Spatial analysis of anemia prevalence in early childhood in Northeastern Thailand, 2020–2022

ABSTRACT Anemia poses a significant health challenge for Thai children, yet data on its geographic distribution among those aged 6–12 months is limited. This study investigates spatial variations in anemia prevalence across northeastern Thailand using 2020–2022 national data. Global and local Moran’s I analyses identified significant, nonrandom patterns, with hotspots in central and northeastern regions and coldspots in the southeast. Visualization maps highlight provincial variations, emphasizing the need for targeted interventions. These results provide critical insights for policymakers to allocate health resources effectively and develop strategic anemia intervention programs.

The Relationship Between Asthma and Food Allergies in Children.

Asthma and food allergy are two complex allergic diseases with an increasing prevalence in childhood. They share risk factors, including atopic family history, atopic dermatitis, allergen sensitization, and T2 inflammatory pathways. Several studies have shown that in children with a food allergy, the risk of developing asthma, particularly in early childhood, is high. Food allergen intake or the inhalation of aerosolized allergens can induce respiratory symptoms such as bronchospasm. Patients with both conditions have an increased risk of severe asthma exacerbations, hospitalization, and mortality. The current management of clinical food hypersensitivity primarily involves the dietary avoidance of food allergens and the use of self-injectable adrenaline for severe reactions. Poorly controlled asthma limits the prescription of oral immunotherapy to foods, which has emerged as an alternative therapy for managing food allergies. Biological therapies that are effective in severe asthma have been explored for treating food allergies. Omalizumab improves asthma control and, either alone or in combination with oral immunotherapy, increases the threshold of allergen tolerance. Understanding the interplay between asthma and food allergy is crucial for developing successful treatment approaches and ameliorating patient results.

CD26 Is Differentially Expressed throughout the Life Cycle of Infantile Hemangiomas and Characterizes the Proliferative Phase.

Infantile hemangiomas (IHs) are benign vascular neoplasms of childhood (prevalence 5-10%) due to the abnormal proliferation of endothelial cells. IHs are characterized by a peculiar natural life cycle enclosing three phases: proliferative (≤12 months), involuting (≥13 months), and involuted (up to 4-7 years). The mechanisms underlying this neoplastic disease still remain uncovered. Twenty-seven IH tissue specimens (15 proliferative and 12 involuting) were subjected to hematoxylin and eosin staining and a panel of diagnostic markers by immunohistochemistry. WT1, nestin, CD133, and CD26 were also analyzed. Moreover, CD31pos/CD26pos proliferative hemangioma-derived endothelial cells (Hem-ECs) were freshly isolated, exposed to vildagliptin (a DPP-IV/CD26 inhibitor), and tested for cell survival and proliferation by MTT assay, FACS analysis, and Western blot assay. All IHs displayed positive CD31, GLUT1, WT1, and nestin immunostaining but were negative for D2-40. Increased endothelial cell proliferation in IH samples was documented by ki67 labeling. All endothelia of proliferative IHs were positive for CD26 (100%), while only 10 expressed CD133 (66.6%). Surprisingly, seven involuting IH samples (58.3%) exhibited coexisting proliferative and involuting aspects in the same hemangiomatous lesion. Importantly, proliferative areas were characterized by CD26 immunolabeling, at variance from involuting sites that were always CD26 negative. Finally, in vitro DPP-IV pharmacological inhibition by vildagliptin significantly reduced Hem-ECs proliferation through the modulation of ki67 and induced cell cycle arrest associated with the upregulation of p21 protein expression. Taken together, our findings suggest that CD26 might represent a reliable biomarker to detect proliferative sites and unveil non-regressive IHs after a 12-month life cycle.

