict bacterial functions,and the relationships among bacteria,functional populations,and soil nutrients were examined using a heatmap analysis.The results showed that the Shannon and Sobs indices of rhizosphere bacteria were significantly higher during the reproductive stage than during the other stages.Pantoea sp.(7.03%)was the dominant genus during the seedling stage;Arthrobacter sp.was the dominant genus during the vegetative(13.94%),reproductive(7.57%),and withering(12.30%)stages.The relative abundances of Chloroflexi,Acidobacteria,and Gemmatimonadetes were significantly high during the reproductive stage.According to the PICRUSt analysis,membrane transport,signal transduction,and environmental adaptation of the bacterial functional population occurred during the seedling stage.Carbohydrate metabolism increased during the vegetative stage,while energy metabolism,lipid metabolism,and biosynthesis of other secondary metabolites of the bacterial functional population significantly increased during the reproductive stage.The abundances of bacterial communities,functional genes,and soil nutrients were synergistically altered during various developmental stages.Our findings suggest that the developmental stages of A.squarrosum play a significant role in defining the composition and structure of bacterial communities in the rhizosphere.The results will provide a basis for better prediction and understanding of soil bacterial metabolic potential and functions of A.squarrosum rhizosphere in sandy areas.

文摘Developmental venous anomalies(DVAs)are benign congenital veins that collect normal brain drainage into a single outlet.Cerebral cavernous malformations(CMs)are clusters of thin-walled capillary cavities prone to bleeding.When both lesions coexist,the DVA’s altered venous pressure and flow can promote CM formation or rupture.Detecting a DVA abutting an otherwise unexplained intracerebral hemorrhage can therefore raise suspicion of an occult CM as a likely cause,a clue which may be invaluable for daily clinical practice.The main focus of this review is to acknowledge the hallmark imaging appearances of DVAs and CMs,as well as their coexistence,explore the clinical consequences of mixed lesions,and emphasize that recognizing their partnership is vital for an accurate,timely diagnosis and appropriately targeted management.
