RESUMO
PURPOSE: The coronavirus disease 2019 (COVID-19) pandemic has a severe impact on the general population. During the pandemic, children may develop emotional and psychological symptoms, including increased worries about health and illness, known as health anxiety symptoms (HASs). We aimed to explore HAS in 7-9-year-old children from the Danish Odense Child Cohort (OCC) during the first COVID-19 lockdown period in Denmark, and to examine associations with potential risk factors. MATERIAL AND METHODS: OCC is a cohort of children born between 2010 and 2012, which originally recruited 2874 of 6707 pregnancies (43%). Among the current OCC population of 2430 singleton children, 994 participated in this study (response rate 40%). Children and their parents filled out questionnaires about child HAS, family exposure to COVID-19 infection and parental HAS. Adjusted odds ratios (aORs) were calculated between high score child HAS (≥90th percentile) and covariates by use of logistic regression. RESULTS: Most children (n = 686, 69%) reported few worries about their health. Children reporting high score HAS also had higher levels of internalizing symptoms at age 5; aOR 2.15 (1.20;3.85), p = .010, and higher levels of maternal and paternal HAS; aOR 2.40 (1.44;3.97), p = .001, and 2.00 (1.10;3.65), p = .023, whereas no association with child sex or familial exposure to COVID-19 was detected (n = 65, 6.5%). CONCLUSIONS: High score child HAS during the first lockdown period of the COVID-19 pandemic was not associated with family exposure to COVID-19 infection, but to being a more anxious child a priori and to HAS in parents.

BACKGROUND: Lower thyroid function outside pregnancy is associated with an increased risk of type 2 diabetes mellitus. The relationship between thyroid function in early pregnancy and glucose status in 3rd trimester has not been investigated. AIMS: To study the association between 1st trimester thyroid function and 3rd trimester glucose status. DESIGN: In the prospective study Odense Child Cohort (OCC), 1,041 women had 1st trimester blood samples analysed for thyroid-stimulating hormone (TSH), free T4 (FT4), thyroid peroxidase antibody and HbA1c. Third trimester (week 28) fasting blood samples included plasma glucose, insulin and HbA1c. Oral glucose tolerance test (OGTT, 75 g glucose) was performed in 509 women. First trimester FT4 was dichotomized >vs. ≤ the 25th percentile (25p = 12.9 pmol/L). Homeostatic model assessment-insulin resistance (HOMA)-IR and HOMA-ß were calculated. RESULTS: Women with FT4 ≤25p had significantly higher HbA1c in 1st and 3rd trimesters and higher 3rd trimester fasting glucose, insulin, HOMA-IR and HOMA-ß compared to women with FT4 >25p. In multiple regression analyses, FT4 was an independent negative predictor of 3rd trimester HbA1c. FT4 levels in 3rd and 4th quartiles (high-normal FT4 levels) showed closest inverse associations with HbA1c (p-trend <.001). TSH was not associated with 3rd trimester HbA1c. CONCLUSION: Women with lower levels of FT4 in early pregnancy had higher HbA1c in 3rd trimester and FT4 was an independent negative predictor of 3rd trimester HbA1c.

Vitamin D supplementation in infancy is recommended to prevent rickets. At the population level, its effects on bone mineralisation are largely unknown. We aimed to explore whether adherence to national vitamin D supplementation guidelines (10 µg/d up to the age of 2 years), supplementation at the ages of 5 and 7 years, and serum 25-hydroxyvitamin D (s-25(OH)D) at various time points associated with bone mineral density (BMD) at the age of 7 years in the Odense Child Cohort, Denmark (n 1194). High adherence was defined as supplementation with 10 µg of vitamin D 6-7 times per week during ≥80 % of the observation time. s-25(OH)D was analysed using LC-MS/MS. Total-body-less-head (TBLH) BMD was measured by dual-energy X-ray absorptiometry. At the median age of 18·1 months, 53·9 % (n 475/881) reported high adherence. The median s-25(OH)D was 64·7, 78·8, 46·0 and 71·8 nmol/l in early pregnancy, late pregnancy, cord blood and at 5 years, respectively. The mean TBLH BMD at the median age of 7·1 years was 0·613 (SD 0·049) g/cm2 (z-score +0·363 (SD 0·824)). In adjusted analyses, vitamin D supplementation up to 18 months, and at 5 and 7 years, was not associated with TBLH BMD. Similarly, no robust associations were found between TBLH BMD and s-25(OH)D at any time point. No associations were found for TBLH bone mineral concentration or bone area. In this population with relatively high s-25(OH)D concentrations, no consistent associations were found between adherence to vitamin D supplementation recommendations or vitamin D status in pregnancy or childhood, and bone mineralisation at the age of 7 years.

