Background: Fluid resuscitation is a cornerstone of septic shock management in pediatric patients, with normal saline (NS) being the traditional choice. However, balanced solutions (BS) have gained attention due to their potential to mitigate acid-base and electrolyte disturbances. Despite this, the optimal choice between BS and NS for pediatric sepsis remains unclear. Therefore, we aimed to conduct a meta-analysis comparing the clinical outcomes of BS versus NS in pediatric patients with sepsis.

Methods: We systematically searched PubMed, EMBASE, and Cochrane Central Register of Controlled Trials, along with reference lists of retrieved publications, for studies comparing clinical outcomes in pediatric patients with sepsis treated with BS versus NS. Our outcomes of interest included acute kidney injury (AKI), hospital mortality, hospital length of stay, pediatric intensive care unit (PICU) length of stay, need for renal replacement therapy, hyperchloremia and mechanical ventilation. We performed statistical analysis using Review Manager Web 8.0.0 and Rstudio.

Results: We included 12,231 patients from 8 studies, of which 4 were randomized clinical trials (RCTs). BS was used to treat septic shock in 2,460 (20.1%) patients. The mean age was 5.98 ± 3.08 years, with 43.82% female patients. Follow-up ranged from 3 to 90 days. We found no statistically significant difference between groups in AKI, hospital mortality, mechanical ventilation, need for renal replacement therapy, and PICU length of stay. Hospital length of stay in days was significantly longer with BS compared to NS (MD 3.38; 95% CI 1.13 to 5.64; p = 0.003; I² = 0%) and the occurrence of hyperchloremia was lower in the BS compared to NS (RR 0.70; 95% CI 0.59 to 0.82; p = 0.0001; I² = 0%). In a subgroup analysis of RCTs only, AKI occurrence was not significantly different between BS and NS groups (RR 0.81; 95% CI 0.48 to 1.38; p = 0.44; I² = 18%). However, the need for renal replacement therapy was significantly less frequent in patients treated with BS compared to NS (RR 0.58; 95% CI 0.39 to 0.87; p = 0.008; I² = 0%).

Conclusion: In pediatric septic shock patients, treatment with balanced solutions (BS) was associated with a lower need for renal replacement therapy and a reduced occurrence of hyperchloremia. However, hospital length of stay was longer in patients treated with BS compared to those receiving normal saline (NS). These results underscore the complexity of fluid management in pediatric septic shock and emphasize the need for further research.

Objective: This study investigates the antimicrobial resistance and clinical features of Staphylococcus aureus (S. aureus) in bone and joint infections (BJIs) among children under 14 years old, providing insights for optimal antibiotic usage.

Methods: A retrospective analysis was conducted on the clinical data from children treated for BJIs at the Children's Hospital of Soochow University between January 2019 to December 2023. Bacterial cultures were examined, focusing on S. aureus. Clinical features of children with methicillin-sensitive Staphylococcus aureus (MSSA) and methicillin-resistant Staphylococcus aureus (MRSA) infections were compared.

Results: Among the 110 cases of culture-positive BJIs, 116 pathogenic strains were identified, with, S. aureus being the most prevalent (75.00%, 87/116). No resistance to quinupristin/dalfopristin, linezolid, vancomycin, tigecycline, rifampin or teicoplanin was detected. The resistance rate to penicillin was 90.80% (79/87), while resistance rates to clindamycin and erythromycin were 37.93% (33/87) and 36.78% (32/87), respectively. MRSA accounted for 28.74% (25/87) of S. aureus isolates. There were no significant differences in gender, age, infection site, clinical symptoms, laboratory indicators, hospital stay, or surgical intervention between MSSA and MRSA groups (p > 0.05). However, patients with positive X-ray findings were more likely to have MRSA infections (p = 0.033). Subgroup analysis revealed that children older than 48 months with positive X-ray results were more likely to have MRSA (p = 0.048).

