RESUMO
BACKGROUND: Pediatric patients with eating disorders in a multicenter joint study on 11 facilities were enrolled and prospectively investigated to determine whether improvement in body weight, eating attitudes, and psychosocial factors in children with eating disorders would also improve depressive symptoms. METHODS: In this study, 91 patients were enrolled between April 2014 and March 2016. The severity of underweight was assessed using the body mass index-standard deviation score (BMI-SDS), eating behavior was assessed using the children's eating attitude test (ChEAT26), the outcome of childhood eating disorders was assessed using the childhood eating disorder outcome scale, and depressive symptoms were assessed using the Children's Depression Inventory (CDI) score. RESULTS: After 12 months of treatment, depressive symptoms were evaluated in 62 of the 91 cases where it was evaluated at the initial phase. There was no difference in background characteristics between the included patients and the 29 patients who dropped out. A paired-sample t-test revealed a significant decrease in CDI scores after 12 months of treatment (p < 0.001, 95% CI: 2.401-7.373) and a significant increase in the BMI-SDS (p < 0.001, 95% CI: - 2.41973-1.45321). Multiple regression analysis revealed that BMI-SDS and ChEAT26 scores at the initial phase were beneficial in CDI recovery. In addition, BMI-SDS at the initial phase was useful for predicting BMI-SDS recovery after 12 months of treatment. CONCLUSIONS: Depressive symptoms in children with eating disorders improved with therapeutic intervention on body weight and eating attitudes. TRIAL REGISTRATION: The Clinical Trial Number for this study is UMIN000055004.

BACKGROUND: School closures and social distancing may have affected mental health among preadolescent and adolescent children, who are in a social developmental stage. Rates of anxiety, depression, and stress have been reported to have increased during the COVID-19 pandemic among teenagers worldwide. However, most studies have measured children's mental health in cross-sectional studies or short-term comparisons before and after lockdowns and school closures, and few studies have tracked the long-term effects on mental health among children and adolescents, despite the pandemic lasting more than 2 years. METHODS: An interrupted time-series analysis was performed for longitudinal changes in the monthly number of new mental disorders (eating disorders, schizophrenia, mood disorders, and somatoform disorders). Using a nationwide multicenter electronic health records database in Japan, we analyzed data of patients aged 9 to 18 years from 45 facilities that provided complete data throughout the study period. The study period covered January 2017 to May 2021, defining a national school closure as an intervention event. We modeled the monthly new diagnoses of each mental disorder using a segmented Poisson regression model. RESULTS: The number of new diagnoses throughout the study period was 362 for eating disorders, 1104 for schizophrenia, 926 for mood disorders, and 1836 for somatoform disorders. The slope of the regression line in monthly number of new diagnoses increased in the post-pandemic period for all targeted mental disorders (change in slope for eating disorders 1.05, 95% confidence interval [CI] 1.00-1.11; schizophrenia 1.04, 95% CI 1.01-1.07; mood disorders 1.04, 95% CI 1.01-1.07; and somatoform disorders 1.04 95% CI 1.02-1.07). The number of new diagnoses for schizophrenia and mood disorders increased early after school closure; while eating disorders showed an increasing trend several months later. Somatoform disorders showed a decreasing trend followed by an increasing trend. Time trends by sex and age also differed for each mental disorder. CONCLUSIONS: In the post-pandemic period, the number of new cases increased over time for eating disorders, schizophrenia, mood disorders, and somatoform disorders. The timing of increase and trends by sex and age differed for each mental disorder.

