Education and employment outcomes in pediatric chronic kidney disease.

As outcomes and survival for children with chronic kidney disease (CKD) have improved over the last 30years, there is an emerging need to characterize and understand later educational and employment outcomes across the spectrum of pediatric CKD severity-ranging from mild CKD to requirement for dialysis and kidney transplantation. Although large-scale research on the topic of long-term educational and employment outcomes in the pediatric CKD population is relatively scarce, the existing literature does support that children across the spectrum of CKD severity are at risk for education-related difficulties including chronic school absenteeism. These education-related difficulties are compounded by well-described neurocognitive deficits-particularly in the domain of executive functioning-that may potentially perpetuate the risk for academic underachievement. This is particularly concerning given that data from the general pediatric population suggest that childhood academic underachievement is associated with higher likelihood of un-/underemployment in adulthood. This review highlights what is known about educational and employment outcomes among persons with a history of childhood CKD, as well as suggestions for interventions to improve educational outcomes for this population.

The Impact of Undernutrition and Anemia on HIV-Related Mortality Among Children on ART in Sub-Saharan Africa: A Systematic Review and Meta-Analysis.

Although there have been significant advancements in providing HIV-infected children with access to antiretroviral therapy (ART), the mortality rates have remained unacceptably high. Inadequate nutrient intake or absorption is a widespread problem in several African nations, resulting in undernutrition and anemia. However, the pooled effect of malnutrition and anemia on HIV-related death related to children receiving ART was not investigated in sub-Saharan Africa. We searched multiple electronic databases (PubMed/MEDLINE, Embase, CINAHL, and Web of Science) for observational studies published between January 1, 2010, and April 24, 2024 that reported the risk factors or effects of undernutrition and, anemia on HIV-related mortality among children. Study selection, data extraction, and quality evaluation were carried out separately by two reviewers. A meta-analysis was conducted using random effect models. The review included 27 studies with a combined total of 61,796 study participants. The study findings showed that severe wasting (HR: 2.49; 95% CI: 1.87-3.30), being underweight (HR: 2.11; 95% CI: 1.64-2.72), and Anemia (HR: 2.58; 95% CI: 2.08-3.19) were highly linked to HIV-related death among children. The risk of death due to anemia was greater among children under the age of 5 years than older children. Undernutrition and anemia in sub-Saharan African children increased the risk of HIV-related death. The impact of malnutrition and anemia among under 5 years old children with HIV/AIDS was more pronounced, suggesting that these conditions at this early age can have more serious consequences for a child's survival. The importance of combining nutrition with HIV treatment programs in sub-Saharan African countries is crucial.

Burden of acute malnutrition in the conflict-affected urban communities of Tigray, Northern Ethiopia: a cross-sectional study

BackgroundMalnutrition impedes the growth, development, and survival of children. Conflict has severely affected the livelihoods of families and caused an alarming increase in food insecurity, population displacements, and extreme poverty in Tigray. Therefore, this study aimed to assess the prevalence and factors associated with acute malnutrition among 6- to 23-month-old children in the armed conflict-affected urban areas of Tigray.MethodsThe study population were randomly selected children aged 6 to 23 months. A cross-sectional study design was used. Data was collected from July 13 to 28, 2022 in Tigray region, Northern Ethiopia. A systematic random sampling technique was used to select the participants. Sociodemographic, lifestyle, anthropometric, and clinical variables were collected using a structured questionnaire. The data were analyzed using SPSS version 24 and presented using descriptive and analytical statistics. Binary logistic regression was used to identify independent predictors of acute malnutrition. All variables were declared statistically significant at a p-value of < 0.05.ResultsA total of 368 participants aged 6–23 months were included in the study. Half (50.5%) and around three-fourths (72.6%) of the participants were females and 12 to 23 months old children, respectively, with a mean (SD) age of 15.2 (5.1) months. The overall proxy global acute malnutrition rate was 44.3%, with 34.5% and 9.8% being moderate acute malnutrition and severe acute malnutrition, respectively. In the multivariable logistic regression model, three variables (consumption of legumes, maternal nutritional status, and household access to clean water) were identified as significant predictors of proxy global acute malnutrition. Children who didn’t eat legumes (AOR (95%CI): 2.39 (1.44, 3.97)), children of acutely malnourished mothers (AOR (95%CI): 1.60 (1.02, 2.51)), and children from households with insufficient water supply (AOR (95%CI): 1.99 (1.20, 3.31)) were significantly associated with an increased likelihood of acute malnutrition as compared with their counterparts.ConclusionsChildren from the armed conflict areas of Tigray are disproportionally impacted by acute malnutrition. Nearly half of the children were acutely malnourished, with one in ten suffering from the more serious severe acute malnutrition. Hence, urgent action is needed to prevent their permanent mental and physical deterioration and death by improving consumption of high protein foods, nutritional status of mothers, and access to clean water.