The most common genetic cause of neonatal diabetes and hyperinsulinism is pathogenic variants in ABCC8 and KCNJ11. These genes encode the subunits of the ß-cell ATP-sensitive potassium channel, a key component of the glucose-stimulated insulin secretion pathway. Mutations in the two genes cause dysregulated insulin secretion; inactivating mutations cause an oversecretion of insulin, leading to congenital hyperinsulinism, whereas activating mutations cause the opposing phenotype, diabetes. This review focuses on variants identified in ABCC8 and KCNJ11, the phenotypic spectrum and the treatment implications for individuals with pathogenic variants.

Monogenic diabetes is a rare type of diabetes resulting from mutations in a single gene. To date, most cases remain genetically unexplained, posing a challenge for accurate diabetes treatment, which leads to on a molecular diagnosis. Therefore, a trio exome scan was performed in a lean, nonsyndromic Caucasian girl with diabetes onset at 2½ years who was negative for autoantibodies. The lean father had diabetes from age 11 years. A novel heterozygous mutation in EDEM2, c.1271G > A; p.Arg424His, was found in the proband and father. Downregulation of Edem2 in rat RIN-m ß-cells resulted in a decrease in insulin genes Ins1 to 67.9% (p = 0.006) and Ins2 to 16.8% (p < 0.001) and reduced insulin secretion by 60.4% (p = 0.0003). Real-time PCR revealed a major disruption of endocrine pancreas-specific genes, including Glut2 and Pxd1, with mRNA suppression to 54% (p < 0.001) and 85.7% (p = 0.01), respectively. No other expression changes related to stress or apoptotic genes were observed. Extended clinical follow-up involving ten family members showed that two healthy individuals carried the same mutation with no sign of diabetes in the clinical screen except for a slight increase in IA-2 antibody in one of them, suggesting incomplete penetrance. In conclusion, we describe EDEM2 as a likely/potential novel diabetes gene, in which inhibition in vitro reduces the expression of ß-cell genes involved in the glucose-stimulated insulin secretion (GSIS) pathway, leading to an overall suppression of insulin secretion but not apoptosis.

The long-term consequences of transient neonatal hypoglycemia are sparsely studied. We performed a follow-up of a cohort of neonates with blood glucose recordings < 1.7 mmol/L (< 30 mg/dL), treated with > 2.5 mmol/L (> 45 mg/dL), compared with healthy siblings. Exclusion criteria were gestational age < 35 weeks, severe asphyxia, head injury, and other cerebral diseases. In 71 children with neonatal hypoglycemia and 32 control siblings, Wechsler IV cognitive test, Movement ABC-2 test, and Child Behavior Checklist were performed at mean age 7.75 and 9.17 years, respectively. No significant changes were detected for cognitive function by using Wechsler IV or for behavior by using Child Behavior Checklist. In univariate analysis, the hypoglycemia group had lower age-adjusted fine motor scores by using the Movement ABC-2 test compared with control siblings, 42.6 ± 31.2 vs. 57.2 ± 30.8 percentile (p = 0.03). In the sibling-paired analysis, the decrease in total motor score was highly significant, p = 0.009, driven by a decrease in fine motor score, p = 0.008. In the hypoglycemia group, adjusted analysis showed a lower fine motor function for boys, ß = - 16.4, p = 0.048.Conclusion: Neonatal hypoglycemia treated with > 2.5 mmol/L was associated with lower fine motor scores within the normal range, particularly in boys. No associations with cognitive function or behavior were detected. What is Known: ⢠Transient neonatal hypoglycemia is associated with acute neurologic dysfunction and long-term neurodevelopment impairment in 18 months of age. What is New: ⢠Neonatal hypoglycemia treated with > 2.5 mmol/L is associated with lower fine motor function within the normal range, particularly in boys, but not to changes in cognitive function or behavior.

