The Unexpected Benefits of a Decolonized Knowledge Translation Initiative for Indigenous Mother Participants.

Western health research's approach to knowledge translation (KT) has been criticized by Indigenous scholars, leaders, and communities for its misalignment with Indigenous ways of knowing and relational approaches to sharing knowledge. Conversely, Indigenous KT is understood as 'sharing what we know about living a good life' (Kaplan-Myrth & Smylie, 2006). Whereas KT in Euro-Western science contexts focuses on closing the know-do gap implying a separation of knowledge and action, knowledge in the Indigenous context is inherently practical and based on centuries old practices including oral traditions, experiential knowledge, and cross-cultural sharing. This article describes the development of a decolonized KT strategy. This community-engaged KT initiative was developed at the suggestion of Indigenous mothers who participated in a research study in Hamilton, Canada, which examined their experiences using health care to meet the health needs of their infants. Indigenous mothers participated in three main roles related to the KT activities: sharing their story in video, participating as team members on an Advisory Board, and directing the creation of a video series and website educational resource (KT strategy). Five Indigenous mothers participated as members of the Advisory Board. The process of participating had positive impacts on the mothers, namely, empowerment, strength, 'I am not alone', and healing. These unexpected findings, which go beyond the original project purpose to create an educational resource, show the significant and important benefits for research participants, particularly those from Indigenous communities, to be involved in decolonized KT strategies.

Predictors of weight loss after bariatric surgery-a cross-disciplinary approach combining physiological, social, and psychological measures.

BACKGROUND: Bariatric surgery leads to a substantial weight loss (WL), however, a subset of patients undergoing surgery fails to achieve adequate WL. The reason for the individual variation in WL remains unexplained. Using an exploratory cross-disciplinary approach, we aimed to identify preoperative and early postoperative factors explaining the variation in WL after bariatric surgery. METHODS: Sixty-one subjects were recruited. Eighteen subjects did not receive surgery and three subjects dropped out, leaving a total sample of 40 subjects. Physiological, social, and psychological data were collected before and 6 months after surgery. All variables were analyzed in combination using a least absolute shrinkage and selection operator (LASSO) regression to explain the variation in WL 18 months after Roux-en-Y gastric bypass (n = 30) and sleeve gastrectomy (n = 10). RESULTS: Mean WL was 31% (range: 10-52%). The following preoperative factors predicted 59% of the variation in WL: type of surgery (14%), diabetes status (12%), economic resources (9%), sex (7%), binge eating disorder (7%), degree of depression (5%), household type (3%), and physical activity (1%). Including information on early responses after surgery increased the ability to predict WL to 78% and was explained by early WL (47%), changes in energy density of food consumed from a buffet meal (9%), changes in glicentin (5%), degree of depression (5%), sex (5%), type of surgery (2%), economic resources (2%), and changes in drive for thinness (1%). CONCLUSIONS: Using a cross-disciplinary approach, a substantial part of the individual variation in WL was explained by a combination of basic patient characteristics, psychological profile, and social conditions as well as physiological, psychological and behavioral responses to surgery. These results suggest that patient characteristics collected in a cross-disciplinary approach may help determine predictors for less successful WL after bariatric surgery. If verified in larger cohorts this may form the basis for individualized postoperative support to optimize WL outcome.

Compression of the superior mesenteric vein-a sign of acute internal herniation in patients with antecolic laparoscopic Roux-en-Y gastric bypass.

OBJECTIVES: To investigate whether compression of the superior mesenteric vein (SMV) on computed tomography (CT) can serve as a valid sign of internal herniation (IH) in patients with antecolic laparoscopic Roux-en-Y gastric bypass (LRYGBP). MATERIALS AND METHODS: With institutional review board approval, we performed a retrospective analysis of 41 patients with antecolic LRYGBP referred for acute CT of the abdomen with suspicion of IH or another cause of acute abdomen. CT scans were randomly reviewed for signs of IH by two radiologists in a blinded manner, and the findings were correlated with the results of the patients' bariatric workup. Sensitivity, specificity, and inter-observer agreement were calculated for each sign. RESULTS: Five patients were classified as having intermittent IH and were excluded. Eighteen patients were found to have IH at laparoscopy and served as the study group; 18 patients served as the control group. SMV compression had the best sensitivity (67 % for both reviewers) and inter-observer agreement (kappa = 0.82) of all investigated signs. The swirl sign showed a lower sensitivity (39 and 50 % respectively) and kappa (0.37). CONCLUSION: SMV compression is a reliable sign of IH in patients with antecolic LRYGBP. KEY POINTS: • CT can help detect internal herniation after laparoscopic Roux-en-Y gastric bypass. • Compression of the superior mesenteric vein is a sign of internal herniation. • This sign has a high inter-observer-agreement. • A diagnosis of internal herniation can be made with greater confidence.

