Detailed analysis of cystic lesions in patients after open fetal repair and postnatal myelomeningocele closure.

Purpose: We sought to evaluate the incidence, natural history, and management of cystic spinal lesions following myelomeningocele/myeloschisis closure.
Methods: We performed a single-center retrospective review of all patients who underwent myelomeningocele/myeloschisis closure from 2013 to 2018 with follow-up to 5 years old.
Results: We analyzed 100 fetal repairs and 81 postnatal closures from 305 total surgeries.
Evaluation of long-acting cabotegravir safety and pharmacokinetics in pregnant women in eastern and southern Africa: a secondary analysis of HPTN 084.

Introduction: Long-acting injectable cabotegravir (CAB-LA) for pre-exposure prophylaxis significantly reduced HIV acquisition in HPTN 084. We report on the safety and CAB-LA pharmacokinetics in pregnant women during the blinded period of HPTN 084.
Methods: Participants were randomized 1:1 to either active cabotegravir (CAB) plus tenofovir disoproxil fumarate/emtricitabine (TDF/FTC) placebo or active TDF/FTC plus CAB placebo.
Single-cell RNA sequencing identifies CXADR as a fate determinant of the placental exchange surface.

The placenta is the critical interface between mother and fetus, and consequently, placental dysfunction underlies many pregnancy complications. Placental formation requires an adequate expansion of trophoblast stem and progenitor cells followed by finely tuned lineage specification events. Here, using single-cell RNA sequencing of mouse trophoblast stem cells during the earliest phases of differentiation, we identify gatekeepers of the stem cell state, notably Nicol1, and uncover unsuspected trajectories of cell lineage diversification as well as regulators of lineage entry points.

Objectives: Maternal protein malnutrition alters brain functioning, impairing fetal development. Physical exercise during gestation benefits the fetal organism from maternal adaptive changes that may be neuroprotective. This study evaluated the effect of a low-protein diet associated with maternal voluntary physical activity (VPA) on rats' behavioral and brain electrophysiological parameters in the mother-pup dyad.

As a ubiquitous feature of the biological world, gradation, in either composition or structure, is essential to many functions and processes. Taking protein gradation as an example, it plays a pivotal role in the development and evolution of human bodies, including stimulation and direction of the outgrowth of peripheral nerves in a developing fetus. It is also critically involved in wound healing by attracting and guiding immune cells to the site of injury or infection.