BACKGROUND: Orthostatic intolerance (OI), which is common in children and adolescents, negatively impacts their quality of life (QOL) due to physical symptoms that limit work, school, and daily activities. The purpose of this study is to explore the association of physical and psychosocial factors with QOL scores in children and adolescents with OI. METHODS: A cross sectional observational study was conducted. The study participants included 95 Japanese pediatric patients of age 9-15 years who were diagnosed with OI from April 2010 to March 2020. The QOL scores and the QOL T-scores of children with OI assessed using the KINDL-R questionnaire at the initial visit were compared with conventional normative data. The associations of physical and psychosocial factors with the QOL T-scores were examined using multiple linear regression. RESULTS: Pediatric patients with OI had significantly lower QOL scores than healthy children in both elementary (50.7 ± 13.5 vs. 67.9 ± 13.4, p < 0.001) and junior high schools (51.8 ± 14.6 vs. 61.3 ± 12.6, p < 0.001). This finding was observed in the physical, mental, self-esteem, friends, and school domains. Total QOL scores were significantly associated with school nonattendance (ß = - 3.2, 95% confidence interval [CI] = - 5.8 to - 0.5, p = 0.022) and poor relationship with school (ß = - 5.0, 95% CI = - 9.8 to - 0.4, p = 0.035). CONCLUSIONS: These results suggest that the assessment of QOL, including both physical and psychosocial aspects, especially school factors, needs to be implemented earlier in children and adolescents with OI.
RESUMO
Psychosomatic disorders are influenced by psychosocial factors such as interpersonal relationships. Coping behaviors, especially in frustrating situations, reflect a patient's ability to cope with stress, and it is important to assess these behaviors for the treatment of psychosomatic diseases. This study aimed to clarify the interpersonal relationships and coping behaviors of pediatric patients with psychosomatic diseases during frustrating situations simulated using the Rosenzweig Picture-Frustration study. This retrospective study included 126 patients (41 male, 85 female) with an average age of 12.9 (6-16) years who were consulted at the Department of Pediatric Psychosomatic Medicine at Okayama University Hospital from 2013 to 2018 and underwent the P-F study. Each score was compared with a standardization sample. The mean group conformity rating did not differ significantly between the participants and healthy children. Compared with healthy children, those with psychosomatic diseases were less likely to explain their perspective. The children with psychosomatic disorders responded to frustrating situations in a sensible and age-appropriate manner. However, they were less likely to respond by explaining their perspective to protect themselves.

BACKGROUND: Adolescent health promotion is important in preventing risk behaviors and improving mental health. Health promotion during adolescence has been shown to contribute to the prevention of late onset of the mental health disease. However, scalable interventions have not been established yet. OBJECTIVE: This study was designed to test the efficacy of two adolescent health promotion interventions: a well-care visit (WCV) with a risk assessment interview and counseling and self-monitoring with a smartphone cognitive behavioral therapy (CBT) app. Our hypothesis was that participants who had received both WCV and the CBT app would have better outcomes than those who had received only WCV or those who had not received any intervention. We conducted a prospective multi-institutional randomized controlled trial. METHODS: Participants were 217 adolescents aged 13-18 years. They were randomly divided into two intervention groups (WCV group and WCV with CBT app group) and a nonintervention group. WCV comprised a standardized physical examination along with a structured interview and counseling for youth risk assessment, which was designed with reference to the Guideline for Health Supervision of Adolescents of Bright Futures. A smartphone-based CBT program was developed based on the CBT approach. The CBT app comprised a 1-week psychoeducation component and a 1-week self-monitoring component. During the CBT program, participants created several self-monitoring sheets based on the CBT model with five window panels: event, thoughts, feelings, body response, and actions. The primary outcome was the change in scores for depressive symptoms. Secondary outcomes included changes in scores for self-esteem, quality of life, self-monitoring, and an adolescent health promotion scale. These outcomes were evaluated at baseline and at 1, 2, and 4 months after baseline. The exploratory outcome was the presence of suicidal ideation during the observation period. Intervention effects were estimated using mixed effect models. RESULTS: In total, 94% (204/217) of the participants completed the 4-month evaluation. Both intervention groups showed a significant effect in the form of reduced scores for depressive symptoms at 1 month in high school students; however, these effects were not observed at 2 and 4 months. The intervention effect was significantly more predominant in those scoring above cutoff for depressive symptoms. There was significantly less suicidal ideation in the intervention groups. As for secondary outcomes, there was significant increase in health promotion scale scores at the 4-month follow-up among junior high school students in the WCV group. Moreover, the CBT app was significantly effective in terms of obtaining self-monitoring skills and reducing depressive symptoms. CONCLUSIONS: Although adolescent health promotion interventions may have short-term benefits, the frequency of WCV and further revision of the CBT app should be considered to evaluate long-term effectiveness.

