Tryptophan and Kynurenine Pathway Metabolites and Psychoneurological Symptoms Among Breast Cancer Survivors

BackgroundAmong breast cancer survivors, pain, fatigue, depression, anxiety, and sleep disturbance are common psychoneurological symptoms that cluster together. Inflammation-induced activation of the tryptophan-kynurenine metabolomic pathway may play an important role in these symptoms.AimsThis study investigated the relationship between the metabolites involved in the tryptophan-kynurenine pathway and psychoneurological symptoms among breast cancer survivors.DesignCross-sectional study.SettingParticipants were recruited at the oncology clinic at the University of Illinois Hospital & Health Sciences System. Participants/Subjects: 79 breast cancer survivors after major cancer treatment.MethodsWe assessed psychoneurological symptoms with the PROMIS-29 and collected metabolites from fasting blood among breast cancer survivors after major cancer treatment, then analyzed four major metabolites involved in the tryptophankynurenine pathway (tryptophan, kynurenine, kynurenic acid, and quinolinic acid). Latent profile analysis identified subgroups based on the five psychoneurological symptoms. Mann-Whitney U tests and multivariable logistic regression compared targeted metabolites between subgroups.ResultsWe identified two distinct symptom subgroups (low, 81%; high, 19%). Compared with participants in the low symptom subgroup, patients in the high symptom subgroup had higher BMI (p = .024) and were currently using antidepressants (p = .008). Using multivariable analysis, lower tryptophan levels (p = .019) and higher kynurenine/tryptophan ratio (p = .028) were associated with increased risk of being in the high symptom subgroup after adjusting for BMI and antidepressant status.ConclusionThe tryptophan-kynurenine pathway and impaired tryptophan availability may contribute to the development of psychoneurological symptoms.     

Sleep,fatigue, depression,and circadian activity rhythms in women with breast cancer before and after treatment: a 1-year longitudinal study

Purpose

Sleep disturbance, fatigue and depression are common complaints in patients with cancer, and often contribute to worse quality of life (QoL). Circadian activity rhythms (CARs) are often disrupted in cancer patients. These symptoms worsen during treatment, but less is known about their long-term trajectory.

Methods

Sixty-eight women with stage I-III breast cancer (BC) scheduled to receive ≥4 cycles of chemotherapy, and age-, ethnicity-, and education-matched normal, cancer-free controls (NC) participated. Sleep was measured with actigraphy (nocturnal total sleep time [nocturnal TST] and daytime total nap time [NAPTIME]) and with the Pittsburgh Sleep Quality Index (PSQI); fatigue with the Multidimensional Fatigue Symptom Inventory-Short Form (MFSI-SF); depression with the Center of Epidemiological Studies-Depression (CES-D). CARs were derived from actigraphy. Several measures of QoL were administered. Data were collected at three time points: before (baseline), end of cycle 4 (cycle 4), and 1 year post-chemotherapy (1 year).

Results

Compared to NC, BC had longer NAPTIME, worse sleep quality, more fatigue, more depressive symptoms, more disrupted CARs, and worse QoL at baseline (all p values <0.05). At cycle 4, BC showed worse sleep, increased fatigue, more depressive symptoms, and more disrupted CARs compared to their own baseline levels and to NC (all p values <0.05). By 1 year, BC’s fatigue, depressive symptoms, and QoL returned to baseline levels but were still worse than those of NC, while NAPTIME and CARs did not differ from NC’s.

Conclusion

Additional research is needed to determine if beginning treatment of these symptoms before the start of chemotherapy will minimize symptom severity over time.     

