Global trends and hotspots of type 2 diabetes in children and adolescents:A bibliometric study and visualization analysis

BACKGROUND Epidemiological surveys indicate an increasing incidence of type 2 diabetes mellitus(T2DM)among children and adolescents worldwide.Due to rapid disease progression,severe long-term cardiorenal complications,a lack of effective treatment strategies,and substantial socioeconomic burdens,it has become an urgent public health issue that requires management and resolution.Adolescent T2DM differs from adult T2DM.Despite a significant increase in our understanding of youth-onset T2DM over the past two decades,the related review and evidence-based content remain limited.AIM To visualize the hotspots and trends in pediatric and adolescent T2DM research and to forecast their future research themes.METHODS This study utilized the terms“children”,“adolescents”,and“type 2 diabetes”,retrieving relevant articles published between 1983 and 2023 from three citation databases within the Web of Science Core Collection(SCI,SSCI,ESCI).Utilizing CiteSpace and VoSviewer software,we analyze and visually represent the annual output of literature,countries involved,and participating institutions.This allows us to predict trends in this research field.Our analysis encompasses co-cited authors,journal overlays,citation overlays,time-zone views,keyword analysis,and reference analysis,etc.RESULTS A total of 9210 articles were included,and the annual publication volume in this field showed a steady growth trend.The United States had the highest number of publications and the highest H-index.The United States also had the most research institutions and the strongest research capacity.The global hot journals were primarily diabetes professional journals but also included journals related to nutrition,endocrinology,and metabolism.Keyword analysis showed that research related to endothelial dysfunction,exposure risk,cardiac metabolic risk,changes in gut microbiota,the impact on comorbidities and outcomes,etc.,were emerging keywords.They have maintained their popularity in this field,suggesting that these areas have garnered significant research interest in recent years.CONCLUSION Pediatric and adolescent T2DM is increasingly drawing global attention,with genes,behaviors,environmental factors,and multisystemic interventions potentially emerging as future research hot spots.

Unraveling the landscape of pediatric pancreatic tumors:Insights from Japan

Pediatric pancreatic tumors,though rare,pose significant diagnostic and manage-ment challenges.The recent,22-year nationwide survey on pediatric pancreatic tumors in Japan by Makita et al offers valuable insights into this uncommon enti-ty,revealing striking geographical variations and questioning current treatment paradigms.This editorial commentary analyzes the study's key findings,inclu-ding the predominance of solid pseudopapillary neoplasms and their younger age of onset,which contrast sharply with Western data.It explores the implications for clinical practice and research,emphasizing the need for population-specific approaches to diagnosis and treatment.The revealed limited institutional expe-rience and surgical management patterns prompt a reevaluation of optimal care delivery for these complex cases,suggesting benefits of centralizing healthcare services.Furthermore,the commentary advocates for international collaborative studies to elucidate the genetic,environmental,and lifestyle factors influencing the development and progression of pediatric pancreatic tumors across diverse populations.It also outlines future directions,calling for advancements in precision medicine and innovative care delivery models to improve global patient outcomes.Unraveling Makita et al's findings within the broader landscape of pediatric oncology can stimulate further research and clinical advancements in managing pancreatic and other rare tumors in children.

Saccharomyces boulardii as a single trigger of food protein-induced enterocolitis syndrome: Seven case reports

BACKGROUND Food protein-induced enterocolitis syndrome(FPIES)is the most serious type of non-immunoglobulin E(IgE)-mediated food allergic reaction manifesting as sepsis-like symptom,which can lead to shock.Saccharomyces boulardii(S.boulardii),a probiotic prescribed frequently in clinical settings,has been reported to trigger FPIES in an infant with soy-triggered FPIES.In this report,we describe a new clinical FPIES in which S.boulardii was the sole triggering factor of acute FPIES adverse reaction in seven healthy infants.CASE SUMMARY Seven FPIES cases triggered by only S.boulardii were gathered from 2011 to the present.None of the patients had previously experienced any allergic reaction to cow’s milk,soy,or complementary food.The age of the patients was 4-10-months old,and the symptoms of FPIES developed after ingestion of S.boulardii,which is mostly prescribed for the treatment of gastroenteritis or antibiotic-associated diarrhea.All patients experienced severe repetitive vomiting 1-3 hours after S.boulardii ingestion.Extreme lethargy,marked pallor,and cyanosis were also observed.No IgE-mediated hypersensitivity developed in any patient.Diarrhea was followed by initial intense vomiting in approximately 5-10 hours after S.boulardii ingestion,and only one case showed bloody,purulent,and foul-smelling diarrhea.The patients stabilized quickly,mostly within 6 hours.Symptoms got all improved within 24 hours after discontinuation of S.boulardii.CONCLUSION S.boulardii can be the sole trigger of acute FPIES and be prescribed cautiously even in healthy children without FPIES.