BACKGROUND: Autism spectrum disorder (ASD) and feeding and eating disorders (FEDs) such as anorexia nervosa (AN) are strongly linked as evidenced by frequent comorbidity and overlapping traits. However, eating and social behaviors are shaped by culture, so it is critical to examine these associations in different populations. Moreover, FEDs are heterogeneous, and there has been no examination of autistic traits in avoidant/restrictive food intake disorder (ARFID). METHODS: Therefore, we investigated the prevalence of ASD and autistic traits among Japanese children with AN (n = 92) or ARFID (n = 32) from a prospective multicenter cohort study using the Autism Spectrum Quotient Children's version (AQC) and Children's Eating Attitudes Test (ChEAT26). RESULTS: ASD prevalence was high in both AN and ARFID (16.3 and 12.5%, respectively). The AN group exhibited significantly higher scores on all AQC subscales than an age-matched healthy control (HC) group, but there were no significant correlations between AQC scores and ChEAT26 scores. In the AFRID group, AQC scores did not differ from HCs, but significant correlations were found between total AQC and ChEAT26 scores and between several AQC and ChEAT26 subscales. CONCLUSIONS: Both the AN and ARFID groups had high prevalence rates of ASD. The AN group showed a significantly higher degree of autistic traits than the HC group; however, no difference was found between the ARFID and HC groups. Clinicians need to be aware of these rates when working with children with ED.
RESUMO
We developed and validated a childhood eating disorder outcome scale based on outcomes associated with body mass index standard deviation score (BMI-SDS). This prospective observational study included 131 children with eating disorders (aged 5-15 years). Participants' outcomes scales were completed at the first visit and at 1, 3, 6, and 12 months. The scale evaluated 12 outcomes: body weight change (BW), eating attitude (EA), fear of being fat (FF), body image distortion (BD), menstruation (ME), perceived physical condition (PC), attending school (AS), disease recognition by school (RS), family function (FA), disease recognition by parent (RP), social adaptation (SA), and relationships with friends (RF). Responses to all items were on a four-point Likert scale. Exploratory factor analysis was used to determine the number of factors based on the 12 outcomes. The relation between outcome scale scores and BMI-SDS over the 12-month follow-up period was analyzed. Two types of factors were extracted: disease-specific factors (EA, FF, BD) and biopsychosocial factors (BW, PC, AS, FA, SA, RF). Three items (ME, RS, RP) were excluded because they showed no significant loading effect. There was a significant negative correlation between the outcome scale and BMI-SDS, and changes in outcome scale scores from baseline to 12 months were significantly associated with improvement in BMI-SDS. We developed a childhood eating disorder outcome scale characterized by disease-specific and biopsychosocial factors. Biopsychosocial management combined with a therapeutic approach for disease-specific symptoms may support body weight recovery for children with eating disorders.
RESUMO
Benzodiazepine receptor agonists are widely prescribed therapeutic agents, alter gamma-aminobutyric acid (GABA)A receptor function, and have hypnotic, anxiolytic, anticonvulsant, and antispastic effects. GABAA receptor activity increases under systemic inflammatory conditions. We investigated the effect of benzodiazepine receptor agonists on pentobarbital-induced loss of righting reflex (LORR) duration using a mouse model of lipopolysaccharide (LPS)-induced inflammation. We assessed pentobarbital-induced LORR duration 24â¯h after LPS treatment in mice. Additionally, we examined the microglial response by immunohistochemistry and serum IL-6 and TNF-α concentrations in mice. LPS treatment significantly increased the duration of pentobarbital-induced LORR in mice treated with benzodiazepine receptor agonists (diazepam and brotizolam) and a GABAA receptor agonist (muscimol) compared to that of mice treated with vehicle. These effects were blocked by bicuculline, a GABAA receptor antagonist. LPS significantly increased the number of ionized calcium binding adapter molecule-1-positive hippocampal cells 2 and 24â¯h after treatment. The enhancing effect of diazepam in LPS-treated mice was significantly reduced by minocycline. These findings suggest that LPS enhances pentobarbital-induced LORR duration in mice treated with benzodiazepine via GABAA receptor activity.

BACKGROUND: Pediatric papillary thyroid carcinoma frequently presents with lymph node involvement and distant metastases. Sorafenib, an oral multikinase inhibitor, has been used to treat radioactive iodine (RAI) therapy-refractory thyroid carcinoma in adults; however, pediatric experience is limited. Medical procedures and hospitalization for children with autism spectrum disorder may be challenging. CASE PRESENTATION: An 11-year-old boy with autism spectrum disorder and moderate intellectual impairment presented with dyspnea on exertion with thyroid carcinoma and diffuses lung metastases. Total thyroidectomy and adjuvant RAI therapy is the standard treatment; however, the latter therapy was impractical because of his respiratory status and challenging behaviors. He was therefore started on sorafenib 200 mg/day (150 mg/m2/day) and this dosage was increased to 400 mg/day (300 mg/m2/day). The adverse effects were mild and tolerable. After administration of medication, his dyspnea improved and surgery was performed. We attempted to administer RAI therapy after surgery; however, we abandoned it because he had difficulty taking care of himself according to isolation room rules. Thyrotropin suppression therapy was therefore started and sorafenib treatment (400 mg/day) resumed. Follow-up imaging showed regression of pulmonary metastases. The metastases have remained stable for over 24 months on continuous sorafenib treatment without serious adverse events. CONCLUSION: We inevitably used sorafenib as an alternative to standard therapy because of the patient's specific circumstances. Individualized strategies for pediatric cancer patients with autism spectrum disorder are needed.