Conclusion: In China, S. aureus remains the predominant pathogen in children under 14 years old with BJIs. Among children older than 48 months, nearly one-third of BJIs are caused by MRSA, and positive X-ray findings may indicate a higher likelihood of MRSA in this age group. Further studies are required to validate these findings before they can be widely applied.

Background: The onset age of pubertal changes varies widely among girls and has undergone changes over time around the world. This study aimed to determine the age of onset of puberty in healthy Iranian girls living in Isfahan province.

Methods: This cross- sectional study was conducted among 13,886 students aged 6-18 years. They were selected by multistage random cluster sampling from urban and rural areas of Isfahan province of Iran. Pubertal stage was determined according the 5-level Tanner stages proposed by Marshall and Tanner. Trained physicians determined the breast development through both visual inspection and palpation, in addition, mothers assessed their daughter's pubic hair growth using Tanner's Sexual Maturation Scale (SMS) by comparison to standard pictures. The data were analyzed by the status quo method. Probit regression analysis was used to evaluate the median age of onset for each characteristic including menarche, breast and pubic hair.

Results: A total of 13,886 healthy girls with mean age (SD) of 11.97 (2.9) were studied. Overall 6968 (50.2%) girls experienced menstruation with a median (95%CI) age of 12.05(11.88-12.21) years at its onset. The median age for onset of breast development was 9.89 (95% CI: 9.77 - 10.02) years and for onset of pubic hair development was 10.14 (95% CI: 9.88- 10.39) years. The 3rd percentile for breast stage 2 (B2) and pubic hair stage 2 (PH2) was 6.85 and 6.75 years, respectively, and the 97th percentile for B2 and PH2 was 12.94and 13.54 years, respectively.

Conclusion: According to our findings, the onset of puberty before 6.85 years should be considered as precocious puberty for Iranian girls. Our study indicated the secular trend toward earlier menarche in girls. Nationally representative surveys and longitudinal studies are necessary to determine the exact age of puberty for future international comparisons.

Background: Colic in infants is defined as excessive crying in an otherwise healthy and thriving baby. Colic is a common but poorly understood and often frustrating problem for caregivers.

Objective: To study whether osteopathic treatments of infants with infantile colic / excessive crying (IC/EC) have an impact on the subjectively perceived psychological stress of caregivers compared to usual care.

Methods: The study was designed as a prospective, multicenter, randomized controlled trial. Infants aged 1 week to 3 months and who met Rome IV criteria for IC/EC were included. By means of external randomization, infants were allocated to an intervention group or a control group. Infants in the intervention group received three osteopathic treatments at intervals of one weeks. The treatments were custom-tailored and based on osteopathic principles. Controls received their osteopathic treatment after a 3 week untreated period. The primary outcome parameter was the assessment of parental psychological stress (three questions), measured using a numeric rating scale (NRS; 0-10). Furthermore, the average daily crying time (measured using the Likert scale), the crying intensity (measured using the NRS) and the parents' self-confidence (measured using the Karitane Parenting Confidence Scale) were assessed.

Results: A total of 103 infants (average age 39.4 ±19.2 days) were included, 52 in the intervention group and 51 in the control group. An inter-group comparison of changes revealed clinically relevant improvements in favor of the intervention group for the main outcome - parameter psychological stress - for all 3 questions (e.g., for question 2 respectively 3, NRS: between group difference of means 3.5; 95% CI: 2.6 to 4.4; p < 0.001). For the secondary outcome parameters of crying intensity and crying time/day, the changes were of similar magnitude.

Conclusion: Three osteopathic treatments given over a period of two weeks led to statistically significant and clinically relevant positive changes of parental psychological stress.

Background: Children with non-syndromic cleft lip with or without palate (CL ± P) may present alterations in dental development. The purpose of this cross-sectional study was to compare the dental age (DA) between children with and without CL ± P, and whether single nucleotide polymorphisms (SNPs) in genes encoding growth factors are associated with DA variations.