Prevalence and factors associated with undocumented children under-five in Haiti

BackgroundDespite many efforts to provide children with legal existence over the last decades, 1 in 4 children under the age of 5 (166 million) do not officially exist, with limited possibility to enjoy their human rights. In Latin America and the Caribbean, Haiti has one of the highest rates of undocumented births. This study aimed to analyze the prevalence and the determinant factors of undocumented childhood in Haiti.MethodsFor analysis of undocumented childhood and related socioeconomic determinants, data from the 2016/17 Haiti demographic and health survey were used. The prevalence and the associated factors were analyzed using descriptive statistics and the binary logistic regression model.ResultsThe prevalence of undocumented childhood in Haiti was 23% (95% CI: 21.9–24.0) among children under-five. Among the drivers of undocumented births, mothers with no formal education (aOR = 3.88; 95% CI 2.21–6.81), children aged less than 1 year (aOR = 20.47; 95% CI 16.83–24.89), children adopted or in foster care (aOR = 2.66; 95% CI 1.67–4.24), children from the poorest regions like “Artibonite” (aOR = 2.19; 95% CI 1.63–2.94) or “Centre” (aOR = 1.51; 95% CI 1.09–2.10) or “Nord-Ouest” (aOR = 1.61; 95% CI 1.11–2.34), children from poorest households (aOR = 6.25; 95% CI 4.37–8.93), and children whose mothers were dead (aOR = 2.45; 95% CI 1.33–4.49) had higher odds to be undocumented.ConclusionAccording to our findings, there is an institutional necessity to bring birth documentation to underprivileged households, particularly those in the poorest regions where socioeconomic development programs are also needed. Interventions should focus on uneducated mothers who are reknown for giving birth outside of medical facilities. Therefore, an awareness campaign should be implemented to influence the children late-registering behavior.

Critical menarche age for late-life dementia and the role of education and socioeconomic status

ABSTRACT Estrogen exposure during menstrual years has been associated with late-life neuroprotection. We explored the presence of an age-sensitive menarche window for cognition in old age and the impact of socioeconomic status and education. We compared neuropsychological performance of 1082 older women [MeanAGE = 72.69 (5.48)] with menarche in childhood, early-, mid-, and late-adolescence and dementia prevalence, severity, and type, including the effects of education and socioeconomic status. Adjusting for covariates, menarche at 11–14 years of age was associated with better memory, executive and global cognitive functioning in old age, and stronger positive effects of education and socioeconomic status on cognition than those with menarche at 15–17 years. We found a critical age window for the neuroprotective effects of estrogens during early adolescence, putting women with later menarche at higher risk for cognitive decline. Effects of socioeconomic status and education in adulthood should be a focus of future research.

Paediatric post-grommets surgery review: Audiology-led clinic

BackgroundOtitis media (OM) has a high prevalence in childhood, and grommet insertion is the most common surgical treatment for OM. The public health system in Australia faces considerable strains, including high demand for Ear, Nose and Throat (ENT) specialists. Extending the scope of practice for audiologists to manage post-operative care for children receiving grommets has the potential to alleviate this burden. MethodsThis non-randomised, cross-sectional study investigated the efficacy and feasibility of an audiology-led clinic for managing paediatric patients after grommet insertion at a tertiary teaching hospital in Western Australia. Senior audiologists reviewed children at 6 weeks and 10 months post-operatively, escalating care to an ENT specialist if abnormalities were observed. Children with normal hearing and patent grommets were reviewed and discharged by the audiologist. ResultsA total of 93 children were included (mean age 5.18 ± 2.25 years, range 1.59–11.46 years). At the 6-week review, 72/93 (77 %) presented with in-situ grommets and normal hearing, while 21/93 (22 %) were escalated for immediate ENT care. At the 10-month review, 54/72 (75 %) were discharged without further ENT intervention, and 18/72 (25 %) required additional ENT investigation. ConclusionThis study demonstrated that an audiology-led follow-up clinic for post-grommet insertion is a viable option, providing efficient, high-quality care. Two-thirds of paediatric patients did not require ENT input or review post-operatively. The results support interdisciplinary models of care, which could help address challenges faced by overburdened ENT services.

What is the disease burden from childhood and adolescent obesity?: a narrative review.