Newly published clinical practice guidelines recommend intracranial pressure (ICP) monitoring in critical care for the management of pediatric acute encephalopathy (pAE), but the utility of ICP monitoring for pAE has been poorly studied. We recently performed direct ICP monitoring for two patients. We observed that although the direct ICP monitoring had clinical benefits with less body weight gain and no vasopressor use in both cases, this monitoring technique is still invasive. Future studies should determine the utility of non-invasive ICP monitoring systems in pAE to further improve the quality of intensive-care management.

Double-chambered left ventricle (DCLV) is a particularly rare congenital entity characterized by the presence of two ventricular cavities separated by an abnormal muscle band. An asymptomatic 15-year-old boy was referred to our hospital because of electrocardiographic (ECG) abnormalities. His initial transthoracic echocardiography (TTE) demonstrated a DCLV with mild left ventricular systolic dysfunction. During a 5-year follow-up period, he remained symptom free with no changes in ECG and conventional TTE findings. However, two-dimensional speckle tracking echocardiography revealed a subtle progressive deterioration of left ventricular systolic function during the 5-year follow-up.

Genetic mutation of the coproporphyrinogen oxidase (CPOX) gene causes either hereditary coproporphyria (HCP) or harderoporphyria. HCP, a rare hepatic porphyria, causes acute attacks after puberty and rarely accompanies cutaneous symptoms. In contrast, harderoporphyria is an erythropoietic porphyria that represents photosensitivity and hemolytic anemia from the neonatal period. In patients with harderoporphyria, the p.Lys404Glu mutation is found in the homozygous or compound heterozygous state with another mutation, and a marked increase in harderoporphyrin is observed. This report describes a neonate with symptoms of erythropoietic harderoporphyria (photosensitivity of the skin, hemolytic anemia, and jaundice). However, the pattern of porphyrin metabolites of feces was consistent with that of typical HCP, not of harderoporphyria. We found a heterozygous, novel, four-base pair deletion in exon 7 of the CPOX gene, although other mutations including the p.Lys404Glu mutation in CPOX were not found. By unknown etiology, our patient had accompanying adrenocortical insufficiency and 46, XY disorders of sex development. Based on genetic mutation of the CPOX gene and information from a previous similar case report, we consider that neonatal-onset HCP is a variant of HCP.
RESUMO
Bordetella pertussis causes life-threatening apnea in infants. Lymphocytosis is an important clue for diagnosis and for determining the severity of pertussis. Antibiotics do not shorten or ameliorate the disease and only decrease the risk of transmission. Antepartum maternal immunization is important for preventing pertussis in infants.
RESUMO
BACKGROUND: Although dosing and sizing of resuscitation drugs and equipment are mostly weight based, time is usually insufficient to weigh critically ill children. Many age-based weight estimation formulae for emergency use have been developed worldwide, but there is no specific formula for Japanese children. The aim of this study was therefore to develop and validate age-based formulae for estimating the bodyweight of children living in Japan. METHODS: A total of 370 980 measurements of bodyweight were obtained from 39 547 participants aged 12-155 months. They participated in a national survey, called the Longitudinal Survey of Babies in the 21st Century, which started in 2001. We created the new original weight estimation formulae for children living in Japan, called the Japanese Pediatric Assessment of Normal weight (JAPAN) formulae, using 75% of measurements that were randomly selected from the total measurements. To check the validity of the formulae, we applied the JAPAN formulae, the Park et al. formula for Korean children, and the commonly used Nelson formula for the remaining 25% of measurements. The mean absolute error and the root mean square error (RMSE) were calculated for each scale. RESULTS: The JAPAN formulae performed better than the two other formulae among Japanese children, with a mean absolute error and RMSE of 0.83 and 1.08 (kg), respectively. The performance of the Park et al. formulae for Korean children was poor for children living in Japan. CONCLUSIONS: The newly developed JAPAN formulae for age-based weight estimation are appropriate for children living in Japan.

