We present a case of a male neonate with refractory and persistent neonatal hypoglycaemia not responding to octreotide. On evaluation for hypoglycaemia, his cortisol was within the reference range while the serum insulin concentrations were high. Gallium-68 dotatate scan (GA-68 DOTA) showed diffuse pancreatic involvement. Genetic diagnosis of congenital hyperinsulinaemic hypoglycaemia due to

Objectives. To compare survival by gender and race among transgender and cisgender people enrolled in private insurance in the United States between 2011 and 2019. Methods. We examined Optum’s Clinformatics Data Mart Database. We identified transgender enrollees using claims related to gender-affirming care. Our analytic sample included those we identified as transgender and a 10% random sample of cisgender enrollees. We limited our sample to those 18 years or older who were non-Hispanic Black or White. We identified 18 033 transgender and more than 4 million cisgender enrollees. We fit Kaplan–Meier survival curves and calculated standardized mortality ratios while adjusting for census region. Results. Black transfeminine and nonbinary people assigned male sex at birth were 2.73 times more likely to die than other Black transgender people and 2.38 and 3.34 times more likely than Black cisgender men and women, respectively; similar results were found when White transfeminine and nonbinary people assigned male sex at birth were compared with White cisgender cohorts. Conclusions. Our findings highlight glaring inequities in mortality risks among Black transfeminine and nonbinary people assigned male sex at birth and underscore the need to monitor mortality risks in transgender populations and address the social conditions that increase these risks.

Adrenal insufficiency (AI) in a newborn due to hypothalamic–pituitary–adrenal (HPA) axis suppression after maternal glucocorticoid therapy during pregnancy is a rare condition. We report an AI triggered by a nosocomial infection in a premature newborn. The suspected mechanism was the suppression of the HPA axis due to high doses of maternal glucocorticoid treatment during pregnancy. AI was revealed by recurrent hypoglycaemia and mild hyponatraemia during the neonatal period. His twin brother did not develop AI, showing the variable sensitivity of adrenal suppression after exposure to the same glucocorticoid dose. The affected boy was substituted with hydrocortisone until the age of 2 years. At this age, basal morning values for cortisol and Adrenocorticotropic hormone (ACTH) had normalised. The patient also suffers from galactosaemia. We suggest screening for AI, by testing for hypoglycaemia and hyponatraemia, in newborns who were exposed to high doses of maternal methylprednisolone treatment during the pregnancy and to include galactosaemia in national neonatal screening programmes.

We report the first case of standard therapeutic dose paracetamol for patent ductus arteriosus closure causing acute liver failure in an extremely preterm infant. After 5 days of treatment, he presented with jaundice, acute severe hepatitis and coagulopathy. Treatment with N-acetyl cysteine resulted in full recovery.

Cardiac rhabdomyoma is the most common cardiac tumour in childhood, with a strong genetic association to tuberous sclerosis complex. Although most of the patients remain asymptomatic, a small proportion present with cardiac complications in the early neonatal period. Timely initiation of treatment can potentially reduce disease morbidity, and mammalian target of rapamycin (M-TOR) inhibitors play an effective role in promoting regression of these tumours. A healthy term newborn was diagnosed with a giant congenital cardiac rhabdomyoma at birth. He developed clinical signs of compromised cardiac function and progressive myocardial ischaemia, with echocardiography showing significant dyskinesia. He was treated with M-TOR inhibitors and clinical response was monitored via serial echocardiography. Remarkable regression of the tumour was visibly demonstrated within 4 months of sirolimus treatment. The infant continues to be reviewed by a multidisciplinary team of physicians and monitored for features of tuberous sclerosis complex.

Duodenal stenosis and atresia are some of the most common forms of congenital bowel obstruction. The gold standard approach to treatment is duodenoduodenostomy, while rare, gastrojejunostomy and duodenojejunostomies may still be used. We report a case of a 7-year-old male presenting with annular pancreas with duodenal stenosis that was diagnosed at birth as primary duodenal atresia and repaired by gastrojejunostomy with a Braun enteroenterostomy. Through successful reoperation with dual duodenojejunostomy and subsequent management, we treated the sequelae of the initial repair, including megaduodenum. Regions of duodenal obstruction must have direct anastomotic repair to prevent subsequent issues related to dysmotility. Otherwise, further surgical intervention and long-term medical management, such as the novel strategy reported, may be necessary.

Congenital obstructive uropathy is a rare cause of ascites in infants. Majority of reported cases of genitourinary causes of ascites were due to posterior urethral valve. Here, we report a 6-month-old boy who presented with progressive tense ascites and peritonitis attributed by unilateral left distal ureteric obstruction and acute pyonephrosis. He underwent left nephrostomy placement, after which there was a remarkable improvement of ascites. He then underwent left ureteral diversion procedure a month later with a tentative plan for ureteral reanastomosis in 6 months. To date, there are no reports describing ascites secondary to distal ureteric obstruction beyond the neonatal period. The objective of this case report is to highlight unilateral urinary tract obstruction as a potential cause of transudative ascites. Additionally, the superimposed infection in the obstructed collecting system can lead to acute peritonitis likely due to translocation of bacteria into the peritoneal cavity.

Visceral leishmaniasis (VL) is an infectious disease predominant in countries located in the tropics. The prediction of occurrence of infectious diseases through epidemiologic modeling has revealed to be an important tool in the understanding of its occurrence dynamic. The objective of this study was to develop a forecasting model for the incidence of VL in Maranhão using the Seasonal Autoregressive Integrated Moving Average model (SARIMA). We collected monthly data regarding VL cases from the National Disease Notification System (SINAN) corresponding to the period between 2001 and 2018. The Box-Jenkins method was applied in order to adjust a SARIMA prediction model for VL general incidence and by sex (male or female) for the period between January 2019 and December 2013. For 216 months of this time series, 10,431 cases of VL were notified in Maranhão, with an average of 579 cases per year. With regard to age range, there was a higher incidence among the pediatric public (0 to 14 years of age). There was a predominance in male cases, 6437 (61.71%). The Box-Pierce test figures for overall, male and female genders supported by the results of the Ljung-Box test suggest that the autocorrelations of residual values act as white noise. Regarding monthly occurrences in general and by gender, the SARIMA models (2,0,0) (2,0,0), (0,1,1) (0,1,1) and (0,1,1) (2, 0, 0) were the ones that mostly adjusted to the data respectively. The model SARIMA has proven to be an adequate tool for predicting and analyzing the trends in VL incidence in Maranhão. The time variation determination and its prediction are decisive in providing guidance in health measure intervention. Resumo A leishmaniose visceral (LV) é uma doença de natureza infecciosa, predominante em países de zonas tropicais. A predição de ocorrência de doenças infecciosas através da modelagem epidemiológica tem se revelado uma importante ferramenta no entendimento de sua dinâmica de ocorrência. O objetivo deste estudo foi desenvolver um modelo de previsão da incidência da LV no Maranhão usando o modelo de Média Móvel Integrada Autocorrelacionada Sazonal (SARIMA). Foram coletados os dados mensais de casos de LV através do Sistema de Informação de Agravos de Notificação (SINAN) correspondentes ao período de 2001 a 2018. O método de Box-Jenkins foi aplicado para ajustar um modelo de predição SARIMA para incidência geral e por sexo (masculino e feminino) de LV para o período de janeiro de 2019 a dezembro de 2023. Durante o período de 216 meses dessa série temporal, foram registrados 10.431 casos de LV no Maranhão, com uma média de 579 casos por ano. Em relação à faixa etária, houve maior registro no público pediátrico (0 a 14 anos). Houve predominância do sexo masculino, com 6437 casos (61,71%). Os valores do teste de Box-Pierce para incidência geral, sexo masculino e feminino reforçados pelos resultados do teste Ljung-Box sugerem que as autocorrelações de resíduos apresentam um comportamento de ruído branco. Para incidência mensal geral e por sexo masculino e feminino, os modelos SARIMA (2,0,0) (2,0,0), (0,1,1) (0,1,1) e (0,1,1) (2, 0, 0) foram os que mais se ajustaram aos dados, respectivamente. O modelo SARIMA se mostrou uma ferramenta adequada de previsão e análise da tendência de incidência da LV no Maranhão. A determinação da variação temporal e sua predição são determinantes no norteamento de medidas de intervenção em saúde.