Early 24-hour blood pressure response to Roux-en-Y gastric bypass in obese patients.

Recently, it has been proposed, that the blood pressure (BP) lowering effect of gastric bypass surgery not only is explained by the obtained weight loss, but that the anatomical rearrangement of the gut after 'malabsorptive' surgical techniques, such as the laparoscopic Roux-en-Y gastric bypass (LRYGB), may affect BP through a change in a putative 'entero-renal' axis. If so one could anticipate a reduction in BP even before a noticeable weight loss was obtained. The purpose of the present study was to investigate the very early BP response to LRYGB surgery. Ten severely obese hypertensive (mean BMI 40.8 kg/m2) and 10 severely obese normotensive (mean BMI 41.7 kg/m2) patients underwent 24-h ambulatory blood pressure measurements (24 h ABPMs) before LRYGB and again day 1 and day 10 after LRYGB. No change in 24 h BP was observed day 1 after LRYGB. Day 10 after surgery both hypertensive and normotensive patients demonstrated a significant 12.6 mmHg and 9.5 reduction in systolic BP (SBP), respectively. Mean arterial pressure (MAP) decreased by 8.3 and 5.4 mmHg. At day 10 postoperatively, a weight loss of 7.9 kg in the hypertensive patients and 7.0 kg in the normotensive patients was observed. The reduction in BP after LRYGB takes place before any substantial weight loss has occurred. The reason for this remains speculative, but obese hypertensive patients may clearly benefit from the operation even if the goal of achieving 'normoweight' is not obtained.

Hepatic mitochondrial oxidative phosphorylation is normal in obese patients with and without type 2 diabetes.

KEY POINTS: Hepatic insulin resistance in patients with obesity or type 2 diabetes has been suggested to result from hepatic mitochondrial dysfunction. High-resolution respirometry (HRR) can be used to assess oxidative phosphorylation by measuring the mitochondrial oxygen consumption rate in the individual complexes of the mitochondria. By using HRR, the present study demonstrates no difference in hepatic mitochondrial oxidative phosphorylation among subjects with obesity with or without type 2 diabetes and non-obese controls. Furthermore, the amount of mitochondria, assessed by the citrate synthase activity, is not different between the three groups. Together the present findings indicate that hepatic mitochondrial oxidative phosphorylation capacity is not impaired in patients with obesity or type 2 diabetes. ABSTRACT: Obese patients with type 2 diabetes (T2DM) and without type 2 diabetes (OB) are characterized by high hepatic lipid content and hepatic insulin resistance. This may be linked to impaired hepatic mitochondrial oxidative phosphorylation (OXPHOS) capacity. The aim of the present study was to investigate and compare hepatic mitochondrial OXPHOS capacity in T2DM, OB and non-obese controls (CON). Seventeen obese patients (nine OB and eight T2DM) and six CON patients had perioperative liver biopsies taken. Samples were divided into three parts to measure (1) complex I, II and IV linked respiration, (2) citrate synthase (CS) activity and (3) lipid droplet (LD) size and area (% of total tissue area filled by LDs). State 3 respiration of complex I, II and IV and the CS activity did not differ in OB, T2DM and CON. LD size was significantly higher in T2DM compared with CON, and LD area tended (P = 0.10) to be higher in T2DM and OB compared with CON. The present findings indicate that hepatic OXPHOS capacity is not different in patients with markedly different weight and glycaemic control. Furthermore, the results do not support impaired hepatic mitochondrial respiratory capacity playing a major role in the development of obesity-induced type 2 diabetes.

Preoperative ß-cell function in patients with type 2 diabetes is important for the outcome of Roux-en-Y gastric bypass surgery.

