Neonatal Cardiac Arrest From Left Ventricular Cardiac Hemangioma: A Surprising Presentation

Cardiac hemangioma is rare, even more when leading to a cardiovascular collapse in a seemingly healthy newborn. A 6-day-old neonate had a tamponade caused by a basolateral hemangioma of the left ventricle. Partial surgical resection was performed. A congenital lobular capillary hemangioma was diagnosed upon histologic examination. The patient recovered completely and shows normal development at the 12-month follow-up.     

Protein Content and Methyl Donors in Maternal Diet Interact to Influence the Proliferation Rate and Cell Fate of Neural Stem Cells in Rat Hippocampus

Maternal diet during pregnancy and early postnatal life influences the setting up of normal physiological functions in the offspring. Epigenetic mechanisms regulate cell differentiation during embryonic development and may mediate gene/environment interactions. We showed here that high methyl donors associated with normal protein content in maternal diet increased the in vitro proliferation rate of neural stem/progenitor cells isolated from rat E19 fetuses. Gene expression on whole hippocampi at weaning confirmed this effect as evidenced by the higher expression of the Nestin and Igf2 genes, suggesting a higher amount of undifferentiated precursor cells. Additionally, protein restriction reduced the expression of the insulin receptor gene, which is essential to the action of IGFII. Inhibition of DNA methylation in neural stem/progenitor cells in vitro increased the expression of the astrocyte-specific Gfap gene and decreased the expression of the neuron-specific Dcx gene, suggesting an impact on cell differentiation. Our data suggest a complex interaction between methyl donors and protein content in maternal diet that influence the expression of major growth factors and their receptors and therefore impact the proliferation and differentiation capacities of neural stem cells, either through external hormone signals or internal genomic regulation.     

The screen for cognitive impairment in psychiatry (SCIP) is associated with disease severity and cognitive complaints in major depression

Objective: To assess the relationship between the Screen for Cognitive Impairment in Psychiatry (SCIP) score and illness severity, subjective cognition and functioning in a cohort of major depressive disorder (MDD) patients.

Methods: Patients (n?=?40) diagnosed with MDD (DSM-IV-TR) completed the SCIP, a brief neuropsychological test, and a battery of self-administered questionnaires evaluating functioning (GAF, SDS, WHODAS 2.0, EDEC, PDQ-D5). Disease severity was evaluated with the Hamilton Depression Rating Scale (HDRS) and the Clinical Global Impression (CGI).

Results: Age and sex were associated with performance in the SCIP. The SCIP-Global index score was associated with disease severity (r?=??0.316, p?<?.05), the SDS, a patient self-assessment of daily functioning (r?=??0.368, p?<?.05), and the EDEC subscales of patient-reported cognitive deficits (r?=??0.388, p?<?.05) and their functional impacts (r?=??0.335, p?<?.05). Multivariate analysis adjusted for age and sex confirmed these tests are independent predictors of performance in the SCIP (CGI-S, F_[3,34]?=?4.478, p?=?.009; SDS, F_[3,34]?=?3.365, p?=?.030; EDEC-perceived cognitive deficits, F_[3,34]?=?5.216, p?=?.005; EDEC-perceived impacts of functional impairment, F_[3,34]?=?5.154, p?=?.005).

Conclusions: This study confirms that the SCIP can be used during routine clinical evaluation of MDD, and that cognitive deficits objectively assessed in the SCIP are associated with disease severity and self-reported cognitive dysfunction and impairment in daily life.
