American Bar Association Criminal Justice Section Report to the House of Delegates

The proposed amendments to the Federal Rules of Evidence, Rules 413-15 regarding the admission of character testimony in cases of sexual abuse and child molestation, have been roundly criticized by the legal community on both substantive and procedural grounds. The ABA has resolved to oppose the substance of these rules, and fear that in addition to the direct concerns regarding the result of the rules, they raise troubling policy issues going forward

Oxidative stress and endothelial function in normal pregnancy versus pre-eclampsia, a combined longitudinal and case control study

Background: Pre-eclampsia (PE) is related to an impaired endothelial function. Endothelial dysfunction accounts for altered vascular reactivity, activation of the coagulation cascade and loss of vascular integrity. Impaired endothelial function originates from production of inflammatory and cytotoxic factors by the ischemic placenta and results in systemic oxidative stress (OS) and an altered bioavailability of nitric oxide (·NO). The free radical ·NO, is an endogenous endothelium-derived relaxing factor influencing endothelial function. In placental circulation, endothelial release of ·NO dilates the fetal placental vascular bed, ensuring feto-maternal exchange. The Endopreg study was designed to evaluate in vivo endothelial function and to quantify in vitro OS in normal and pre-eclamptic pregnancies. Methods/design: The study is divided into two arms, a prospective longitudinal study and a matched case control study. In the longitudinal study, pregnant patients ≥18 years old with a singleton pregnancy will be followed throughout pregnancy and until 6 months post-partum. In the case control study, cases with PE will be compared to matched normotensive pregnant women. Maternal blood concentration of superoxide (O2·) and placental concentration of ·NO will be determined using EPR (electron paramagnetic resonance). Endothelial function and arterial stiffness will be evaluated using respectively Peripheral Arterial Tonometry (PAT), Flow-Mediated Dilatation (FMD) and applanation tonometry. Placental expression of eNOS (endothelial NOS) will be determined using immune-histochemical staining. Target recruitment will be 110 patients for the longitudinal study and 90 patients in the case-control study. Discussion: The results of Endopreg will provide longitudinal information on in vivo endothelial function and in vitro OS during normal pregnancy and PE. Adoption of these vascular tests in clinical practice potentially predicts patients at risk to develop cardiovascular events later in life after PE pregnancies. ·NO, O2·- and eNOS measurements provide further inside in the pathophysiology of PE

Oxidative stress in healthy pregnancy and preeclampsia is linked to chronic inflammation, iron status and vascular function

Background During normal pregnancy, placental oxidative stress (OS) is present during all three trimesters and is necessary to obtain normal cell function. However, if OS reaches a certain level, pregnancy complications might arise. In preeclampsia (PE), a dangerous pregnancy specific hypertensive disorder, OS induced in the ischemic placenta causes a systemic inflammatory response and activates maternal endothelial cells. In this study, we aimed to quantify superoxide concentrations (as a measure of systemic OS) using electron paramagnetic resonance (EPR) and correlate them to markers of systemic inflammation, iron status and vascular function. Methods Fifty-nine women with a healthy pregnancy (HP), 10 non-pregnant controls (NP) and 28 PE patients (32±3.3weeks) were included. During HP, blood samples for superoxide, neutrophil to lymphocyte ratio (NLR), mean platelet volume (MPV) and iron status were taken at 10, 25 and 39 weeks. Vascular measurements for arterial stiffness (carotid-femoral pulse wave velocity (CF-PWV), augmentation index (AIx), augmentation Pressure (AP)) and microvascular endothelial function (reactive hyperemia index (RHI)) were performed at 35 weeks. In PE, all measurements were performed at diagnosis. CMH (1-hydroxy-3-methoxycarbonyl-2,2,5,5-tetramethylpyrrolidine) was used as spin probe for EPR, since the formed CM radical corresponds to the amount of superoxide. Results Superoxide concentration remains stable during pregnancy (p = 0.92), but is significantly higher compared to the NP controls (p<0.0001). At 25 weeks, there is a significant positive correlation between superoxide and ferritin concentration. (p = 0.04) In PE, superoxide, systemic inflammation and iron status are much higher compared to HP (all p<0.001). During HP, superoxide concentrations correlate significantly with arterial stiffness (all p<0.04), while in PE superoxide is significantly correlated to microvascular endothelial function (p = 0.03). Conclusions During HP there is an increased but stable oxidative environment, which is correlated to ferritin concentration. If superoxide levels increase, there is an augmentation in arterial stiffness. In PE pregnancies, systemic inflammation and superoxide concentrations are higher and result in a deterioration of endothelial function. Together, these findings support the hypothesis that vascular function is directly linked to the amount of OS and that measurement of OS in combination with vascular function tests might be used in the prediction of PE

Relapsing fetal bilateral hydrothorax, an isolated expression of a vein of Galen aneurysmal malformation

We report a case of bilateral fetal hydrothorax presenting at 20 weeks of pregnancy, spontaneously resolving at 22 weeks and severely relapsing at 28 weeks in a fetus with normal karyotype. The cause was a high-output heart failure caused by vein of Galen malformation

Use of ticagrelor in human pregnancy, the first experience

Ticagrelor was daily administered throughout pregnancy to a 37-year-old pregnant woman until 36 weeks of gestation. The patient, with Behçet disease, suffered from a non-ST elevation myocardial infarction 4 months before conception, possibly related to hypertension and tobacco abuse. Pregnancy and postpartum periods were uneventful. She delivered a healthy but small-for-gestational-age term neonate

A rare cause of primary amenorrhoea, the XY female with gonadal dysgenesis

Disorders of sexual development are conditions where sexual phenotype and genotype are discordant. Genetic sex is determined at conception as the ovum is fertilised by a spermatozoon that contains either an X or Y chromosome. A complex pathway determined by genes and hormones leads to gonadal differentiation into testis or ovary and promotes the development of internal and external genitalia. We present a case of an 18-year-old woman who presented with primary amenorrhoea. She was a virgin, and apart from hirsutism and overweight, had no complaints. Her family history was insignificant. The patient was tall and had underdeveloped breasts. Her blood results showed hypergonadotropic hypogonadism. A 46, XY genotype was detected with karyotype analysis. Ultrasound and MRI demonstrated the presence of a uterus, but no overt gonads. Laparoscopy was performed, with bilateral removal of streak ovaries