The majority of the patients with type 2 diabetes (T2DM) show remission after Roux-en-Y gastric bypass (RYGB). This is the result of increased postoperative insulin sensitivity and ß-cell secretion. The aim of the present study was to elucidate the importance of the preoperative ß-cell function in T2DM for the chance of remission after RYGB. Fifteen patients with and 18 without T2DM had 25 g oral (OGTT) and intravenous (IVGTT) glucose tolerance tests performed at inclusion, after a diet-induced weight loss, and 4 and 18 months after RYGB. Postoperative first phase insulin secretion rate (ISR) during the IVGTT and ß-cell glucose sensitivity during the OGTT increased in T2DM. Postoperative insulin sensitivity and the disposition index (DI) markedly increased in both groups. By stratifying the T2DM into two groups according to highest (T2DMhigh ) and lowest (T2DMlow ) baseline DI, a restoration of first phase ISR and ß-cell glucose sensitivity were seen only in T2DMhigh . Remission of type 2 diabetes was 71 and 38% in T2DMhigh and T2DMlow , respectively. Postoperative postprandial GLP-1 concentrations increased markedly, but did not differ between the groups. Our findings emphasize the importance of the preoperative of ß-cell function for remission of diabetes after RYGB.

Mindfulness meditation alleviates fibromyalgia symptoms in women: results of a randomized clinical trial.

BACKGROUND: Several recent reviews have evaluated evidence on the efficacy of Mindfulness-Based Stress Reduction (MBSR) among fibromyalgia sufferers, and concluded that more research should test effects on both psychological and physiological functioning. PURPOSE: We conducted a randomized prospective trial of MBSR among female fibromyalgia patients. METHODS: Effects on perceived stress, pain, sleep quality, fatigue, symptom severity, and salivary cortisol were tested in treatment (n=51) versus wait-list control participants (n=40) using data at baseline, post-program, and 2-month follow-up. RESULTS: Analyses revealed that MBSR significantly reduced perceived stress, sleep disturbance, and symptom severity, with gains maintained at follow-up. Greater home practice at follow-up was associated with reduced symptom severity. MBSR did not significantly alter pain, physical functioning, or cortisol profiles. CONCLUSION: MBSR ameliorated some of the major symptoms of fibromyalgia and reduced subjective illness burden. Further exploration of MBSR effects on physiological stress responses is warranted. These results support use of MBSR as a complementary treatment for women with fibromyalgia ( ISRCTN: 34628811).

Diurnal cortisol rhythm as a predictor of lung cancer survival.

BACKGROUND: Poorly coordinated diurnal cortisol and circadian rest-activity rhythms predict earlier mortality in metastatic breast and colorectal cancer, respectively. We examined the prognostic value of the diurnal cortisol rhythm in lung cancer. METHODS: Lung cancer patients (n=62, 34 female) were within 5 years of diagnosis and had primarily non small-cell lung cancer, with disease stage ranging from early to advanced. Saliva collected over two days allowed calculation of the diurnal cortisol slope and the cortisol awakening response (CAR). Lymphocyte numbers and subsets were measured by flow cytometry. Survival data were obtained for 57 patients. Cox Proportional Hazards analyses were used to test the prognostic value of the diurnal cortisol rhythm on survival calculated both from study entry and from initial diagnosis. RESULTS: The diurnal cortisol slope predicted subsequent survival over three years. Early mortality occurred among patients with higher slopes, or relatively "flat" rhythms indicating lack of normal diurnal variation (Cox Proportional Hazards p=.009). Cortisol slope also predicted survival time from initial diagnosis (p=.012). Flattened profiles were linked with male gender (t=2.04, df=59, p=.046) and low total and cytotoxic T cell lymphocyte counts (r=-.39 and -.30, p=.004 and .035, respectively). After adjustment for possible confounding factors, diurnal slope remained a significant, independent predictor of survival. CONCLUSIONS: Flattening of the diurnal cortisol rhythm predicts early lung cancer death. Data contribute to growing evidence that circadian disruption accelerates tumor progression.

Perceived health in lung cancer patients: the role of positive and negative affect.

PURPOSE: To examine the association of affective experience and health-related quality of life in lung cancer patients, we hypothesized that negative affect would be positively, and positive affect would be negatively, associated with perceived health. METHODS: A sample of 133 English-speaking lung cancer patients (33% female; mean age = 63.68 years old, SD = 9.37) completed a battery of self-report surveys. RESULTS: Results of our secondary analysis indicate that trait negative affect was significantly associated with poor physical and social functioning, greater role limitations due to emotional problems, greater bodily pain, and poor general health. Positive affect was significantly associated with adaptive social functioning, fewer emotion-based role limitations, and less severe bodily pain. In a full model, positive affect was significantly associated with greater levels of social functioning and general health, over and above the effects of negative affect. CONCLUSIONS: Reduction of negative affect is an important therapeutic goal, but the ability to maintain positive affect may result in greater perceived health. Indeed, engagement in behaviors that result in greater state positive affect may, over time, result in dispositional changes and enhancement of quality of life.

