We aimed to assess and compare the histological changes of grafts stored in Roswell Park Memorial Institute-1640 solution (RPMI), amniotic fluid (AF), and saline. Amniotic fluid which has abundant nutrients, proteins, and growth factors, and antimicrobial features may be an easily achievable and cheap alternative for the short term preservation of skin grafts. Discarded surgical skin pieces obtained from 15 trauma patients were divided into three groups as RPMI, AF, and saline. The specimens were evaluated at days 7, 14, 21, and 28 for histological alterations by a 3-point scoring scale. Histological scores in the grafts stored in amniotic fluid and RPMI were found significantly lower than those stored in saline (p<0.01). No significant difference was detected between AF and RPMI stored grafts. AF may be a good alternative for skin graft preservation as demonstrated by histological changes. New studies with multiple AF donators and repeated experiments will be worthwhile. Besides, restrictions of some ethical and legal issues for AF use should be solved.

To determine the basis for perinatal nutritional mismatch causing metabolic dysfunction associated steatotic liver disease (MASLD) and diabetes mellitus, we examined adult phenotype, hepatic transcriptome, and pancreatic β-islet function. In prenatal caloric restricted rat with intrauterine growth restriction (IUGR) and postnatal exposure to high fat with fructose (HFhf) or high carbohydrate (RC), we investigated male and female IUGR-Hfhf and IUGR-RC, versus HFhf and CON offspring. Males more than females displayed adiposity, glucose intolerance, insulin resistance, hyperlipidemia, hepatomegaly with hepatic steatosis.

Disruption of developmental processes affecting the fetal lung leads to pulmonary hypoplasia. Pulmonary hypoplasia results from several conditions including congenital diaphragmatic hernia (CDH) and oligohydramnios. Both entities have high morbidity and mortality, and no effective therapy that fully restores normal lung development.

Background: In cases of maternal primary infection with cytomegalovirus (CMV-MPI) maternal treatment with oral valaciclovir 8 g/day has been shown to reduce the risk of fetal infection. The pharmacological profile of this high dosage during pregnancy is not yet known.
Objectives: To quantify maternal-fetal exposure to valaciclovir 8 g/day in a population pharmacokinetic (popPK) study.
Assessing Second Trimester Ferning in Diagnosing Preterm Prelabor Rupture of Membranes.
Am J Perinatol

MFM, Albany Medical Center, Albany, United States.
Preterm prelabor rupture of membranes (PPROM) diagnosis is made through visualization of amniotic fluid (pooling), nitrizine testing, sonographic low amniotic fluid, and microscopic detection of amniotic fluid arborization (ferning). Data exits on the specificity and sensitivity of ferning detection but has not focused on the second trimester. Our objective is to evaluate the presence of ferning in transvaginally collected amniotic fluid in pregnancies with known second trimester PPROM to determine if there is a difference in ferning based on gestational age and sample drying time.

Amniotic fluid assessment is crucial in prenatal ultrasound to monitor fetal conditions, with polyhydramnios, characterized by excessive amniotic fluid, affecting 1%-2% of pregnancies. Polyhydramnios is linked to complications such as placental abruption, preterm labor, congenital anomalies, and postpartum hemorrhage, emphasizing the need for early detection and management. While idiopathic causes account for 60%-70% of cases, other causes include impaired fetal swallowing and increased urine production due to maternal, fetal, and placental conditions.