Methods: Children aged between 5 and 14 years with and without CL ± P were recruited to participate in this study. DA was evaluated by calibrated examiners (kappa > 0.80) using the method proposed by Demirjian et al. (1973). Genomic DNA was extracted from buccal cells, and SNPs in Epidermal Growth Factor (EGF) - rs4444903 and rs2237051, Epidermal Growth Factor Receptor (EGFR) - rs2227983 -, Transforming Growth Factor Beta 1 (TGFB1) - rs1800470 and rs4803455 -, and Transforming Growth Factor Beta Receptor 2 (TGFBR2) - rs3087465 - were genotyped by real-time polymerase chain reactions using the TaqMan assay. The Student T-test was used to compare the variations in DA between the phenotypes "with CL ± P" and "without CL ± P", and the ANOVA two-way test was performed to compare the variations in DA among the genotypes (α = 0.05). A post-hoc analysis was performed using Bonferroni correction.

Results: Two hundred and nine (n = 209) children (100 with CL ± P and 109 without CL ± P) with a mean chronological age of 8.66 years - standard deviation (SD) = 1.92 - were included. The group with CL ± P demonstrated a significantly delayed DA (mean=-0.23; SD = 0.71) compared to the group without CL ± P (mean=-0.01; SD = 0.88) (p = 0.049). Genotype distributions were in Hardy-Weinberg equilibrium. The SNP rs4803455 in TGFB1 was significantly associated with DA variations in children without CL ± P (p < 0.01). In the group with CL ± P, no significant differences in DA were observed among the genotypes.

Conclusion: Children with CL ± P presented delayed DA compared with children without CL ± P. The SNP rs4803455 in TGFB1 is associated with variations in DA in children without CL ± P.

Background: Understanding the priorities of parents of children and adolescents with autism spectrum disorder (ASD) is crucial for implementing evidence-based programs. This study aims to identify the functional priorities of parents of Brazilian children and adolescents with ASD, analyze variations in priorities according to the levels of support and age groups of the participants, and categorize the goals according to the categories of the International Classification of Functioning, Disability, and Health (ICF). Additionally, this study aimed to evaluate changes in parents' performance and satisfaction with functional priorities after intervention with the Global Integration Method (Métodode Integração Global - MIG).

Methods: A total of 241 children/adolescents with ASD (mean age, 6.92 ± 3.61 years) were recruited from different regions of Brazil. 76% (76%) were male, and 40.7% were classified as having support level 2. The Canadian Occupational Performance Measure was administered to parents/caregivers to identify their priorities for their children and to assess changes in performance and satisfaction with priorities after intervention with MIG. The MIG protocol consisted of functional task training in a naturalistic environment (City of Tomorrow) combined with the use of a flexible therapeutic suit (MIG Flex) and was conducted for 3 months, five times a week, for 3-4 h per day. Descriptive statistics were used to provide the priority profile. Pre- and post-intervention data were analyzed using paired t-test.

Results: Parents established 1,203 functional priorities. Activities of daily living, behavioral difficulties, communication, play, and social interactions were the main functional priorities in the perception of parents/caregivers. The profiles of functional priorities were similar between the different levels of support and age groups. Approximately 64% of the priorities were classified in the activity domain of the ICF. In general, the MIG program resulted in significant improvements in performance and satisfaction for the majority of functional priorities (p < 0.05).

Conclusion: Activities of daily living appear to be the main priority of parents of children and adolescents with ASD, regardless of the level of support or age group. The MIG program has been associated with improvements in performance and satisfaction across several of the functional priorities identified by parents.

Background: Infections may play a role in the etiology of sudden infant death syndrome (SIDS), with Bordetella pertussis being a potential agent. The objective was to analyze the association of SIDS and infant pertussis hospitalization rates over time, comparing a previously unvaccinated population (West Germany) versus a predominantly vaccinated population (East Germany).