Negative efficacy of antidepressants in pharmacotherapy of child and adolescent depression

Antidepressants are the main drugs used to treat depression,but they have not been shown to be effective in the treatment of child and adolescent depression.However,many adolescent depression treatment guidelines still recommend the use of antidepressants,especially specific serotonin re-uptake inhibitors.Previous studies have suggested that antidepressants have little therapeutic effect but many side effects,such as switching to mania,suicide,and non-suicidal self injury(NSSI),in the treatment of child and adolescent depression.In the process of developing guidelines,drug recommendations should not only focus on impro-ving symptoms,but they should also consider potential side effects.This review discusses the serious side effects of antidepressants,including switching to mania,suicide,and NSSI.

Labial inverse dilaceration of bilateral maxillary central incisors: A case report

BACKGROUND Dilaceration is a rare dental developmental anomaly characterized by an abrupt deviation along the longitudinal axis of the root in which an angulation forms between the root and the crown.Here,we report on dilacerated bilateral maxi-llary central incisors in mixed dentition.CASE SUMMARY A 10-year-old girl presented with a chief complaint of unerupted central incisors.An oral examination and radiography provided the basis for a diagnosis of dilaceration of the maxillary central incisors.After surgical exposure of the impacted teeth,a button with an attached chain was applied to the palatal surface of teeth 11 and 21.After 8 mo,a button was bonded to the labial surface of the crown to fix an elastic chain and move the teeth toward the maxillary arch.Finally,a fixed appliance was applied to tooth alignment to Class 1 malocclusion using a 0.019×0.025-inch nickel-titanium wire.After 3 years of follow-up,the clinical findings and radiographic assessment showed that the roots had developed with vital dental pulp and healthy periodontium,were acceptable aesthetically,and showed no resorption.CONCLUSION The rare occurrences of dilacerated bilateral maxillary central incisors can be successfully treated through surgical exposure and orthodontics.

Psychological interventions for depression in children and adolescents:A bibliometric analysis

BACKGROUND Depression has gradually become a common psychological disorder among children and adolescents.Depression in children and adolescents affects their physical and mental development.Psychotherapy is considered to be one of the main treatment options for depressed children and adolescents.However,our understanding of the global performance and progress of psychological interventions for depression in children and adolescents(PIDCA)research is limited.AIM To identify collaborative research networks in this field and explore the current research status and hotspots through bibliometrics.METHODS Articles and reviews related to PIDCA from January 2010 to April 2023 were identified from the Web of Science Core Collection database.The Charticulator website,CiteSpace and VOSviewer software were used to visualize the trends in publications and citations,the collaborative research networks(countries,institutions,and authors),and the current research status and hotspots.RESULTS Until April 16,2023,1482 publications were identified.The number of documents published each year and citations had increased rapidly in this field.The United States had the highest productivity in this field.The most prolific institution was the University of London.Pim Cuijpers was the most prolific author.In the context of research related to PIDCA,both reference co-citation analysis and keywords co-occurrence analysis identified 10 research hotspots,including thirdwave cognitive behavior therapy,short-term psychoanalytic psychotherapy,cognitive behavioral analysis system of psychotherapy,family element in psychotherapy,modular treatment,mobile-health,emotion-regulation-based transdiagnostic intervention program,dementia risk in later life,predictors of the efficacy of psychological intervention,and risks of psychological intervention.CONCLUSION This bibliometric study provides a comprehensive overview of PIDCA from 2010 to present.Psychological intervention characterized as psychological-process-focused,short,family-involved,modular,internet-based,emotionregulation-based,and personalized may benefit more young people.