Cross-sectional studies have shown that greater friendship satisfaction in adulthood is associated with many positive outcomes (Chopik, 2017; Gillespie, Frederick, et al., 2015). However, the developmental antecedents of satisfaction with close friends in adulthood have not been examined using prospective data. We do not know, for example, whether certain key experiences early in life, such as infant attachment security versus insecurity or the quality of maternal sensitivity, prospectively predict the degree of satisfaction with close friends in adulthood. We also do not know whether other salient experiences, such as the degree of peer competence in childhood or friendship security in adolescence, mediate relations between early life attachment and/or maternal sensitivity and adult friendship satisfaction. Leveraging data from the Minnesota Longitudinal Study of Risk and Adaption, we examined four developmental models containing these theoretically relevant antecedents of friendship satisfaction at age 32. The sample was approximately evenly split by gender (female = 82, male = 76), with the following ethnic distribution: White = 67.1%, Black = 8.9%, mixed race = 18.4%, other = 5.6%. All participants were born to mothers living below the poverty line at birth but on average were lower middle class by age 32. We found that the model containing direct paths from infant attachment security versus insecurity and from the quality of maternal sensitivity to friendship satisfaction at age 32 provided the best fit, suggesting that early parent-child relationships provide a foundation for later adult relationships with close friends. The implications of these findings are discussed. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

We describe a 9-day-old baby with coarctation of the aorta who required urgent resuscitation including intubation and cardiac compressions. Despite the commencement of prostaglandin E1 (PGE1) to reopen the ductus arteriosus via the intraosseous route, postductal saturations remained unrecordable for a further 45 min. Within 3 min of administration of PGE1 via an umbilical venous catheter (UVC), saturations were recordable at 92%. UVC access was the sentinel intervention that irrevocably altered the clinical prognosis. This baby boy has survived with excellent neurodevelopmental outcome. Clinicians are less familiar with UVCs outside of the newborn period. Our data demonstrate successful placement in neonates up to 28 days of age. We hope this case encourages clinicians to consider the UVC as first-line central venous access in collapsed neonates. In cases of suspected left heart obstruction, we argue that UVCs are the optimal route.

While considerable research has examined gender development in middle childhood, little longitudinal work has been conducted at this time to indicate whether, for example, youth who show more or less gender conformity at one point continue to do so later. The present study investigated the consistency of gender identity and preferences for gender-stereotypical toys, clothing, and same-gender peer preferences among groups of transgender youth (

Premature neonates are frequently transfused red blood cells (RBCs) or platelets to raise hemoglobin or platelet counts. However, these transfusions may have unintended effects on the immune system. This review will summarize the newest discoveries on the immunologic effects of RBC and platelet transfusions in neonates, and their potential impact on neonatal outcomes.Neonatal RBC transfusions are associated with increases in plasma pro-inflammatory cytokines, but recent findings suggest sex-specific differential responses. At least one cytokine (monocyte chemoattractant protein-1) rises in females receiving RBC transfusions, but not in males. These inflammatory responses correlate with poorer neurodevelopmental outcomes in heavily transfused female infants, while preterm male infants seem to be more sensitive to severe anemia. Platelet transfusions in preterm neonates are associated with increased neonatal mortality and morbidity. The underlying mechanisms are unknown, but likely related to the immune/inflammatory effects of transfused platelets. Adult platelets are different from neonatal platelets, with the potential to be more pro-inflammatory. Early preclinical data suggest that platelet transfusions alter the neonatal systemic inflammatory response and enhance immune cell migration.RBC and platelet transfusions alter neonatal immune and inflammatory responses. Their pro-inflammatory effects might worsen neonatal disease or affect neurodevelopmental outcomes.

Objectives. To assess the impact of the COVID-19 pandemic on immunization services across the life course. Methods. In this retrospective study, we used Michigan immunization registry data from 2018 through September 2020 to assess the number of vaccine doses administered, number of sites providing immunization services to the Vaccines for Children population, provider location types that administer adult vaccines, and vaccination coverage for children. Results. Of 12 004 384 individual vaccine doses assessed, 48.6%, 15.6%, and 35.8% were administered to children (aged 0–8 years), adolescents (aged 9–18 years), and adults (aged 19‒105 years), respectively. Doses administered overall decreased beginning in February 2020, with peak declines observed in April 2020 (63.3%). Overall decreases in adult doses were observed in all settings except obstetrics and gynecology provider offices and pharmacies. Local health departments reported a 66.4% decrease in doses reported. For children, the total number of sites administering pediatric vaccines decreased while childhood vaccination coverage decreased 4.4% overall and 5.8% in Medicaid-enrolled children. Conclusions. The critical challenge is to return to prepandemic levels of vaccine doses administered as well as to catch up individuals for vaccinations missed.

Background: Moebius syndrome is a disorder characterized by facial and abducens nerve paralysis. Patients can present a wide range of upper extremity malformations. Literature focused on orthopedic manifestations of Moebius syndrome shows variability in the prevalence and clinical presentation of upper extremity anomalies. The aim of this work is to evaluate the prevalence of upper extremity malformations in patients with Moebius syndrome, clarify its various clinical presentations, and present treatment strategies for their management. Methods: This is a retrospective, cross-sectional study including patients with Moebius syndrome and upper extremity malformations between 2012 and 2019. Data include demographic characteristics, Moebius syndrome subtype, type of malformation, affected extremity, and surgical procedures underwent. Quantitative data were recorded as mean (standard deviation [SD]), and qualitative data were expressed in terms of totals and percentages. Statistical association between Moebius syndrome subtype and development of upper extremity anomalies was evaluated using binary logistic regression. Results: Twenty-five out of 153 patients (16.3%) presented upper extremity malformations (48% male). Mean age of presentation was 9.08 ± 9.43 years. Sixty-eight percent of the malformations were unilateral. The most common presentations included Poland syndrome and simple syndactyly with 8 cases each (32%), followed by 5 cases of brachysyndactyly (20%), 3 cases of amniotic band syndrome (12%), and 1 case of cleft hand (4%). No statistical association was found between Moebius syndrome subtype and odds ratio for development of upper extremity anomalies. Thirteen patients (52%) underwent reconstructive procedures. Conclusion: Poland syndrome and syndactyly are the most common anomalies in patients with Moebius syndrome. Patients may present with a wide range of hand malformations, each patient should be carefully evaluated in order to determine whether surgical treatment is needed and to optimize rehabilitation protocols.

Background: To determine if the “unaffected” hand in children with hemiplegic cerebral palsy (CP) is truly unaffected. Methods: We performed a retrospective review of manual dexterity as measured by the Functional Dexterity Test (FDT) in 66 children (39 boys, 27 girls, mean age: 11 years 4 months) with hemiplegic CP. Data were stratified by Manual Ability Classification System (MACS) level, birth weight, and gestational age at birth, and compared with previously published normative values. Results: The FDT speed of the less affected hand is significantly lower than typically developing (TD) children ( P < .001). The development of dexterity is significantly lower than TD children (0.009 vs. 0.036 pegs/s/year, P < .001), with a deficit that increases with age. MACS score, birth weight, and age at gestation are not predictors of dexterity. The dexterity of the less affected hand is poorly correlated with that of the more affected hand. Conclusions: Both dexterity and rate of fine motor skill acquisition in the less affected hand of children with hemiplegic CP is significantly less than that of TD children. The less affected hand should be evaluated and included in comprehensive treatment plans for these children.

