OBJECTIVE: Hypertensive disorders of pregnancy (HDP) are associated with impaired placentation, as evidenced by abnormal uterine artery (UtA) Doppler. UtA mean pulsatility index (PI) shows a progressive decline with gestational age (GA). However, previous studies have reported that a proportion of pregnancies demonstrate worsening of the UtA Doppler. The aim of this study was to investigate the incidence of HDP according to the change in the UtA mean PI between the second and third trimester...

Little research has examined the friendships of lesbian parents, especially within the context of children's schools. This study of 40 lesbian adoptive parents (20 couples) focused on their relationships with other parents in the school community and how sexual orientation, race, and class dynamics impacted these relationships. Half of the participants described friendships with parents at the school, sometimes in spite of demographic differences, whereas others felt disconnected due to these differences. Outside of school, most participants reported friendships with other lesbian/gay parents...

INTRODUCTION: Metal-on-metal (MoM) hip replacement bearings produce metallic ions that can cause health complications. Metallic release also occurs with other materials, but data on metallic ion levels after knee arthroplasty are sparse. We postulate that knee replacement generates elevating metallic ions (chromium (Cr), cobalt (Co) and titanium (Ti)) during the first year after implantation. PATIENTS AND METHODS: This ongoing prospective study included all patients who underwent the same type of knee arthroplasty between May and December 2013...

Metal-on-metal (MoM) bearings have become popular due to a major advantage over metal-on-polymer bearings for total hip arthroplasty in that the larger femoral head and hydrodynamic lubrication of the former reduce the rate of wear. However, concerns remain regarding adverse reactions to metal debris including metallosis caused by metal wear generated at the taper-head interface and another modular junction. Our group has hypothesized that carbon ion implantation (CII) may improve metal wear properties. The purpose of this study was to investigate the wear properties and friction coefficients of CII surfaces with an aim to ultimately apply these surfaces to MoM bearings in artificial joints...

To analyze the characters of Down syndrome (DS) who failed to be diagnosed after prenatal screening and hope to be able to improve the programs of prenatal screening and reduce the missed diagnosis of DS. In this multicenter study, we collected the missed cases from 3 prenatal diagnosis centers and analyzed their characters. A total of 126 DS babies failed to be diagnosed after prenatal screening. Their mothers accepted the prenatal screening in second trimester. We collected the mothers' blood and detected the levels of alpha-fetoprotein (AFP) and the free beta subunit of human chorionic gonadotropin (fβhCG) by time-resolved fluoroimmunoassay...

OBJECTIVE: To determine the performance of a five (5) serum marker plus ultrasound screening protocol for T21, T18 and T13. METHOD: Specimens from 331 unaffected, 34 T21, 19 T18 and 8 T13 cases were analyzed for free Beta hCG, PAPP-A, AFP, PlGF and dimeric inhibin A (DIA). Gaussian distributions of MoM values were used to estimate modeled false positive and detection rates. RESULTS: For T21, at a 1/300 risk cut-off, detection rate of screening with all five serum markers along with nuchal translucency and nasal bone was 98% at a 1...

This study assessed the correlation between the magnitude of the elevation in maternal serum human chorionic gonadotropin (MShCG) levels and pregnancy complications. Among 80,716 screened pregnancies, 120 with moderately elevated MShCG (3.00-5.99 MoM) were compared to 84 with extremely elevated MShCG >6.00 MoM. A control series of 120 women with normal MShCG (<3.00 MoM) were matched. Rates of intrauterine growth restriction, preterm labour, antepartum foetal death (APFD), pre-eclampsia, and placental abruption were analysed...

Depression is one of the most prevalent and debilitating psychiatric disorders worldwide. Recently, we showed that both relatively short and relatively long cytosine-adenine-guanine (CAG) repeats in the huntingtin gene (HTT) are associated with an increased risk of lifetime depression. However, to what extent the variations in CAG repeat length in the other eight polyglutamine disease-associated genes (PDAGs) are associated with depression is still unknown. We determined the CAG repeat sizes of ATXN1, ATXN2, ATXN3, CACNA1A, ATXN7, TBP, ATN1 and AR in two well-characterized Dutch cohorts-the Netherlands Study of Depression and Anxiety and the Netherlands Study of Depression in Older Persons-including 2165 depressed and 1058 non-depressed individuals-aged 18-93 years...

PURPOSE: Donor breastmilk (DBM) has gained popularity as an alternative to formula when mother's own milk (MOM) is unavailable. The objective of this study was to evaluate the effects of a predominantly DBM diet on growth and subsequent neurodevelopment in preterm infants at a level 3 neonatal intensive care unit (NICU). METHODS: This single-center, observational cohort study compared data from preterm infants supplemented with predominantly (>50%) DBM to those from age- and weight-matched infants fed only MOM or supplemented with predominantly (>50%) preterm formula (PF)...

Cobalt (Co) and its compounds are widely distributed in nature and are part of numerous anthropogenic activities. Although cobalt has a biologically necessary role as metal constituent of vitamin B12, excessive exposure has been shown to induce various adverse health effects. This review provides an extended overview of the possible Co sources and related intake routes, the detection and quantification methods for Co intake and the interpretation thereof, and the reported health effects. The Co sources were allocated to four exposure settings: occupational, environmental, dietary and medical exposure...

Huntington disease is associated with elongation of a CAG repeat in the HTT gene that results in a mutant huntingtin protein. Several studies have implicated N-terminal huntingtin protein fragments in Huntington disease pathogenesis. Ideally, these fragments are studied in human brain tissue. However, the use of human brain tissue comes with certain unavoidable variables such as post mortem delay, artefacts from freeze-thaw cycles and subject-to-subject variation. Knowledge on how these variables might affect N-terminal huntingtin protein fragments in post mortem human brain is important for a proper interpretation of study results...

Hereditary cerebral hemorrhage with amyloidosis-Dutch type (HCHWA-D) is an early onset hereditary form of cerebral amyloid angiopathy (CAA) pathology, caused by the E22Q mutation in the amyloid β (Aβ) peptide. Transforming Growth Factor β1 (TGFβ1) is a key player in vascular fibrosis and in the formation of angiopathic vessels in transgenic mice. Therefore we investigated whether the TGFβ pathway is involved in HCHWA-D pathogenesis in human postmortem brain tissue from frontal and occipital lobes. Components of the TGFβ pathway were analyzed with quantitative RT-PCR...

Cardioprotective strategies to prevent damage to mitochondria in acute myocardial infarction are warranted to reduce lethal myocardial ischemia/reperfusion (I/R) injury. Mitochondrial antagonists in I/R are reactive oxygen species (ROS), deteriorated calcium signaling, permeabilization of the mitochondrial outer membrane (MOM) and deranged mitochondrial structural dynamism (fusion and fission). Nitric oxide (NO) related signaling can protect hearts from I/R. Albeit the underlying signaling is incompletely resolved, recent data point to a particular involvement of protective posttranslational modification of mitochondrial elements...
