Active ghrelin and the postpartum

Postpartum depression (PPD) occurs in 10%–15% of women. The appetite hormone ghrelin, which fluctuates during pregnancy, is associated with depression in nonpregnant samples. Here, we examine the association between PPD and active ghrelin from pregnancy to postpartum. We additionally examine whether ghrelin changes from pregnancy to postpartum and differs between breastfeeding and non-breastfeeding women

Estradiol variability, stressful life events, and the emergence of depressive symptomatology during the menopausal transition

To examine the role of estradiol fluctuation in triggering depressive symptoms in the menopause transition and assess the role of recent very stressful life events (VSLEs) as a moderating factor in this relationship

How is Post-Traumatic Stress Disorder in a Chronic Pelvic Pain Population Associated with Altered Surgical Outcome?

Background: The link between post-traumatic stress disorder (PTSD) and chronic pain conditions, specifically pelvic pain, has long been established. Within a chronic pelvic pain (CPP) population, the prevalence of PTSD is 31%, compared with 10% of women in the general population. In this group, the diagnosis of PTSD is usually associated with exposure to sexual and physical abuse. CPP is known to be a difficult diagnosis, in that many patients are refractory to treatment or suffer relapses. Meanwhile, PTSD alone is associated with overall poorer health outcomes. However, there is limited information on how pre-existing PTSD affects CPP in regards to treatment outcomes and disease trajectory. Objective: To determine if a diagnosis of PTSD is associated with differences in long-term pain outcomes among a CPP population treated with surgery

Histories of abuse predict stronger within-person covariation of ovarian steroids and mood symptoms in women with menstrually related mood disorder

Individual differences in sensitivity to cyclical changes in ovarian steroids estradiol (E2) and progesterone (P4) have been implicated in the pathophysiology of menstrually related mood disorder (MRMD). However, no prospective studies have investigated psychosocial risk factors for sensitivity to hormone effects on mood in MRMD. Using a repeated measures approach and multilevel models, we tested the hypothesis that a history of abuse provides a context in which within-person elevations of E2 and P4 prospectively predict daily symptoms

The influence of early life sexual abuse on oxytocin concentrations and premenstrual symptomatology in women with a menstrually related mood disorder

Oxytocin (OT), associated with affiliation and social bonding, social salience, and stress/pain regulation, may play a role in the pathophysiology of stress-related disorders, including menstrually-related mood disorders (MRMD's). Adverse impacts of early life sexual abuse (ESA) on adult attachment, affective regulation, and pain sensitivity suggest ESA-related OT dysregulation in MRMD pathophysiology. We investigated the influence of ESA on plasma OT, and the relationship of OT to the clinical phenomenology of MRMD's. Compared to MRMD women without ESA (n=40), those with ESA (n=20) displayed significantly greater OT [5.39 pg/mL (SD, 2.4) vs. 4.36 pg/mL (SD, 1.1); t (58) = −2.26, p =.03]. In women with ESA, OT was significantly, inversely correlated with premenstrual psychological and somatic symptoms (r's = −.45 to −.64, p's < .05). The relationship between OT and premenstrual symptomatology was uniformly low and non-significant in women without ESA. In women with ESA, OT may positively modulate MRMD symptomatology

Catastrophizing: a predictor of persistent pain among women with endometriosis at 1 year

Endometriosis is the most common gynecological diagnosis among women with chronic pelvic pain, but the underlying mechanisms of endometriosis-associated chronic pelvic pain remain unclear. Therefore, the objective of this study was to determine the biopsychosocial predictors of pain improvement among women with endometriosis

Alterations of brain activity associated with resolution of emotional distress and pain in a case of severe irritable bowel syndrome

: The association of psychosocial disturbances with more severe irritable bowel syndrome (IBS) is well recognized. However, there is no evidence as to how these associations might be mediated. Functional magnetic resonance imaging (fMRI) offers an opportunity to study whether activation of the cingulate cortex, an area involved with the affective and pain intensity coding might be linked to poorer clinical status with IBS. In this case report, we found an association between the severity of a patient's clinical symptoms and psychosocial state, with activation of the cingulate cortex. We also found that clinical and psychosocial improvement was associated with reduced cingulate activation. : Observational case report of a young woman observed for 16 years with a history of sexual abuse, psychosocial distress, and functional GI complaints. Psychosocial, clinical, and fMRI assessment was performed when the patient experienced severe symptoms and again 8 months later when clinically improved. : During severe illness, the patient had major psychosocial impairment, high life stress, a low visceral pain threshold, and activation of the midcingulate cortex (MCC), prefrontal area 6/44, and the somatosensory cortex, areas associated with pain intensity encoding. When clinically improved, there was resolution in activation of these 3 areas, and this was associated with psychosocial improvement and an increased threshold to rectal distention. : Activation of the MCC and related areas involved with visceral pain encoding are associated with poor clinical status in patients with severe IBS and psychosocial distress and appear to be responsive to clinical improvement.GASTROENTEROLOGY 2003;124:754-76