RESUMO
PURPOSE: Focal congenital hyperinsulinism (CHI) is curable by surgery, which is why identification of the focal lesion is crucial. We aimed to determine the use of 18F-fluoro-dihydroxyphenylalanine (18F-DOPA) PET/CT vs. 68Ga-1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic-acid-1-Nal3-octreotide (68Ga-DOTANOC) PET/CT as diagnostic tools in focal CHI. METHODS: PET/CT scans of children with CHI admitted to Odense University Hospital between August 2005 and June 2016 were retrospectively evaluated visually and by their maximal standardized uptake values (SUVmax) by two independent examiners, blinded for clinical, surgical and pathological data. Pancreatic histology was used as the gold standard. For patients without surgery, the genetic profile served as the gold standard. RESULTS: Fifty-five CHI patients were examined by PET/CT (18F-DOPA n = 53, 68Ga-DOTANOC n = 18). Surgery was performed in 34 patients, no surgery in 21 patients. Fifty-one patients had a classifiable outcome, either by histology (n = 33, 22 focal lesions, 11 non-focal) or by genetics (n = 18, all non-focal). The predictive performance of 18F-DOPA PET/CT to identify focal CHI was identical by visual- and cut-off-based evaluation: sensitivity (95% CI) of 1 (0.85-1); specificity of 0.96 (0.82-0.99). The optimal 18F-DOPA PET SUVmax ratio cut-off was 1.44 and the optimal 68Ga-DOTANOC PET SUVmax cut-off was 6.77 g/ml. The area under the receiver operating curve was 0.98 (0.93-1) for 18F-DOPA PET vs. 0.71 (0.43-0.95) for 68Ga-DOTANOC PET (p < 0.03). In patients subjected to surgery, localization of the focal lesion was correct in 91%, and 100%, by 18F-DOPA PET/CT and 68Ga-DOTANOC PET/CT, respectively. CONCLUSION: 18F-DOPA PET/CT was excellent in predicting focal CHI and superior compared to 68Ga-DOTANOC PET/CT. Further use of 68GA-DOTANOC PET/CT in predicting focal CHI is discouraged.

Skull changes are poorly described in vitamin D insufficiency [serum 25-hydroxyvitamin D (s-25(OH)D) 25-50 nmol/L]. We aimed to investigate factors associated with cranial anthropometrics in infants, especially s-25(OH)D. In infants 2.5-6 months old from the Odense Child Cohort, associations between cord and pregnancy s-25(OH)D and anterior fontanel area (n = 765), head circumference (HC, n = 1776) and head shape (n = 1527) were investigated along with other factors. Age was corrected for preterm birth. The mean (SD) s-25(OH)D in early pregnancy was 65.97 (21.33) nmol/L; late pregnancy 78.61 (27.18) nmol/L; and cord 47.1 (21.7) nmol/L. At median (IQR) age 3.7 (2.5-5.9) months, the fontanel area was 225 (0-1690) mm2, and mean (SD) HC was 41.5 (1.5) cm. Asymmetric/flat head shape was present in 846 infants (55.3%). No associations were found between cord, early or late pregnancy s-25(OH)D and any cranial measure by univariate or adjusted analysis. Among significant, independent associations in multivariate analysis, fontanel area was associated inversely with gestational age (GA); HC was associated directly with GA, maternal pre-pregnancy overweight and caesarean section and inversely with smoking; and asymmetrical head shape showed a novel association with male sex: adjusted OR = 1.54 (95% CI 1.25; 1.89), p < 0.001. Other associations with asymmetrical head shape included parity 3+, gestational age and maternal age 30+ years (all protective). In conclusion, neither pregnancy nor cord s-25(OH)D was associated with fontanel size, HC or asymmetrical head shape despite a high prevalence of cord s-25(OH)D < 50 nmol/L. Lower GA was associated with larger fontanel size, lower HC and asymmetrical head shape, and boys more frequently had asymmetrical head shape, probably due to heavier heads.

AIM: Previous studies have found high rates of stunted linear growth in Greenlandic children. We measured growth patterns in Greenland and compared them with international growth charts. METHODS: The study cohort comprised 279 healthy children aged 6-10 years in 2012. They participated in two pregnancy and birth cohorts in Greenland and longitudinal growth data as birth was extracted from their medical records. Growth reference ranges were estimated with the lambda-mu-sigma (LMS) method and compared with growth charts from Denmark and the World Health Organization (WHO). RESULTS: The children's mean length, weight and head circumference were significantly larger than the WHO growth charts (p < 0.001). We found that 21-28% of the children aged zero to one years exceeded the WHO growth chart for length by more than two standard deviations. For weight and head circumference, 9-16% of the children aged 0-10 years and 9-11% of the children from zero to two years exceeded the WHO charts by more than two standard deviations. The Danish references were exceeded to a lesser degree. CONCLUSION: This study showed that the growth of Greenlandic children up to 10 years was no longer stunted. Major determining factors suggested are genetic admixture, maternal overweight, changes in nutrition and improved health.