Methods: We calculated SIDS rates per 1000 live births per state. Live births and SIDS were available from 1980 onwards for the West German states and from 1991 onwards for the East German states. We applied interrupted time series (ITS) analyses to investigate the role of two public health interventions in 1991 (West Germany) and in 2000 (West and East Germany), respectively. Infant pertussis hospitalizations were available for five West German and three East German states between 1994 and 2019. We used multilayer and multivariate correlation analyses to determine the correlation between SIDS and pertussis hospitalization rates, including Pearson correlation test and vector autoregressive (VAR) analysis.

Results: In West Germany, the average annual SIDS rate (per 1000 live births) increased from 1.08 in 1980 to 1.68 in 1991, before declining to 1.18 in 1992 and subsequently to 0.10 in 2020. In East Germany, the average annual SIDS rate (per 1000 live births) decreased from 0.79 in 1991 to 0.12 in 2020. The results of the ITS model indicated a significant change in both level and slope at the 1991 interventions (West Germany) and in slope at the 2000 interventions (West and East Germany). The correlation coefficients between SIDS and infant pertussis hospitalization rates were 0.69 (95% CI [confidence interval] 0.41, 0.85; p < 0.001) in West Germany, and 0.41 (95% CI 0.03, 0.69; p = 0.037) in East Germany. The correlation decreased during later periods (2000-2019, 2010-2019), particularly in East Germany. The results of the VAR analysis corroborated the findings of the main analyses.

Conclusions: SIDS and infant pertussis hospitalization rates were correlated in both West and East Germany. Further studies - including improved diagnostic assessment of pertussis - seem warranted.

Background: Growing evidence shows that dysregulated metabolic intrauterine environments can affect offspring's neurodevelopment and behaviour. However, the results of individual cohort studies have been inconsistent. We aimed to investigate the association between maternal diabetes before pregnancy and gestational diabetes mellitus (GDM) with neurodevelopmental, cognitive and behavioural outcomes in children.

Methods: Harmonised data from > 200 000 mother-child pairs across ten birth cohorts in Europe and Australia were available. Mother-child pairs were included for analysis to determine whether GDM was recorded (yes or no) and whether at least one neurodevelopmental, cognitive and behavioural outcome was available in children aged 3 to 13 years. Confounder-adjusted regression models were used to estimate associations between maternal diabetes and child outcomes using two-stage individual participant data (IPD) meta-analysis. Model 1 included a crude estimate. The full adjustment model (model 2) included adjustment for child sex, maternal age, pre-pregnancy BMI, pregnancy weight gain, maternal smoking during pregnancy, plurality, parity and maternal education.

Results: Children (aged 7-10 years) born to mothers with GDM had higher attention-deficient hyperactive disorder (ADHD) symptoms compared to non-exposed controls (model 2, regression coefficient (β) 3.67 (95% CI 1.13, 6.20), P = 0.001). Moreover, children (aged 4-6 years) born to mothers with GDM exhibited more externalising problems than those born to mothers without GDM (model 2, β 2.77 (95% CI 0.52, 5.02), P = 0.01). A pre-existing maternal history of type 1 and type 2 diabetes mellitus was associated with ADHD symptoms at 4-6 years (model 1, β 8.82 (95% CI 2.21, 15.45, P = 0.009) and β 7.90 (95% CI 0.82, 14.98, P = 0.02), respectively). The association was no longer apparent in further adjustments.

Conclusions: This study found that children between 4 - 6 and 7-10 years of age born to mothers with GDM have a greater likelihood of developing externalising problems and ADHD symptoms, respectively. Externalising problems often co-exist with ADHD symptoms and precede formal ADHD diagnosis. Overall, this large-scale multi-cohort study suggested that a dysregulated metabolic environment during pregnancy may contribute to ADHD symptoms and externalising problems in young children.

Background: Breastfeeding is the cornerstone of a newborn's nutrition, containing crucial nutritional components. While a substantial body of research focuses on mothers, there is limited understanding regarding effective strategies to engage fathers in promoting breastfeeding practices. Therefore, this quasi-experimental study investigated a community-based intervention to improve breastfeeding exclusivity and initiation rates by targeting fathers in breastfeeding education.