The prevalence of childhood and adolescent obesity has increased and exacerbated during the coronavirus disease 2019 pandemic, both in Korea and globally. Childhood and adolescent obesity poses significant risks for premature morbidity and mortality. The development of serious comorbidities depends not only on the duration of obesity but also on the age of onset. Obesity in children and adolescents affects almost all organ systems, including the endocrine, cardiovascular, gastrointestinal, reproductive, nervous, and immune systems. Obesity in children and adolescents affects growth, cognitive function, and psychosocial interactions during development, in addition to aggravating known adult comorbidities such as type 2 diabetes mellitus, hypertension, dyslipidemia, nonalcoholic fatty liver disease, obstructive sleep apnea, and cancer. Childhood and adolescent obesity are highly associated with increased cardiometabolic risk factors and prevalence of metabolic syndrome. The risk of cardiovascular and metabolic diseases in later life can be considerably decreased by even a small weight loss before the onset of puberty. Childhood and adolescent obesity is a disease that requires treatment and is associated with many comorbidities and disease burdens. Therefore, early detection and therapeutic intervention are crucial.

Prevalence of Thyroid Nodules in Residents of Ukraine Exposed as Children or Adolescents to Iodine-131 from the Chornobyl Accident.

Background: Although childhood exposure to radioactive iodine-131 (I-131) is an established risk factor for thyroid cancer, evidence for an association with thyroid nodules is less clear. The objective of this study is to evaluate the association between childhood I-131 exposure and prevalence of ultrasound-detected thyroid nodules overall and by nodule histology/cytology (neoplastic/suspicious/non-neoplastic), size (<10 mm/≥10 mm), and number (single/multiple). Methods: This is a cross-sectional study of radiation dose (mean = 0.53 gray, range: 0.0003-31 gray) and screen-detected thyroid nodules conducted in 1998-2000 (median population age 21.5 years) in a cohort of 13,243 residents of Ukraine who were under 18 years at the time of the Chornobyl accident on April 26, 1986. Excess odds ratios per gray (excess odds ratio [EOR]/Gy) and confidence intervals (CIs) were estimated using logistic regression. Results: Among 13,078 eligible individuals, we identified 358 (2.7%) with at least one thyroid nodule. Significantly increased dose-response associations were found for all nodules and nodule groups with doses <5 Gy except individuals with non-neoplastic nodules. Among individuals with doses <5 Gy, the EOR/Gy for neoplastic nodules (5.35; CI: 2.19-15.5) was significantly higher than for non-neoplastic nodules (0.24; CI: 0.07-0.74), but the EOR/Gy did not vary by nodule size or number. Conclusions: Childhood exposure to I-131 is associated with an increased risk of thyroid nodules detected 12-14 years following exposure, and the risk for neoplastic nodules is higher than for non-neoplastic nodules. Analyses of incident thyroid nodules may help clarify dose-response patterns by nodule characteristics and provide insights into thyroid nodule etiology.

A hypothetical intervention to reduce inequities in anxiety for Multiracial people: simulating an intervention on childhood adversity.

Multiracial people report higher mean Adverse Childhood Experiences (ACEs) scores and prevalence of anxiety than other racial groups. Studies using statistical interactions to estimate racial differences in ACEs-anxiety associations do not show stronger associations for Multiracial people. Using data from Waves 1 (1995-97) through 4 (2008-09) of the National Longitudinal Study of Adolescent to Adult Health (Add Health), we simulated a stochastic intervention over 1,000 resampled datasets to estimate the race-specific cases averted per 1,000 of anxiety if all racial groups had the same exposure distribution of ACEs as Whites. Simulated cases averted were greatest for the Multiracial group, (median = -4.17 cases per 1,000, 95% CI: -7.42, -1.86). The model also predicted smaller risk reductions for Black participants (-0.76, 95% CI: -1.53, -0.19). CIs around estimates for other racial groups included the null. An intervention to reduce racial disparities in exposure to ACEs could help reduce the inequitable burden of anxiety on the Multiracial population. Stochastic methods support consequentialist approaches to racial health equity, and can encourage greater dialogue between public health researchers, policymakers, and practitioners.

Cancer Prevalence in Children with Inborn Errors of Immunity: Report from a Single Institution.