The aim was to describe medication errors (MEs) in hospitalized children reported to the national mandatory reporting and learning system, the Danish Patient Safety Database (DPSD). MEs were extracted from DPSD from the 5-year period of 2010-2014. We included reports from public hospitals on patients aged 0-17 years and categorized by reporters as medication-related. Reports from psychiatric wards and outpatient clinics were excluded. A ME was defined as any medication-related error occurring in the medication process whether harmful or not. MEs were categorized as harmful if they resulted in actual harm or interventions to prevent harm. MEs were further categorized according to occurrence in the medication process, type of error, and the medicines involved. A total of 2071 MEs including 487 harmful MEs were identified. Most MEs occurred during prescribing (40.8%), followed by dispensing (38.7%). Harmful MEs occurred mainly during dispensing (40.3%). Dosing errors were the most reported type of error, 47.7% of all MEs and 45.4% of harmful MEs. Antibiotics and analgesics were the most frequently reported medication classes. Common medicines associated with MEs included morphine, paracetamol, and gentamicin. MEs caused no harm (74.9%), mild (11.7%), moderate (10.5%), or severe harm (1.3%), but none were lethal. CONCLUSION: MEs in hospitalized children occur in all medication processes and mainly involve dosing errors. Strategies should be developed to prevent MEs as these still threaten medication safety in pediatric inpatients. What is known: ⢠Hospitalized children are more likely to experience medication errors than adults. ⢠Voluntary national and local reporting and learning systems have previously been used to describe the nature and types of medication errors. What is new: ⢠Medication errors in hospitalized children occur in all steps of the medication process, most frequently involving dosing errors and most commonly involving morphine, paracetamol, and gentamicin. ⢠Of the medication errors, 1.3% cause severe harm, but no fatal errors were reported.

Respiratory distress syndrome (RDS) and bronchopulmonary dysplasia (BPD) are major complications to preterm birth. Hypovitaminosis D is prevalent in pregnancy. We systematically reviewed the evidence of the impact of vitamin D on lung development, surfactant synthesis, RDS, and BPD searching PubMed, Embase, and Cochrane databases with the terms vitamin D AND (surfactant OR lung maturation OR lung development OR respiratory distress syndrome OR fetal lung OR prematurity OR bronchopulmonary dysplasia). Three human studies, ten animal studies, two laboratory studies, and one combined animal and laboratory study were included. Human evidence was sparse, allowing no conclusions. BPD was not associated with vitamin D receptor polymorphism in a fully adjusted analysis. Animal and laboratory studies showed substantial positive effects of vitamin D on the alveolar type II cell, fibroblast proliferation, surfactant synthesis, and alveolarization. These data support the hypothesis of hypovitaminosis D as a frequent, modifiable risk factor of RDS and BPD, which should be tested in randomized controlled trials on pregnant women, those with threatening preterm delivery, or in the preterm neonates. Future experimental and human studies should aim to identify optimal time windows, vitamin D doses, and cut-off levels for 25-hydroxyvitamin D in interventions against RDS, BPD, and later adverse respiratory outcomes.

BACKGROUND: The importance of the environment on the development of the fetus and infant throughout early life is increasingly recognised. To study such effects, biological samples and accurate data records are required. Based on multiple data collection from a healthy pregnant population, the Odense Childhood Cohort (OCC) study aims to provide new information about the environmental impact on child health by sequential follow-up to 18 years of age among children born between 2010 and 2012. METHODS: A total of 2874 of 6707 pregnancies (43%) were recruited between January 2010 and December 2012. Three hundred seventy-four have since left the study, leaving 2500 active families. The non-participants act as controls contributing data through local registries. Biological material, questionnaires, and registry data were compiled. Anthropometric data and other physical data were collected. RESULTS: Two thousand five hundred families actively participated in the study with 2549 children. Sixty-four per cent of the fathers and 60% and 58% of the mothers, respectively, donated a blood sample at 10 and 28 weeks of gestation. On average, 69% completed questionnaires, 78% of the children were regularly examined, and had a blood sample taken (46%). The participating pregnant women differed from the non-participants in several respects: age, body mass index, smoking, parity, education, and ethnicity. The infants were comparable with respect to gender and mode of delivery. CONCLUSIONS: The OCC provides material for in-depth analysis of environmental and genetic factors that are important for child health and disease. Registry data from non-participating women and infants are available which ensures a high degree of comparable data.

