Article Synopsis
  • The study aimed to create new reference charts for measuring the length of the fetal corpus callosum (CC) during the third trimester, based on a large sample of healthy fetuses, and establish growth evaluation standards using CC length ratios.
  • Conducted from November 2021 to June 2022 at a specialized fetal ultrasound center, the research involved precise measurements of the CC in fetuses aged 17 to 36 weeks, excluding those with inaccurate gestational ages or high risk of brain abnormalities.
  • Results showed high measurement quality (92.8% accuracy) and established a formula for CC length based on gestational age, with consistent ECOFD/CC and HC/CC ratios, proposing them as additional markers for normal CC

MRC National Mouse Genetics Network, Congenital Anomalies Cluster, Harwell, OX11 0RD, UK.

Congenital heart defects (CHDs), the most common congenital anomalies, are considered to have a significant genetic component. However, despite considerable efforts to identify pathogenic genes in patients with CHDs, few gene variants have been proven as causal. The complexity of the genetic architecture underlying human CHDs likely contributes to this poor genetic discovery rate.

Light transmission aggregometry (LTA) is a method used to investigate platelet functions in platelet-rich plasma (PRP), notably when screening for platelet disorders. Various national guidelines and recommendations help in setting up the LTA test in specialized laboratories. However, due to the nature of the sample matrix and its subsequent specificities, more accurate positions are needed to achieve LTA accreditation according to the standard NF EN ISO 15 189.

Article Synopsis
  • - The study compares genotypes between pediatric cardiomyopathy (pCM) and adult-onset cardiomyopathy (aCM) to understand why pCM has earlier onset and differs in severity.
  • - Analysis of 253 pCM patients revealed a higher rate of genetic variants, particularly in restrictive pCM, and identified critical risk factors for adverse outcomes such as early diagnosis and presence of multiple variants.
  • - Genetic testing not only clarified the genetic basis for pCM but also enhanced genetic counseling for families, resulting in cases of prenatal diagnosis.

The main monogenic causes of pulmonary fibrosis in adults are mutations in telomere-related genes. These mutations may be associated with extrapulmonary signs (hepatic, haematological and dermatological) and typically present radiologically as usual interstitial pneumonia or unclassifiable fibrosis. In children, the monogenic causes of pulmonary fibrosis are dominated by mutations in surfactant-related genes.

We report on a 7-month-old boy (4.2 kg/60 cm) with severe immunodeficiency disorder and bacterial septicaemia who was referred for an infected atrial thrombus secondary to a jugular central line. The echocardiogram showed a teardrop-shaped thrombus with a wide base adherent to the interatrial wall and a flimsy tail moving freely in the right atrium.

Retinopathy of prematurity (ROP, ORPHA: 90050) is the main cause of visual impairment in preterm infants and the leading preventable cause of childhood blindness in high- and middle-income countries. However, severe stages of the disease remain rare. While screening recommendations for the disease are well-established in France, management of ROP requiring treatment is less standardized, especially since new therapeutic options have been approval on this indication.

Objectives: A new form of systemic juvenile idiopathic arthritis (SJIA) with associated lung disease (SJIA-LD) has recently been described. Multiple lines of treatment have failed to yield satisfactory results for this disorder. JAK inhibitors (JAKis) have recently been approved for the treatment of JIA, but clinical evidence of their efficacy in SJIA-LD is still weak.

Article Synopsis
  • IRAP is an enzyme found in various immune cells, and it helps regulate the body's immune response; its genetic variants are linked to survival rates in septic shock patients.
  • In a study modeling systemic inflammation from gram-negative sepsis using LPS, immune responses were compared between IRAP knockout and wildtype mice.
  • Results showed that IRAP deficiency led to increased activation and pro-inflammatory response in dendritic cells and macrophages, highlighting the enzyme's role in inflammation, which varies by time and sex.

