Can stress biomarkers predict preterm birth in women with threatened preterm labor?

2017

Background: Preterm birth is a major paediatric challenge difficult to prevent and with major adverse outcomes. Prenatal stress plays an important role on preterm birth; however, there are few stress-related models to predict preterm birth in women with Threatened Preterm Labor (TPL). Objective: The aim of this work is to study the influence of stress biomarkers on time until birth in TPL women. Methods: Eligible participants were pregnant women between 24 and 31 gestational weeks admitted to the hospital with TPL diagnosis (n = 166). Stress-related biomarkers (a-amylase and cortisol) were determined in saliva samples after TPL diagnosis. Participants were followed-up until labor. A paramet…

Plasma cortisol levels in amyotrophic lateral sclerosis

Seabream (Sparus aurata) long-term dominant-subordinate interplay affects phagocytosis by peritoneal cavity cells.

2012

Fish are sensitive to stressful conditions that affect their innate immune systems and increase their susceptibility to diseases. We examined the social stress of paired gilthead seabream (Sparus aurata). Social hierarchies (dominant/subordinate) were characterised by behavioural changes, such as “aggressiveness” and “feeding order”; hierarchical positions were established within an hour of exposure to social stress and remained unchanged for approximately 1 year. To characterise physiological stress, we measured blood plasma levels of cortisol, glucose, and lactate as well as osmolarity and observed that the levels of these stress markers were higher in subordinate individuals than in domi…

Differential expression of two glucocorticoid receptors in seabass (teleost fish) head kidney after exogeneous cortisol inoculation

2009

Stressful conditions include a prompt release of corticosteroid hormones which can mediate gene expression through glucocorticoid receptors (GR). Since two seabass (Dicentrarchus labrax) GRs have been cloned and sequenced from peritoneal cavity cells (DlGR1) and liver (DlGR2), a comparative amino acid sequence analysis that included Haplochromis burtoni HbGRs, was carried out and homologies disclosed. The DlGR1 and DlGR2 deduced aminoacid sequences showed 61% identity (I) and 70% similarity (S). Moreover, DlGR2 was similar to HbGR2b (69% I, 73% S), and the DlGR1 to HbGR1 (72% I, 78% S). In addition, we examined the expression of the DlGRs after exogeneous cortisol inoculation into the perit…

Anxiety and depressive symptoms, and stress biomarkers in pregnant women after in vitro fertilization: a prospective cohort study.

2017

STUDY QUESTION Does in vitro fertilization (IVF) affect the course of anxiety and depressive symptoms as well as physiological stress from pregnancy to postpartum period? SUMMARY ANSWER IVF mothers have more anxiety symptoms and higher stress biomarker levels but fewer depression symptoms than natural conception mothers at the third trimester of pregnancy, but these differences are negligible during postpartum period. WHAT IS KNOWN ALREADY Cross-sectional studies have found an association between IVF and high stress levels during the prenatal period. There is, however, no follow-up study about the IVF effect on the mental health status from pregnancy to postpartum, adopting simultaneous mea…

Testosterone and cortisol responses to competitive fighting in human males: A pilot study

1987

Departamento de Psicologia Fisiologica (A.S., V.S., F.S.) and Laboratorio de MedicinaNuclear e Isotopos (L.L.), Hospital Clinico Universitario, Universitat de Valencia, Valencia,SpainSerum testosterone and cortisol levels were measured by radioimmunoassay in 14young male judo competitors, in samples taken 10 minutes before and 45 minutes aftertwo different pr(Redures. The first involved physical exercise and the second competi-tive fighting. Both procedures were of 5 minutes duration and sessions took plate atthe same time (between 10:00 \.M. and 12:00 P.M. liR-al lime) but on different days.Comparing the two situations over all subjects revealed that testosterone increasedafter exercise an…

Salivary characteristics may be associated with burning mouth syndrome?

2020

Background Burning mouth syndrome (BMS) it is characterized by burning and uncomfortable sensations with no clinical alterations or laboratory findings. The evaluation of the salivary characteristics of people with BMS can help the understanding of the pathogenesis of this condition. This case-control study aimed to trace the salivary profile of women with burning mouth syndrome (BMS). Material and Methods 40 women with BMS and 40 control women were recruited. Unstimulated salivary flow rate (uSFR), pH, salivary cortisol levels, salivary viscosity, and oral health impact profile (OHIP-14 questioner) were determined. P< 0.05 was considered statistically significant. Results For uSFR, mean va…

Post-encoding stress does not enhance memory consolidation: The role of cortisol and testosterone reactivity

2020

In contrast to the large body of research on the effects of stress-induced cortisol on memory consolidation in young people, far less attention has been devoted to understanding the effects of stress-induced testosterone on this memory phase. This study examined the psychobiological (i.e., anxiety, cortisol, and testosterone) response to the Maastricht Acute Stress Test and its impact on free recall and recognition for emotional and neutral material. Thirty-seven healthy young men and women were exposed to a stress (MAST) or control task post-encoding, and 24 h later, they had to recall the material previously learned. Results indicated that the MAST increased anxiety and cortisol levels, b…

Emotional intelligence modulates cortisol awakening response and self-reported health in caregivers of people with autism spectrum disorders

2014

Abstract Caring for people with autism spectrum disorders (ASDs) has negative consequences for caregivers’ health. Specifically, caregivers of people with ASDs have been observed to have more somatic symptoms, poorer self-perceived general health, poorer social functioning and altered immune and endocrine systems. Various positive variables including emotional intelligence (EI) have been found to protect health in several populations, but no studies have previously analyzed the effect of EI in caregivers of people with ASDs. The present study aimed to analyze the association of the three components of EI (attention, clarity and repair) with self-reported health and cortisol awakening respon…

A Mindfulness-Based Program Improves Health in Caregivers of People with Autism Spectrum Disorder: a Pilot Study

2014

Mindfulness-based interventions have demonstrated to be effective in reducing stress and health complaints in clinical populations. However, to our knowledge, biological health markers have not been used in studies of the effectiveness of mindfulness programs in caregivers of people with autism spectrum disorders (ASDs). This study aimed to assess the effects of a mindfulness intervention on mood disturbances and health complaints in this population compared with non-caregivers. The design of the study was quasi-experimental, with repeated measures. Self-reported health, cortisol awakening response (CAR), and afternoon cortisol levels before and after a mindfulness session were assessed at …