Inborn Errors of Immunity (IEI) comprise several genetic anomalies that affect different components of the innate and adaptive responses, predisposing to infectious diseases, autoimmunity and malignancy. Different studies, mostly in adults, have reported a higher prevalence of cancer in IEI patients. However, in part due to the rarity of most of these IEI subtypes (classified in ten categories by the Primary Immunodeficiency Committee of the International Union of Immunological Societies), it is difficult to assess the risk in a large number of patients, especially during childhood. To document the cancer prevalence in a pediatric cohort from a single referral institution, assessing their risk, together with the type of neoplasia within each IEI subgroup. An extensive review of clinical records from 1989 to 2022 of IEI patients who at some point developed cancer before the age of sixteen. Of a total of 1642 patients with IEI diagnosis, 34 developed cancer before 16years of age, showing a prevalence (2.1%) significantly higher than that of the general age matched population (0.22). Hematologic neoplasms (mostly lymphomas) were the most frequent malignancies. This study represents one of the few reports focused exclusively in pediatric IEI cases, describing not only the increased risk of developing malignancy compared with the age matched general population (a fact that must be taken into account by immunologists during follow-up) but also the association of the different neoplasms with particular IEI subtypes, thus disclosing the possible mechanisms involved.

Current Challenges in Pediatric Asthma.

Asthma is a chronic lung disease characterized by reversible bronchoconstriction and inflammation of the bronchi. Its increasing prevalence in childhood as well as different triggers make asthma a challenging disease in several ways: defining its phenotype/endotype, the diagnostic approach (especially in younger children), therapeutic options, and systematic follow-up. Considering these problems, this review approaches the current status and limitations of guidelines used for asthma management in children. It also emphasizes the key points which could lead to a better understanding and the direction to take in future studies.

Spatial prevalence and associated risk factors of childhood diarrhea: A cross-sectional study in rural Indian context

Diarrheal disease is the most prevalent health issue among children under the age of five, contributing to a staggering toll of approximately 525,000 deaths worldwide each year. Despite its devastating consequences, it is essential to note that this disease is both preventable and treatable. The present study aims to investigate the prevalence of childhood (under 5 years) diarrheal disease in rural parts of India and identify relevant factors associated with diarrheal disease, encompassing maternal, household, environmental, and individual-level characteristics. In addition, the study highlights the spatial distribution of diarrheal disease across India, identifying hot-spot and cold-spot regions, along with the associated risk factors. The study utilized secondary data extracted from the fifth round of the National Family Health Survey, conducted in India between 2019 and 2021 (N=161,368). Binary logistic regression analysis and spatial clustering techniques, specifically utilizing Global Moran&amp;rsquo;s I, were employed to achieve the study&amp;rsquo;s objectives. The findings revealed that diarrhea cases are more prevalent among the poor, rural, and children of Muslim families, as well as among those residing in environments lacking hygienic or adequate sanitation facilities and in households without floors, walls, or roofs built with concrete material. The highest prevalence is observed in the eastern and western parts of India. Necessary interventions are required to reduce diarrhea cases among children under the age of five in rural Indian areas. Given the vector-borne nature of this disease, public awareness of the importance of maintaining fresh and clean drinking water facilities is imperative.

Suggestions for the management of pediatric obesity in Korea

Background: The prevalence of pediatric obesity has increased both globally and in South Korea over the past few decades, and obesity in childhood and adolescence is a serious public health concern.Current Concepts: The increasing prevalence of childhood and adolescent obesity is associated with an increase in comorbidities, such as type 2 diabetes mellitus, hypertension, nonalcoholic fatty liver disease, and dyslipidemia, which were previously observed in adults. Furthermore, pediatric obesity contributes to increased medical costs. Recent studies have reported an increase in the prevalence of severe obesity.Discussion and Conclusion: It is important to acknowledge the need for obesity management and responsive management capabilities in children and adolescents. Prevention of obesity in all children, screening for comorbidities in high-risk children, and establishment of treatment strategies are important measures. Pediatric obesity can be addressed by approaching it from a social perspective, providing a National Health Insurance System, and facilitating multidisciplinary collaboration between experts from various fields.