Sexual dysfunction among long-term survivors of Hodgkin lymphoma.

Survival rates from childhood cancer continue to increase, with an ongoing interest in long-term survivorship. Although infertility and gonadal failure are well recognized in Hodgkin lymphoma (HL) survivors, sexual dysfunction is less studied. The objective of this study was to compare the prevalence of sexual dysfunction in HL survivors with that in matched community controls. Long-term survivors of HL (n=186; female, 51.61%; mean age at diagnosis. 14.41 years [range, 3.01-22.60 years]; current mean±standard deviation age, 36.73±7.93 years) and matched community controls (n=182; female, 50.55%; mean±standard deviation age, 36.41±9.02 years) completed a comprehensive, in-person clinical assessment, laboratory battery, and the International Index of Erectile Function or the Female Sexual Function Index questionnaire. Male survivors had increased levels of erectile dysfunction (18.89% vs. 6.67%; p=.0239) but indicated no difference in sexual desire. Female survivors had a higher prevalence of sexual dysfunction compared with female controls (46.88% vs. 15.22%; p<.0001) and an increased prevalence of moderate-to-severe loss of sexual desire (38.04% vs. 23.26%; p=.0361). Female survivors with sexual dysfunction indicated increased levels of anxiety (p=.0184), depression (p=.0153), and worse physical and mental health (p=.0141 and p=.0419, respectively). Male survivors with erectile dysfunction had higher rates of anxiety and impaired physical health (p=.0147 and p=.0266, respectively). Sexual dysfunction was prevalent in this childhood and adolescent Hodgkin lymphoma survivor cohort and was associated with effects on quality of life. Health care providers must recognize the need for screening and intervention in this group to hopefully contribute to improved overall quality of life.

Trends in Twin Births and Survival in Rural Spain: Evidence from 18th to 20th Century.

This study examines the changes over time of the twinning rate and infant and child mortality across 17 rural villages in the province of Zaragoza (Spain) over a span of 200 years. The aim is to understand how the twinning rate evolved in conjunction with the processes of economic and social modernization, as well as the demographic transition. During the period analyzed, the twinning rate increased by 10%, rising from 1.26 per 1000 births in the second half of the 18th century to 1.38 per 1000 births in the first half of the 20th century. This rate varied due to hereditary issues, biological factors such as the mother's age and parity, and socioeconomic features like family occupation and the mother's education level. In terms of child mortality, twins historically faced a significantly higher mortality rate. However, they benefited greatly from the mortality transition, at least in absolute numbers. While nearly 60% of twins did not survive beyond 5 years of age in earlier periods, the mortality rate for twins decreased to 40% by the first half of the 20th century. The excess mortality was particularly severe for girls, driven by a widespread preference for sons, which led to higher mortality rates for girls in the first 5 years of life, especially in the earliest months. These findings help us understand the improvements in uterine and childhood survival rates for contemporary twins, which can be attributed to the socioeconomic and medical advancements of the 20th century.

Intimate partner violence and childhood health outcomes in 37 sub-Saharan African countries: an analysis of demographic health survey data from 2011 to 2022

