nonstress test

Jianyang Lu, Hongbo Zhai
RATIONALE: Primary intestinal lymphangiectasia (PIL) is a rare disease characterized by dilated intestinal lacteals resulting in lymph leakage into the small bowel lumen. Main clinical features include intermittent diarrhea, hypoproteinemia. Scattered case reports suggested that PIL is compatible to pregnancy, but with increased complications. PATIENT CONCERNS: A 34-year-old woman with endoscopically diagnosed PIL presented to antenatal our clinic at 10 weeks into gestation...

CONTEXT: One of the main goals of antenatal testing is to identify fetuses at the risk of neurologic injury or death so that these adverse outcomes can be prevented. We want to assess the effects of BL67 points' stimulation on fetal heart rate parameters and fetal movements during nonstress test (NST). We did a quasi-experimental design in Shahid Beheshti Hospital in Isfahan in 2011. AIMS: This study aims to assessment of the effects of BL67 points' stimulation on fetal heart rate parameters and fetal movements...

We describe a patient with Class C diabetes who presented for nonstress testing at 36 weeks and 4 days of gestation with nonreassuring fetal heart tones (NRFHT) and oligohydramnios. Upon delivery, thrombosis of the umbilical cord was grossly noted. Pathological analysis of the placenta revealed chorangiosis, vascular congestion, and 40% occlusion of the umbilical vein. Chorangiosis is a vascular change of the placenta that involves the terminal chorionic villi. It has been proposed to result from longstanding, low-grade hypoxia in the placental tissue and has been associated with such conditions such as diabetes, intrauterine growth restriction (IUGR), and hypertensive conditions in pregnancy...

BACKGROUND: Vagal reactivity to stress in children has been associated with future psychiatric outcomes. However, results have been mixed possibly because these effects are in opposite direction in boys and girls. These sex differences are relevant in the context of development of psychopathology, whereby the rates of psychiatric disorders differ by sex. In this study, we aimed to examine the association between vagal reactivity, assessed as a reduction in respiratory sinus arrhythmia (RSA) in response to a challenge, and the development of future oppositional defiant disorder (ODD) symptoms in boys and girls...

Following gut epithelial damage, epidermal growth factor receptor/mitogen-activated protein kinase (EGFR/MAPK) signalling triggers Drosophila intestinal stem cells to produce enteroblasts (EBs) and enterocytes (ECs) that regenerate the gut. As EBs differentiate into ECs, they become postmitotic, but undergo extensive growth and DNA endoreplication. Here we report that EGFR/RAS/MAPK signalling is required and sufficient to drive damage-induced EB/EC growth. Endoreplication occurs exclusively in EBs and newborn ECs that inherit EGFR and active MAPK from fast-dividing progenitors...

Characteristics of depressive-like behavior of male rats with androgen deficiency born by mothers subjected to prenatal stress during pregnancy were assessed by using Porsolt tests and open-field tests. The level of depression-like behavior in prenatally stressed males increased more intensively than in non-stressed gonadectomized males. Chronic administration of testosterone propionate (0.5 mg/kg, intramuscularly, for 14 days) increased depressive behavior in prenatally stressed gonadectomized males in contrast to its antidepressant effect in nonstressed gonadectomized rats...

The development of animal models with construct, face, and predictive validity to accurately model human depression has been a major challenge. One proposed rodent model is the 5 d repeated forced swim stress (5d-RFSS) paradigm, which progressively increases floating during individual swim sessions. The onset and persistence of this floating behavior has been anthropomorphically characterized as a measure of depression. This interpretation has been under debate because a progressive increase in floating over time may reflect an adaptive learned behavioral response promoting survival, and not depression (Molendijk and de Kloet, 2015)...

BACKGROUND: Nonclinical studies indicate that the hormone relaxin is a good candidate for a safe cervical ripening agent that does not cause uterine contractions. METHODS: This Phase II study (conducted November 2, 2005-October 20, 2006) was a randomised, double blind, placebo controlled trial testing 24-h intravenous infusion of serelaxin (recombinant human relaxin) or placebo for cervical ripening in 72 healthy, primiparous women. Eligible subjects had a singleton pregnancy ≥40 weeks, were planned for elective induction, had vertex presentation of the fetus, intact membranes and a Bishop score at screening ≤4...