ImportanceSex-specific differences in the commonly used cardiac biomarkers high-sensitivity cardiac troponin (hs-cTn) and N-terminal pro–brain natriuretic peptide (NT-proBNP) are apparent. There is an absence of medical literature delineating the concentration differences for these biomarkers in transgender individuals without cardiac disease.ObjectiveTo determine the distribution of hs-cTn and NT-proBNP in healthy transgender people.Design, Setting, and ParticipantsIn this cross-sectional prospective study, healthy transgender individuals prescribed testosterone or estradiol for 12 months or more were recruited from internal medicine and primary care clinics that specialize in transgender medical care between November 1, 2017, and July 1, 2018.ExposuresTestosterone or estradiol for 12 months.Main Outcomes and MeasuresConcentrations for hs-cTnI (troponin I), hs-cTnT (troponin T), and NT-proBNP were measured.ResultsTransgender people prescribed testosterone (n = 79; mean [SD] age, 28.8 [7.8] years) or estrogen (n = 93; mean [SD] age, 35.1 [11.7] years) were recruited. The concentration of hs-cTn was significantly higher in transgender men relative to transgender women. For Abbott hs-cTnI levels, the median (IQR) concentration observed in transgender men and women was 0.9 (0.6-1.7) ng/L and 0.6 (0.3-1.0) ng/L, respectively. Results were similar across 2 additional hs-cTn assays. In contrast, NT-proBNP level was higher in transgender women. The median (IQR) NT-proBNP concentration was significantly higher in transgender women ( 49 [32-86] ng/L) than in transgender men (17 [13-27] ng/L).Conclusions and RelevanceFindings of this cross-sectional study suggest that the differences in concentration for hs-cTn and NT-proBNP between transgender men and women were similar to what is observed between cisgender men and women. Sex hormones, rather than sex assigned at birth, may be a stronger driver of the observed concentration differences between healthy men and women for biomarkers of cardiac disease.

ImportanceTransgender and nonbinary (TGNB) adolescents and young adults (AYA) designated female at birth (DFAB) experience chest dysphoria, which is associated with depression and anxiety. Top surgery may be performed to treat chest dysphoria.ObjectiveTo determine whether top surgery improves chest dysphoria, gender congruence, and body image in TGNB DFAB AYA.Design, Setting, and ParticipantsThis is a nonrandomized prospective cohort study of patients who underwent top surgery between December 2019 and April 2021 and a matched control group who did not receive surgery. Patients completed outcomes measures preoperatively and 3 months postoperatively. This study took place across 3 institutions in a single, large metropolitan city. Patients aged 13 to 24 years who presented for gender-affirming top surgery were recruited into the treatment arm. Patients in the treatment arm were matched with individuals in the control arm based on age and duration of testosterone therapy.ExposuresPatients in the surgical cohort underwent gender-affirming mastectomy; surgical technique was at the discretion of the surgeon.Main Outcomes and MeasuresPatient-reported outcomes were collected at enrollment and 3 months postoperatively or 3 months postbaseline for the control cohort. The primary outcome was the Chest Dysphoria Measure (CDM). Secondary outcomes included the Transgender Congruence Scale (TCS) and Body Image Scale (BIS). Baseline demographic and surgical variables were collected, and descriptive statistics were calculated. Inverse probability of treatment weighting (IPTW) was used to estimate the association of top surgery with outcomes. Probability of treatment was estimated using gradient-boosted machines with the following covariates: baseline outcome score, age, gender identity, race, ethnicity, insurance type, body mass index, testosterone use duration, chest binding, and parental support.ResultsOverall, 81 patients were enrolled (mean [SD] age, 18.6 [2.7] years); 11 were lost to follow-up. Thirty-six surgical patients and 34 matched control patients completed the outcomes measures. Weighted absolute standardized mean differences were acceptable between groups with respect to body mass index, but were not comparable with respect to the remaining demographic variables baseline outcome measures. Surgical complications were minimal. IPTW analyses suggest an association between surgery and substantial improvements in CDM (–25.58 points; 95% CI, –29.18 to –21.98), TCS (7.78 points; 95% CI, 6.06-9.50), and BIS (–7.20 points; 95% CI, –11.68 to –2.72) scores.Conclusions and RelevanceTop surgery in TGNB DFAB AYA is associated with low complication rates. Top surgery is associated with improved chest dysphoria, gender congruence, and body image satisfaction in this age group.

Bronchopulmonary dysplasia (BPD) is a disease with a significant sexual dimorphism where males have a disadvantage compared with their female counterparts. Although mechanisms behind this sexual dimorphism are poorly understood, sex differences in angiogenesis have been identified as one possible source of the male disadvantage in BPD. Pulmonary angiogenesis was assessed in vitro using a bead sprouting assay with pooled male or female human pulmonary microvascular endothelial cells (HPMECs, 18-19 wk gestation, canalicular stage of human lung development) in standard (sex-hormone containing) and hormone-stripped medium. We identified sex-specific phenotypes in angiogenesis where male HPMECs produce fewer but longer sprouts compared with female HPMECs. The presence of sex hormones from standard culture medium modifies the male HPMEC phenotype with shorter and fewer sprouts but does not influence the female phenotype. Using a conditioned medium model, we further characterized the influence of the sex-specific secretome. Male and female HPMECs secrete factors that increase the maximum length of sprouts in female, but not male HPMECs. The presence of sex hormones abolishes this response. The male HPMEC secretome inhibits angiogenic sprouting in male HPMECs in the absence of sex hormones. Taken together, these results demonstrate that the pulmonary endothelial cell phenotypes are influenced by sex hormones and sex-specific secreted factors in a sex-dependent manner.

There is no separate course in the medical curriculum summarizing all aspects of human reproduction in most medical school curricula. At the same time, such a course would logically connect knowledge from clinical embryology and assisted reproduction, encompassing the issue of female and male infertility, mechanisms of birth defect formation, their prenatal diagnosis and subsequent specialized neonatal care. The aim of a wide team of university teachers comprising embryologists, gynecologists, neonatologists, endocrinologists, geneticists and others was to create and implement a new course entitled "Clinical Embryology and Reproductive Medicine" into the fourth-year curriculum of the study program General Medicine at the Faculty of Medicine, Comenius University in Bratislava. There has been a great interest in the course, as evidenced by the number of medical students enrolled. The lecture syllabuses have been divided into several thematic areas: 1) Clinical embryology including a laboratory part of assisted reproduction, 2) Cause and treatment options of female and male infertility, 3) A comprehensive view of the issue of birth defects, 4) The issue of preconception education, prenatal and childbirth training, family planning, 5) Reproductive immunology and endocrinology. Despite the complexity of human reproduction being a mainstay of gynecology and obstetrics, it is underemphasized in the medical school curricula worldwide. It is often reflected in shorter hospital / practical trainings during undergraduate studies and lower requirements at the final exam. Therefore, as students almost unanimously valued, this new course is extremely helpful in preparing for the final state exam.

BACKGROUND: Despite the known effect of hyperbilirubinemia in neonates, the effect of phototherapy on electroencephalography (EEG) remains unknown. Therefore, we aimed to determine the alteration of electroencephalography in infants with hyperbilirubinemia before and after phototherapy. METHODS: This cross-sectional study was performed on infants of≥35 weeks of gestation with hyperbilirubinemia. Information including age, sex, birth weight, hemoglobin levels, and treatment measures was recorded. In all studied infants, an EEG was performed before (in the first eight hours of hospitalization) and after treatment (after phototherapy or blood transfusion). The required duration of phototherapy, hospitalization and adverse effects were assessed then EEG of the neonates was compared before and after treatment. RESULTS: A total of 52 infants (44% female and 56% male) were included in this study. Mean gestational age, weight, and bilirubin were 38.6±1.53 weeks, 3150±625 g, and 23.87±4.36 mg/dl, respectively. The most common findings before phototherapy were Frontal Theta (21 patients, 40.4 percent) and Delta Brush (14 patients, 26.9%), while the most common findings after phototherapy were Frontal Theta (20 patients, 38.5%) and Delta Brush (19 patients, 36.5%). Mean±SD of bilirubin in infants with and without Delta Brush was 21.30±1.67 mg/dl and 19.95±0.94 mg/dl, respectively. CONCLUSIONS: Hyperbilirubinemia in newborns may be linked to altered EEG findings. After phototherapy, the Frontal theta was reduced, but the Delta brush was intensified. Bilirubin levels were higher in infants with Delta Brush in their EEG compared to infants without this finding.

