    Congenital heart disease and genetic syndromes: new insights into molecular mechanisms.
    Expert Rev Mol Diagn 2017 Sep 3;17(9):861-870. Epub 2017 Aug 3.
    b Department of Pediatrics , Sapienza University , Rome , Italy.
    Introduction: Advances in genetics allowed a better definition of the role of specific genetic background in the etiology of syndromic congenital heart defects (CHDs). The identification of a number of disease genes responsible for different syndromes have led to the identification of several transcriptional regulators and signaling transducers and modulators that are critical for heart morphogenesis. Understanding the genetic background of syndromic CHDs allowed a better characterization of the genetic basis of non-syndromic CHDs. Read More

    Endocrinology Service, Department of Biomedical Sciences, University of Milan, IRCCS Istituto Ortopedico Galeazzi, Milan, Italy. Electronic address:
    Hypothyroidism may occur in association with congenital parathyroid disorders determining parathyroid hormone insufficiency, which is characterized by hypocalcemia and concomitant inappropriately low secretion of parathormone (PTH). The association is often due to loss of function of genes common to thyroid and parathyroid glands embryonic development. Hypothyroidism associated with hypoparathyroidism is generally mild and not associated with goiter; moreover, it is usually part of a multisystemic involvement not restricted to endocrine function as occurs in patients with 22q11 microdeletion/DiGeorge syndrome, the most frequent disorders.

    Laboratory of Animal Developmental Biology, College of Life Science, Northeast Forestry University, Harbin, Heilongjiang Province 150040, China.
    Both microRNAs (miRNAs) and endogenous small interfering RNAs (endo-siRNAs) play key regulatory roles in gene expression. Some studies have demonstrated that the function of miRNA is suppressed in mouse oocytes, suggesting that endo-siRNA, not miRNA, is essential for female meiosis. This finding has yet to be confirmed in other species. Read More

    In schizophrenia, brain-wide alterations have been identified at the molecular and cellular levels, yet how these phenomena affect cortical circuit activity remains unclear. We studied two mouse models of schizophrenia-relevant disease processes: chronic ketamine (KET) administration and Df(16)A(+/-), modeling 22q11.2 microdeletions, a genetic variant highly penetrant for schizophrenia.

    Social cognitive impairment in 22q11 deletion syndrome: A review.
    Psychiatry Res 2017 Jul 23;253:99-106. Epub 2017 Feb 23.
    Department of Psychiatry, Boston Children's Hospital, 300 Longwood Avenue, Boston, MA 02115, United States; Department of Psychiatry, Harvard Medical School, 25 Shattuck Street, Boston, MA 02115, United States.
    Individuals with 22q11.2 deletion syndrome (22q11DS) exhibit a broad array of physical and psychiatric features, of which impaired social cognition and poor social functioning are common. This review seeks to (1) characterize the current understanding of impairment across social cognitive domains in the context of 22q11DS, and (2) synthesize the relevant literature on social cognition and psychosis, given that the prevalence of psychosis in 22q11DS is especially high compared to the general population.

    Programmatic Approach to Management of Tetralogy of Fallot With Major Aortopulmonary Collateral Arteries: A 15-Year Experience With 458 Patients.
    Circ Cardiovasc Interv 2017 Apr;10(4)
    From the Departments of Pediatrics (H.B.-H., A.B., B.H., M.L., R.A., A.K., C.A.A., S.B.P., A.S., L.F.P., D.B.M.), Anesthesia (L.D., L.W.-F.), and Cardiothoracic Surgery (F.L.H., D.B.M.), Lucile Packard Children's Hospital Heart Center Clinical and Translational Research Program, Stanford University School of Medicine, Palo Alto, CA.
    Background: Tetralogy of Fallot with major aortopulmonary collateral arteries is a complex and heterogeneous condition. Our institutional approach to this lesion emphasizes early complete repair with the incorporation of all lung segments and extensive lobar and segmental pulmonary artery reconstruction.

    Methods And Results: We reviewed all patients who underwent surgical intervention for tetralogy of Fallot and major aortopulmonary collateral arteries at Lucile Packard Children's Hospital Stanford (LPCHS) since November 2001. Read More
