Approximately 3% of pregnant women have sickle cell disease (SCD). COVID-19, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), became a global pandemic in March 2020, resulting in more than 3,500 deaths in Jamaica by April 2023. Sickle cell disease is an immunocompromised state; therefore, contracting COVID-19 may result in adverse maternal/neonatal outcomes.

Objectives: Sickle cell disease (SCD) occurs in 2.8 % of our Jamaican antenatal population with homozygous HbSS being most associated with adverse maternal and perinatal outcomes.

Methods: A retrospective comparative analysis of HbSS, HbSC and HbSβThal pregnancy outcomes at the University Hospital of the West Indies (UHWI) between January 2012 and December 2022 was conducted.

Objective: To determine and predict the maternal and neonatal outcomes of pregnancies occurring in patients with cardiac disease.

Method: This retrospective review included 147 pregnancies identified from antenatal, delivery, and nursery records. Information concerning the nature and severity of the pre-existing cardiac disease, comorbidities, risk scores, obstetric or cardiac complications, and pregnancy outcomes were collected.

Background: Systemic Lupus Erythematosus (SLE) is a chronic autoimmune multi-system disorder frequently affecting black women of childbearing age. No published data exist on the obstetric outcomes in a Caribbean population.

Objective: We analyzed pregnancy outcomes in an Afro-Caribbean cohort of women with SLE at a tertiary university hospital.

Background: Subclinical hypothyroidism (SCH) has been reported to be associated with adverse pregnancy outcomes, however universal screening and treatment is controversial.

Objectives: Our objectives were to determine population-specific pregnancy reference values (R1) for serum thyroid-stimulating hormone (TSH) and free thyroxine (FT4) at 14 weeks' gestation, along with the prevalence of SCH and thyroid peroxidase antibody (TPOAb).

Methods: This was a prospective hospital-based cohort study.

Background: Congenital giant neck teratomas are rare tumours associated with high perinatal mortality. Recent advances in prenatal diagnosis and delivery by ex utero intrapartum treatment (EXIT) have improved perinatal outcome.

Case: An otherwise healthy 32-year-old woman, gravida 3, para 2, was referred to our institution at 25 weeks' gestation with a diagnosis of a fetal giant cervical teratoma.

Objective: To determine the obstetric outcomes of women diagnosed with a primary intracranial neoplasm prior to or during pregnancy and the puerperium.

Methods: Demographic data, neurologic, obstetric, and neonatal outcomes were extracted retrospectively from charts identified from two hospital databases.

Results: Twenty-two patients with 25 pregnancies were identified.

A variety of lines of converging evidence implicate the prefrontal cortex (PFC) in schizophrenia. Studies employing Nissl stains have suggested that PFC dendrites may be atrophic in schizophrenia; however, Nissl stains do not reveal dendrites. We employed MAP2 immunocytochemistry, which stains dendrites to examine cortical layers III and V in two areas of the PFC (areas 9 and 32).
