Background: In late 2019, a new respiratory illness was detected in Wuhan, China and was later designated as COVID-19 by the WHO. Despite international efforts to impose restrictions and quarantine measures, the virus spreads rapidly across the globe. The pandemic has significantly impacted the mental health of both children and parents. This study investigates the relationship between parents' anxiety, stress and depression, and Children's Health-Related Quality of Life (CHQol) and externalised behavioural disorders during the COVID-19 pandemic.

Methods: This is a cross-sectional study that included 396 parents who have children between the ages of 6 and 18 years old. Sampling was done by designing an online questionnaire that was distributed on social media (WhatsApp and Telegram and native social media, such as Eitaa, Soroush and E-Gap). Inclusion criteria were all citizens living in rural and urban areas of Rafsanjan, citizens living in Rafsanjan city for 1 year and having children aged 6-18 years old. We used a demographic information questionnaire, Depression, Anxiety, Stress Scale-21, CHQol and Achenbach System of Empirically Based Assessment to collect data.

Results: We found a positive significant correlation between anxiety (r=0.334), stress (r=0.354), depression (r=0.324) and externalised behavioural disorder (p<0.001). Depression and anxiety predicted 22% of the variance of the CHQol (p<0.001) while age, stress, use of masks and gloves to prevent infection, and anxiety predicted 19% of the variance of externalised behavioural disorder (p<0.001).

Conclusion: Parents experienced high levels of symptoms of anxiety, stress and depression during the COVID-19 outbreak, which can be associated with behavioural disorders in their children and negatively impact their health. Therefore, it is crucial to pay more attention to the mental state of parents and its complications for children.

In Malawi, tetanus toxoid vaccination (TTV) is recommended in pregnancy, but few studies have assessed the prevalence of infant seroprotection against tetanus. Anti-TT levels from 84 6-week-old infants, born in 2019-2020 to mothers living with HIV (HEU: HIV-exposed-uninfected) infants and to HIV-negative women (HUU: HIV-unexposed-uninfected) infants were determined by ELISA assay. Although 94% of the infants (HEU=94.8%, HUU=92.3%) showed protective levels (>0.1 IU/mL), the mean titers observed (0.51 IU/mL) suggest an incomplete compliance with TT vaccination. The only factor positively correlated to anti-TT IgG levels was the duration of maternal antiretroviral therapy in HEU.

Background: Academic detailing, audit and feedback, and peer comparison have been advocated as effective ways to promote appropriateness of prescribing and antimicrobial stewardship (AMS). This study explored the effectiveness of a multifaceted intervention aimed at supporting the appropriateness of antibiotic prescribing in paediatrics.

Methods: Over the course of 7 years, all 89 paediatricians of the Local Health Authority (LHA) of Reggio Emilia (530 000 residents) were provided with scientific literature focused on antimicrobial resistance and the appropriateness of use of specific antibiotics, together with local data on antimicrobial resistance and prescribing reports comparing each paediatrician with colleagues in the same district and with local averages. Prescribing rates of specific target antibiotics/classes of antibiotics were evaluated by comparing Reggio-Emilia with the other seven LHAs of the Emilia-Romagna Region (control area), adjusting for prescriptions during a 2-year baseline period.

Results: A significant increase in the rate of amoxicillin prescriptions (91 more per 1000 children/year) was observed in the intervention area compared with the control area along with a significant reduction in the rate of amoxicillin+clavulanate prescriptions (70 fewer per 1000 children/year) and a significant increase in the ratio of their prescription rates. No differences were observed in cephalosporin and macrolide prescription rates and overall antibiotic prescriptions.

Conclusions: Improvements in prescribing appropriateness were observed. This study confirms the importance of an audit and feedback approach through small group meetings supported by scientific literature, local resistance data and prescribing reports. Such approach should always be considered as part of multifaceted interventions to promote AMS.

Background: Continuous renal replacement therapy (CRRT) is commonly used for the treatment of acute kidney injury (AKI) in critically ill neonates. This study investigated the effectiveness and feasibility of CRRT for AKI in neonates who weigh ≤3 kg.

Methods: Data from 19 neonates with a weight ≤3 kg and AKI who underwent CRRT at two centres between January 2015 and October 2021 were collected retrospectively. Kidney function, circulatory function, complications and clinical outcomes were recorded. Repeated-measures analyses of variance, t-tests and non-parametric tests were conducted.