Receipt of a false positive test result during routine screening for ovarian cancer: a teachable moment?

The term "teachable moment" (TM) has been used to describe a life transition or event which motivates an individual to change a behavior or presents an opportunity to intervene to prompt behavior change. We examined whether receipt of a false positive ovarian cancer (OC) screening result may represent a TM. 403 women participating in an OC screening program completed questionnaires assessing demographic, clinical, behavioral, and psychosocial information. The TM was operationalized as expressed interest in receiving health-related information. We hypothesized that among women receiving a false positive screening test result, those women who had experienced greater personal perceived risk for OC as well as distress would be more interested in receiving health-related information than women receiving a normal result. Analyses revealed that women receiving a false positive screening result were less interested in receiving health-related information than women receiving a normal screening result. For women receiving a false positive result, expressed interest in receipt of health-related information was only modestly related to distress and related even less to perceptions of OC risk. Our data do not support viewing a false positive OC screening result as a TM. Potential explanations for the current findings as well as recommendations for future research investigating the TM are discussed.

Gut Mucosal Gene Expression and Metabolic Changes After Roux-en-Y Gastric Bypass Surgery.

OBJECTIVE: Changes in the secretion of gut-derived peptide hormones have been associated with the metabolic benefits of Roux-en-Y gastric bypass (RYGB) surgery. In this study, the effects of RYGB on anthropometrics, postprandial plasma hormone responses, and mRNA expression in small intestinal mucosa biopsy specimens before and after RYGB were evaluated. METHODS: In a cross-sectional study, 20 individuals with obesity undergoing RYGB underwent mixed meal tests and upper enteroscopy with retrieval of small intestinal mucosa biopsy specimens 3 months before and after surgery. Concentrations of circulating gut and pancreatic hormones during mixed meal tests as well as full mRNA sequencing of biopsy specimens were evaluated. RESULTS: RYGB-induced improvements of body weight and composition, insulin resistance, and circulating cholesterols were accompanied by significant changes in postprandial plasma responses of pancreatic and gut hormones. Global gene expression analysis of biopsy specimens identified 2,437 differentially expressed genes after RYGB, including changes in genes that encode prohormones and G protein-coupled receptors. CONCLUSIONS: RYGB affects the transcription of a wide range of genes, indicating that the observed beneficial metabolic effects of RYGB may rely on a changed expression of several genes in the gut. RYGB-induced changes in the expression of genes encoding signaling peptides and G protein-coupled receptors may disclose new gut-derived treatment targets against obesity and diabetes.

Mindfulness meditation for symptom reduction in fibromyalgia: psychophysiological correlates.

OBJECTIVES: Fibromyalgia, a chronic pain syndrome, is often accompanied by psychological distress and increased basal sympathetic tone. In a previous report it was shown that mindfulness-based stress-reduction (MBSR) reduced depressive symptoms in patients with fibromyalgia with gains maintained at two months follow-up (Sephton et al., Arthr Rheum 57:77-85, 2007). This second study explores the effects of MBSR on basal sympathetic (SNS) activation among women with fibromyalgia. METHODS: Participants (n = 24) responded to a television news appearance, newspaper, and radio advertisements. Effects on anxiety, depressive symptoms, and SNS activation measures were tested before and after MBSR using a within-subjects design. RESULTS: The MBSR treatment significantly reduced basal electrodermal (skin conductance level; SCL) activity (t = 3.298, p = .005) and SCL activity during meditation (t = 4.389, p = .001), consistent with reduced SNS activation. CONCLUSIONS: In this small sample, basal SNS activity was reduced following MBSR treatment. Future studies should assess how MBSR may help reduce negative psychological symptoms and attenuate SNS activation in fibromyalgia. Further clarification of psychological and physiological responses associated with fibromyalgia may lead to more beneficial treatment.

Theories underlying health promotion interventions among cancer survivors.