Hyperinsulinemic hypoglycemia (HH) of pancreatic origin includes congenital hyperinsulinism (CHI), insulinoma, insulinomatosis, and adult-onset non-insulinoma persistent hyperinsulinemic hypoglycemia syndrome (NI-PHHS). In this review, we describe the genotype-histotype-phenotype correlations in HH and their therapeutic implications. CHI can occur from birth or later on in life. Histologically, diffuse CHI shows diffuse beta cell hypertrophy with a few giant nuclei per islet of Langerhans, most frequently caused by loss-of-function mutations in ABCC8 or KCNJ11. Focal CHI is histologically characterized by focal adenomatous hyperplasia consisting of confluent hyperplastic islets, caused by a paternal ABCC8/KCNJ11 mutation combined with paternal uniparental disomy of 11p15. CHI in Beckwith-Wiedemann syndrome is caused by mosaic changes in the imprinting region 11p15.4-11p15.5, leading to segmental or diffuse overgrowth of endocrine tissue in the pancreas. Morphological mosaicism of pancreatic islets is characterized by occurence of hyperplastic (type 1) islets in one or a few lobules and small (type 2) islets in the entire pancreas. Other rare genetic causes of CHI show less characteristic or unspecific histology. HH with a predominant adult onset includes insulinomas, which are pancreatic insulin-producing endocrine neoplasms, in some cases with metastatic potential. Insulinomas occur sporadically or as part of multiple endocrine neoplasia type 1 due to MEN1 mutations. MAFA mutations may histologically lead to insulinomatosis with insulin-producing neuroendocrine microadenomas or neuroendocrine neoplasms. NI-PHHS is mainly seen in adults and shows slight histological changes in some patients, which have been defined as major and minor criteria. The genetic cause is unknown in most cases. The diagnosis of HH, as defined by genetic, histological, and phenotypic features, has important implications for patient management and outcome.

Introduction: Well-differentiated pancreatic neuroendocrine tumors (PNETs) can be non-functional or functional, e.g. insulinoma and glucagonoma. The majority of PNETs are sporadic, but PNETs also occur in hereditary syndromes, primarily multiple endocrine neoplasia type 1 (MEN1). The Knudson hypothesis stated a second, somatic hit in MEN1 as the cause of PNETs of MEN1 syndrome. In the recent years, reports on genetic somatic events in both sporadic and hereditary PNETs have emerged, providing a basis for a more detailed molecular understanding of the pathophysiology. In this systematic review and meta-analysis, we made a collation and statistical analysis of aggregated frequent genetic alterations and potential driver events in human grade G1/G2 PNETs. Methods: A systematic search was performed in concordance with the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) reporting guidelines of 2020. A search in Pubmed for published studies using whole exome, whole genome, or targeted gene panel (+400 genes) sequencing of human G1/G2 PNETs was conducted at the 25th of September 2023. Fourteen datasets from published studies were included with data on 221 patients and 225 G1/G2 PNETs, which were divided into sporadic tumors, and hereditary tumors with pre-disposing germline variants, and tumors with unknown germline status. Further, non-functioning and functioning PNETs were distinguished into two groups for pathway evaluation. The collated genetical analyses were conducted using the 'maftools' R-package. Results: Sporadic PNETs accounted 72.0% (162/225), hereditary PNETs 13.3% (30/225), unknown germline status 14.7% (33/225). The most frequently altered gene was MEN1, with somatic variants and copy number variations in overall 42% (95/225); hereditary PNETs (germline variations in MEN1, VHL, CHEK2, BRCA2, PTEN, CDKN1B, and/or MUTYH) 57% (16/30); sporadic PNETs 36% (58/162); unknown germline status 64% (21/33). The MEN1 point mutations/indels were distributed throughout MEN1. Overall, DAXX (16%, 37/225) and ATRX-variants (12%, 27/225) were also abundant with missense mutations clustered in mutational hotspots associated with histone binding, and translocase activity, respectively. DAXX mutations occurred more frequently in PNETs with MEN1 mutations, p<0.05. While functioning PNETs shared few variated genes, non-functioning PNETs had more recurrent variations in genes associated with the Phosphoinositide 3-kinase, Wnt, NOTCH, and Receptor Tyrosine Kinase-Ras signaling onco-pathways. Discussion: The somatic genetic alterations in G1/G2 PNETs are diverse, but with distinct differences between sporadic vs. hereditary, and functional vs. non-functional PNETs. Increased understanding of the genetic alterations may lead to identification of more drivers and driver hotspots in the tumorigenesis in well-differentiated PNETs, potentially giving a basis for the identification of new drug targets.