Results: The median patient age at CRRT initiation was 3 days (IQR: 1-7 days). The median patient weight at CRRT initiation was 2.67 kg (IQR: 2.20-2.85 kg). The median CCRT duration was 46 hours (IQR: 32-72 hours). The serum creatinine and blood urea nitrogen levels decreased significantly, and the mean arterial pressure increased significantly after 12 hours of CRRT and at the end of CRRT. The urinary output was significantly increased at the end of CRRT. 11 patients had thrombocytopaenia, 6 had electrolyte disorders and 3 had blocked tubes. Five patients were discharged, six died after their parents chose to discontinue treatment and eight died after active treatment. Weight at CRRT initiation and urinary output at the end of CRRT were significantly lower among patients who died than among patients who survived.

Conclusions: CRRT is feasible and effective for AKI in neonates who weigh ≤3 kg when accompanied by elaborate supportive care. Lower body weight and persistent oliguria may be correlated with an increased risk of poor clinical outcomes.

Background: To reduce health inequities in paediatric patients with complex diseases, our hospital developed a food security programme in 2022. The programme aims to mitigate food insecurity (FI) in paediatric patients with oncological, transplantation and congenital cardiovascular diagnoses, by providing a monthly nutritious food supply that covers up to 50% of the patient's family food intake, accompanied by social and nutritional follow-up. In this study, we aimed to assess the effect of the programme on FI and nutritional status and describe its implementation.

Method: We conducted a before-and-after study of patients who entered the programme in a 14-month period. We used the Escala Latinoamericana y Caribeña de Seguridad Alimentaria (ELCSA) scale score, FI level and nutritional status measures to assess the effect of the programme. We used the Wilcoxon and McNemar tests to assess changes in scores and proportions of patients with moderate and severe FI, respectively, 31.5%-14.4% (p=0.0008) and of moderate FI from 68.5% to 36.9%.

Results: 111 patients were included. They had a baseline median (IQR) ELCSA score=8 (7-11) that changed to 6 (4-9) (p<0.0001). Severe FI according to ELCSA changed from 31.5% to 14.4% (p<0.001) and moderate from 68.5% to 36.9% (p<0.001). We found no differences in nutritional status regarding height for age (49.5% vs 51.3%, p=0.76), weight for height (42.5% vs 59.1%, p=0.75) or body mass index for age (38% vs 46%, p=0.42) CONCLUSION: The programme reduced FI in families by improving its level to mild or moderate. Children who entered the programme maintained an appropriate nutritional status despite the considerable risk of malnutrition described for oncological paediatric patients and paediatric solid organ transplantation receptors.

Background: Placental histological chorioamnionitis (HCA) is recognised as a significant risk factor for various adverse neonatal outcomes. This study aims to explore if the inflammatory protein levels in neonates were associated with HCA.

Methods: All women with singleton births from February 2020 to November 2022 were selected and divided into three groups based on maternal placental pathology results: the HCA-stage 1 group (n=24), the HCA-stage 2 group (n=16) and the control group (n=17). Olink Target 96 Inflammation Panel was used to detect the levels of 92 inflammation-related proteins in the plasma of newborns from all three groups within 24 hours after birth. We compared the protein profiles through differential protein expression analysis.

Results: A total of six inflammation-related proteins exhibited significant differences between the HCA-stage 1 and the control group. Specifically, TRANCE and CST5 were significantly upregulated (p=0.006, p=0.025, respectively), whereas the expression of IFN-gamma, CXCL9, CXCL10 and CCL19 was significantly downregulated (p=0.040, p=0.046, p=0.007, p=0.006, respectively). HCA-stage 2 newborns had significantly elevated levels of CD5 and CD6 and decreased IFN-gamma, CXCL10 and CCL19 in comparison to controls. These differential proteins were significantly enriched in positive regulation of cytokine activity, leucocyte chemotaxis and positive regulation of T-cell activation pathway-related Gene Ontology terms. Kyoto Encyclopedia of Genes and Genomes pathway analysis revealed that viral protein interaction with cytokine and cytokine receptor, interleukin-17/NF-kappa B/toll-like receptor/chemokine signalling pathway, and cytokine-cytokine receptor interaction exhibited significant differences. Spearman analysis demonstrated a significant positive connection between the levels of CD6 and CD5 proteins, not only in neonatal leucocytes but also in maternal leucocytes. Additionally, CD6 was found to be associated with neonatal birth weight.