Methods: This research was conducted in Dessie City in the Amhara region of Northeast Ethiopia from 5th October 2020 to 30th August 2021. Fathers and their wives were assigned individually to the intervention and control groups. Baseline data were gathered from selected Kebeles (Kebele: the lowest administrative level in Ethiopia) to identify couples seeking care through routine maternal and child health services. Fathers in the intervention area received breastfeeding education services at health facilities or home visits during antenatal, delivery, and postpartum periods. Trained midwives participated in giving breastfeeding education. In the control arm, they received routine counseling activities. Factors associated with early initiation and exclusive breastfeeding were analyzed using multivariable analysis among the two groups.

Results: The intervention involved 327 participants, 155 in the intervention arm and 172 in the control group. The multivariable analysis indicated that the community-based father health education intervention significantly influenced the early initiation of breastfeeding. Mothers in the intervention group were found to be nearly five times more likely to initiate breastfeeding within the first hour of their infants' lives (AOR: 4.85, 95% CI: 1.36-17.32). A significant positive impact was also found for exclusive breastfeeding (EBF) of infants at the 1st, 4th, and 6th months (AOR: 3.95, 95% CI: 1.09-14.27), (AOR: 5.47, 95%CI: 2.18-13.70), and (AOR: 1.70, 95% CI: 1.02-2.85) respectively.

Conclusion: This study confirmed the positive effects of a community-based father education intervention on the rates of exclusive breastfeeding during the first, fourth, and sixth months, as well as the early initiation of breastfeeding. The government and healthcare workers should implement policies supporting father-inclusive breastfeeding initiatives such as creating awareness and the critical role fathers' play.

Background: The diagnosis of depression or anxiety treated by SSRIs has become relatively common in women of childbearing age. However, the impact of gestational SSRI treatment on newborn thyroid function is lacking. We explored the impact of gestational SSRI treatment on newborn thyroid function as measured by the National Newborn Screening (NBS) Program and identified contributory factors.

Methods: An observational large-scale study of mother-infant dyads of liveborn infants delivered between 2011 and 2022. The Israeli NBS Program thyroid dataset [total thyroxine (TT4) obtained between 36-72 h after delivery] was linked with the electronic medical records of mothers and their infants born at Lis Maternity and Women's Hospital, to generate a unified database. The MDClone big data platform was utilized to extract maternal, perinatal, and neonatal characteristics from the medical records of mother-infant dyads. Only term liveborn infants born to mothers without documented thyroid disease and/or chronic medication administration, except for SSRIs, were included in order to minimize potential confounding effects on the infant's thyroid function. Group stratification relied on the documentation of gestational SSRIs treatment. The variables of interest were maternal, pregnancy, delivery, and perinatal characteristics of the mother-infant dyads. Multivariable forward linear regression model was applied to evaluate explanatory variables for newborn total thyroxine (TT4) levels.

Results: Out of 105,928 infant-mother dyads, 2321(2.2%) mothers had been treated with SSRIs during pregnancy. The SSRI-treated mothers were older (34.8 ± 4.7 vs 32.6 ± 4.8 years, p < 0.001) and had a higher pre-pregnancy body mass index (23.4 ± 4.5 vs 22.7 ± 4.1, p < 0.001), but similar mean weight gain (13 kg) during pregnancy. Cesarean delivery was more common among SSRI-treated mothers than in the general population (p < 0.001). Infants of SSRI-treated mothers had lower WHO-classified birthweight z-scores (-0.25 ± 0.93 vs -0.04 ± 0.92, p < 0.001) and a higher rate of small-for-gestational-age infants (13.4% vs 8.2%, p < 0.001). A multivariable forward linear regression model revealed that SSRI treatment during pregnancy was not a significant contributor to TT4 levels (p = 0.497).

Conclusions: SSRI treatment during pregnancy had no direct effect upon the newborn's adaptation of the hypothalamic-pituitary-thyroidal axis, but several other maternal and delivery characteristics were revealed to possibly impact newborn thyroid function.