Age and sex need to be considered in the establishment of reference intervals (RIs), especially in early life when there are dynamic physiological changes. Since data for important biomarkers in healthy neonates and infants are limited, particularly in Iranian populations, we have determined age-specific RIs for 7 laboratory biochemical parameters. This cross-sectional study comprised a total of 344 paediatric participants (males: 158, females: 186) between the ages of 3 days and 30 months (mean age: 12.91 ± 7.15 months). Serum levels of creatinine, urea, uric acid, calcium, phosphate, vitamin D and high-sensitivity C-reactive protein (hs-CRP) were measured using an Alpha classic-AT plus auto-analyser. We determined age-specific RIs using CLSI Ep28-A3 and C28-A3 guidelines. No sex partitioning was required for any of the biomarkers. Age partitioning was required for kidney function tests and phosphate. The serum concentration of urea and creatinine increased with age, while phosphate and uric acid decreased with age. Age partitioning was not required for serum calcium, vitamin D, and hs-CRP, which remained relatively constant throughout the age range. Age-specific RIs for 7 routine biochemical markers were determined to address critical gaps in RIs in early life to help improve clinical interpretation of blood test results in young children, including neonates. Established age partitions demonstrate the biochemical changes that take place during child growth and development. These novel data will ultimately better disease management in the Iranian paediatric population and can be of value to clinical and hospital laboratories with similar populations.

The Newborn Infant Parasympathetic Evaluation (NIPE) index is an instrument that enables continuous, fast and objective assessment of neonatal discomfort. The aim of the study was to analyse changes in NIPE values after performance of blood draws and the factors involved in this variation.We conducted a prospective observational study. We included infants admitted to the neonatal intensive care unit between June and December 2021 who underwent blood draws. We recorded demographic data, aspects related to the procedure, the NIPE index and the heart rate at baseline and 1, 2, 3, 4, 5, 10 and 15 min after the procedure.The study included 86 records for 49 patients. In the first 4 min after the procedure, there was a significant decrease in the NIPE index, with a maximum decrease of 22.8% relative to baseline and the nadir at 2.79 min. The decrease in NIPE values was greater in infants born preterm, male, with lower 5-min Apgar scores and following procedures that had been performed previously, after caesarean section or in the morning. There were no differences when the blood draw was obtained during kangaroo care. The correlation between the NIPE index and the heart rate was weak.After a painful procedure, such as a blood draw, the NIPE monitor showed a significant decrease in the first 4 min, which was more pronounced in preterm infants, in repeated procedures or after caesarean delivery. The NIPE index could help identify infants experiencing acute procedural pain, complementing clinical rating scales.

Pancreatic neuroendocrine tumors (P-NETs) are highly heterogeneous with wide spectrum of biological behaviors and growth patterns. Here, we aimed to assess the impact of tumor grading on P-NETs prognosis and survival outcomes.Patients with P-NET were recruited to determine correlations between grades and clinicopathological factors, survival outcomes and prognostic factors.A total of 152 patients with P-NETs were enrolled. G1 P-NET were associated with significantly lower rates of perineural invasion, lymphovascular invasion, lymph node involvement and distant metastasis. The pancreatic head was the most common location of P-NETs. The 1-year, 5-year and 10-year overall survival rates of the patients were 94.4%, 89.1% and 78.8%, respectively. Majority of pancreatic neuroendocrine carcinoma (P-NEC) were unresectable (90.9%), and P-NECs patients had poor survival rates (1-year, 20% and no 5-year). Male sex, tumor size ≥2.5 cm, perineural invasion, lymph node invasion, metastasis, and advanced stage were significantly associated with poorer survival outcomes. Tumor grade and sex were independent survival predictors. Moreover, tumor grade was the most powerful prognostic factor.Tumor grade, sex, perineural invasion, tumor size, lymph node involvement, metastasis, and stage are survival predictors for patients with P-NETs. Tumor grade is the most powerful independent prognostic factor.

We reviewed the long-term outcome of children with hypertrophic cardiomyopathy (HCM) based on the type.We reviewed the medical records of 100 patients (male 54 female 46) with HCM at our hospital between 1977 and 2015. The survival and cardiac event-free survival rates were calculated by the Kaplan-Meier method.The age at the time of the diagnosis ranged from 0 to 15 years with a median of 8 years. The number of patients with Noonan syndrome and hypertrophic obstructive cardiomyopathy (HOCM), idiopathic HCM (i-HCM), and secondary HCM (s-HCM) was 13, 13, 65, and 9 respectively. A dilated phase of HCM occurred in 24 patients. Nineteen (79 %) of the 24 patients died of heart failure, and two underwent a heart transplantation. Eight (33 %) of the 24 patients had s-HCM. The median age when a dilated phase occurred was 15 years old, and the median interval from the initial diagnosis to the dilated phase was 8 years. The median time from the diagnosis of a dilated phase to death was 1.6 years. Sudden death and implantable cardioverter defibrillator implantations occurred in 6 and 11 patients at around 15 years old, respectively. The 20-year survival rates were as follows: Noonan syndrome 84 %; HOCM 82 %; i-HCM 71 %; and s-HCM 17 %. Overall, the survival rates at 10, 20, and 30 years were 83 % (95 % confidence interval 73-89), 69 % (58-78), and 63 % (50-74), respectively. The overall cardiac event-free survival rates at 10, 20, and 30 years were 57 % (47-67), 39 % (31-50), and 32 % (21-44), respectively.The long-term outcome in children with HCM was poor, and the outcome of s-HCM was very poor. The occurrence of a dilated phase worsened the outcome in HCM patients. Sudden death and d-HCM often occurred at around 15 years old.

Introduction To investigate the current experience of the ARM-Net Consortium in the management of epididymo-orchitis (EO) in patients with anorectal malformations (ARMs), and to identify specific risk factors and the need for urological care involvement. Materials and Methods We retrospectively collected data of EO in patients with ARM between 2015 and 2019. Data on urological aspects, ARM type, surgical approach, associated anomalies, diagnosis, and treatment of EO were collected and analyzed. Results Twenty-nine patients were reported by 12 centers. Twenty-six patients with EO (90%) had ARM with a rectourinary fistula. Median age at first EO was 2 years (range: 15 days–27 years). Twenty patients (69%) experienced multiple EO, and 60% of recurrences were ipsilateral. Associated urological anomalies included vesicoureteral reflux (48%), urethral anomalies (41%), neurogenic bladder (41%), and ectopic vas (10%). A positive urine culture during EO was present in 69%. EO was treated with antibiotics (90%), limiting surgical exploration to 14%. Prevention of recurrences included surgery (bulking agents 15%, vasectomy 15%, and orchiectomy 5%) and antibiotic prophylaxis (20%). Conclusion Urologists may encounter patients with EO in ARM patients, frequently with positive urine culture. An appropriate urologic work-up for most ARM patients is necessary to identify and treat underlying risk factors. A practical scheme for the work-up is suggested for a close collaboration between pediatric surgeons and urologists.

The incidence of pediatric hospital-acquired venous thromboembolism (HA-VTE) has increased over time. Congenital heart disease (CHD) as a co-morbidity has been demonstrated to significantly increase HA-VTE risk among hospitalized children.To identify specific risks factors for the development of HA-VTE in hospitalized children with CHD.This retrospective case-control study included hospitalized participants aged 0-21 years within the Children's Hospital Acquired Thrombosis (CHAT) Consortium Registry with a co-morbidity of CHD. Participants with HA-VTE and non-VTE controls with a past medical history of CHD were selected from the CHAT Registry and data regarding multiple clinical variables were extracted. These variables were then analyzed to assess their association with HA-VTE development.Three hundred and thirty-three participants with a co-morbidity of CHD were identified, comprising 275 HA-VTE cases and 58 controls. Median age for HA-VTE cases was 0.4 (IQR = 0-2.6) years compared to 3.4 (IQR = 0.7-6.5) for controls. Male participants were predominant in both groups (57.5 % HA-VTE cases vs 51.7 % controls). Multivariable analysis identified prior recent hospitalization (OR = 4.12, 95%CI = 1.66-10.24), intensive care unit (ICU) admission (OR = 3.29, 95 % CI = 1.15-9.40), and CVC placement (OR = 9.14, 95 % CI = 3.38-24.72) as significant risk factors for HA-VTE in subjects with CHD.ICU admission, CVC placement, and prior hospitalization were identified as statistically significant predictors associated with HA-VTE development in hospitalized children with history of CHD. Prospective studies are needed to validate these results and help develop strategies to mitigate HA-VTE development in these patients.