OBJECTIVES: To review the theories that have been the basis for randomized controlled trials (RCTs) promoting health behavior change among adults diagnosed and treated for cancer. DATA SOURCES: Electronic databases and recent review papers. CONCLUSION: Several theories have been used in intervention development: Transtheoretical Model, Motivational Interviewing, Social Learning and Social Cognitive Theory, Theory of Planned Behavior, and Cognitive Behavioral Theory. There is support for the efficacy of some of these interventions. However, there has been limited assessment of theory-based constructs and examination of the mediational role of theoretical constructs in intervention efficacy. IMPLICATIONS FOR NURSING PRACTICE: There is a need to apply theory in the development of interventions to assess the effects of the intervention on the constructs and to conduct mediational tests of these constructs.

Psychological health in cancer survivors.

OBJECTIVES: The prevalence of both negative (distress) and positive responses (growth, well-being) to the cancer experience is examined and difficulties in establishing the prevalence of these responses discussed. A conceptual framework for understanding factors associated with psychological health in cancer survivors is presented. Finally, strategies for promoting psychological health in cancer survivors are examined. DATA SOURCES: Review of the literature. CONCLUSION: Psychological health in cancer survivors is defined by the presence or absence of distress as well as the presence or absence of positive well-being and psychological growth. Furthermore, psychological health in cancer survivors is determined by the balance between two classes of factors: the stress and burden posed by the cancer experience and the resources available for coping with this stress and burden. IMPLICATIONS FOR NURSING PRACTICE: In general, promotion of psychological health is based on the prevention or treatment of distress as well as the encouragement of growth and well-being. Periodic screening for psychological distress across the cancer trajectory is critical to appropriate management of distress.

Patient profiling for success after weight loss surgery (GO Bypass study): An interdisciplinary study protocol.

Despite substantial research efforts, the mechanisms proposed to explain weight loss after gastric bypass (RYGB) and sleeve gastrectomy (SL) do not explain the large individual variation seen after these treatments. A complex set of factors are involved in the onset and development of obesity and these may also be relevant for the understanding of why success with treatments vary considerably between individuals. This calls for explanatory models that take into account not only biological determinants but also behavioral, affective and contextual factors. In this prospective study, we recruited 47 women and 8 men, aged 25-56 years old, with a BMI of 45.8 ±â€¯7.1 kg/m2 from the waiting list for RYGB and SL at Køge hospital, Denmark. Pre-surgery and 1.5, 6 and 18 months after surgery we assessed various endpoints spanning multiple domains. Endpoints were selected on basis of previous studies and include: physiological measures: anthropometrics, vital signs, biochemical measures and appetite hormones, genetics, gut microbiota, appetite sensation, food and taste preferences, neural sensitivity, sensory perception and movement behaviors; psychological measures: general psychiatric symptom-load, depression, eating disorders, ADHD, personality disorder, impulsivity, emotion regulation, attachment pattern, general self-efficacy, alexithymia, internalization of weight bias, addiction, quality of life and trauma; and sociological and anthropological measures: sociodemographic measures, eating behavior, weight control practices and psycho-social factors.Joining these many endpoints and methodologies from different scientific disciplines and creating a multi-dimensional predictive model has not previously been attempted. Data on the primary endpoint are expected to be published in 2018. TRIAL REGISTRATION: Clinicaltrials. gov ID NCT02070081.

Methodologic issues in exercise intervention research in oncology.

OBJECTIVES: To review randomized controlled trials that offered exercise interventions for adults diagnosed and treated for cancer related to design, sample, type of intervention, and outcomes. DATA SOURCES: Several electronic databases were searched and recent review papers were scanned to identify relevant publications. CONCLUSION: Exercise adoption seems clearly feasible for early stage cancer patients, particularly breast cancer patients. Data support positive effects for physical functioning, quality of life, and psychological well-being. Effects for patients with later-stage disease and other cancers are less clear. The impact of exercise adoption on biomarkers of disease status, immune functioning, and hormone levels should also be examined. IMPLICATIONS FOR NURSING PRACTICE: There are many opportunities for nurses to promote exercise in clinical care and in a research context.

Treatment of Common Bile Duct Stones in Gastric Bypass Patients with Laparoscopic Transgastric Endoscopic Retrograde Cholangiopancreatography.