BACKGROUND: In rare diseases, limited access to services and rare disease experts may force families to act as medical advocates for their child; they can volunteer to support clinician-initiated research or initiate and lead research themselves. Ketotic Hypoglycemia International (KHI) is a new, global organization for families affected by idiopathic ketotic hypoglycemia (IKH) and is run solely by volunteers. Doing research together, families and international experts in a collaborative process such as at KHI, also referred to as patient and public involvement and engagement (PPIE) or extreme citizen science, is often praised for its positive effects on the research and the stakeholders involved. METHODS: We used auto-ethnographic narratives from parents and medical professionals in KHI to report on their experiences with co-produced health research. All co-authors wrote down their experiences in relation to three topics: time invested, work invested and power dynamics. RESULTS: Whilst the parents and health care professionals felt a new hope for (their) children with IKH, they also felt pressure to contribute time or to be flexible in how and when they dedicated time towards the organization. The power dynamics were characterised by a change in the relationship between the parents and medical experts; the parent being taught by the expert shifted to the expert learning from the lived experience of the parent. Both parents and medical experts struggled with maintaining boundaries and safeguarding their mental health. CONCLUSION: Our findings call for the need to secure and prioritize funding for patient organizations, to enable them to create the sustainable architecture required for meaningful PPIE within these organizations. The morals and often deeply personal reasons for engaging with voluntary work in health research, can lead to overstepping of boundaries. As a result of our research, we call for the development of ethics of care guidelines within collaborative health research.
When confronted with a rare disease it is often hard to access information and or medical experts for help. Parents of children affected by idiopathic ketotic hypoglycemia (IKH) have joined in a patient-led organisation to initiate and lead research that could give answers to their medical questions and worries. Medical experts have been invited to join the organisation as members of the Scientific Advisory Board (SAB). When people report on health research conducted in collaboration with patients and or members of the public, they mostly mention positive outcomes. At KHI, some people had left the organisation and we had to deal with some difficult situations; so, we wanted to document and understand these challenges. Nine members of KHI, parents and medical experts, wrote down their stories, using three topics to guide their narrative: time invested, work invested and power dynamics at KHI. Parents and medical experts felt a new hope for (their) children with IKH when working for KHI but they also felt pressured to work at all hours and at the cost of time with their families or their own health. The stories revealed that parents felt less important compared to medical experts, but also that the relationship between parents and experts changed from the parent being taught by the expert, to the expert starting to learn from the lived experience of the parent. To make these collaborations successful we plead for funding for patient-led organisation and ethical guidelines to safeguard volunteers (both medical and lay people).
RESUMO
Maternal dietary factors have been suggested as possible contributing influences for congenital anomalies (CAs). We aimed to assess the association between vitamin D supplementation or vitamin D status (s-25OHD) during pregnancy and CAs in the offspring. A comprehensive literature search was conducted in the three electronic databases: PubMed, Embase, and Cochrane Library. Included studies were critically appraised using appropriate tools (risk of bias 2, ROBINS-I). A protocol was registered in the International Prospective Register of Systematic Reviews (CRD42019127131). A meta-analysis of four randomised controlled trials (RCTs) including 3931 participants showed no effect of vitamin D supplementation on CAs, a relative risk of 0.76 (95% CI 0.45; 1.30), with moderate certainty in the effect estimates by GRADE assessment. Of the nine identified observational studies, six were excluded due to a critical risk of bias in accordance with ROBINS-I. Among the included observational studies, two studies found no association, whereas one case-control study identified an association between s-25OHD < 20 nmol/L and neural tube defects, with an adjusted odds ratio of 2.34 (95% CI: 1.07; 5.07). Interpretation of the results should be cautious given the low prevalence of CAs, RCTs with onset of supplementation after organogenesis, and low-quality observational studies.