Background Assessment of appropriate brain myelination on T1- and T2-weighted MRI scans is based on gestationally corrected age (GCA) and requires subjective visual inspection of the brain with knowledge of normal myelination milestones. Purpose To develop a convolutional neural network (CNN) capable of estimating neonatal and infant GCA based on brain myelination on MRI scans. Materials and methods In this retrospective study from one academic medical center, brain MRI scans of patients aged 0-25 months with reported normal myelination were consecutively collected between January 1995 and June 2019. The GCA at MRI was manually calculated. After exclusion criteria were applied, T1- and T2-weighted MRI scans were preprocessed with skull stripping, linear registration

The world has been experiencing an opioid epidemic for over 20 years, and rates of use and overdose among women, including during pregnancy, have risen markedly. Women receive more prescriptions for opioids compared to men. Data suggest that 20% of women filled at least one prescription for an opioid during their pregnancy, and the prevalence of prenatal exposure averaged 14%. Opioid use by women, especially during pregnancy and while breastfeeding, and management and treatment is complex for healthcare providers, especially related to methadone treatment, pain management during labour, neonatal opioid withdrawal syndrome, nutritional issues and maternal withdrawal. Opioid use during pregnancy has been associated with maternal, foetal and infant complications, and overdose has become a leading cause of death in post-partum women in some countries. Universal screening for opioid use disorder (OUD) is recommended in pregnancy, and prevention and treatment programs that meet the specific needs of women are important to understand and consider as the world continues to try to anticipate and respond to the realities of the opioid epidemic.

Background: In the Netherlands, treatment with puberty suppression is available to transgender adolescents younger than age 18 years. When gender dysphoria persists testosterone or oestradiol can be added as gender-affirming hormones in young people who go on to transition. We investigated the proportion of people who continued gender-affirming hormone treatment at follow-up after having started puberty suppression and gender-affirming hormone treatment in adolescence. Methods: In this cohort study, we used data from the Amsterdam Cohort of Gender dysphoria (ACOG), which included people who visited the gender identity clinic of the Amsterdam UMC, location Vrije Universiteit Medisch Centrum, Netherlands, for gender dysphoria. People with disorders of sex development were not included in the ACOG. We included people who started medical treatment in adolescence with a gonadotropin-releasing hormone agonist (GnRHa) to suppress puberty before the age of 18 years and used GnRHa for a minimum duration of 3 months before addition of gender-affirming hormones. We linked this data to a nationwide prescription registry supplied by Statistics Netherlands (Centraal Bureau voor de Statistiek) to check for a prescription for gender-affirming hormones at follow-up. The main outcome of this study was a prescription for gender-affirming hormones at the end of data collection (Dec 31, 2018). Data were analysed using Cox regression to identify possible determinants associated with a higher risk of stopping gender-affirming hormone treatment. Findings: 720 people were included, of whom 220 (31%) were assigned male at birth and 500 (69%) were assigned female at birth. At the start of GnRHa treatment, the median age was 14·1 (IQR 13·0–16·3) years for people assigned male at birth and 16·0 (14·1–16·9) years for people assigned female at birth. Median age at end of data collection was 20·2 (17·9–24·8) years for people assigned male at birth and 19·2 (17·8–22·0) years for those assigned female at birth. 704 (98%) people who had started gender-affirming medical treatment in adolescence continued to use gender-affirming hormones at follow-up. Age at first visit, year of first visit, age and puberty stage at start of GnRHa treatment, age at start of gender-affirming hormone treatment, year of start of gender-affirming hormone treatment, and gonadectomy were not associated with discontinuing gender-affirming hormones. Interpretation: Most participants who started gender-affirming hormones in adolescence continued this treatment into adulthood. The continuation of treatment is reassuring considering the worries that people who started treatment in adolescence might discontinue gender-affirming treatment. Funding: None.

Background. Neonatal sepsis is a leading cause of morbidity and mortality in low-and middle-income countries (LMICs). There are several sophisticated biomarkers; however, they are still insufficient in precision. In this perspective, our study aims to search for a pragmatic diagnostic biomarker in the age category. Methods. A cross-sectional study was conducted over six months(April-September 2018). All neonates with a diagnosis of probable sepsis were included. Logistic regression analysis of demographic variables was done to elucidate any association with confirmed sepsis cases. The median with interquartile range (IQR)] and mean with standard deviation (SD) were calculated, and then compared. The area under the receiver operating characteristic curve (AUROC) of the commonly opted biomarker tests [distribution width of red blood cells (RDW) and platelets(PDW), mean platelet volume(MPV), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR)] was compared to the culture-confirmed case. Results. Of the 171 suspected sepsis subjects, we discovered a significant burden of newborn sepsis, with 18.7% of cases being culture-confirmed. 66 Early-onset sepsis(EOS) and 105 Late-onset sepsis(LOS) probable sepsis cases were enrolled. A higher incidence was revealed among male infants 24(14%) compared to females 8(4.7%). On logistic regression analysis, preterm birth [odds ratio (OR): 10.9, 95% confidence interval (CI): 4.5-26.9] and low birth weight (OR: 6.5, 95% CI: 2.4-17.9) were significantly associated. Coagulase-negative Staphylococcus aureus (CoNS) (n =6) among gram-positive, and Pseudomonas aeruginosa (n =6) was among gram-negative, were the leading etiologies. Escherichia coli (n =3) was the predominant bacteria in EOS subjects, while Pseudomonas aeruginosa (n =6) among LOS. Median interquartile range(IQR): platelet count 144.5(99-192), red cell distribution width 18(16.9-20), CRP 6(3-18.3); and mean ± SD: MPV (11.7 ± 1.7); PDW (15.2 ± 3.5) were attained, among confirmed cases. The AUROC, of biomarker tests was attained in the order: PDW(0.86) > MPV(0.81) > RDW(0.76) > CRP(0.67) > ESR(0.59); similarly, the cut-off order was >11.2, >10.4, >16.8, >2.9, >4.5, respectively. Conclusions. Our finding shows an increment in the width and volume of RBCand platelet: RDW, MPV, and PDW have a diagnostic role in neonatal sepsis.

Reports on the risk and prognosis of breast cancer in relation to the sex of a child have been conflicting. Since medical sciences play an important role in informing sociocultural understandings of health and illness, evidence-based studies have the potential to foster or counter stigma and shape social attitudes toward a newborn’s sex.To pool all available evidence to provide the highest level of evidence on the association between the sex of the first child and breast cancer risk or prognosis.Systematic review and meta-analyses.A comprehensive search using three databases was conducted from inception until May 2020. Titles and abstracts of all papers identified were independently screened by two authors. Data extraction and quality assessment were also performed independently by two researchers. The breast cancer risk was quantified using the odds ratio, and the prognosis (i.e., mortality) was measured using the risk ratio.In the meta-analysis, 11 studies with more than 1 million participants were included. The pooled estimate from the five studies on risk and the six studies on prognosis were odds ratio 0.99 (95% confidence interval, 0.95-1.03) and risk ratio 1.00 (95% confidence interval, 0.80-1.26), respectively.When we pooled all available evidence, the sex of the firstborn child was neither associated with risk nor prognosis in breast cancer. Clinically, our findings are reassuring and important, especially in light of previous studies that recommended differential treatment and counseling based on the sex of the first child. Socially, our findings challenge conventional social stereotypes that regard male children as biologically superior to female children.

Cor Triatriatum Sinister (CTS) is a rare congenital anomaly with an estimated incidence of 0.4%, resulting from abnormal left atrial septation. It may present in isolation or in association with other heart defects. High percentage of patients require surgery with low mortality and recurrence rates. CTS has been classified in the past however we aim to describe a case series with more comprehensive and inclusive classification.This was a single-center retrospective cohort study of 16 children with the diagnosis of CTS between 2000 and 2020. Medical records were reviewed for clinical presentations, hospital, and postoperative courses.Sixteen patients (63% female), with a median age at diagnosis of 4.3 months, five (31%) were neonates. Six (38%) had isolated CTS, two (13%) with functional single ventricle (SV), and the remaining eight patients (50%) had other associated heart defects (septal defects in three, coarctation of the aorta in another three, and anomalous pulmonary venous connections in three). Eight patients (50%) presented with obstructed CTS. Twelve patients (75%) underwent surgical intervention. Mortality occurred in three patients (19%) with two surgical (one with total anomalous pulmonary venous connection and another with SV) and one nonsurgical (septal defect with Fanconi anemia). The surgical median follow up was 4.7 years. Recurrence of the membrane occurred in two patients (17%).This study showed good long-term outcomes for patients with isolated and complex CTS. Complete and proper classification of CTS ensures appropriate diagnosis, surgical planning, and better family counseling which may correlate with outcomes.