We have previously developed seven fluorinated analogues of A-836339 as new PET tracers for cannabinoid type 2 receptor (CBR) imaging, among which ()--(3-(2-(2-[F]fluoroethoxy)ethyl)-4,5-dimethylthiazol-2(3)-ylidene)-2,2,3,3-tetramethylcyclopropane-1-carboxamide ([F]FC0324) displayed high affinity and selectivity for CBR in healthy rats. In the present study, we have further evaluated the imaging and metabolic properties of [F]FC0324 in a rat model of human CBR overexpression in the brain (AAV-CB) and in non-human primates (NHPs). Autoradiography with AAV-CB rat brain sections exhibited a signal of [F]FC0324 8-fold higher in the ipsilateral region than in the contralateral region.

Article Synopsis
  • PAX6-related congenital aniridia is a genetic eye condition leading to absent or underdeveloped iris and fovea, potentially causing ocular hypertension and glaucoma, though the exact causes are still not fully understood.* -
  • New imaging techniques have revealed possible reasons for glaucoma in these patients, including trabecular dysfunction and angle closure, but accurate diagnosis can be complicated by factors like corneal opacity and significant nystagmus.* -
  • Glaucoma treatment mainly involves medication, and any surgical options must be carefully assessed to weigh potential risks against benefits, considering the unique challenges posed by congenital aniridia.*

Article Synopsis
  • - Distal renal tubular acidosis (dRTA) is a condition where the kidneys can't properly excrete acids, leading to metabolic acidosis, low potassium levels, and high calcium in urine, often due to genetic defects in specific genes or acquired causes like autoimmune disorders or drugs.
  • - The complications of dRTA include kidney stones, damage to the kidneys, weakened bones, and stunted growth, making treatment essential for overall health.
  • - Recent developments include ADV7103, an investigational drug approved by the European Medicine Agency, which offers a new way to manage dRTA by helping to correct acid-base imbalances and improve adherence compared to traditional treatments.

Unlabelled: Systemic juvenile idiopathic arthritis (sJIA) and adult-onset Still's disease (AOSD) are considered the same disease, but a common approach for diagnosis and management is still missing.

Methods: In May 2022, EULAR and PReS endorsed a proposal for a joint task force (TF) to develop recommendations for the diagnosis and management of sJIA and AOSD. The TF agreed during a first meeting to address four topics: similarity between sJIA and AOSD, diagnostic biomarkers, therapeutic targets and strategies and complications including macrophage activation syndrome (MAS).

Electronic address:

Objectives: Patients with inherited metabolic disorders (IMDs) may require emergency hospital care to prevent life-threatening situations such as metabolic decompensation. To date, over one thousand different rare IMDs have been identified, which means that healthcare professionals (HCPs) initiating emergency treatment may not be familiar with these conditions. The objective of this initiative was to provide HCPs with practical guidance for the acute management of children and adults with IMDs who need emergency care, regardless of the underlying reason.

Article Synopsis
  • The human immune system continues to develop for several years after birth, affecting how young children respond to infections, such as SARS-CoV-2.
  • Researchers studied T cell responses in children and adults before, during, and after SARS-CoV-2 infection, revealing that younger children (under 5) had a weaker CD4 T cell response compared to older children and adults with mild disease.
  • Following infection, preschool-age children produced similar neutralizing antibodies to adults but had different T cell characteristics and fewer memory B cells, indicating a gradual maturation of their adaptive immune responses.

Article Synopsis
  • - Minimal change disease (MCD) and focal segmental glomerulosclerosis are common in children with idiopathic nephrotic syndrome, with MCD being highly responsive to steroids and generally not requiring a kidney biopsy at diagnosis.
  • - Kidney biopsies should be reserved for atypical symptoms, steroid resistance, or to investigate possible systemic diseases, as they are invasive and can cause complications.
  • - New non-invasive biomarkers are being developed to reduce the need for biopsies, and starting steroid treatment in teenagers with typical nephrotic syndrome is a sensible approach.
