We report a case of 34-year patient who had uncomplicated elective caesarean-section. Postoperatively, she developed sudden hypotension, bradycardia, dyspnea and disseminated intravascular coagulation (DIC), all signs associated with amniotic fluid embolism (AFE). Echocardiogram showed signs of acutely increased right ventricular after load including McConell's sign, i.e. right ventricular dilatation, segmental hypokinesia (mid-right ventricular) and hypercontractile right ventricular apex and overall right ventricular dysfunction. Similarly, 60/60 sign was positive on chocardiography (decreased right ventricular acceleration time of less than 60 milli-seconds and pulmonary artery systolic pressure of less than 60 mmHg). Performance of CT pulmonary angiogram failed to show any clear thromboembolic phenomenon; although, there were other indirect signs pointing towards the diagnosis. She was treated with aggressive supportive care without anticoagulation and she showed complete recovery, with follow-up echocardiogram becoming absolutely normal after 9 days with normalization of right ventricular size and function and improvement in 60/60 sign.

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.

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.

Extracellular vesicles (EVs) are a heterogeneous group of membrane-encapsulated vesicles released by cells into the extracellular space. They play a crucial role in intercellular communication by transporting bioactive molecules such as proteins, lipids, and nucleic acids. EVs can be detected in body fluids, including blood plasma, urine, saliva, amniotic fluid, breast milk, and pleural ascites.

Polyethylene terephthalate (PET) is a widely utilized synthetic polymer, favored in various applications for its desirable physicochemical characteristics and widespread accessibility. However, its extensive utilization, coupled with improper waste disposal, has led to the alarming pollution of the environment. Thus, recycling PET products is essential for diminishing global pollution and turning waste into meaningful materials.