Prospective Longitudinal Evaluation of a Symptom Cluster in Breast Cancer

ContextSymptom cluster research expands cancer investigations beyond a focus on individual symptoms in isolation.ObjectivesWe conducted a prospective longitudinal study of sleep, fatigue, depression, anxiety, and perceived cognitive impairment in patients with breast cancer undergoing chemotherapy.MethodsPatient-reported outcome measures were administered prior to chemotherapy, at Cycle 4 Day 1, and six months after initiating chemotherapy. Participants were divided into four groups and assigned a symptom cluster index (SCI) score based on the number/severity of symptoms reported at enrollment.ResultsParticipants (N = 80) were mostly women (97.5%) with Stage II (69.0%) breast cancer, 29–71 years of age. Scores on all measures were moderately-highly correlated across all time points. There were time effects for all symptoms, except sleep quality (nonsignificant trend), with most symptoms worsening during chemotherapy, although anxiety improved. There were no significant group × time interactions; all four SCI groups showed a similar trajectory of symptoms over time. Worse performance status and quality of life were associated with higher SCI score over time.ConclusionWith the exception of anxiety, the coherence of the symptom cluster was supported by similar patterns of severity and change over time in these symptoms (trend for sleep quality). Participants with higher SCI scores prior to chemotherapy continued to experience greater symptom burden during and after chemotherapy. Early assessment and intervention addressing this symptom cluster (vs. individual symptoms) may have a greater impact on patient performance status and quality of life for patients with higher SCIs.     

Feasibility of Investigational Procedures and Efficacy of a Personalized Omega-3 Dietary Intervention in Alleviating Pain and Psychoneurological Symptoms in Breast Cancer Survivors

BackgroundBreast cancer survivors (BCS) are at risk for psychoneurological symptoms (PNS) and inflammation for years following cancer treatment. Fish, particularly salmon, provides a rich source of omega-3 long chain fatty acids (omega-3LC), which has an anti-inflammatory effect. However, the benefit of omega-3LC on PNS is not well-known.AimsThis study evaluated the feasibility and the initial efficacy of a personalized meal plan with dietary omega-3LC in reducing PNS.MethodsA prospective, randomized controlled trial design (n = 46) was used to evaluate the feasibility of a personalized meal plan using two omega-3LC dose levels (high and low omega-3LC) in reducing PNS including pain, depression, fatigue, sleep, and stress.ResultsThe recruitment rate was 4.9% with overall retention rate of 74% and 67.1% adherence to personalized meal plan and dietary procedures. Of participants who completed the investigation, 94% completed fish adherence logs and consumed ≥70% of the assigned quantity of fish. Saliva collection was 97.8% at baseline and 100% at follow-up. BCS in the high omega-3LC group had a significant decrease in pain (p < .01), perceived stress (p < .05), sleep (p < .001), depression (p < .001), and fatigue (p < .01) over the course of intervention. There were trends of PNS improvement in the low omega-3LC group but the differences did not reach statistical significance.ConclusionOur results support the feasibility of our investigational design, procedures, and intervention. The outcomes provide preliminary support for an expanded research effort using fish as a source of omega-3LC and personalized dietary planning as a vehicle for symptom self-management in BCS.     

Effect of Psycho-Educational Intervention to Reduce Anxiety and Depression at Postintervention and Follow-Up in Women with Breast Cancer: A Systematic Review and Meta-Analysis

ObjectivesTo examine the effectiveness of the psycho-educational intervention in reducing anxiety and depressive symptoms for women with breast cancer in post- and follow-up status.Data SourcesA systematic search of 16 electronic databases to identify all randomized controlled trial studies that examine the effects of psycho-education on anxiety and depression among women with breast cancer. The standardized mean differences (SMDs) between groups in depression and anxiety levels for postintervention and follow-up were computed for each study.ConclusionEvidence suggests that psycho-educational intervention effectively relieves anxiety and depressive symptoms among women with breast cancer postintervention and follow-up.Implications for PracticeA significant effect of the psycho-education intervention was found to reduce anxiety and depressive symptoms in women with breast cancer. Such service was recommended in nursing practice.     

Pain and Fatigue Variability Patterns Distinguish Subgroups of Fibromyalgia Patients

The current study examined between- and within-subject variability in pain-related symptoms as predictors of pain and fatigue, and identified patient subgroups on the basis of symptom variability characteristics. Two hundred fifty-six fibromyalgia (FM) patients completed daily diaries up to a period of 154 days and reported on symptoms of pain intensity, pain unpleasantness, fatigue, anxiety, and depressed mood. Measures of health status, quality of life, and somatic symptoms were obtained at baseline, and hierarchical linear modeling and cluster analyses were used. Significant intra- and interindividual variability in daily FM symptoms was observed. Higher levels of pain were associated with greater fluctuations in pain unpleasantness, fatigue, and depressed mood. Similar effects were observed for fatigue and individual variability in anxiety also emerged as a robust predictor. Three FM subgroups were revealed: low variability in symptoms (cluster 1), high symptom variability (cluster 2), and a mixed variability group characterized by low fluctuation in pain unpleasantness; moderate pain, fatigue, and depressed mood variability; and high anxiety variability (cluster 3). Cluster 3 exhibited lower social functioning and higher levels of pain, compared with cluster 1. These findings support the dynamic nature of FM pain and suggest the presence of FM subgroups on the basis of variation in mood and pain symptomatology.

