The Benefits of a Therapeutic Exercise and Educational Intervention Program on Central Sensitization Symptoms and Pain-Related Fear Avoidance in Breast Cancer Survivors

BackgroundCentral sensitization symptoms and pain-related fear avoidance are two common problems in breast cancer survivors. Non-pharmacologic interventions such as therapeutic exercise and patient education can be effective in this population.AimsThis study aimed to: (1) analyze the benefits of a therapeutic exercise and educational program on central sensitization symptoms and pain-related fear avoidance in breast cancer survivors, and (2) explore the association between pain-related fear avoidance and central sensitization symptoms.DesignA single group pre–post intervention study was conducted.MethodsPatients were recruited from the service of Medical Oncology of the University Clinical Hospital Virgen de la Victoria, in Málaga (Spain). The intervention consisted of a therapeutic exercise and educational program that lasted 12 weeks, twice a week, for 1 hour. Two instruments were used: the Spanish version of the Central Sensitization Inventory and the Spanish Fear Avoidance Components Scale.ResultsA total of 82 breast cancer survivors participated in the study. Pre–post change on Central Sensitization Inventory was statistically significant (p = .007). There was a trend towards a significant difference for the Spanish Fear Avoidance Components Scale (p = .062). There was a statistically significant correlation between pain-related fear avoidance and central sensitization symptoms (r = 0.536, p < .001).ConclusionsThe current study has provided preliminary evidence on the benefits of this intervention in pain-related fear avoidance and central sensitization symptoms in breast cancer survivors. The Spanish version of the Central Sensitization Inventory and the Spanish Fear Avoidance Components Scale demonstrated responsiveness to change.     

Pretreatment Psychoneurological Symptoms and Their Association With Longitudinal Cognitive Function and Quality of Life in Older Breast Cancer Survivors

Context

Symptoms affect quality of life (QOL), functional status, and cognitive function in cancer survivors, but older survivors are understudied.

The effect of symptom clusters on functional status and quality of life in women with breast cancer

PurposeThe purposes of this study of women with breast cancer receiving chemotherapy with/without radiation therapy were to determine whether: (1) subgroups of oncology outpatients can be identified based on a specific symptom cluster (i.e., pain, fatigue, sleep disturbances, depression); (2) these subgroups differ on outcomes (i.e., functional status, quality of life); (3) subgroup membership changes over time.MethodsA secondary data analysis using data collected from 112 women at initial chemotherapy. Symptom and outcome measures were completed at three time points: baseline (i.e., the week before cycle two – T1); end of cancer treatment (T2), end of the study (approximately one year after the start of chemotherapy – T3). Cluster analysis identified patient subgroups based on symptom severity scores.ResultsAt T1 and T2, four patient subgroups were identified: ALL LOW (one or no symptom greater than the cut score), MILD (two symptoms), MODERATE (three or four symptoms), and ALL HIGH (four symptoms). At T3, three subgroups were identified: MILD, MODERATE and ALL HIGH. Subgroups with high severity levels of all four symptoms had poorer functional status and QOL at each time point than other subgroups (p < 0.001). Group membership changed over time.ConclusionsSubgroups of patients with different symptom experiences were identified. For some patients severity of all four symptoms persisted months after cancer treatment. Initial and ongoing assessment to identify those patients in the ALL HIGH patient subgroup is important so that appropriate interventions to improve functional status and quality of life can be offered.     

