Pregnancy in women with a Fontan circulation: Short and long-term outcomes.

Background: The Fontan circulation procedure is the palliative surgery of choice for patients with single ventricle physiology, many of whom are now reaching childbearing age due to advances in care. Our study examines the impact of pregnancy on women with Fontan circulation, assessing both short and long-term outcomes.

Methods: We retrospectively analysed pregnancies in women with Fontan circulation at our centre from 2005 to 2023, including a matched non-pregnant, nulliparous cohort for comparison.

Multifaceted Fontan Patients and Their Response to Pregnancy.

We present 4 patients with Fontan circulation who underwent successful pregnancies, albeit with complications that required close monitoring and timely intervention. Each Fontan patient presents with a unique clinical picture, making risk stratification challenging but all the more important.

SARS-CoV-2 hampers dopamine production in iPSC-derived dopaminergic neurons.

An increasing number of patients experiences prolonged symptoms, whose profile and timeline remain uncertain, a condition that has been defined as post COVID. The majority of recovered hospitalized patients manifests at least one persistent symptom even sixty days after the first clinical manifestation's onset. Particularly, in light of the COVID-19-related symptomatology, it has been hypothesized that SARS-CoV-2 might affect the dopamine pathway.

Gangliosides and Cell Surface Ganglioside Metabolic Enzymes in the Nervous System.

Gangliosides are a large group of complex lipids found predominantly in the outer layer of the plasma membrane of cells, particularly abundant in nerve endings. Their half-life in the nervous system is short, and their membrane composition and content are strictly connected to their metabolism. The neobiosynthesis of gangliosides starts in the endoplasmic reticulum and is completed in the Golgi apparatus, whereas catabolism occurs primarily in lysosomes.