Conclusions: In conclusion, placental histological changes associated with chorioamnionitis appear to influence the expression of inflammatory proteins in offspring. Notably, CD6 and CD5 proteins may potentially contribute to the pathogenesis of HCA-related neonatal diseases.

Background: Despite evidence showing that the intranasal and sublingual routes are safe and effective in providing analgesia, no data are available about their day-to-day use in the emergency department (ED). The aim of this study was to assess the frequency of the use of the intranasal and sublingual routes, and the clinical characteristics of the patients receiving analgesia through these routes.

Methods: A multicentre study was performed in the EDs participating in the Pain in Paediatric Emergency Room research group. It included a survey and a retrospective data collection in which the medical records of all patients who received analgesia from 1 April 2022 to 31 May 2022 were collected.

Results: 48 centres (91%) answered the survey. The intranasal and sublingual routes were used in 25 centres (52%). 13 centres (27%) used both routes, 9 centres (19%) used only the sublingual and 3 centres (6%) used only the intranasal route.12 centres (48%) participated in the retrospective study. Data about 3409 patients, median age 9 years (IQR 5-12), were collected. Among them, 337 patients (9.6%) received sublingual analgesia, and 87 patients (2.5%) received intranasal analgesia. The intranasal route was employed for injuries in 79 (90.8%) cases, and fentanyl was the drug delivered in 85 (97.7%) cases. The sublingual route was used mainly for injuries (57.3%), but also for abdominal pain (15.4%), musculoskeletal pain (14.5%) and headache (10.7%). Paracetamol, ketorolac and tramadol were administered through this route.

Conclusions: The use of the intranasal and sublingual routes for analgesia in the paediatric ED is still limited.

Objective: Estimating children's target height (TH) plays an important role in diagnosing, evaluating and treating many paediatric endocrinological diseases. However, in many countries, employing Tanner's formula to predict children's final adult height (FAH) is considered misleading. Therefore, this study aimed to re-evaluate the validity of Tanner's formula for predicting the TH of Korean adolescents and young adults and develop a new formula suitable for Korean children.

Design/setting: Data were derived from the Korean National Health and Nutrition Examination Survey 2010-2019.

Patients: A total of 2586 participants (1266 men, 1320 women) were included, excluding participants for whom Tanner's formula could not be calculated because of missing parental height data.

Main outcome measures: Tanner-based TH was compared with the FAH.

Results: The difference between Tanner-based TH and FAH was 4.86±0.178 cm for men and 4.81±0.150 cm for women. Sex-specific univariable and multivariable analyses were conducted to determine variables influencing positive height gap (greater than estimated TH). Both men and women with higher education levels were more likely to exhibit a positive height gap. Those with a history of chronic illness were less likely to exhibit a positive height gap, particularly in women. Using a new formula derived using linear regression analysis, the sum of parental heights explained 27.6% and 30.6% of the variance in sons' and daughters' heights, respectively.

Conclusions: Tanner's formula for calculating TH tended to underestimate FAH; hence, our new formula may offer a better alternative for estimating TH and evaluating growth in Korean children and adolescents.

Background: There have been concerns about the potential cardiovascular (CV) adverse effects associated with methylphenidate (MTH) use. However, only limited evidence exists on the long-term safety of MTH.

Objective: To evaluate whether MTH use is associated with long-term CV risk.

Methods: This was a retrospective cohort study using 2003-2017 data from the Health and Welfare Database in Taiwan. Patients newly diagnosed with attention deficit and hyperactivity disorder (ADHD) and between 3 and 18 years of age were included. Two treatment statuses were assessed: initial treatment ≥7 days and ≥180 days. Patients treated with MTH were compared with those receiving non-medication therapy. One-to-one propensity score matching was used to balance between-group differences. Study outcomes included major CV events, chronic CV disease, cardiogenic shock and all-cause mortality. Cox proportional hazard models were used to estimate HRs between the two groups.

Results: We began with 307 459 patients with ADHD. After exclusion, 224 732 patients were included in the final cohort. The results showed that compared with non-ADHD medication users, patients who were treated with MTH for more than 7 days had a similar risk of major CV events (HR 0.85, 95% CI 0.72 to 0.99; p=0.040). Identical trends were found in groups who were treated for more than 180 days (HR 0.83, 95% CI 0.69 to 1.00; p=0.050). The results of the sensitivity analyses were consistent with the main analyses across all groups and individual outcomes.

Conclusion: Short-term MTH use did not increase CV risk among patients with ADHD. More evidence on long-term MTH use and risk of cardiogenic shock and death is warranted.
