A case series exploring the human milk polyclonal IgA1 response to repeated SARS-CoV-2 vaccinations by LC-MS based fab profiling.

Introduction: Upon vaccination against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) humans will start to produce antibodies targeting virus specific antigens that will end up in circulation. In lactating women such antibodies will also end up in breastmilk, primarily in the form of secretory immunoglobulin A1 (SIgA1), the most abundant immunoglobulin (Ig) in human milk. Here we set out to investigate the SIgA1 clonal repertoire response to repeated SARS-CoV-2 vaccination, using a LC-MS fragment antigen-binding (Fab) clonal profiling approach.

COVID-19 mRNA vaccination during pregnancy does not harm syncytiotrophoblast development.

Objectives: The safety of COVID-19 messenger RNA (mRNA) vaccination during pregnancy remains a topic of concern. Its effect on placenta development has been poorly studied, even though this is essential for healthy pregnancy outcomes. We investigated the effect of the maternal immune response to COVID-19 mRNA vaccination on the development of syncytiotrophoblast (STB), a functional cell layer of the placenta where the maternal-fetal exchange takes place.

Should non-invasive prenatal testing (NIPT) be used for fetal sex determination? Perspectives and experiences of healthcare professionals.

Non-invasive prenatal testing (NIPT) can not only accurately detect early in pregnancy the presence of chromosomal abnormalities but also fetal sex. However, whether fetal sex should be reported after performing NIPT is ethically contentious. In Belgium, NIPT is practically fully reimbursed and offered to all pregnant women as a first-tier screening.

Favorable culture conditions for spermatogonial propagation in human and non-human primate primary testicular cell cultures: a systematic review and meta-analysis.

Autologous transplantation of spermatogonial stem cells (SSCs) isolated from cryopreserved testicular biopsies obtained before oncological treatment could restore fertility in male childhood cancer survivors. There is a clear necessity for propagation of the limited SSCs from the testicular biopsy prior to transplantation due to limited numbers of spermatogonia in a cryopreserved testicular biopsy. Still, there is no consensus regarding their optimal culture method.

Diagnostic utility and reporting recommendations for clinical DNA methylation episignature testing in genetically undiagnosed rare diseases.

Purpose: This study aims to assess the diagnostic utility and provide reporting recommendations for clinical DNA methylation episignature testing based on the cohort of patients tested through the EpiSign Clinical Testing Network.

Methods: The EpiSign assay utilized unsupervised clustering techniques and a support vector machine-based classification algorithm to compare each patient's genome-wide DNA methylation profile with the EpiSign Knowledge Database, yielding the result that was reported. An international working group, representing distinct EpiSign Clinical Testing Network health jurisdictions, collaborated to establish recommendations for interpretation and reporting of episignature testing.

Systemic Oxidative Stress in Severe Early-Onset Fetal Growth Restriction Associates with Concomitant Pre-Eclampsia, Not with Severity of Fetal Growth Restriction.

Background: Placental insufficiency is an important mechanism underlying early-onset fetal growth restriction (eoFGR). Reduced placental function causes impaired metabolic and gaseous exchange. This unfavorable placental environment is among other processes characterized by increased oxidative stress.

Objective: To assess whether parental infertility is associated with differences in cardiometabolic trajectories in offspring.

Design: Pooled observational analysis in three prospective cohorts.

Setting: Three nationwide pregnancy cohorts.

Doxapram for apnoea of prematurity and neurodevelopmental outcomes at age 5-6 years.

Objective: To assess the long-term neurodevelopmental impact of doxapram for treating apnoea of prematurity.

Design: Secondary analysis of the French national cohort study EPIPAGE-2. Recruitment took place in 2011.

Germline specific genes increase DNA double-strand break repair and radioresistance in lung adenocarcinoma cells.

In principle, germline cells possess the capability to transmit a nearly unaltered set of genetic material to infinite future generations, whereas somatic cells are limited by strict growth constraints necessary to assure an organism's physical structure and eventual mortality. As the potential to replicate indefinitely is a key feature of cancer, we hypothesized that the activation of a "germline program" in somatic cells can contribute to oncogenesis. Our group recently described over one thousand germline specific genes that can be ectopically expressed in cancer, yet how germline specific processes contribute to the malignant properties of cancer is poorly understood.

Missed Proximal Tracheoesophageal Fistula (TEF) in a Neonate with Type D Esophageal Atresia.

We present the case of a patient with the rare type D esophageal atresia (EA), diagnosed after correction of an EA initially diagnosed as type C. Routine postoperative contrast esophagogram showed a missed proximal tracheoesophageal fistula. This case report illustrates the potential difficulties to diagnose type D EA.

Considering multifetal pregnancy reduction in triplet pregnancies: do we forget the emotional impact on fathers? A qualitative study from The Netherlands.

Study Question: What factors influence the decision-making process of fathers regarding multifetal pregnancy reduction or maintaining a triplet pregnancy, and how do these decisions impact their psychological well-being?

Summary Answer: For fathers, the emotional impact of multifetal pregnancy reduction or caring for triplets is extensive and requires careful consideration.

What Is Known Already: Multifetal pregnancy reduction is a medical procedure with the purpose to reduce the number of fetuses to improve chances of a healthy outcome for both the remaining fetus(es) and the mother, either for medical reasons or social considerations. Aspects of the decision whether to perform multifetal pregnancy reduction have been rarely investigated, and the impact on fathers is unknown.

Methods of induction of labor in women with obesity: A secondary analysis of two multicenter randomized controlled trials.

Introduction: Obesity is an increasing public health concern worldwide and can lead to more complications in pregnancy and childbirth. Women with obesity more often require induction of labor for various indications. The aim of this study is to assess which method of induction of labor is safest and most effective in women with obesity.

Transcutaneous electromyography as a tool to assess recovery of hemidiaphragmatic paresis: A case report.

In this case report, we describe two repeated transcutaneous electromyography of the diaphragm (dEMG) measurements in an infant with suspected paresis of the right hemidiaphragm after cardiac surgery. The first measurement, performed at the time of diagnosis, showed a lower electrical activity of the right side of the diaphragm in comparison with the left side. The second measurement, performed after a period of expectative management, showed that electrical activity of the affected side had increased and was similar to the activity of the left diaphragm.