Are school uniforms associated with gender inequalities in physical activity? A pooled analysis of population-level data from 135 countries/regions

Purpose:It is aimed to assess whether school uniforms are associated with population-level gender inequalities in physical activity,and whether associations differ by school level,country/region income,and assessment method.Methods:An ecological study design was employed.We collected data about global uniform practices using an online survey.We searched for country/region-level estimates of school-aged youth meeting physical activity guidelines from international surveillance studies.Study selection was conducted in duplicate using a systematic process,and a random sample of all data was checked to ensure extraction and pooling processes were accurate.We calculated absolute and relative gender inequalities in physical activity for each country.Linear regression examined associations between country/region-level uniform practices(binary yes/no exposure variable) and country/region-level gender inequalities in physical activity guideline compliance(absolute and relative inequalities).We investigated moderation by school level,stratified analyses by income group,and repeated primary analyses using device-measured data.Results:Pooling data from 135 countries/regions(n=1,089,852),we found no association between population-level uniform practices and gender inequalities in physical activity across all ages(absolute:β=-0.2;95% confidence interval(95%CI):-1.7 to 1.3,p=0.74;relative:β=0.1;95%CI:-0.1 to 0.2,p=0.51).Subgroup analysis suggested a positive association in primary school settings(absolute:β=4.3;95%CI:-0.0 to 8.6,p=0.05).Among high-income countries,absolute inequalities were significantly greater in countries/regions with uniform practices(N=37) compared to those without(N=48)(9.1(SD=3.6) vs.7.8 percentage points(SD=4.3)).Repeating analyses using device-measured data(n=32,130;N=24) did not alter our primary finding.From initial descriptive statistics,we found that in countries/regions where a maj ority of schools(>50%) reportedly use uniforms,there was lower compliance with physical activity guidelines among all genders(median:16.0%,interquartile range:13.2%-19.9%,N=103) compared to generally non-uniform countries/regions(median:19.5%,interquartile range:16.4%-23.5 %,N=32)(z=3.04,p=0.002).(N=countries,regions and studies repre sented;n=sample size or participants included).Conclusion:School uniforms are associated with greater gender inequalities in physical activity in primary school settings and in high-income countries.Our population-level findings warrant testing using individual-level data across contexts.

Changes in the Non-targeted Metabolomic Profile of Three-year-old Toddlers with Elevated Exposure to Polycyclic Aromatic Hydrocarbons

Objective To investigate changes in the urinary metabolite profiles of children exposed to polycyclic aromatic hydrocarbons(PAHs)during critical brain development and explore their potential link with the intestinal microbiota.Methods Liquid chromatography-tandem mass spectrometry was used to determine ten hydroxyl metabolites of PAHs(OH-PAHs)in 36-month-old children.Subsequently,37 children were categorized into low-and high-exposure groups based on the sum of the ten OH-PAHs.Ultra-high-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry was used to identify non-targeted metabolites in the urine samples.Furthermore,fecal flora abundance was assessed by 16S rRNA gene sequencing using Illumina MiSeq.Results The concentrations of 21 metabolites were significantly higher in the high exposure group than in the low exposure group(variable importance for projection>1,P<0.05).Most of these metabolites were positively correlated with the hydroxyl metabolites of naphthalene,fluorine,and phenanthrene(r=0.336–0.531).The identified differential metabolites primarily belonged to pathways associated with inflammation or proinflammatory states,including amino acid,lipid,and nucleotide metabolism.Additionally,these distinct metabolites were significantly associated with specific intestinal flora abundances(r=0.34–0.55),which were mainly involved in neurodevelopment.Conclusion Higher PAH exposure in young children affected metabolic homeostasis,particularly that of certain gut microbiota-derived metabolites.Further investigation is needed to explore the potential influence of PAHs on the gut microbiota and their possible association with neurodevelopmental outcomes.

Special electromyographic features in a child with paramyotonia congenita: A case report and review of literature

BACKGROUND Paramyotonia congenita(PMC)stands as a rare sodium channelopaty of skeletal muscle,initially identified by Eulenburg.The identification of PMC often relies on electromyography(EMG),a diagnostic technique.The child’s needle EMG unveiled trains of myotonic discharges with notably giant amplitudes,alongside irregular wave trains of myotonic discharges.This distinctive observation had not surfaced in earlier studies.CASE SUMMARY We report the case of a 3-year-old female child with PMC,who exhibited la-ryngeal stridor,muffled speech,myotonia from birth.Cold,exposure to cool water,crying,and physical activity exacerbated the myotonia,which was relieved in warmth,yet never normalized.Percussion myotonia was observable in bilateral biceps.Myotonia symptoms remained unchanged after potassium-rich food consumption like bananas.Hyperkalemic periodic paralysis was excluded.Cranial magnetic resonance imaging yielded normal results.Blood potassium remained within normal range,while creatine kinase showed slight elevation.Exome-wide genetic testing pinpointed a heterozygous mutation on chromosome SCN4A:c.3917G>A(p.G1306E).After a six-month mexiletine regimen,symptoms alleviated.CONCLUSION In this case revealed the two types of myotonic discharges,and had not been documented in other studies.We underscore two distinctive features:Giant-amplitude potentials and irregular waves.

