The paradox of pregnancy : an update on the immunology of early pregnancy [PDF]

open access: yes, 2008
Pregnancy is an altered physiological state where an organism essentially foreign to the individual carrying it, grows, develops and at an appropriate time probably initiates a series of signals which lead to its safe expulsion from the woman's body. The

Maternal Factors Modifying the Link Between Genetic Risk for Autism and Developmental Milestones

open access: yesAmerican Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Although common genetic liability—quantified through polygenic risk scores (PRS)—accounts for substantial variance in autism spectrum disorder (ASD) liability, how prenatal environmental exposures interact with genetic predisposition to shape developmental outcomes remains poorly understood. Using the data from Autism Genetic Resource Exchange

Overview on current approach on recurrent miscarriage and threatened miscarriage

open access: yes, 2020
Miscarriage is a frequent outcome of pregnancy, with major emotional implications to the couple experiencing such an event. Threatened miscarriage is the commonest complication of early pregnancy and affects about 20% of pregnancies.

Prenatal Presentation of RMRP‐Related Skeletal Dysplasia: Clinical and Genomic Expansion

open access: yesAmerican Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT The RNA subunit of the mitochondrial RNA processing endoribonuclease complex is encoded by RMRP. Biallelic variants in RMRP are known for anauxetic dysplasia 1 (AD), cartilage‐hair hypoplasia (CHH), and metaphyseal dysplasia without hypotrichosis.

Prenatal Evaluation of RNU4‐2 Variants in Fetuses With Central Nervous System Anomalies

open access: yesAmerican Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Fetal central nervous system (CNS) anomalies are among the most common congenital malformations, yet the overall prenatal diagnostic yield of current genetic testing remains below 40%. Variants in RNU4‐2, a non‐coding gene encoding the U4 small nuclear RNA (snRNA), have recently been linked to a novel highly recurrent dominant ...

Effect of Cyclosporine A in treatment of Unexplained Recurrent Spontaneous Miscarriage

open access: yesMinia Journal of Medical Research
Background: Unexplained recurrent spontaneous miscarriage (URSM) remains a major reproductive challenge. Aim: To evaluate the effectiveness and safety of Cyclosporine A in improving pregnancy outcomes among women with unexplained recurrent spontaneous ...

Twin pregnancies and the limits of the energetics of gestation and growth hypothesis

open access: yesThe Anatomical Record, EarlyView.
Abstract The “Energetics of Gestation and Growth” (EGG) hypothesis proposes that human birth timing and the associated secondary altriciality of human newborns is determined by limits in maternal metabolic capacity. According to this model, labor is triggered when the increasing fetal energy requirements exceed the expectant mother's maximum sustained ...

“White spots” in the diagnostic search for the causes of recurrent miscarriage

open access: yesМедицинский вестник Юга России
Recurrent pregnancy loss is not only a medical, but also a social problem of a multifactorial nature. This problem remains unsolvable despite the constant search and application of new diagnostic and therapeutic strategies.

The mechanism of labor in nonhuman primates: A look inside

open access: yesThe Anatomical Record, EarlyView.
Abstract While in humans, the flexed position of the fetus and its rotating course down the birth canal are well documented, in other primates the mechanism of labor is unknown. Despite the lack of comparative data, it is commonly assumed that the human obstetric mechanism is unique, and anthropologists have disputed when and why the transition to the ...

The “costly son” hypothesis: Sons exacerbate obstetrical dilemmas in humans and other mammals

open access: yesThe Anatomical Record, EarlyView.
Abstract Human childbirth has often been considered uniquely difficult among mammals, yet recent evidence suggests that obstructed labor and fetopelvic disproportion are widespread across placental mammals. Here, we propose the “costly son” hypothesis: because male offspring are typically larger at birth, they impose greater obstetric risk on mothers ...