To present the results of hypospadias repair in the absence of preputial skin following neonatal circumcision, and the analyses of surgical techniques and predictors of procedural success.Records of all children who underwent hypospadias repair between 10/1999 and 12/2018 were retrospectively reviewed. All of those who underwent neonatal circumcision prior to surgery were included. Patients with any prior penile reconstruction surgery and those with the megameatus intact prepuce variant were excluded. The primary endpoint was the need for reoperation.A total of 69 patients with a history of neonatal circumcision underwent surgical reconstruction of hypospadias during the study period. Their mean age at surgery was 14 months (interquartile range [IQR] 9,22). Forty-five cases (65%) involved distal hypospadias, and ventral curvature was present in 24 (35%). Dartos flaps were harvested from the dorsal aspect in 37/58 (64%) patients and from the ventral aspect in 21/58 (36%). Twenty-two patients (22/69, 32%) required reoperation after a median follow-up of 9 years (IQR 6,13). Indications for revision surgery included urethral fistula (n = 16, 22%), meatal stenosis (n = 5, 7%), and skin redundancy (n = 1). Ventral curvature (odds ratio [OR] 3.5, p = 0.02) and higher grades of hypospadias. (OR 3.3, p = 0.03) had a higher probability of reoperation (univariate logistic regression).Hypospadias repair following neonatal circumcision in the absence of preputial skin is a challenging reconstruction. The reoperation rate in our cohort was 30%, similar to reoperative hypospadias surgery. Parents of newborns diagnosed with hypospadias should be encouraged to refrain from pre surgical neonatal circumcision.Treatment study, level IV.

Analysing trends and levels of the burden of disease at the national level can mask inequalities in health-related progress in lower administrative units such as provinces and districts. We used results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 to analyse health patterns in Indonesia at the provincial level between 1990 and 2019. Long-term analyses of disease burden provide insights on Indonesia's advance to universal health coverage and its ability to meet the United Nations Sustainable Development Goals by 2030.We analysed GBD 2019 estimated cause-specific mortality, years of life lost (YLLs), years lived with disability (YLDs), disability-adjusted life-years (DALYs), life expectancy at birth, healthy life expectancy, and risk factors for 286 causes of death, 369 causes of non-fatal health loss, and 87 risk factors by year, age, and sex for Indonesia and its 34 provinces from 1990 to 2019. To generate estimates for Indonesia at the national level, we used 138 location-years of data to estimate Indonesia-specific demographic indicators, 317 location-years of data for Indonesia-specific causes of death, 689 location-years of data for Indonesia-specific non-fatal outcomes, 250 location-years of data for Indonesia-specific risk factors, and 1641 location-years of data for Indonesia-specific covariates. For subnational estimates, we used the following source counts: 138 location-years of data to estimate Indonesia-specific demographic indicators; 5848 location-years of data for Indonesia-specific causes of death; 1534 location-years of data for Indonesia-specific non-fatal outcomes; 650 location-years of data for Indonesia-specific risk factors; and 16 016 location-years of data for Indonesia-specific covariates. We generated our GBD 2019 estimates for Indonesia by including 1 915 207 total source metadata rows, and we used 821 total citations.Life expectancy for males across Indonesia increased from 62·5 years (95% uncertainty interval 61·3-63·7) to 69·4 years (67·2-71·6) between 1990 and 2019, a positive change of 6·9 years. For females during the same period, life expectancy increased from 65·7 years (64·5-66·8) to 73·5 years (71·6-75·6), an increase of 7·8 years. There were large disparities in health outcomes among provinces. In 2019, Bali had the highest life expectancy at birth for males (74·4 years, 70·90-77·9) and North Kalimantan had the highest life expectancy at birth for females (77·7 years, 74·7-81·2), whereas Papua had the lowest life expectancy at birth for males (64·5 years, 60·9-68·2) and North Maluku had the lowest life expectancy at birth for females (64·0 years, 60·7-67·3). The difference in life expectancy for males between the highest-ranked and lowest-ranked provinces was 9·9 years and the difference in life expectacy for females between the highest-ranked and lowest-ranked provinces was 13·7 years. Age-standardised death, YLL, and YLD rates also varied widely among the provinces in 2019. High systolic blood pressure, tobacco, dietary risks, high fasting plasma glucose, and high BMI were the five leading risks contributing to health loss measured as DALYs in 2019.Our findings highlight that Indonesia faces a double burden of communicable and non-communicable diseases that varies across provinces. From 1990 to 2019, Indonesia witnessed a decline in the infectious disease burden, although communicable diseases such as tuberculosis, diarrhoeal diseases, and lower respiratory infections have remained a main source of DALYs in Indonesia. During that same period, however, all-ages death and disability rates from non-communicable diseases and exposure to their risk factors accounted for larger shares of health loss. The differences in health outcomes between the highest-performing and lowest-performing provinces have also widened since 1990. Our findings support a comprehensive process to revisit current health policies, examine the root causes of variation in the burden of disease among provinces, and strengthen programmes and policies aimed at reducing disparities across the country.The BillMelinda Gates Foundation and the Government of Indonesia.For the Bahasa Indonesia translation of the abstract see Supplementary Materials section.

Pretreatment classification tools are used in prostate cancer to inform patient management. The effect of cribriform pattern 4 (CC) and intraductal carcinoma (IDC) on such nomograms is still underexplored. We analyzed the Cancer of Prostate Risk Assessment (CAPRA) and National Comprehensive Cancer Network (NCCN) risk scores in cases with and without CC/IDC to assess impact on biochemical recurrence (BCR) and metastases/death of prostate cancer (event free survival-EFS) after prostatectomy. A matched biopsy- prostatectomy cohort (2010-2017) was reviewed for CC/IDC. CAPRA and NCCN scores were calculated. CAPRA score 0-2 were deemed "low", 3-5 "intermediate" and 6-10 "high". NCCN scores 1-2 "very low/low", 3 "favorable intermediate", 4 "unfavorable intermediate", 5-6 "high/very high". Cases were stratified by presence of CC/IDC. BCR and EFS probabilities were estimated using the Kaplan-Meier method. Prognostic performance was evaluated using log-rank tests and Harrell's concordance index. 612 patients with mean age 63.1 years were included with mean follow up of 5.3 (range 0-10.8) years. CC/IDC was noted in 159/612 (26%) biopsies. There were 101 (17%) BCR and 36 (6%) events. CAPRA discriminated three distinct risk categories for BCR (p 0.001) while only high risk separated significantly for EFS (p 0.001). NCCN distinguished two prognostic groups for BCR (p 0.0001) and three for EFS (p 0.0001). Addition of CC/IDC to CAPRA impacted scores 3-5 for BCR and scores 3-5 and 6-10 for EFS and improved the overall concordance index (BCR: 0.66 vs. 0.71; EFS: 0.74 vs. 0.80). Addition of CC/IDC to NCCN impacted scores 4 and 5-6 and also improved the concordance index for BCR (0.62 vs. 0.68). Regarding EFS, NCCN scores 4 and 5-6 demonstrated markedly different outcomes with the addition of CC/IDC. The CAPRA nomogram allows better outcome stratification than NCCN. Addition of CC/IDC status particularly improves patient stratification for CAPRA scores 3-5, 6-10, and for NCCN scores 4 and 5-6.