Understanding the contribution of intimate partner violence (IPV) to childhood health outcomes (eg, morbidity and mortality) is crucial for improving child survival in sub-Saharan Africa. This comprehensive study aimed to explore the associations between maternal exposure to physical, sexual, or emotional violence and adverse childhood health outcomes in sub-Saharan Africa. We analysed Demographic Health Survey datasets from 37 sub-Saharan African countries from 2011 to 2022. A generalised linear mixed model was used to examine the associations between maternal physical violence, sexual violence, or emotional violence, and early childhood health outcomes (eg, acute respiratory infection, diarrhoea, undernutrition, and child mortality). A random effects meta-analysis was used to calculate pooled odds ratios (ORs) for adverse childhood health outcomes. The odds of undernutrition and mortality were 55% and 58% higher among children younger than 5 years born to mothers who were exposed to physical and sexual violence, respectively. 238 060 children younger than 5 years were included. Children whose mothers experienced physical violence (adjusted OR 1·33, 95% CI 1·29-1·42), sexual violence (1·47, 1·34-1·62), emotional violence (1·39, 1·32-1·47), or a combination of emotional and sexual violence (1·64, 1·20-2·22), or a combination of all the three forms of violence (1·88, 1·62-2·18) were associated with an increased odds of developing diarrhoeal disease. Similarly, children whose mothers experienced physical violence (1·43, 1·28-1·59), sexual violence (1·47, 1·34-1·62), emotional violence (1·39, 1·32-1·47), or a combination of emotional and sexual violence (1·48, 1·16-1·89), or a combination of all three forms of violence (1·66, 1·47-1·88) were positively associated with symptoms of acute respiratory infection. We found a strong link between maternal exposure to IPV and health outcomes for children younger than 5 years in sub-Saharan Africa, with minor variations across countries. To address childhood morbidity and mortality attributed to IPV, interventions need to be tailored for specific countries. Burkina Faso, Burundi, Chad, Comoros, Gabon, Liberia, Nigeria, Sierra Leone, South Africa, and Uganda should be priority nations. None.

The Triglycerides - Glucose Index: An independent predictor of late subclinical cardiotoxicity in adult survivors of childhood, adolescent and young adult cancer

Abstract Introduction The Triglycerides - Glucose index (TyG index) has been identified as a reliable alternative for estimating insulin resistance (IR). Numerous recent studies have provided strong statistical evidence suggesting that this index is associated with the development and prognosis of cardiovascular pathologies. Objectives The aim of this study was to investigate the predictive role of the TyG index on the decrease in left ventricular longitudinal global strain (GLS) assessed on two-dimensional echocardiography in asymptomatic adult survivors of childhood, adolescent and young adult cancer. Methods The study included patients aged 18 years and older, asymptomatic cardiovascular survivors of childhood, adolescent and young adult cancer treated with anthracyclines with or without mediastinal radiotherapy. Anthropometric characteristics, cardiovascular risk factors and cancer treatment-related characteristics were collected. The TyG index was calculated using the formula: ln [fasting triglycerides (mg/dl) × fasting glucose (mg/dl)/2]. GLS was assessed and expressed as an absolute value. A GLS equal to 17.3% was retained as the threshold value after calculation in a referent group matched to patients according to age and gender. Cardiac biomarkers GDF 15, ultra-sensitive troponin I and NT-proBNP levels were measured in addition to fasting blood glucose and lipid profiles. Multivariate analysis using linear regression was performed to identify associations between these different parameters. Results A total of 105 cancer survivors from childhood, adolescence and young adulthood were included. The sex ratio was 1.3. The mean age of the patients was 25 years, the mean time since completion of cancer treatment was 10.6 years, the mean cumulative doses of anthracyclines and mediastinal radiotherapy were successively 245.75 ± 75.14 mg/m2 and 34.6 ± 6.19 Gy. Mean GLS was 18.5 ± 2.83%, mean LVEF 60.6 ± 5.69%. None of the patients had any known diabetes or treatment to lower blood glucose or triglyceride levels. No patient had a history of cardiovascular disease. In the univariate study, the factors associated with lower GLS were patient age at recruitment (p = 0.03), mean time since completion of cancer treatment when this was greater than ten years (p = 0.005), dyslipidemia (p = 0.012), obesity (p = 0.037) and TyG (p = 0.037). In multivariate analysis, lower GLS was related to mean time since completion of cancer treatment (p = 0.015) and TyG index (p = 0.002). Conclusion Our results suggest that the TyG index, as a simple and inexpensive marker of insulin resistance, could help identify cancer survivors from childhood, adolescence and young adulthood who would be at risk of subclinical cardiac dysfunction. Prospective studies with larger numbers are needed to confirm these findings.