Symptom Cluster Experience Profiles in Adult Survivors of Childhood Cancers

Although aggressive medical treatment protocols have led to 80% five-year survival rates for most childhood cancer patients, many long-term survivors experience multiple troubling symptoms. Using data from 100 adult survivors of childhood cancers (ACC-survivors), we used latent variable mixture modeling to generate unique subgroups of survivors based on their experiences with a cluster of eight symptoms: lack of energy, worry, pain, difficulty sleeping, feeling irritable, feeling nervous, difficulty concentrating, and feeling sad (as measured by the Memorial Symptom Assessment Scale). We also examined factors that were likely to predict subgroup membership (chronic health conditions [CHCs], health-promoting lifestyle, and demographic variables) and determined the extent to which satisfaction with quality of life (QoL) varied across the subgroups. The final mixture model included three subgroups of ACC-survivors: high symptoms (HS; n = 21), moderate symptoms (MS; n = 45), and low symptoms (LS; n = 34). ACC-survivors who reported at least one CHC were six times as likely to be classified in the HS subgroup as compared with the LS subgroup. Mean health-promoting lifestyle scores were lowest in the HS subgroup and highest in the LS subgroup. Differences in QoL among the subgroups were statistically significant, thus validating that the subgroups were characterized uniquely for identifying those symptoms with highest life impact. To our knowledge, we are the first to identify distinct subgroups of ACC-survivors differentiated by symptom cluster experience profiles. The findings warrant additional research to confirm the subgroup-specific symptom cluster experience profiles in larger studies of ACC-survivors.     

Perceived symptoms and the supportive care needs of breast cancer survivors six months to five years post-treatment period

PurposeThis study characterized the range and levels of perceived symptoms and unmet needs reported by breast cancer survivors in the half-year to five year post-treatment period, and determined whether the symptoms can be a predictor of unmet needs.MethodsIn a cross-sectional study, 150 breast cancer survivors (mean age: 55.1 ± 8 years) at the half-year to five year post-treatment period were enrolled for analysis. The measuring scales used included the Memorial Symptom Assessment Scale (MSAS), and the Supportive Care Needs Survey Short Form (SCNS-SF34).Results88% of the survivors reported having at least one symptom, while 51% reported at least one unmet need. Lack of energy was the most prevalent symptom (47%), followed by numbness/tingling in hands/feet (41%). Most of the survivors had unmet needs in the Health care system/Information domain (37% reported at least one unmet need for help), followed by Psychological needs (29%). The mean scores for the SCNS-SF34 domains, except for sexuality, were significantly higher in the high-symptom group (mean 17.6–32.2) compared with the low-symptom group (mean 3.5–22.3) (p < 0.01). Regression of the SCNS-SF34 domain scores against the MSAS scores revealed an increase in the explained variance of from 14% to 54%.ConclusionOur results suggest that breast cancer survivors continue to experience a multitude of symptoms, and the burden of symptoms may be associated with unmet needs across a range of domains.     

Assessing the feasibility of using acupuncture and moxibustion to improve quality of life for cancer survivors with upper body lymphoedema

PurposeWithin a three-step mixed-methods study to investigate using acupuncture and moxibustion (acu/moxa) in the management of cancer treatment-related upper body lymphoedema, Step 2 obtained preliminary data about: 1) whether acu/moxa can improve quality of life, 2) the most troublesome symptoms, and 3) adverse effects.Methods and sampleAn exploratory single-arm observational clinical study included breast (BC) and head and neck cancer (HNC) survivors with mild-to-moderate uncomplicated lymphoedema for ≥3 months, ≥3 months post active-cancer treatment, no active cancer disease, undergoing routine lymphoedema maintenance. Participants received seven individualised treatments (S1), and six optional additional treatments (S2). MYMOP, SF-36 and PANAS were administered at baseline, during each series, and at follow-up 4 and 12 weeks after end-of-treatment. The primary outcome was change in MYMOP scores at the end of each series.Key resultsOf 35 participants recruited, 30 completed S1 and S2, 3 completed S1, 2 were lost to the study. Mean MYMOP profile change scores for BC participants were 1.28 points improvement on a 7-point scale (sd = 0.93, p < 0.0001, n = 25) for S1; and 1.41 for S2 (sd = 0.94, p < 0.0001, n = 24). S1 HNC change scores were 2.29 points improvement (sd = 0.62, p < 0.0001, n = 7); and 0.94 for S2 (sd = 0.95, p = 0.06, n = 6). Changes in some SF-36 scores for BC participants were significant to 4 weeks after treatment. No serious adverse effects were reported.ConclusionThis small study suggests acu/moxa is an acceptable adjunct to usual care for cancer survivors with lymphoedema. Further rigorous research is warranted to explore the effectiveness of acu/moxa in reducing the symptom burden.     