The Effect of the Pain Symptom Cluster on Performance in Women Diagnosed with Advanced Breast Cancer: The Mediating Role of the Psychoneurological Symptom Cluster

Background: Pain, depression, anxiety, sleep disturbances, and constipation were reported in different symptom clusters at different stages of breast cancer. Managing symptom clusters rather than individual symptoms can improve performance status. Aim: The study examined the effect of pain symptom cluster (pain and constipation) on performance when mediated by the psychoneurological symptom cluster (depression, anxiety, and sleep disturbances) using age as a moderator. Design: A secondary analysis. Settings: Palliative care center at a tertiary medical center in northeast Ohio. Participants: Eighty-six women diagnosed with advanced breast cancer. Method: A quantitative cross-sectional approach. Results: Ordinal logistic regression showed that pain symptom cluster did not have a significant mediation effect on performance. Odds ratio indicated that subjects with pain symptom cluster were 63% more likely to be bedridden (odds ratio = 1.63, confidence interval = .69-3.84). Women who reported pain symptom cluster were 5% more likely to have psychoneurological symptom cluster (odds ratio = 1.05, confidence interval = .400-2.774). Stratified analysis of age showed no differences in performance. Post-hoc analysis showed that the components of pain symptom cluster had a significant effect on psychoneurological symptom cluster (odds ratio: 3 [1.18-7.62]). Conclusions: Pain, constipation, depression, anxiety, and sleep disturbances were highly prevalent in women with advanced breast cancer. However, they tended to cluster in different symptom clusters. Although some findings were not significant, they all supported the direction of the tested hypotheses. Variations in symptom clusters research, including methodology, instruments, statistical tests, and chosen symptom cluster correlation coefficient, should be addressed.     

Anxiety,depression and quality of life in Chinese women with breast cancer during and after treatment: A comparative evaluation

Purpose of the researchTo compare the psychological health and quality of life (QoL) of women with breast cancer, and to determine the relationship between anxiety, depression and QoL during treatment and one year afterwards.Methods and sampleFor this secondary analysis, 269 women undergoing adjuvant therapy for breast cancer, and 148 women with breast cancer who had completed all treatment within the last year completed a self-report questionnaire covering the Hospital Anxiety and Depression Scale-Cantonese/Chinese version, Functional Assessment of Cancer Therapy-General, and demographic and clinical characteristics.Key resultsThe ongoing-therapy group showed higher levels of anxiety and depression and lower levels of all QoL dimensions than the post-therapy group. Linear regression results showed that both anxiety and depression were significantly related to physical and functional well-being, while depression was associated with social/family well-being in both groups. In the case of emotional well-being, anxiety had a strong significant association in both groups and depression a significant relationship only in the ongoing-therapy group.ConclusionsThe psychological health of women with breast cancer is affected during and after treatment. Psychological distress in these patients, including anxiety and depression, has independent associations with impaired emotional, functional, physical and social well-being. The results highlight the importance of timely detection of anxiety and depression, and their proper management, during the treatment and survivorship phases of the breast cancer trajectory.     