Redox regulation has recently been recognized as an important factor in acute illnesses as well as in chronic diseases. It has also become a target for neuroprotection in acute intensive care. Despite its well-known therapeutic effects, therapeutic hypothermia has recently been re-evaluated for its potential use in emergency and critical care medicine. Hypothermia is an undesirable physiological condition that can increase oxidative stress and decrease anti-oxidative potency. However, many studies have shown that under ischemia/reperfusion conditions, therapeutic hypothermia actually suppresses enhanced oxidative stress and maintains or increases anti-oxidative potency. This review provides an overview and outlook for the future of therapeutic hypothermia for neuroprotection from the perspective of redox regulation in patients with post-cardiac arrest syndrome and traumatic brain injury.

BACKGROUND: Vasodilators, such as nitroglycerin, have long been first-line treatments for acute heart failure syndromes (AHFS). Nicorandil is a vasodilator with dual potassium channel opening and nitrate properties. However, there are no randomized controlled studies of intravenous nicorandil safety and efficacy in the urgent phase AHFS. We examined the symptomatic, hemodynamic, and echocardiographic effects and safety, and 60-day clinical outcomes of intravenous nicorandil, in addition to standard therapy, in patients with AHFS in the urgent phase. METHODS: In this prospective, randomized controlled trial, 106 AHFS patients were randomized within one hour of arrival to receive either standard therapy (control group, n=56) or standard therapy plus simultaneous intravenous nicorandil (0.2 mg/kg bolus followed by 0.2 mg/kg/h for 24 h; nicorandil group, n=50). Outcomes were assessed at 60 days. RESULTS: Patients in the nicorandil group exhibited greater improvement of dyspnea as measured by change in a five-point Likert scale compared to those in the control group (after 1 h infusion: p=0.006, 6 h; p<0.001). The nicorandil group also showed significantly improved E/e', an estimate of left ventricular filling pressure, at 1 and 24 h ( p=0.001 and p=0.004, respectively). In addition, intravenous nicorandil therapy was safe and did not cause side effects such as excessive hypotension or reflex tachycardia. However, it did not reduce all-cause mortality and readmission rates at 60 days. CONCLUSIONS: Addition of intravenous nicorandil to standard therapy for urgent phase AHFS improved dyspnea and left ventricular diastolic function but not 60-day outcome.

The urinary cross-linked N-terminal telopeptide of type I collagen (uNTx) levels in infantile osteogenesis imperfecta (OI) have not been well studied. Here we investigated the levels of uNTx in infants with OI and healthy infants. We collected spot urine samples from 30 infants with OI (male/female, 14/16; Sillence classification, I/II/III/IV: 15/3/6/6; age, 5.2±4.4 months) and 120 healthy infants (male/female, 75/45; age, 5.1±4.1 months) for the measurement of uNTx levels. The uNTx levels of the OI infants were significantly lower than those of the healthy infants (mean±SD, 1,363.7±530.1 vs. 2,622.2±1,202.6 nmol BCE/mmol Cr; pï¼0.001). The uNTx levels of the infants with type I OI were significantly lower than those of the age-matched healthy infants, although an overlap was observed between the 2 groups. Among the 1-month-old infants, the uNTx levels of the infants with types I, III or IV OI were significantly lower than those of the healthy infants, without overlap (1,622.5±235.8 vs. 3,781.0±1,027.1 nmol BCE/mmol Cr; pï¼0.001). These results indicate that uNTx levels are significantly lower in infants with OI than in healthy infants, and they suggest that uNTx might be useful as a reference for diagnosing OI.

Estimation methods for pediatric weight have not been evaluated for Japanese children. This study aimed to assess the accuracy of mothers' reports of their children's weight in Japan. We also evaluated potential alternatives to the estimation of weight, including the Broselow tape (BT), Advanced Pediatric Life Support (APLS), and Park's formulae. We prospectively collected cross-sectional data on a convenience sample of 237 children aged less than 10 years who presented to a general pediatric outpatient clinic with their mothers. Each weight estimation method was evaluated using Bland- Altman plots and by calculating the proportion within 10% and 20% of the measured weight. Mothers' reports of weight were the most accurate method, with 94.9% within 10% of the measured weight, the lowest mean difference (0.27kg), and the shortest 95% limit of agreement (ï¼1.4 to 1.9kg). The BT was the most reliable alternative, followed by APLS and Park's formulae. Mothers' reports of their children 's weight are more accurate than other weight estimation methods. When no report of a child's weight by the mother is available, BT is the best alternative. When an aged-based formula is the only option, the APLS formula is preferred.
