Relationship between pre-pregnancy body-mass-index and gestational age-specific risk of stillbirth and perinatal death in women with chronic hypertension.

Background: Obesity is a risk factor for stillbirth and perinatal death and is often accompanied by chronic hypertension; however, there are few studies on the relationship between pre-pregnancy BMI and gestational age (GA)-specific rates of stillbirth and perinatal death in women with chronic hypertension.

Objective: The objective of this study was to examine the relationship between pre-pregnancy BMI and GA-specific risk of stillbirth and perinatal death in the presence/absence of chronic hypertension.

Methods: This was a retrospective cohort study of all singleton births in the United States in 2016-17.

Assessment of Incidence and Character of Neurologic/ Neuropsychiatric Complications in a Group of Patients with Malignant Melanoma Treated with Adjuvant High Dose Interferon.

Background: Authors describe the incidence and character of neurologic and neuropsychiatric complications - particularly depression and parkinsonism - during adjuvant treatment of malignant melanoma (MM) with high dose interferon (HDI). Among the most frequently observed side effects are fatigue, hematotoxicity, and hepatotoxicity. Most research has been directed at depression and parkinsonism because of the lack of literature concerning these complications.

Studies on the kinetic stabilities of the Gd(3+) complexes formed with the N-mono(methylamide), N'-mono(methylamide) and N,N"-bis(methylamide) derivatives of diethylenetriamine-N,N,N',N",N"-pentaacetic acid.

High kinetic stability is an important requirement for the Gd(3+) complexes used as contrast enhancement agents in magnetic resonance imaging. The kinetic stabilities of the Gd(3+) complexes formed with DTPA-N-mono(methylamide) (L(3)), DTPA-N'-mono(methylamide) (L(2)) and DTPA-bis(methylamide) (L(1)) are characterized by the rates of the exchange reactions with Eu(3+) and the endogenous Cu(2+) and Zn(2+). The exchange reactions occur via the proton-assisted dissociation of the complexes and direct attack of the exchanging metal ions on the complex.

The rates of the exchange reactions between [Gd(DTPA)]2- and the endogenous ions Cu2+ and Zn2+: a kinetic model for the prediction of the in vivo stability of [Gd(DTPA)]2-, used as a contrast agent in magnetic resonance imaging.

The kinetic stability of the complex [Gd(DTPA)]2- (H5DTPA = diethylenetriamine-N,N,N',N",N"-pentaacetic acid), used as a contrast-enhancing agent in magnetic resonance imaging (MRI), is characterised by the rates of the exchange reactions that take place with the endogenous ions Cu2+ and Zn2+. The reactions predominantly occur through the direct attack of Cu2+ and Zn2+ on the complex (rate constants are 0.93+/-0.