Persistent alterations in biological profiles in women with abuse histories: Influence of premenstrual dysphoric disorder.

To examine dysregulation in biological measures associated with histories of abuse in women and whether women with premenstrual dysphoric disorder (PMDD) differ in their dysregulation

Measuring the effect of intimate partner violence on health-related quality of life: a qualitative focus group study

Abstract Background Health related quality of life (HRQOL) can be measured by a wide range of instruments, many of which have been designed for specific conditions or uses. Preference-based measures assess the value individuals place on health, and are included in economic evaluations of treatments and interventions (such as cost effectiveness analysis). As economic evaluation becomes more common, it is important to assess the applicability of preference-based health related quality of life (HRQOL) measures to public health issues. This study investigated the usefulness of such instruments in the context of intimate partner violence (IPV), a public health concern that that can seriously affect quality of life. Methods The study consisted of focus groups with abused women to determine the aspects of life affected by IPV, and an analysis of existing HRQOL measures. Eight focus groups (n = 40) were conducted in which participants discussed the domains of health affected by IPV. Results were content analyzed and compared with the domains of health included in four commonly-used, preference-based HRQOL measures. Results The average focus group participant was 43 years old, unemployed, African American, with 3 children. Domains of health reported to be affected by IPV included physical functioning, emotional and psychological functioning, social functioning and children\u27s functioning. Psychological health was the most severely affected domain. The Short Form 36, the Health Utilities Index, the EuroQol 5D, and the Quality of Well-being Scale were found to vary in the degree to which they include domains of health important in IPV. Psychological health is included to a limited extent, and the spill-over effect of a condition on other family members, including children, is not included at all. Conclusion Emotional and psychological health plays an important role in the overall HRQOL of abused women but is relatively underemphasized in preference-based HRQOL measures. This may lead to an underestimation of the impact of partner violence on HRQOL when using these measures and in economic evaluations that rely thereon. Holistic measurement approaches or expanded measures that capture the far-reaching effects of IPV on HRQOL may be needed to accurately measure the effect of this condition on women\u27s health

Effect of Abuse History on Pain Reports and Brain Responses to Aversive Visceral Stimulation: An fMRI Study

Abuse history is common in irritable bowel syndrome (IBS) and is associated with greater pain reporting, psychologic distress, and poorer health outcome. These effects may be mediated by enhanced responses to aversive visceral stimuli. We investigated the effects of IBS and abuse history on pain reporting and brain activation in response to rectal distentions. Ten female patients with IBS and 10 controls were included. Half of patients in each group reported a history of abuse. Brain functional magnetic resonance imaging (fMRI) images and pain ratings were obtained during rectal distentions. Statistical parametric mapping identified activation in subregions of the dorsal cingulate cortex and covariation with rated pain. (1) Distention-elicited pain correlated with anxiety and activation of the posterior (PCC) and middle (MCC) dorsal cingulate subregions. (2) Subjects with a history of abuse showed greater activation in the left MCC ( = .022; t = 5.61) and PCC ( = .033; t = 5.00) than subjects without abuse. (3) Those with IBS and abuse reported greater pain than all others ( = .004), had more activity in the left MCC ( = .021; t = 5.29) and PCC ( = .049; t = 4.81), and had less activity in the left supragenual anterior cingulate (sACC) ( = .01; t = 4.86). Pain ratings during rectal distention are associated with activation of dorsal cingulate regions implicated in homeostatic afferent processing, and prior abuse enhances this activation. Patients with IBS and abuse report more pain, greater MCC/PCC activation, and reduced activity of a region implicated in pain inhibition and arousal (sACC). These findings suggest a possible explanation for the clinical observation of greater pain reporting and poorer outcome in IBS patients with a history of abuse