Breastfeeding knowledge, attitudes and practices of HIV-positive women in Africa, a systematic review

Abstract Background Breastfeeding (BF) is essential to ensure the health and survival of children, especially in regions where diarrhoea, pneumonia and malnutrition are common causes of child mortality. The WHO currently recommends, along with antiretroviral treatment, exclusive BF (EBF) for the first six months and mixed BF for the next six months and extending it to 24 months. In sub-Saharan Africa, more than one million HIV-positive women face the challenge of infant feeding due to limited access to treatment and safe water. The aim of this study was to understand the knowledge, attitudes, and practices of HIV-positive mothers in Africa to provide evidence for public health strategies. Methods We conducted a systematic review of studies on Knowledge, Attitudes and Practices of BF among HIV-exposed children in African countries, following the principles of the PRISMA statement and identified by searching major databases of records published between 2013 and 2023. Results Of the 498 articles identified, 21 met the inclusion criteria. 70% of the studies were conducted in Ethiopia, South Africa, and Kenya. 95% of the studies were conducted in health care facilities. Mothers showed good knowledge, attitudes and practices regarding EBF of HIV-exposed children, but low knowledge and fear of continuing to practice BF later on. The HIV-positive mothers mentions a range of recommendations received from health workers, identified as their main source of information. Stigma against mothers who practice EBF was found. The primary reason for early cessation of BF was due to work. Conclusions Knowledge, attitudes, and practices of the infant feeding currently recommended by WHO for HIV-positive mothers was weak. There is little evidence of what happens in other African countries and in women with limited access to the health system. Public health policies need to be strengthened to ensure that health workers are trained in the current guidelines to improve HIV-positive women’s BF. Key messages • HIV-positive mothers are afraid to continue breastfeeding their babies after 6 months. • More studies about the breastfeeding practices of children of HIV-positive mothers with limited access to health services are needed.

Outcomes and complications of transvenous implantable cardioverter defibrillator systems in the pediatric population: a systematic review and meta-analysis

Abstract Background Implantable cardioverter defibrillators (ICDs) are an important therapy for prevention of sudden cardiac death (SCD). Data on transvenous (TV) ICD therapy rates, complications, and system survival in children ≤ 21 years is limited by absolute numbers and inclusion of adults with congenital heart disease. Purpose To determine ICD therapy rates and complications in pediatric patients ≤ 21 years of age. Methods A systematic review and meta-analysis were conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Medline, Embase, PubMed Ahead-of-Print and in-process records, and Cochrane Database of Systematic Reviews were searched for full-text articles on pediatric ICD. Articles were assessed for inclusion by two authors via a consensus process; the exclusion criteria included: case reports, review articles, abstracts, editorials, articles not in English, articles solely on epicardial or subcutaneous leads, articles on unrelated topics, articles with &amp;lt;50% ICD leads, and articles with any patients &amp;gt;21 years old. Data were extracted by 1 author and verified by a 2nd author. Meta-analysis of aggregate data was performed, where possible. Random effects models were used for pooled inferences. All reported rates are annualized rates based on reported follow-up times in each study. Results Of 1325 articles, 23 met all inclusion and no exclusion criteria (Figure) representing 1700 patients implanted from 1987-2020. The average age of patients was 12.8 years (95% confidence interval [CI]: 11.9 – 13.7) with weight of 51.1 kg (95% CI: 42.2 – 60.0) (Table). Primary prevention was the indication in 56.4 % (95% CI: 45.0% – 67.7%). Only 14.8% (95% CI: 10.6% – 19.0%) of the patients had congenital heart disease while 22.6% (95% CI: 15.8% – 29.3%) had long QT syndrome. The annualized rate of appropriate shock was 7.0% (95% CI: 5.6% – 8.8%) and the rate of inappropriate shock was 4.8% (95% CI: 3.8% – 6.0%). Annualized rates of reported adverse events included lead failure: 2.3% (95% CI: 1.6% – 3.3%) and infection: 0.8% (95% CI: 0.4% – 1.6%), which could have led to system revision: 4.4% (95% CI: 2.1% – 9.4%). The all-cause mortality rate was 0.8% (95% CI: 0.6% – 1.2%) across 17 studies. In 9 studies with 719 patients, the heart transplant rate was 1.6% (95% CI: 0.6% – 3.9%). Conclusion In this first systematic review and meta-analysis of ICDs in pediatric patients, ICD therapy was effective for prevention of SCD with a 7.0% annualized rate of appropriate ICD shocks. This is comparable to the annualized rate of appropriate ICD shock for secondary prevention of SCD in adult randomized controlled trials. Most common adverse events in the pediatric population were lead failure and system revision. Further refinements in patient selection criteria for implantation and improvements in lead and device technology are needed for pediatric patients.FigureTable