Context: An Optimizing Performance through Intrinsic Motivation and Attention for Learning theory-based motor learning intervention delivering autonomy support and enhanced expectancies (EE) shows promise for reducing cognitive-motor dual-task costs, or the relative difference in primary task performance when completed with and without a secondary cognitive task, that facilitate adaptive injury-resistant movement response. The current pilot study sought to determine the effectiveness of an autonomy support versus an EE-enhanced virtual reality motor learning intervention to reduce dual-task costs during single-leg balance. Design: Within-subjects 3 × 3 trial. Methods: Twenty-one male and 24 female participants, between the ages of 18 and 30 years, with no history of concussion, vertigo, lower-extremity surgery, or lower-extremity injuries the previous 6 months, were recruited for training sessions on consecutive days. Training consisted of 5 × 8 single-leg squats on each leg, during which all participants mimicked an avatar through virtual reality goggles. The autonomy support group chose an avatar color, and the EE group received positive kinematic biofeedback. Baseline, immediate, and delayed retention testing consisted of single-leg balancing under single- and dual-task conditions. Mixed-model analysis of variances compared dual-task costs for center of pressure velocity and SD between groups on each limb. Results: On the right side, dual-task costs for anterior–posterior center of pressure mean and SD were reduced in the EE group (mean Δ = −51.40, Cohen d = 0.80 and SD Δ = −66.00%, Cohen d = 0.88) compared with the control group (mean Δ = −22.09, Cohen d = 0.33 and SD Δ = −36.10%, Cohen d = 0.68) from baseline to immediate retention. Conclusions: These findings indicate that EE strategies that can be easily implemented in a clinic or sport setting may be superior to task-irrelevant AS approaches for influencing injury-resistant movement adaptations.

Seizures are the most common sign of neurologic dysfunction, reflecting a wide variety of central nervous system disorders.A retrospective cross-sectional study of neonates with a clinical diagnosis of seizures was conducted in order to verify relationships between clinical aspects and EEG findings. Patients were divided into 3 groups according to the EEG recording available as: 1) with confirmatory ictal EEG; 2) with altered but non-ictal EEG; and 3) without any EEG recording. Variables related to pregnancy and birth history, neonatal complications, and seizure semiology (by video or clinical description) were compared to EEG findings.97 neonates were included (39.1% preterm, 54.6% male), 71 with available EEG data (56.3% with ictal EEG). The group without EEG presented clinical characteristics significantly different from the others such as extreme prematurity, low birth weight, and higher neonatal mortality (P = 0.002, 0.001, and 0.003, respectively). The most common etiology was hypoxic-ischemic encephalopathy (HIE) (46.4%) followed by vascular disorders, which predominated in extremely preterm neonates (P = 0.006). Sequential seizure was the most common type (44.6%) and was more frequently identified in term neonates (46%). In 51.2% of the ictal recordings the main finding was electrographic seizure without clinical manifestation. Discharge using antiseizure medication was higher among those with ictal or altered non-ictal EEG (P0.001).HIE is still a frequently etiology for neonatal seizures. Even if the patients in the sample were not under continuous EEG, the substantial proportion of electrographic seizures without clinical manifestations detected suggests the importance of continuous EEG monitoring in neonates at increased risk of seizures.

Is there any imbalance in the sex ratio at the blastocyst stage of human embryos? And what is the sex ratio in euploid, transferred, implanted blastocysts and at birth?Embryos from 646 women undergoing 921 preimplantation genetic testing for aneuploidy (PGT-A) cycles from September 2017 to February 2020 were included. Data from the chromosomal constitution of 2637 biopsied blastocysts were retrospectively analysed. Trophectoderm samples were analysed by next-generation sequencing. Embryos were categorized as euploid, mosaic or aneuploid. A total of 548 blastocysts diagnosed as euploid were warmed and transferred in a subsequent single-embryo transfer cycle.The blastocyst sex ratio was skewed in favour of male sex with 53.1% (1401/2637) of blastocysts diagnosed as male and 46.9% (1236/2637) as female (sex ratio 1.13, 95% confidence interval [CI] 1.05-1.22). Following biopsy and PGT-A, 41.2% (1086/2637) of blastocysts were classified as euploid, 7.7% (202/2637) as mosaic and 51.2% (1349/2637) as aneuploid. More chromosome euploidy was observed among female than male blastocysts (adjusted odds ratio 1.29, 95% CI 1.08-1.55) after adjusting for female age, male age and gonadotrophin dose. Euploid blastocysts were comparable between the sexes (sex ratio 0.99, 95% CI 0.88-1.11). No significant differences were observed between the sexes in implantation (sex ratio 0.86, 95% CI 0.68-1.08), miscarriage (sex ratio 1, 95% CI 0.51-1.97) or live birth rate (sex ratio 0.85, 95% CI 0.66-1.08).More male than female embryos develop to the blastocyst stage. Male blastocysts exhibit a higher aneuploidy rate. The capacity to implant and lead to a live birth is similar between the sexes.

Deciding which patients would benefit from intestinal transplantation (IT) remains an ethical/clinical dilemma. New criteria* were proposed in 2015: ≥2 intensive care unit (ICU) admissions, loss of ≥3 central venous catheter (CVC) sites, and persistently elevated conjugated bilirubin (CB ≥ 75 μmol/L) despite 6 weeks of lipid modification strategies. We performed a retrospective, international, multicenter validation study of 443 children (61% male, median gestational age 34 weeks [IQR 29-37]), diagnosed with IF between 2010 and 2015. Primary outcome measure was death or IT. Sensitivity, specificity, NPV, PPV, and probability of death/transplant (OR, 95% confidence intervals) were calculated for each criterion. Median age at IF diagnosis was 0.1 years (IQR 0.03-0.14) with median follow-up of 3.8 years (IQR 2.3-5.3). Forty of 443 (9%) patients died, 53 of 443 (12%) were transplanted; 11 died posttransplant. The validated criteria had a high predictive value of death/IT; ≥2 ICU admissions (p .0001, OR 10.2, 95% CI 4.0-25.6), persistent CB ≥ 75 μmol/L (p .0001, OR 8.2, 95% CI 4.8-13.9). and loss of ≥3 CVC sites (p = .0003, OR 5.7, 95% CI 2.2-14.7). This large, multicenter, international study in a contemporary cohort confirms the validity of the Toronto criteria. These validated criteria should guide listing decisions in pediatric IT.

Myxomas are rare tumors in neonates and tend to have a different presentation compared to adults. We present an infant with a left atrial myxoma presenting with episodic tachycardia who underwent successful surgical excision. In addition, we performed a review of the literature, identifying 17 cases of neonatal myxomas. Unlike adults, neonatal myxomas are more common in males and occur more often on the right side of the heart. Constitutional symptoms such as fever or embolism are rare among neonates. Most patients have favorable outcomes following surgical excision, refuting earlier claims that neonatal myxomas are associated with poor outcomes.

Lung segmentation using computed tomography (CT) images is important for diagnosing various lung diseases. Currently, no lung segmentation method has been developed for assessing the CT images of preschool children, which may differ from those of adults due to (1) presence of artifacts caused by the shaking of children, (2) loss of a localized lung area due to a failure to hold their breath, and (3) a smaller CT chest area, compared with adults. To solve these unique problems, this study developed an automatic lung segmentation method by combining traditional imaging methods with ResUnet using the CT images of 60 children, aged 0-6 years. First, the CT images were cropped and zoomed through ecological operations to concentrate the segmentation task on the chest area. Then, a ResUnet model was used to improve the loss for lung segmentation, and case-based connected domain operations were performed to filter the segmentation results and improve segmentation accuracy. The proposed method demonstrated promising segmentation results on a test set of 12 cases, with average accuracy, Dice, precision, and recall of 0.9479, 0.9678, 0.9711, and 0.9715, respectively, which achieved the best performance relative to the other six models. This study shows that the proposed method can achieve good segmentation results in CT of preschool children, laying a good foundation for the diagnosis of children’s lung diseases.

Safe intubation of newborns remains a challenge. This investigates the upper airway anatomy of (pre-)term infants was investigated to improve airway management and the development of airway devices. Angles and diameters of both oral and nasal intubation pathways of 22 cadavers of premature and term stillborn infants were measured, relative to their gestational age (GA) and tested for statistical significance. The systematic influence of sex on the distribution of values was examined. Cast models of the oral and nasal intubation pathway were (produced using a silicone dental impression material) 3D-scanned. No significant correlation with GA was seen in the angles studied. However, four distances around the hard and soft palate did show statistically significant positive correlations with GA. Regarding differences between the sexes, only the angle between the entrance of the trachea and the esophagus was greater for male cadavers. The angles of the ventilation pathway of (pre-)term infants do not depend systematically on GA. Anatomically, laryngeal masks might therefore also be well-suited ventilators for preterm infants. Alterations in the size but not the shape of laryngeal masks for small preterm infants is recommended. The data obtained may thus be used as a basis for the development of airway devices and airway simulators for medical education and clinical training.