BACKGROUND: Laparoscopic Roux-en-Y gastric bypass excludes the biliary tree from traditional evaluation and treatment with endoscopic retrograde cholangiopancreatography (ERCP). Due to the initial rapid weight loss, gastric bypass patients have an increased risk of developing gallstones in the gallbladder as well as in the common bile duct. Various techniques to access the biliary tree have been described. The techniques are characterised by complexity and varying results. The aim of the present study was to assess both feasibility and outcome of laparoscopic-assisted transgastric ERCP in patients with gastric bypass. METHODS: We retrospectively reviewed all laparoscopic transgastric ERCPs performed at Zealand University Hospital during the period January 2010 to January 2016. The main outcome was cannulation of the common bile duct. Secondary outcomes were length of hospital stay and surgical complications. RESULTS: Thirty-one laparoscopic assisted transgastric ERCP procedures were performed in 29 patients. Indication was choledocholithiasis. All planned procedures were conducted with a 100% success in cannulation of the common bile duct. Median hospital stay was 2 days (range 1-22). Perforation of the wall of the gastric remnant occurred in two patients. The overall postoperative complication rate was 36%. Surgical complications were bleeding, haematoma and intra-abdominal abscesses. CONCLUSION: Laparoscopic assisted transgastric ERCP is feasible, but there are several complications related to the procedure. Thus, until better alternative treatments are developed, it is recommended that the procedure should be performed at centres with both high endoscopic and bariatric expertise.

The IGF-Axis and Diabetic Retinopathy Before and After Gastric Bypass Surgery.

BACKGROUND: Laparoscopic gastric bypass (LGB) abruptly causes remission of type 2 diabetes (T2D). Such dramatic metabolic changes have previously been found to cause worsening of diabetic retinopathy (DR) and circulating insulin-like growth factor I (IGF-I) has been suggested as a causal mediator. We aimed to evaluate baseline imbalances in the circulating IGF-system and changes after LGB in patients with T2D. METHODS: Prospective ocular examinations and measurement of the IGF-axis before and 3 and 12 months after LGB. IGF-bioactivity was measured by cell-based IGF-I receptor (IGF-IR) kinase activation assay (bioactive IGF). Total IGF-I, IGF-II and IGF binding protein (IGFBP) 1 and 3 were determined by immunoassays. RESULTS: At baseline, 18 of 36 patients presented with DR. These patients had higher levels of bioactive IGF (p = 0.03) than patients without DR and this association was strengthened in multivariate analysis (p = 0.006). Three patients had worsening of DR, unrelated to other markers. In univariate analysis, bioactive IGF increased at 3 months (p = 0.05) but this change became insignificant in multivariate analysis (p = 0.11). IGFBP-1 increased whereas IGFBP-3 and total IGF-II decreased at the two postoperative visits (p ≤ 0.001). Total IGF-I showed no significant changes. HbA1c, glucose, HOMA-IR and lipids improved after surgery. Two patients did not complete the 12-month visit. CONCLUSIONS: In obese T2D patients, bioactive IGF is a potential biomarker for DR and levels tended to increase 3 months after bariatric surgery. IGFBP-1 increased while IGFBP-3 and total IGF-II decreased postoperatively, but these changes were unassociated with the development of DR. Markers of the metabolic syndrome improved.

Childhood trauma and diurnal cortisol disruption in fibromyalgia syndrome.

Adults with fibromyalgia syndrome report high rates of childhood trauma. Neuroendocrine abnormalities have also been noted in this population. Exploratory analyses tested relationships between retrospective reports of childhood trauma and diurnal salivary cortisol patterns among 85 women with fibromyalgia. Subjects with fibromyalgia completed self-reports of childhood physical, sexual and emotional abuse, as well as emotional and physical neglect. Recent major life events, current perceptions of stress, and depressive symptoms were also assessed. Salivary cortisol was collected six times per day for two consecutive days to assess diurnal rhythm, awakening response and mean cortisol levels. Hierarchical regression analyses were performed, controlling for age, relevant medications, life events, perceived stress, and depressive symptoms. Childhood physical abuse predicted flattened diurnal cortisol rhythms as well as greater cortisol responses to awakening. Sexual abuse was a second predictor of increased awakening cortisol responses. Patients with a history of trauma had markedly low levels of cortisol at the time of first awakening, partly explaining the results. These findings suggest that severe traumatic experiences in childhood may be a factor of adult neuroendocrine dysregulation among fibromyalgia sufferers. Trauma history should be evaluated and psychosocial intervention may be indicated as a component of treatment for fibromyalgia.