Not only cold but also heat: the effect of maternal exposure to high temperatures during gestation on neonatal mortality in pre-transitional Casalguidi, 1819–1859

Consideration of weather and the environment is becoming increasingly prominent in the field of historical demography. Early studies on infant mortality have paved the way for this type of analysis, shedding light on the significant impact of cold weather conditions on child survival. However, recent research on contemporary populations has drawn attention to the increased risk of adverse birth outcomes due to maternal exposure to heat during pregnancy. The present study aims to validate this finding in a pre-transitional population, specifically focusing on its effects on neonatal mortality. To our knowledge, this analysis is being applied to such populations for the first time, with the goal of exploring whether factors other than cold winters may have also influenced mortality mechanisms during this crucial life stage in historical populations. The results show that heat exposure significantly affected early neonatal mortality, and they also reveal that the susceptibility window was limited to the second trimester of gestation. Temperature-related risks of death were influenced by the tie the family had to the land, with sharecroppers being at the lowest risk. This finding was attributed more to cultural elements associated with the value of children within this social group than to purely economic factors related to living conditions.

Prevalence of Bottle‐Feeding Practice and Associated Factors Among Mothers of Children Under Five in the World, 2024: Systematic Review and Meta‐Analysis

ABSTRACTBackgroundChild‐feeding practices, particularly breastfeeding, significantly impact children's health and survival. However, bottle feeding, although historically practiced, presents numerous disadvantages affecting optimal child nutrition and health. Despite World Health Organisation and The United Nations Children's Fund recommendations against bottle feeding, it remains prevalent globally, affecting roughly 59% of infants worldwide and 85% in Australia by 5 months of age.ObjectiveThis study aims to assess the prevalence and determinants of bottle feeding among mothers of children under five globally.MethodsThis systematic review and meta‐analysis adhered to the Preferred Reporting Items for Systematic Review and Meta‐Analysis guidelines. We comprehensively searched electronic databases for English‐language articles published between 2014 and 2024. The quality of studies was assessed using the Joanna Briggs Institute critical appraisal checklist. Data were analysed in STATA version 17, including summary tables, narrative descriptions, forest plots, and statistical heterogeneity and publication bias assessment.ResultsThe pooled prevalence of bottle feeding among mothers was 57%. Subgroup analysis revealed higher prevalence in larger sample sizes (&gt; 2151) and lower prevalence in smaller ones. Factors significantly associated with bottle feeding included mode of delivery (OR = 1.953; 95%, CI: 1.272, 2.635), child hospitalisation (OR = 1.984, CI: 1.593, 2.376), mother's occupation (OR = 1.579; CI: 1.467, 1.690), post‐natal care (OR = 2.965; CI: (1.358, 4.571), age of children (OR = 2.836; CI: 1.895, 3.777), place of residence (OR = 1.423; CI: 0.994, 1.852), and mother's education (OR = 3.366, CI: 1.949, 4.783).ConclusionEfforts to promote optimal child‐feeding practices should address the identified determinants, emphasising the importance of breastfeeding and providing support to mothers, especially those facing challenges such as cesarean delivery, child hospitalisation, and maternal employment.

Prevalence and pattern of child maltreatment at home among secondary school students in Ibadan North Local Government, Oyo State, Nigeria

BackgroundChild maltreatment is an action that endangers a child's health or survival and is often committed by individuals in positions of responsibility, trust, or power. The extent of maltreatment among secondary school students in developing countries, including Nigeria, requires further exploration, and evaluating this burden can inform preventive interventions. ObjectiveThe study aimed to evaluate the prevalence, pattern and factors associated with maltreatment at home among secondary school students in Ibadan North LGA, Oyo State, Nigeria. Participants and settingA cross-sectional study including 422 students in secondary school was conducted in randomly selected secondary schools in Ibadan North LGA, Nigeria using a multistage-sampling procedure to select students. MethodsThe study used a pre-tested, semi-structured, questionnaire administered by the interviewer, incorporating questions on sociodemographic and the child home version of the ISPCAN Child Abuse Screening Tool (ICAST-CH). Data analysis involved descriptive statistics and the Chi-square test, done by setting the significance level at 5 %. ResultsRespondents had a mean age of 13.9 ± 1.8 years, with 52.1 % being female and 69.5 % living with their parents. More than a quarter (26.8 %) of the respondents experienced all forms of maltreatment, with emotional and physical maltreatment rates at 85.3 % and 81.8 %, respectively, and neglect and sexual maltreatment at 47.4 % and 55.9 %. Age, school type, Parental education, and living arrangements were significantly associated with experience of all forms of maltreatment. ConclusionsAll child maltreatment forms were significantly present among the students. Measures like engaging parents/guardians through parenting programs and sensitization efforts are crucial in reducing the occurrence of maltreatment.