The impact of cancer on the physical,psychological and social well-being of childhood cancer survivors

PurposeNotwithstanding the advances in medical treatment, childhood cancer survivors are at risk of adverse physical, psychological and social effects of the cancer treatment. The purpose of this study was to examine the impact of cancer and its treatments on the physical, psychological and social well-being of Hong Kong Chinese childhood cancer survivors.MethodA total of 137 childhood cancer survivors (aged 9–16 years), who had their medical follow-up in an oncology out-patient clinic were invited to participate in the study. Participants were asked to respond to the standardized measures of depressive symptoms and self-esteem. Additionally, 15 participants from the group were selected for a semi-structured interview.ResultsThe results revealed that more than half of the participants presented depressive symptoms. Results also found that the mean depressive symptom scores for childhood cancer survivors were statistically significant higher than those of school children without cancer (p = 0.01), while the mean self-esteem scores for the survivors were statistically significant lower (p < 0.01). Additionally, qualitative interviews indicated that cancer and its treatments have great impact on the daily life of childhood cancer survivors.ConclusionThe study reveals that cancer and its treatments have a great impact on the physical, psychological and social well-being of survivors. It is essential for healthcare professionals to develop appropriate interventions with the aim of promoting physical, psychological and social well-being for these children. Most importantly, it is crucial to help them develop a positive view of the impact that the cancer experience has upon their lives.     

Examining assessment methods of scapular motion: Comparing results from planar elevations and functional task performance

BackgroundScapular kinematics of breast cancer survivors are most often evaluated during arm elevation. However, known compensations exist during functional task performance. The purpose of this study was to determine if scapular kinematics of breast cancer survivors during arm elevation are related to scapular kinematics during functional task performance.MethodsScapular kinematics of 25 non-cancer controls and 25 breast cancer survivors (split by presence of impingement pain) during arm elevation in 3 planes and 3 reaching and lifting functional tasks were measured. Scapular upward rotation and scapulohumeral rhythm (SHR) at 30° increments of arm elevation were calculated. Between-group differences of upward rotation during arm elevation were evaluated with one-way ANOVAs (p < 0.05). The association of upward rotation angle and SHR during arm elevation and functional tasks was tested with Pearson correlations (p < 0.05).FindingsScapular upward rotation was reduced for the breast cancer survivor with pain at lower levels of arm elevation in each plane by up to 7.1° (p = .014 to 0.049). This is inconsistent with functional task results, in which upward rotation decrements occurred at higher levels of arm elevation. Upward rotation angles and SHR during arm elevation had an overall weak-to-moderate relationship (r = 0.003 to 0.970, p = .001 to 0.048) to values from functional tasks. Arm elevation during sagittal plane elevation demonstrated scapular upward rotation that was most closely associated to upward rotation during functional task performance.InterpretationInconsistent relationships suggests that clinical evaluations should adopt basic functional movements for scapular motion assessment to complement simple arm elevations.     

Symptom manageability in Swiss HIV-infected patients

BackgroundManaging symptoms in daily life is a challenging problem for people living with HIV. As traditional parameters used to identify symptoms needing management do not integrate aspects of daily living with symptoms, we introduced ‘perceived symptom manageability’ to fill this gap.AimThe aim of this study was to quantitatively explore ‘perceived symptom manageability’ in a sample of 268 persons living with HIV.MethodsSecondary analysis of existing cross-sectional data. Social support, gender, age, depressive and anxiety symptoms were bivariately and multivariately analyzed and related to symptom experience and manageability as measured by the HIV Symptom Assessment Scale and the HIV Symptom Manageability Scale.ResultsLeast manageable symptoms were hair loss, vomiting and insomnia. Multivariately, age (beta = ? .11; p = .024), symptom distress (beta = ? .62; p < .001) and total anxiety and depressive symptoms (beta = ? .18; p = .003) were statistically significant correlates of symptom manageability.ConclusionsAlthough a promising concept to identify symptoms needing management, further research employing primary data is recommended.     

