The noninvasive prenatal test (NIPT) for genetic screening has been adopted globally as an alternative to first-trimester and quad screening due to its high sensitivity and specificity. NIPT involves detecting and processing foreign fetal DNA in maternal circulation to screen for fetal aneuploidy. An incidental consequence of this process is the detection of foreign tumor cell DNA in maternal circulation in otherwise asymptomatic patients.

Methods: We performed a systematic review of literature involving an electronic search of the following databases: Ovid MEDLINE(R) and Epub Ahead of Print, In-Process and Other Non-Indexed Citations, Ovid MEDLINE(R) Daily, Ovid EMBASE, Ovid Cochrane Central Register of Controlled Trials, and Scopus.
3MC syndromes are rare heterogeneous autosomal recessive conditions previously designated as Mingarelli, Malpuech, Michels, and Carnevale syndromes, characterized by dysmorphic facial features, facial clefts, growth restriction, and intellectual disability. 3MC is secondary to mutations in the MASP1, MASP3, COLEC11, and COLEC10 genes. The number of patients with 3MC syndrome with known mutations in the COLEC11 or MASP1 is, to date, less than 50.

The COVID-19 pandemic represents the greatest challenge to date faced by the medical community in the 21st century. The rate of rapid dissemination, magnitude of viral contagiousness, person to person transmission at an asymptomatic phase of illness pose a unique and dangerous challenge for all patients, including neonatal and obstetric patients. Although scientific understanding of the pathophysiology of the disease, nature of transmission, and efficacy of mitigation strategies is growing, neither a cure or vaccine have been developed.

The effect of sub-chronic systemic IL-1β exposure in perinatal and offspring outcomes is unclear. The aim of this study was to examine the effects of maternal IL-1β exposure on pregnancy and offspring outcomes.

We hypothesized that blockade of P2X7 would prevent perinatal brain injury associated with exposure to intrauterine (IU) inflammation. Dams received 45 mg/kg of Brilliant Blue G (BBG), a specific P2X7 receptor (P2X7R) antagonist, on gestation day 17 (E17) prior to administration of lipopolysaccharide (LPS) or phosphate-buffered saline (PBS).

In this review, we highlighted the epidemiology and risk factors associated with syphilis. The incidence of syphilis in most populations showed a consistent upward trend until the 1940s with the introduction of penicillin as the preferred treatment.

Maternal infections, such as influenza and human immunodeficiency virus, have been linked to the development of autism spectrum disorders, differences in cognitive test scores, and bipolar disorder; an association that has been shown in both epidemiologic and retrospective studies. Several viral, bacterial, and parasitic illnesses are associated with alterations in fetal brain structural anomalies including brain calcifications and hydrocephalus.

The pathogenesis of PWMI targets premyelinating oligodendrocytes of the periventricular region secondary to free radicals, cytokine toxicity, and excitatory neurotransmitters. The primitive nature of the vasculature in the developing fetal cortex lends to its predilection to PWMI and cerebral ischemia with less arterial anastomoses at arterial border zones and failure to compensate for global hypotension, termed the "pressure-passive" circulation.
View Article and Find Full Text PDFThe study of preterm labor and prematurity has undergone a major transformation in its approach from an inevitable part of obstetrics with few answers to one in which science has led to knowledge and clinical intervention. Despite these advancements, understanding of preterm labor and prevention of prematurity is still limited. In the current review, we begin the discussion with fetal viability, first from a historical perspective and then from the understanding of this issue from a prospective of various professional organizations.

Methods: A retrospective cross-sectional study of 2735 fetuses was performed for standard biometry (biparietal diameter (BPD) and femoral diaphysis length (FDL)) and an assessment of menstrual age (MA). Standardized fetal echocardiographic measurements included aortic valve annulus and pulmonary valve annulus diameters at end-systole, right and left ventricular diameters at end-diastole, and cardiac circumference from a four-chamber view of the heart during end-diastole.