Gastric IgG4-related disease mimicking a gastrointestinal stromal tumor in a child: A case report

BACKGROUND Gastric IgG4-related disease(IgG4-RD)is rarely encountered in clinical practice,and especially more so among pediatric patients.To our knowledge,this is the first report of IgG4-RD presenting as a calcifying gastric mass in a child.We describe how this entity was difficult to differentiate from a gastrointestinal stromal tumor(GIST)imaging-based approaches.Therefore,this case highlights the importance of considering IgG4-RD in the differential diagnosis of gastric tumor before performing surgical resection,especially to distinguish it from malignancy to avoid unnecessary surgery.CASE SUMMARY The patient suffered from epigastric pain for several days.Panendoscopy and computed tomography scan revealed a submucosal tumor.Differential diagnoses included GIST,leiomyoma,teratoma,and mucinous adenocarcinoma.However,laparoscopic proximal gastrectomy allowed for the definitive diagnosis of IgG4-related stomach disease.CONCLUSION We emphasize the importance of considering IgG4-RD in the differential diagnosis of gastric submucosal tumors before performing surgical resection.

Mobile health interventions for improving maternal and child health outcomes in South Africa:a systematic review

Background:Maternal and child health(MCH)remains a significant public health concern globally despite previous efforts made to improve MCH services.Initiatives such as antenatal care,postnatal care services exclusive breastfeeding,child vaccination and supplements have been rolled out to improve MCH outcomes.However,inadequate maternal healthcare,socioeconomic factors,obstetric haemorrhaging,complications of hypertension during pregnancy,lack of maternal information,poor universal health coverage and uptake of MCH services exacerbate maternal mortality and child mortality rates,especially in resource-constrained areas in many sub-Saharan African countries including South Africa.Objective:This study aimed to review mobile health(mHealth)interventions deployed to improve maternal and child health outcomes.Methods:The study adopted the Preferred Reporting Items for Systematic Reviews and Meta-Analyses model to search and retrieve relevant literature from reputable,prominent electronic databases(Google Scholar,Scopus,PubMed,Embase,CINAHL,Web of Science,etc.).A total of 26 papers were selected and analyzed.Results:The findings revealed several mHealth interventions such as MomConnect,Mobile Alliance for Maternal Action,NurseConnect,ChildConnect,CommCare,Road to Health Application and Philani Mobile Video Intervention for Exclusive Breastfeeding have been utilized by healthcare workers and women to improve access to MCH services.However,inadequate digital infrastructure,digital divide,resistance to change,inadequate funding,language barriers,short message service and data costs,lack of digital skills and support,compatibility,scalability and interoperability issues,legislative and policy compliance,lack of mHealth awareness,data security and privacy concerns hinder uptake and utilisation of mHealth interventions.There is a need to scale up and sustain mHealth interventions and update existing regulatory framework,policies and strategies.Conclusion:mHealth interventions offer unprecedented opportunities to improve access to maternal information and substantially improve maternal and child health services.Stakeholder engagement and the development of sustainable funding strategies are important for successfully implementing and scaling mHealth projects while addressing existing and emerging key issues.

Comparative study on emotional behavior and parental job stress of only-child and non-only-child preschool children