Relapse and survival after relapse among children with cancer in Denmark: 2001-2021.

In recent decades, new first and subsequent lines of anticancer treatment and supportive care have improved survival for children with cancer. We investigated recent temporal changes in the incidence of relapse and survival after relapse among children with cancer in Denmark. This register-based study included 2890 children diagnosed before age 15years with haematological cancers and solid tumours (2001-2021) and central nervous system (CNS) tumours (2010-2021). We used the Aalen-Johansen and Kaplan-Meier estimators to assess cumulative incidence of relapse-defined as cancer recurrence or progression-and survival probability after relapse. Comparing the periods 2001-2010 and 2011-2021, the 5-year cumulative incidence of relapse decreased from 14% to 11% among children with haematological cancers (p=.07), and from 21% to 18% among children with solid tumours (p=.26). Concurrently, the 5-year survival after relapse increased among children with haematological cancers (from 44% to 61%, p=.03) and solid tumours (from 38% to 46%, p=.25). Among children with malignant CNS tumours, the 5-year cumulative incidence of relapse and the 5-year survival after relapse remained stable (49% and 51%, p=.82; and 20% and 18%, p=.90) comparing 2010-2015 and 2016-2021. In recent decades in Denmark, improvements were observed in reducing relapse incidence and increasing survival after relapse in children with haematological cancers and solid tumours. However, the persistent survival gap between children who relapse and those who do not across all childhood cancers underlines the need for intensified and highly targeted treatments for children at high risk of relapse.

Knowledge, Attitude and Practice of Parents to Childhood Immunization: A Cross-Sectional Study in Gandaki Province of Nepal

Introduction: Childhood immunization is one of the most cost effective public health interventions to prevent vaccine-preventable diseases and improve child survival. In Nepal, the national immunization program aims to ensure that all children receive the recommended vaccines, yet challenges remain in achieving universal coverage. The Knowledge, Attitude, and Practice (KAP) of parents towards immunization play a critical role in vaccine uptake. This study was designed to assess their understanding, attitudes, and behaviors toward vaccinating their children. Methods: A prospective observational cross-sectional study was conducted from April 22, 2023, to October 2023 GP Koirala National Centre for Respiratory Diseases and Hospital, Tanahun, Gandaki Nepal, involving 227 parents of children under 18 months. The participants were selected through purposive sampling from Pediatric OPD of this hospital. A structured questionnaire was used to collect data about their knowledge, attitude, and practices regarding childhood immunization. The data were analyzed using SPSS version 23 with descriptive statistics, with results expressed as frequencies and percentages and Chi-square tests employed to identify associations between demographic variables and KAP levels. Results: The study revealed that 73.6% of parents had good knowledge about childhood immunization, recognizing the importance of vaccines and being aware of the vaccination schedule. However, only 64.3% of parents demonstrated a favorable attitude toward immunization, reflecting mixed perceptions about the necessity of vaccines and their safety. Additionally, 60.3% of parents exhibited good practices, indicating that while a majority ensured their children received vaccines, there were still gaps in adherence to the full immunization schedule. Demographic factor such as education level significantly influenced KAP scores. Conclusion: The study highlights the need for continuous efforts to enhance parental knowledge, improve attitudes, and reinforce good practices regarding childhood immunization in Nepal. Although the majority of parents showed a reasonable understanding of vaccines, the discrepancies in attitudes and practices suggest that targeted interventions, including education and outreach, are necessary to improve vaccination rates. Addressing these gaps is crucial to ensuring complete immunization coverage and safeguarding children from preventable diseases. Keywords: Childhood immunization, parental knowledge, vaccination practices, public health, vaccine uptake.