This study aims to assess the natural history of congenital posteromedial bowing of the tibia (CPMBT) deformity during growth and to evaluate the outcomes of lengthening by an Ilizarov frame in CPMBT patients with limb length discrepancy (LLD).Between January 2000 and December 2019, a total of 22 patients (12 males, 10 females; mean age: 10.5±4.4 years; range, 6 to 19 years) with the diagnosis of CPMBT and followed closely from birth until skeletal maturity were retrospectively analyzed. The radiographic evaluation included the anteroposterior and lateral interphyseal angle and full leg standing radiographs. Limb lengthening by an Ilizarov frame was performed for an estimated LLD over 40 mm.The age of the patients ranged from six days to 10 months at the time of presentation, while the mean age at the final follow-up was 10.5±4.4 years. Posterior medial bowing was satisfactorily remodeled in 13 (59%) patients those were not operated either for deformity or LLD. The mean LLD was 21±4.1 mm in 13 nonoperated CPMBT patients. Nine of 22 (41%) patients underwent lengthening for LLD. Five of the nine CPMBT patients were operated under the age of 10 years, while four were operated over the age of 10 years.According to the results of the current study, CPMBT was satisfactorily remodeled in more than half of the patients, and the majority of patients did not undergo surgery for angular deformity and LLD within 10 years of their lives. Based on these findings, although most of the patients' deformities remodeled, it should be kept in mind that some may require lengthening surgery.

The Central Brain Tumor Registry of the United States (CBTRUS), in collaboration with the Centers for Disease Control and Prevention and the National Cancer Institute, is the largest population-based registry focused exclusively on primary brain and other central nervous system (CNS) tumors in the United States (US) and represents the entire US population. This report contains the most up-to-date population-based data on primary brain tumors available and supersedes all previous reports in terms of completeness and accuracy. All rates are age-adjusted using the 2000 US standard population and presented per 100,000 population. The average annual age-adjusted incidence rate (AAAIR) of all malignant and non-malignant brain and other CNS tumors was 24.71 per 100,000 population (malignant AAAIR=7.02 and non-malignant AAAIR=17.69). This overall rate was higher in females compared to males (27.62 versus 21.60 per 100,000) and non-Hispanic persons compared to Hispanic persons (25.09 versus 22.95 per 100,000). The most commonly occurring malignant brain and other CNS histopathology was glioblastoma (14.2% of all tumors and 50.1% of all malignant tumors), and the most common non-malignant histopathology was meningioma (39.7% of all tumors and 55.4% of all non-malignant tumors). Glioblastoma was more common in males, and meningiomas were more common in females. In children and adolescents (ages 0-19 years), the incidence rate of all primary brain and other CNS tumors was 6.20 per 100,000 population. An estimated 93,470 new cases of malignant and non-malignant brain and other CNS tumors are expected to be diagnosed in the US population in 2022 (26,670 malignant and 66,806 non-malignant). There were 84,264 deaths attributed to malignant brain and other CNS tumors between 2015 and 2019. This represents an average annual mortality rate of 4.41 per 100,000 population and an average of 16,853 deaths per year. The five-year relative survival rate following diagnosis of a malignant brain and other CNS tumor was 35.7%, while for non-malignant brain and other CNS tumors the five-year relative survival rate was 91.8%.

Aim and methods: Artificial neural networks were used to unravel connections among blood gene methylation levels, sex, maternal risk factors and symptom severity evaluated using the Autism Diagnostic Observation Schedule 2 (ADOS-2) score in 58 children with autism spectrum disorder (ASD). Results: Methylation levels of MECP2, HTR1A and OXTR genes were connected to females, and those of EN2, BCL2 and RELN genes to males. High gestational weight gain, lack of folic acid supplements, advanced maternal age, preterm birth, low birthweight and living in rural context were the best predictors of a high ADOS-2 score. Conclusion: Artificial neural networks revealed links among ASD maternal risk factors, symptom severity, gene methylation levels and sex differences in methylation that warrant further investigation in ASD.

Understanding and communicating the risk of pregnancy complications post-living kidney donation is imperative as the majority of living kidney donors (LKD) are women of childbearing age. We aimed to identify all original research articles examining complications in post-donation pregnancies and compared the quality and consistency of related guidelines. We searched Embase, MEDLINE, PubMed, society webpages, and guideline registries for English-language publications published up until December 18, 2020. Ninety-three articles were screened from which 16 studies were identified, with a total of 1399 post-donation pregnancies. The outcome of interest, post-donation pregnancy complications, was not calculable, and only a narrative synthesis of the evidence was possible. The absolute risk of pre-eclampsia increased from similar to 1%-3% pre-donation (lower than the general population) to similar to 4%-10% post-donation (comparable to the general population). The risks of adverse fetal and neonatal outcomes were no different between post-donation and pre-donation pregnancies. Guidelines and consensus statements were consistent in stating the need to inform LKDs of their post-donation pregnancy risk, however, the depth and scope of this guidance were variable. While the absolute risk of pregnancy complications remains low post-donation, a concerted effort is required to better identify and individualize risk in these women, such that consent to donation is truly informed.

Grief after infant death is a common experience of bereaved parents often seen in the neonatal intensive care unit (NICU). The NICU staff tend to focus more on the mother's support, and fathers are often not treated equally as mothers. This study aimed to investigate the circumstance of caring for parents facing infant death in NICUs.Twenty-eight face-to-face in-depth interviews were conducted between March 2018 and April 2019 in the northwest of Iran. Participants were selected via purposive sampling. An inductive thematic approach was used for data analysis.Three main themes and 7 subthemes were extracted. The main themes were: "the father-the missing piece of the puzzle in the mourning process," "restricted presence of fathers due to religious and traditional beliefs," and "the father-the patience stone."Due to cultural-religious backgrounds, traditional beliefs, structural problems, and organizational restrictions, fathers in NICUs do not receive adequate support, particularly when faced with their infant's death. Bereaved fathers need to receive more support and attention from healthcare providers. Therefore, there is a need for changing the care providers' attitudes regarding the role of fathers and the quality of support that fathers should receive in the Muslim populations.

Few reports have investigated medication-related osteonecrosis of the jaws (MRONJ) in the pediatric population. The study purpose was to measure the frequency of MRONJ in pediatric patients receiving antiresorptive medications at our institution.This retrospective case series was granted an exemption by the University of Texas Southwestern Medical Center Institutional Review Board. The primary outcome variable was the presence or absence of MRONJ. Other variables of interest included 1) age at first dose of antiresorptive; 2) sex; 3) antiresorptive medication received; 4) reason for antiresorptive; 5) dental records available; 6) dental extractions that occurred after the start of antiresorptive; 7) exposure to immunosuppressants/chemotherapy; 8) time interval from the last dose of antiresorptive to dental extractions; and 9) longest follow-up after starting antiresorptive. Frequencies and proportions were calculated for categorical data. Medians, means, and standard deviations were calculated for continuous data.The study sample was composed of 122 subjects. We observed 0 cases of MRONJ during the study interval. At the start of antiresorptive treatment, the average age was 8.18 years (range 0.02-17; standard deviation (SD) 5.15). There were 67 males (55%) and 55 females (45%). The reason for antiresorptive treatment was osteogenesis imperfecta in 36 patients, malignancy in 6 patients, and other in 80 patients. Thirty patients received pamidronate, 72 received zoledronate, 17 received a combination, and 3 received only denosumab. A total of 16 patients had exposure to immunosuppressants and/or chemotherapy. The average follow-up time was 4.89 years (median 4 years). Twenty-six patients underwent dental extractions of 74 teeth following antiresorptive treatment.While there were no reported cases of MRONJ in the present study, it is advisable to monitor pediatric patients who have received antiresorptive treatment closely. When possible, appropriate dental treatment should be completed prior to starting antiresorptive therapy. In the absence of reported MRONJ cases, dental extractions should not be withheld because of previous antiresorptive exposure and antiresorptive medication dosing need not be altered in the pediatric population.