The association of red meat consumption and mental health in women: A cross-sectional study

ObjectivesPrevious studies have shown that red meat consumption has beneficial effects on health. The purpose of this study was to determine the relationship between red meat consumption and depression, anxiety and psychological distress in Tehrani women.MethodsIn this cross-sectional study, 482 women aged 20-50 years old referred to the health centers of Tehran University of Medical Sciences in 2018 were selected by multistage cluster sampling. The usual dietary intake was evaluated using a semi-quantitative food frequency questionnaire containing 168 items that its validity and reliability were approved previously. The red meat category was defined as the sum of red meats (beef, lamb), and organ meats (beef liver, kidney, and heart, ruminant meat). Psychological disorders were assessed using a validated Depression, Anxiety, Stress Scales (DASS) questionnaires with 21-items. In the logistic regression analysis, the results were adjusted to the confounding factors.ResultsThe mean age of the study participants was 31.87 ± 7.6 years. The prevalence of depressive symptoms, anxiety and psychological distress among participants was 34%, 40% and 42%, respectively. After controlling for potential confounders, women in the highest quartile of red meat had a highest prevalence of depressive symptoms (OR: 2.51; 95% CI: 1.32–4.76; p = 0.002), anxiety (OR: 1.82; 95% CI: 1.00–3.29; p = 0.034) and stress (OR: 3.47; 95% CI: 1.88–6.42; p < 0.001) compared with those in the lowest quartile.ConclusionsWe found a significant association between red meat intake and mental health in women. Prospective studies are needed to confirm these findings.     

Identification of distinct subgroups of breast cancer patients based on self-reported changes in sleep disturbance

Purpose

The purposes of this study were to identify distinct subgroups of patients based on self-reported sleep disturbance prior to through 6 months after breast cancer surgery and evaluate for differences in demographic, clinical, and symptom characteristics among these latent classes.

Methods

Women (n?=?398) who underwent unilateral breast cancer surgery were enrolled prior to surgery. Patients completed measures of functional status, sleep disturbance (i.e., General Sleep Disturbance Scale (GSDS); higher scores indicate higher levels of sleep disturbance), fatigue, attentional fatigue, depressive symptoms, and anxiety prior to surgery and monthly for 6 months.

Results

Three distinct classes of sleep disturbance trajectories were identified using growth mixture modeling. The high sustained class (55.0%) had high and the low sustained class (39.7%) had low GSDS scores prior to surgery that persisted for 6 months. The decreasing class (5.3%) had high GSDS score prior to surgery that decreased over time. Women in the high sustained class were significantly younger, had more comorbidity and poorer function, and were more likely to report hot flashes compared to the low sustained class. More women who underwent mastectomy or breast reconstruction were in the decreasing class. Decreasing and high sustained classes reported higher levels of physical fatigue, attentional fatigue, depressive symptoms, and anxiety compared to the low sustained class.

Conclusions

A high percentage of women has significant sleep disturbance prior to surgery that persists during subsequent treatments (i.e., radiation therapy and chemotherapy). Clinicians need to perform routine assessments and initiate appropriate interventions to improve sleep prior to and following surgery.     

Fatigue in the mothers of children with cerebral palsy

Purpose: To evaluate fatigue in the mothers of children with cerebral palsy (CP), and to determine its associations with clinical parameters of CP, depression and quality of life (QoL). Method: Ninety children (50 girls and 40 boys) with spastic CP and their mothers were included. Control group comprised mothers of healthy children. Gross motor function classification system (GMFCS) was used for determining functional status. Spasticity was evaluated by using modified Ashworth scale. Fatigue symptom inventory (FSI) was used for assessing maternal fatigue, Nottingham health profile (NHP) for maternal QoL, and Beck Depression Scale (BDS) for maternal depression. Results: Mothers of children with CP scored significantly higher in all FSI subgroups (intensity of fatigue, duration of fatigue and interference with QoL), all NHP subgroups and BDS (p?p?< 0.01). No association was found between FSI and clinical parameters of children with CP including age, gender, type of CP, tonus and functional impairment (p?>?0.05). Conclusions: Our findings indicate that fatigue levels of mothers with CP children are higher than those with healthy children and associated with depression and deterioration in QoL in terms of physical, social and emotional functioning. This should be considered while designing a family centred rehabilitation programme for children with CP.

• Implications for Rehabilitation

• Caring for a child with cerebral palsy has psychological, social and financial impacts on familiesand is associated with increased levels of fatigue among mothers.

• The capacity of current programs and services needs to be strengthened to accommodate theneeds of children with CP and their mothers in order to reduce fatigue of mothers.

• New programs need to be developed to provide psychosocial support for the mothers andto reduce their fatigue as they continue to care for their children.

• Provision of assistive technology devices (particularly suitable wheelchairs) will be useful inreduction of fatigue levels of mothers.

