The Impact of Hepatitis C Virus Infection on Buprenorphine Dose in Pregnancy.

Objective: Buprenorphine (BUP) is commonly used for opioid maintenance therapy in pregnancy. Our goal was to determine whether liver dysfunction related to hepatitis C virus (HCV) infection impacts BUP dosing requirements in pregnancy.

Study Design: This was a retrospective cohort study of pregnant women with antenatal exposure to BUP to compare dosing between individuals positive versus negative for HCV infection.

The Impact of CenteringPregnancy Group Prenatal Care on Birth Outcomes in Medicaid Eligible Women.

CenteringPregnancy group prenatal care (GPNC) has been shown to reduce rates of preterm birth (PTB). We evaluated the impact of GPNC on spontaneous PTB (sPTB) as a first step in exploring the possible mechanism by which GPNC may decrease rates of PTB. We also evaluated whether attending more than five GPNC sessions affected PTB risk and examined all differences by race/ethnicity.

Lymphovascular space invasion in uterine corpus cancer: What is its prognostic significance in the absence of lymph node metastases?

Objective: Lymphovascular space invasion (LVSI) is a poor prognostic indicator in uterine cancer, primarily due to its association with lymph node metastases. We sought to determine if LVSI provides any prognostic information for uterine cancer subjects in the absence of nodal disease.

Methods: A retrospective review was performed using a database of women treated for uterine cancer at MUSC from 2005 to 2012.

Calpain inhibitor attenuated optic nerve damage in acute optic neuritis in rats.

Optic neuritis (ON), which is an acute inflammatory autoimmune demyelinating disease of the central nervous system (CNS), often occurs in multiple sclerosis (MS). ON is an early diagnostic sign in most MS patients caused by damage to the optic nerve leading to visual dysfunction. Various features of both MS and ON can be studied following induction of experimental autoimmune encephalomyelitis (EAE), an animal model of MS, in Lewis rats.

Neuroprotective effects of genistein in VSC4.1 motoneurons exposed to activated microglial cytokines.

Pro-inflammatory cytokines released from activated microglia may be responsible for neuronal damage and resulting motor deficits associated with CNS disorders such as spinal cord injury, Parkinson's disease, and multiple sclerosis. Estrogen (17β-estradiol) is capable of ameliorating motoneuron death following spinal cord injury, but has a number of deleterious side effects. Genistein (GEN), an estrogen receptor beta agonist and potent antioxidant, may represent an alternative to estrogen in treating neurodegenerative disorders.

Post-treatment with voltage-gated Na(+) channel blocker attenuates kainic acid-induced apoptosis in rat primary hippocampal neurons.

Injection of rats with kainic acid (KA), a non-N-methyl-D-aspartate (NMDA) type glutamate receptor agonist, induces recurrent (delayed) convulsive seizures and subsequently hippocampal neurodegeneration, which is reminiscent of human epilepsy. The protective effect of anti-epileptic drugs on seizure-induced neuronal injury is well known; however, molecular basis of this protective effect has not yet been elucidated. In this study, we investigated the effect and signaling mediators of voltage-gated Na(+) channel blockers (Lamotrigine, Rufinamide, Oxcarbazepine, Valproic Acid, and Zonisamide) on KA-induced apoptosis in rat primary hippocampal neurons.

The inhibition of apoptosis by melatonin in VSC4.1 motoneurons exposed to oxidative stress, glutamate excitotoxicity, or TNF-alpha toxicity involves membrane melatonin receptors.

Loss of motoneurons may underlie some of the deficits in motor function associated with the central nervous system (CNS) injuries and diseases. We tested whether melatonin, a potent antioxidant and free radical scavenger, would prevent motoneuron apoptosis following exposure to toxins and whether this neuroprotection is mediated by melatonin receptors. Exposure of VSC4.