Background. Primary hyperparathyroidism is rare in pregnancy. An association between primary hyperparathyroidism and preeclampsia has been reported in few cases worldwide. Case. A 28-year-old woman (gravida 2, para 0, and abortus 1) in her 27th week of gestation was hospitalized due to a high reading of blood pressure (194/115 mmHg) that was not accompanied by any symptoms or signs of preeclampsia. Incidentally, she was found to have a high adjusted calcium and serum parathyroid hormone (PTH) level during admission...

Accumulating evidence supports a role of T cells in behavioral stress responsiveness. Our laboratory previously reported that lymphocyte deficient Rag2(-/-) mice on a BALB/c background display resilience to maladaptive stress responses when compared with immune competent mice in the predator odor exposure (POE) paradigm, while exhibiting similar behavior in a cued fear-conditioning (FC) paradigm. In the present study, Rag2(-/-) mice on a C57BL/6 background were assessed in the same behavioral paradigms, as well as additional tests of anxiety and depressive-like behavior...

INTRODUCTION: It is estimated that 3-10% of infants are growth restricted. Growth disturbances may have long-term issues. Doppler allows insight into the fetal response to intrauterine stress. OBJECTIVE: The aim of this study was to detect fetal compromise in intrauterine growth-restricted (IUGR) fetuses by means of biophysical profile (BPP) vis-à-vis Doppler velocimetry studies of the fetal umbilical artery, and to find out which of the two is a better and earlier predictor of fetal compromise...

BACKGROUND: Major depression is one of the most prevalent psychiatry comorbidities of alcohol use disorders (AUD). As negative emotions can trigger craving and increase the risk of relapse, treatments that target both conditions simultaneously may augment treatment success. Previous studies showed a potential synergistic effect of Food and Drug Administration approved medication for AUD acamprosate and the antidepressant escitalopram. In this study, we investigated the effects of combining acamprosate and escitalopram on ethanol (EtOH) consumption in stress-induced depressed mice...

Ageing and stress exposure may lead to memory impairment while oxidative stress is thought to be one of the underlying mechanisms involved. This study aimed to investigate the potential protective effects of Tualang honey supplementation on memory performance in aged rats exposed to noise stress. Tualang honey supplementation was given orally, 200 mg/kg body weight for 28 days. Rats in the stress group were subjected to loud noise, 100 dB(A), 4 hours daily for 14 days. All rats were subjected to novel object recognition test for evaluation of memory performance...

We previously observed lasting and sex-specific detrimental consequences of early adolescent intermittent ethanol exposure (AIE), with male, but not female, rats showing social anxiety-like alterations when tested as adults. The present study used Sprague Dawley rats to assess whether social alterations induced by AIE (3.5g/kg, intragastrically, every other day, between postnatal days [P] 25-45) are further exacerbated by stressors later in life. Another aim was to determine whether AIE alone or in combination with stress influenced intake of a sweetened ethanol solution (Experiment 1) or a sweetened solution ("supersac") alone (Experiment 2) under social circumstances...

BACKGROUND: Altered levels of urocortin 1 (Ucn1) in the centrally projecting Edinger-Westphal nucleus (EWcp) of depressed suicide attempters or completers mediate the brain's response to stress, while the mechanism regulating Ucn1 expression is unknown. We tested the hypothesis that microRNAs (miRNAs), which are vital fine-tuners of gene expression during the brain's response to stress, have the capacity to modulate Ucn1 expression. METHODS: Computational analysis revealed that the Ucn1 3' untranslated region contained a conserved binding site for miR-326...

INTRODUCTION: We describe experience with an unexpectedly high background incidence of atrioventricular block (AVB) observed in Mauritian cynomolgus monkeys (MCM) during preclinical safety assessment for bitopertin, a glycine-transporter-1 inhibitor. METHODS: Preclinical ECGs were reviewed to assess potential effects on cardiac conductivity, specifically AVB. RESULTS: Bitopertin administration in Chinese/Vietnamese monkeys (CVM; n=46) or MCM (n=64, from all relevant studies) revealed dose-dependent hypoactivity with a lack of expected increases in heart rate in response to chair-restraint during ECG recordings...