Evaluation of Complementary Feeding Indicators Among Children Aged 6–23 Months According to the Health Literacy Status of Their Mothers

Background/Objectives: Infant and young child feeding (IYCF) practices directly affect child health, development, and survival, especially under 2 years of age and ultimately affect adult life well-being. As the primary caregivers of the children, mothers with higher health literacy may better perceive the benefits of optimal complementary feeding practices, leading to improved health outcomes for their children. In this study, we aimed to assess complementary feeding practices among children aged 6–23 months in Turkey according to 2021 World Health Organization IYCF indicators [minimum dietary diversity (MDD); minimum meal frequency (MMF); minimum acceptable diet (MAD); egg and/or flesh food consumption (EFF); sweet beverage consumption (SwB); unhealthy food consumption (UFC); zero vegetable or fruit consumption (ZVF); and bottle feeding (BoF)] and investigate their associations with sociodemographic characteristics and mothers’ health literacy. Methods: With a descriptive study design, we reached 572 mothers of children aged 6–23 months from five regions of Turkey. We used the Turkey Health Literacy Scale-32 (TSOY-32) to assess mothers’ health literacy. Results: While maternal and child age are significantly associated with more complementary feeding practices, specifically MDD, MAD, and EFF, having multiple children has negative impacts on several complementary feeding indicators, including MDD, MMF, MAD, UFC, and ZVF. The only indicator associated with mothers’ TSOY-32 scores was zero fruit and vegetable consumption. Conclusion: Raising awareness among mothers about the importance of complementary feeding practices and identification of vulnerable groups will guide practitioners and policymakers to improve child health and nutrition.

Current situation of neuropathology in Central America.

The present situation of neuropathology practice in the Central American region has not been addressed in the past. These are low middle-income countries, and therefore, many do not have a basic immunohistochemistry panel. Cytogenetics and molecular studies are not available in most of Central America. Pediatric brain tumors are diagnosed either by anatomical pathologists or by pediatric pathologists. Access to a weakly Latin American Tumor Board is available to consult cases, but most countries do not participate in these expert meetings. The most recent World Health Organization brain tumor book has a very broad molecular classification of pediatric brain tumors. All these factors make it very difficult to properly diagnose pediatric brain tumors in the region, and this impacts the treatment and overall survival of children with brain tumors.

Burden and mortality of congenital gastrointestinal anomalies: insights from a nationwide cohort study.

Improved perioperative care has enhanced survival in children with congenital gastrointestinal conditions and abdominal wall defects (AWD). However, epidemiological and surgical outcomes in developing nations are still scarce. Our aim was to assess the burden and mortality of common congenital gastrointestinal anomalies and AWD in Malaysia, and their influencing factors. Using the Global PaedSurg study protocol with permission, we performed a prospective cohort study on children presenting for the first time between October 2021 and April 2022 with these conditions: Esophageal atresia (EA), congenital diaphragmatic hernia (CDH), intestinal atresia, gastroschisis, exomphalos, anorectal malformation (ARM) and Hirschsprung's disease. We compared mortality and 30-day outcome data across different geographical regions in Malaysia. There were 228 patients with 242 study conditions (EA n = 28, CDH n = 36, intestinal atresia n = 49, gastroschisis n = 12, exomphalos n = 8, ARM n = 77, Hirschsprung's disease n = 32). Our mortality rate was 8.8%; 60% of these were CDH patients. Factors significantly associated with mortality were CDH diagnosis, central venous access requirement, higher American Society of Anesthesiologists (ASA) score, blood transfusion and ventilation requirement. Diagnosis of CDH is the most important predictor for sepsis on arrival and mortality, therefore measures should be taken for early recognition and aggressive management.