Prevalence of early childhood caries post covid-19 pandemic in Mumbai among children aged 3-5 years: A cross-sectional pilot study

This cross-sectional pilot study aims to investigate the prevalence of Early Childhood Caries (ECC) among children aged 3 to 5 years in Mumbai City, Maharashtra, following the COVID-19 pandemic. A total of 91 children were included in the study, with ECC prevalence assessed through standardized examinations and dmfs scoring. Simple random sampling was employed, and data were analyzed using descriptive statistics and inferential tests. The study found a high prevalence of ECC (63.74%) among the study population, with no significant gender-based differences observed in ECC occurrence or severity. Despite similar ECC prevalence rates between boys and girls, the overall burden of ECC underscores the urgent need for targeted interventions and preventive measures. The findings highlight the pressing oral health challenge faced by young children in urban settings post-pandemic and emphasize the importance of comprehensive oral health promotion programs and equitable access to preventive oral healthcare. Addressing modifiable risk factors and integrating oral health services into primary healthcare systems are essential steps toward improving oral health outcomes for children in Mumbai and similar urban environments.

Distinct T cell signatures are associated with Staphylococcus aureus skin infection in pediatric atopic dermatitis.

Atopic dermatitis (AD) is an inflammatory skin condition with a childhood prevalence of up to 25%. Microbial dysbiosis is characteristic of AD, with Staphylococcus aureus the most frequent pathogen associated with disease flares and increasingly implicated in disease pathogenesis. Therapeutics to mitigate the effects of S. aureus have had limited efficacy and S. aureus-associated temporal disease flares are synonymous with AD. An alternative approach is an anti-S. aureus vaccine, tailored to AD. Experimental vaccines have highlighted the importance of T cells in conferring protective anti-S. aureus responses; however, correlates of T cell immunity against S. aureus in AD have not been identified. We identify a systemic and cutaneous immunological signature associated with S. aureus skin infection (ADS.aureus) in a pediatric AD cohort, using a combined Bayesian multinomial analysis. ADS.aureus was most highly associated with elevated cutaneous chemokines IP10 and TARC, which preferentially direct Th1 and Th2 cells to skin. Systemic CD4+ and CD8+ T cells, except for Th2 cells, were suppressed in ADS.aureus, particularly circulating Th1, memory IL-10+ T cells, and skin-homing memory Th17 cells. Systemic γδ T cell expansion in ADS.aureus was also observed. This study suggests that augmentation of protective T cell subsets is a potential therapeutic strategy in the management of S. aureus in AD.

Unsafe child feces disposal and childhood wasting among under five children in Myanmar

Background: Wasting is a major public health problem among under five children in developing countries, including Myanmar. The distribution of wasting and its associated factors are not well known in Myanmar. Objectives: This study aimed to examine the wasting prevalence and identify the association between child feces disposal and wasting among under-five children in Myanmar. Methods: A cross-sectional study was conducted on 1,207 under five children in Myanmar from September to December 2022. This study employed a multistage random sampling method with structured questionnaires and anthropometric measures. The World Health Organization's (WHO) definition and growth standards were used to determine the wasting. Multivariable logistic regression was performed to identify the association. An adjusted odds ratio with a 95% confidence interval and a p-value &lt;0.05 was used to define statistical significance. Results: The prevalence of childhood wasting among under five children in Myanmar was 11.10% (95% CI: 9.45 to 13.00). This study revealed that children from unsafe child feces disposing families were 94 % more likely to be wasted (AOR=1.94, 95% CI: 1.22 to 3.09; p-value 0.005). Other covariates to childhood wasting were water shortage (AOR=2.17, 95% CI: 1.13 to 4.16; p-value 0.02), less than four handwashing steps of mother (AOR=3.20, 95% CI: 1.93 to 5.32; p-value &lt;0.001), located in hilly region (AOR=2.27, 95% CI: 1.53 to 3.37; p-value &lt;0.001), boys (AOR=2.80, 95% CI: 1.86 to 4.23; p-value &lt;0.001), birth interval less than 3 years (AOR=1.84, 95% CI: 1.10 to 3.11; p-value 0.02), and eating more than 4 times per day (AOR=3.19, 95% CI: 1.93 to 5.27; p-value &lt;0.001). Conclusion: This study showed a high prevalence of wasting among under five children in Myanmar. Improving the safe child feces disposal practices of mothers would be a critical intervention to reduce under five children's wasting.