     

Severe to profound hearing impairment: quality of life,psychosocial consequences and audiological rehabilitation

Abstract

Purpose: To study the quality of life (QoL) and psychosocial consequences in terms of sick leave and audiological rehabilitation given to patients with severe to profound hearing impairment. Method: A retrospective study of data on 2319 patients with severe to profound hearing impairment in The Swedish Quality Register of Otorhinolaryngology, followed by a posted questionnaire including The Hospital Anxiety and Depression Scale (HADS). Results: The results indicate greater levels of anxiety and depression among patients with severe or profound hearing impairment than in the general population, and annoying tinnitus and vertigo had strong negative effects on QoL. The proportion of sick leave differed between the studied dimensions in the study. The proportion of patients who received extended audiological rehabilitation was 38% in the present study. Conclusions: Treatment focused on anxiety, depression, tinnitus and vertigo must be given early in the rehabilitation process in patients with severe or profound hearing impairment. Because sick leave differs greatly within this group of patients, collaboration with the regional Social Insurance Agency is crucial part of the rehabilitation. The study also shows that presently, only a small proportion of patients in Sweden with severe to profound hearing impairment receive extended audiological rehabilitation.

• Implications for Rehabilitation

• Greater levels of anxiety and depression have been found among patients with severe or profound hearing impairment than in the general population, and annoying tinnitus and vertigo have strong negative effects on QoL in this group of patients.

• Only a small proportion of patients with severe to profound hearing impairment receive extended audiological rehabilitation today, including medical, technical and psychosocial efforts.

• Extended audiological rehabilitation focused on anxiety, depression, tinnitus and vertigo must be given, together with technical rehabilitation, early in the rehabilitation process in patients with severe or profound hearing impairment.

     

Personality and fatigue in patients with benign or malignant breast disease

Goals of work The aim of the study was to examine the role of five general personality traits in fatigue in a group of patients with breast cancer (BC) and a group with benign breast problems (BBP). Materials and methods Of the 304 participating women, 127 patients had BC and 177 BBP. A fatigue scale was completed before diagnosis and 1, 3, and 6 months after diagnosis (benign patients) or surgical treatment (BC patients). A personality questionnaire (NEO-FFI) and a depression scale (CES-D) were completed before diagnosis. Main results The BC group was less tired before diagnosis, more tired 1 month after diagnosis, and equally tired 3 and 6 months after diagnosis. In the total group, women were more tired over time when they were more neurotic, less agreeable, or more introverted. After controlling for depressive symptoms, demographics, and medical factors, baseline depressive symptoms (β = 0.29, p < 0.05), neuroticism (β = 0.29, p < 0.05), and extraversion (β = −0.25, p < 0.05) predicted fatigue 6 months later. After also including baseline fatigue, only neuroticism (β = 0.22, p < 0.05) and baseline fatigue (β = 0.79, p < 0.001) predicted fatigue. Conclusions Personality is more strongly related to fatigue than demographics, the diagnosis cancer, receiving cancer treatment, and baseline depressive symptoms and fatigue. When replicated, screening and treating women who are at risk to experience high levels of fatigue is recommended.     

Psychosocial diagnoses occurring after patients present with fatigue

ObjectiveTo discover the frequency of psychosocial and other diagnoses occurring at the end of a visit when patients present to their FPs with concerns about fatigue.DesignCross-sectional study of patient-FP encounters for fatigue.SettingTen FP practices in southwestern Ontario.ParticipantsA total of 259 encounters involving 167 patients presenting to their FPs between March 1, 2006, and June 30, 2010, with concerns about fatigue.ResultsPsychosocial diagnoses were made 23.9% of the time. Among psychosocial diagnoses made, depressive disorder and anxiety disorder or anxiety state were diagnosed more often in women (P = .048). Slightly less than 30% of the time, the cause of patients’ fatigue remained undiagnosed at the end of the encounter. A diagnosis was made more often in men.ConclusionCauses of fatigue frequently remain undiagnosed; however, when there is a diagnosis, psychosocial diagnoses are common. Therefore, it would be appropriate for FPs to screen for psychosocial issues when their patients present with fatigue, unless some other diagnosis is evident. Depression and anxiety could be considered particularly among female patients with fatigue.