Management of Busulfan-Induced Lung Injury in Pediatric Patients with High-Risk Neuroblastoma

Background/Objectives: Integrating the cytotoxic drug busulfan into a high-dose chemotherapy regimen prior to autologous hematopoietic stem cell rescue in patients with high-risk neuroblastoma has improved the survival of children battling this deadly disease. Busulfan-induced toxicities can, however, be severe. Here, we describe the diagnosis and successful treatment of acute pulmonary injury by total-body-weight-adjusted busulfan therapy in two children with high-risk neuroblastoma. Case series: Patient 1 developed life-threatening biphasic acute respiratory failure on days +60 and +100 after busulfan therapy, requiring intubation and invasive mechanical ventilation. Despite intensive anti-inflammatory and immunomodulatory therapy, including systemic corticosteroids, topical inhalation regimens, azithromycin, nintedanib and extracorporal photopheresis, patient 1 required extended intensive care measures and non-invasive respiratory support for a total of 20 months. High-resolution computed tomography showed diffuse intra-alveolar and interstitial patterns. Patient 2 developed partial respiratory failure with insufficient oxygen saturation and dyspnea on day +52 after busulfan therapy. Symptoms were resolved after 6 months of systemic corticosteroids, topical inhalation regimens and azithromycin. High-resolution computed tomography showed atypical pneumonic changes with ground-glass opacities. While both patients fully recovered without evidence of pulmonary fibrosis, cancer therapy had to be paused and then modified until full recovery from busulfan-induced lung injury. Conclusions: Busulfan-induced lung injury requires prompt diagnosis and intervention. Symptoms and signs are nonspecific and difficult to differentiate from other causes. Therapeutic busulfan drug level monitoring and the identification of patients at risk for drug overdosing through promoter polymorphisms in the glutathione S-transferase alpha 1 gene encoding the main enzyme in busulfan metabolism are expected to reduce the risk of busulfan-induced toxicities.

Introduction: Survival of children with high-risk neuroblastoma (HR-NBL) has increased with multimodal therapy. Cis-retinoic acid (cis-RA), cornerstone of HR-NBL therapy, can cause osteoporosis and premature physeal closure, posing a threat to skeletal structure. HR-NBL survivors demonstrate profound growth failure. DXA measures areal bone mineral density (aBMD). DXA is confounded by short stature and fails to distinguish between trabecular and cortical bone. We previously reported no significant difference in height-per-age adjusted aBMD-Z in HR-NBL survivors compared to healthy controls[1]. However, aBMD-Z in severe short stature may attenuate bone density deficits. High-resolution peripheral quantitative computed tomography (HRpQCT) yields 3D measures of volumetric BMD and bone architecture. Objectives: Assess volumetric BMD (vBMD) and cortical structure using distal tibia HRpQCT and leg lean mass by DXA in HR-NBL survivors compared to healthy controls in a cross-sectional study. Methods: We prospectively enrolled 20 HR-NBL survivors (median age 12.2 yrs, range 9.5 to 15.8, 7 female) treated with cis-RA (median age 2.6 yrs at start of therapy, range 0.3-9.1), and 20 age-, sex-, and race-matched healthy controls. We assessed leg lean mass adjusted for leg length by DXA. For HRpQCT, we compared tibia length (cm), cortical and trabecular vBMD (mg HA/cm3), geometry parameters (cortical and trabecular area [mm2]), and structural parameters (cortical thickness [μm] and porosity, trabecular number [mm-[1]] and separation [μm]). Outcomes were compared using Student’s t-test or Mann-Whitney U test. Linear regression models assessed difference in outcomes of bone microarchitecture and leg lean mass between both groups. Results: Compared to controls, tibia length was significantly shorter in HR-NBL survivors (32.3 ± 0.8 vs. 35.7 ± 0.6, P&amp;lt;0.005). HR-NBL survivors demonstrated lower cortical area (187.6 ± 43.8 vs. 218.7 ± 42.3, P&amp;lt;0.05), cortical perimeter (62.4 ± 7.71 vs. 69.5 ± 8.1, P&amp;lt;0.01), and leg lean mass Z-score (-1.47 ± 1.34 vs. -0.20 ± 0.84, P&amp;lt;0.001) compared to controls. Cortical geometry deficits were explained by muscle deficits (P&amp;lt;0.001). Trabecular area, BMC, areal and volumetric BMD, and measures of bone structure were not significantly different in HR-NBL survivors compared to controls. IGF-1 and 25-OH D levels had no significant effects on DXA or HRpQCT parameters. Conclusion: Bone density is not severely impacted in HR-NBL survivors. Muscle deficits persist years after treatment and explain cortical geometry deficits. HRpQCT substantiates prior DXA evaluation in HR-NBL survivors with significant short stature, demonstrating preserved bone density and structure. 1.Guo et al.