DeepHealthNet: Adolescent Obesity Prediction System Based on a Deep Learning Framework.

The global prevalence of childhood and adolescent obesity is a major concern due to its association with chronic diseases and long-term health risks. Artificial intelligence technology has been identified as a potential solution to accurately predict obesity rates and provide personalized feedback to adolescents. This study highlights the importance of early identification and prevention of obesity-related health issues. To develop effective algorithms for the prediction of obesity rates and provide personalized feedback, factors such as height, weight, waist circumference, calorie intake, physical activity levels, and other relevant health information must be taken into account. Therefore, by collecting health datasets from 321 adolescents who participated in Would You Do It! application, we proposed an adolescent obesity prediction system that provides personalized predictions and assists individuals in making informed health decisions. Our proposed deep learning framework, DeepHealthNet, effectively trains the model using data augmentation techniques, even when daily health data are limited, resulting in improved prediction accuracy (acc: 0.8842). Additionally, the study revealed variations in the prediction of the obesity rate between boys (acc: 0.9320) and girls (acc: 0.9163), allowing the identification of disparities and the determination of the optimal time to provide feedback. Statistical analysis revealed that the performance of the proposed deep learning framework was more statistically significant (p 0.001) compared to the other general models. The proposed system has the potential to effectively address childhood and adolescent obesity.

Carriage of third-generation cephalosporin-resistant and carbapenem-resistant Enterobacterales among children in sub-Saharan Africa: a systematic review and meta-analysis

The increasing resistance of Enterobacterales to third-generation cephalosporins and carbapenems in sub-Saharan Africa (SSA) is a major public health concern. We did a systematic review and meta-analysis of studies to estimate the carriage prevalence of Enterobacterales not susceptible to third-generation cephalosporins or carbapenems among paediatric populations in SSA. We performed a systematic literature review and meta-analysis of cross-sectional and cohort studies to estimate the prevalence of childhood (0-18 years old) carriage of extended-spectrum cephalosporin-resistant Enterobacterales (ESCR-E) or carbapenem-resistant Enterobacterales (CRE) in SSA. Medline, EMBASE and the Cochrane Library were searched for studies published from 1 January 2005 to 1 June 2022. Studies with <10 occurrences per bacteria, case reports, and meta-analyses were excluded. Quality and risk of bias were assessed using the Newcastle-Ottawa scale. Meta-analyses of prevalences and odds ratios were calculated using generalised linear mixed-effects models. Heterogeneity was assessed using I2 statistics. The protocol is available on PROSPERO (CRD42021260157). Of 1111 studies examined, 40 met our inclusion criteria, reporting on the carriage prevalence of Enterobacterales in 9408 children. The pooled carriage prevalence of ESCR-E was 32.2% (95% CI: 25.2%-40.2%). Between-study heterogeneity was high (I2=96%). The main sources of bias pertained to participant selection and the heterogeneity of the microbiological specimens. Carriage proportions were higher among sick children than healthy ones (35.7% vs 16.9%). The pooled proportion of nosocomial acquisition was 53.8% (95% CI: 32.1%-74.1%) among the 922 children without ESCR-E carriage at hospital admission. The pooled odds ratio of ESCR-E carriage after antibiotic treatment within the previous 3 months was 3.20 (95% CI: 2.10-4.88). The proportion of pooled carbapenem-resistant for Enterobacterales was 3.6% (95% CI: 0.7%-16.4%). This study suggests that ESCR-E carriage among children in SSA is frequent. Microbiology capacity and infection control must be scaled-up to reduce the spread of those multidrug-resistant microorganisms. There was no funding source for this study.