BACKGROUND Studies have revealed that Children's psychological,behavioral,and emotional problems are easily influenced by the family environment.In recent years,the family structure in China has undergone significant changes,with more families having two or three children.AIM To explore the relationship between emotional behavior and parental job stress in only preschool and non-only preschool children.METHODS Children aged 3-6 in kindergartens in four main urban areas of Shijiazhuang were selected by stratified sampling for a questionnaire and divided into only and nononly child groups.Their emotional behaviors and parental pressure were compared.Only and non-only children were paired in a 1:1 ratio by class and age(difference less than or equal to 6 months),and the matched data were compared.The relationship between children's emotional behavior and parents'job stress before and after matching was analyzed.RESULTS Before matching,the mother's occupation,children's personality characteristics,and children's rearing patterns differed between the groups(P<0.05).After matching 550 pairs,differences in the children's parenting styles remained.There were significant differences in children's gender and parents'attitudes toward children between the two groups.The Strengths and Difficulties Questionnaire(SDQ)scores of children in the only child group and the Parenting Stress Index-Short Form(PSI-SF)scores of parents were significantly lower than those in the non-only child group(P<0.05).Pearson’s correlation analysis showed that after matching,there was a positive correlation between children's parenting style and parents'attitudes toward their children(r=0.096,P<0.01),and the PSI-SF score was positively correlated with children's gender,parents'attitudes toward their children,and SDQ scores(r=0.077,0.193,0.172,0.222).CONCLUSION Preschool children's emotional behavior and parental pressure were significantly higher in multi-child families.Parental pressure in differently structured families was associated with many factors,and preschool children's emotional behavior was positively correlated with parental pressure.

干密度对黄土渗透系数的影响

非饱和渗透系数是研究非饱和土入渗规律的重要参数,同时也是研究边坡失稳和地基浸湿变形的重要基础。本文采用变水头法测量原状黄土和重塑黄土饱和渗透系数,基于Childs&Collis-Geroge模型,结合土水特征曲线和饱和渗透系数,详细探讨了原状黄土、不同干密度非饱和重塑黄土体积含水率与渗透系数的关系和规律。结果表明,原状黄土的饱和渗透系数远小于重塑样,重塑土样饱和渗透系数随着干密度的增大而减小;黄土非饱和渗透系数减小趋势随着干密度增大而减小,但在残余含水率附近,不同干密度下试样的渗透性基本相同。

The Relationship between Parental Stress and Child Conformity:The Mediating Role of Resilience

Background:In today’s society,parental stress has become a prevalent and significant issue,impacting not only parents’mental health but also potentially profoundly affecting children’s growth and education.This topic has garnered continuous attention from scholars.The present study aims to delve into the relationship between parental stress and children’s behavior,particularly focusing on children’s conformity and discipline development during crucial stages.This study aims to explore the relationship between parental stress,child conformity,and resilience,and further examines the mediating role of resilience in the relationship between parental stress and child conformity.Methods:We used three scales:the Parental Stress Scale,the Child Conformity Scale,and the Resilience Scale,to survey 890 elementary school students(aged 6–12)and their parents in the Beijing-Tianjin-Hebei region of China.We employed SPSS 26.0 software for data analysis,conducting descriptive statistics,correlation analysis,and mediation effect tests sequentially.In the mediation effect tests,we utilized structural equation modeling(SEM)and regression analysis to examine the mediation effects,ensuring the accuracy and scientific nature of our analysis.Results:Through descriptive statistics,correlation analysis,regression models,and mediation effect tests,we found that parental stress significantly negatively predicts child conformity,while resilience shows a significant positive prediction.Further mediation analysis indicates that resilience plays a partial mediating role between parental stress and child conformity,with the mediation effect accounting for 36.67%.Conclusion:These findings highlight the importance of the family environment on child behavior and provide valuable insights and recommendations for family education practices in the Beijing-Tianjin-Hebei region.Therefore,we suggest future research should further explore the complex relationships among parental stress,child conformity,and resilience,and examine regional differences to better promote children’s overall development.

Relationship between Authoritative Parenting Style and Preschool Children’s Emotion Regulation:A Moderated Mediation Model

An authoritative parenting style has been shown to promote children’s emotion regulation in European-American family studies.However,little is known about how sleep problems and the child’s sibling status in Chinese families affect this relationship.Based on family system theory,this study attempts to better understand the relationship between authoritative parenting style and emotion regulation.Mothers of preschool children in Chinese kindergartens completed questionnaires about their children’s sleep habits,their authoritative parenting styles,and children’s emotion regulation.A total of 531 children participated in this study.Results showed that authoritative parenting was positively associated with emotional regulation.Sleep problems mediated the effects of authoritative parenting style on emotion regulation.The child’s sibling status moderated the mediating effects of sleep problems in authoritative parenting and emotion regulation relationships.Specifically,the relationship between the authoritative parenting style and sleep problems was significant for only children,while birth order had no significant influence on the authoritative parenting style and sleep problems in two-child families.These findings suggest that a lowauthoritative parenting style predicts low emotion regulation through sleep problems,and this depends on the child’s sibling status,indicating that children without siblings may impair emotion regulation due to increased sleep problems.