CONTEXT: Congenital combined pituitary hormone deficiency (cCPHD) is the loss of ≥2 pituitary hormones caused by congenital factors. OBJECTIVE: We aimed to estimate the national incidence of cCPHD diagnosed before age 18 years and in subgroups. METHODS: Patients with cCPHD were identified in the Danish National Patient Registry and Danish hospital registries in the period 1996-2020. Hospital files were reviewed and incidences calculated using background population data. Incidence was the main outcome measure. RESULTS: We identified 128 patients with cCPHD; 88 (68.8%) were males. The median (range) age at diagnosis was 6.2 (0.01-19.0) years. The median (25th;75th percentile) number of hormone deficiencies at diagnosis was 3 (3; 4) at <1 year vs 2 (2; 2) at 1-17 years, P < .0001. Abnormal pituitary magnetic resonance imaging findings were seen in 70.3% (83/118). For those born in Denmark aged <18 years at diagnosis (n = 116/128) the estimated national incidence (95% CI) of cCPHD was 10.34 (7.79-13.72) per 100 000 births, with an annual incidence rate of 5.74 (4.33-7.62) per million. In subgroup analysis (diagnosis <1 vs 1-17 years), the incidence was highest in the 1-17 years subgroup, 7.97 (5.77-11.00) vs 1.98 (1.39-2.84) per 100 000 births, whereas the annual incidence rate was highest at <1 year, 19.8 (13.9-28.4) vs 4.69 (3.39-6.47) per million births. CONCLUSION: cCPHD had the highest incidence rate and the most hormone deficiencies in those diagnosed at <1 year. The incidence was highest in the 1-17 years age group, underscoring the need for multiple pituitary hormone investigations throughout childhood and adolescence in children with only 1 hormone deficiency.

BACKGROUND: Synthetic glucocorticoid exposure in late pregnancy may be associated with higher blood pressure in offspring. We hypothesized that endogenous cortisol in pregnancy relates to offspring blood pressure (OBP). OBJECTIVE: To investigate associations between maternal cortisol status in third trimester pregnancy and OBP. METHODS: We included 1317 mother-child pairs from Odense Child Cohort, an observational prospective cohort. Serum (s-) cortisol and 24-hour urine (u-) cortisol and cortisone were assessed in gestational week 28. Offspring systolic blood pressure and diastolic blood pressure were measured at age 3, 18 months, and 3 and 5 years. Associations between maternal cortisol and OBP were examined by mixed effects linear models. RESULTS: All significant associations between maternal cortisol and OBP were negative. In boys in pooled analyses, 1 nmol/L increase in maternal s-cortisol was associated with average decrease in systolic blood pressure (ß=-0.003 mmHg [95% CI, -0.005 to -0.0003]) and diastolic blood pressure (ß=-0.002 mmHg [95% CI, -0.004 to -0.0004]) after adjusting for confounders. At 3 months of age, higher maternal s-cortisol was significantly associated with lower systolic blood pressure (ß=-0.01 mmHg [95% CI, -0.01 to -0.004]) and diastolic blood pressure (ß=-0.010 mmHg [95% CI, -0.012 to -0.011]) in boys after adjusting for confounders, which remained significant after adjusting for potential intermediate factors. CONCLUSIONS: We found temporal sex dimorphic negative associations between maternal s-cortisol levels and OBP, with significant findings in boys. We conclude that physiological maternal cortisol is not a risk factor for higher blood pressure in offspring up to 5 years of age.

Neonatal lupus erythematosus (NLE) is a rare, passively acquired autoimmune disease, caused by maternal autoantibodies. Characteristic clinical features of NLE are transient rash and congenital heart block (CHB), but also hematological abnormalities and hepatobiliary dysfunction may occur. Complications to the transient dermatitis are rarely described. We describe two patients with NLE and cutaneous manifestations. Both patients had involvement of the sun-protected genital skin and soles. New manifestations of NLE were gastrointestinal bleeding in one patient despite normal coagulation parameters, but with mucosal telangiectatic lesions found on sigmoidoscopy. In addition, one patient developed painful atrophy after plantar dermatitis on follow-up with need of orthopedic footwear. CHB was not found. In conclusion, NLE may be complicated with sigmoidal telangiectasia with rectal bleeding and painful plantar atrophy.