Depressed mood in breast cancer survivors: Associations with physical activity,cancer-related fatigue,quality of life,and fitness level

PurposeOne out of five cancer survivors suffer from depression after oncology treatment. The aim of this study was to examine the relationship between depression and quality of life (QoL), cancer-related symptoms, physical activity level, health-related fitness, and salivary flow rate in breast cancer survivors.Method108 breast cancer survivors in the year after the conclusion of treatment were included in this cross-sectional study. Demographic and clinically relevant information, cancer-related fatigue (Piper Fatigue Scale), QoL (QLQ-Br23 module), pain intensity VAS scale, salivary flow rate, physical activity level (Minnesota Leisure Time Physical Activity Questionnaire), and health-related fitness were assessed in all participants. Depressed mood was measured with the Profile of Mood States (POMS) Depression subscale.ResultsSignificant positive correlations between depressed mood and fatigue, systemic side effects, perceived shoulder pain, and breast-arms symptoms (r ranged between .57 and .28, P < .01) were found. In addition, significant negative correlations between depressed mood and body image, future perspective, force handgrip, and physical activity level (r ranged between −.41 and −.19; p < .05) were found. Regression analyses revealed that cancer-related fatigue, physical activity level, systemic side effects, and body image were significant predictors of depressed mood, and when combined, they explained 39.6% of the variance in depressed mood.ConclusionsCancer-related fatigue, physical activity level, and QoL partially explain the variability of depressed mood in breast cancer survivors. This paper facilitates a better understanding of the relationship between depressed mood and possible factors associated with it.     

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.     

Chronic Pain and Depression are Increased in Outpatient Adults with Somatic Symptoms from Secondary Health Care Services

BackgroundSomatic symptom disorder is described as excessive thoughts, feelings, or behaviors related to physical symptoms. The presence of somatic symptoms has been associated with depression, alexithymia, and the presence of chronic pain. Individuals with somatic symptom disorder are frequent attenders of primary health care services.AimWe focused on investigating if the presence of psychological symptoms, alexithymia, or pain could be risk factors for somatic symptoms in a secondary health care service.MethodsA cross-sectional and observational study. A total of 136 Mexican individuals who regularly attend a secondary health care service were recruited. The Visual Analogue Scale for Pain Assessment, the Symptom Checklist 90, and the Patient Health Questionnaire-15 were applied.ResultsOf all the participants, 45.2% showed somatic symptoms. We observed that these individuals more frequently presented with complaints of pain (χ² = 18.4, p < .001), as well as more severe (t = –4.6, p < .001), and prolonged (χ² = 4.9, p = 0.02). They also exhibited higher severity in all psychological dimensions assessed (p < .001). Finally, cardiovascular disease (t = 2.52, p = .01), pain intensity (t = 2.94, p = .005), and SCL-90 depression (t = 7.58, p < .001) were associated with somatic symptoms.ConclusionsIn this study, we observed a high frequency of somatic symptoms in outpatients attending secondary health care services. They may be accompanied by comorbid cardiovascular conditions, higher pain intensity, and other mental health-related symptoms, which may aggravate the general clinical picture presented by the patient seeking health care. The presence and severity of somatization should be taken into consideration in the first and second level health care services for an early mental state evaluation and treatment of these outpatients to have a better clinical assessment and health outcome.     

One-year survival in patients with solid tumours discharged alive from the intensive care unit after unplanned admission: A retrospective study

PurposeOutcomes in cancer patients after unplanned ICU admission was reassessed.Methodsretrospective cohort of patients with solid tumours admitted to ICU over a 10 years period.Results622 patients (age 62 [53–70]) were analysed. The most common primary sites of cancer were lung (n = 133; 21.4%) and digestive tract (n = 126; 20.2%) The ICU mortality rate was 22.2% (n = 138). Among 470 ICU survivors, the 1-year mortality was 41.3% (95% CI, 36–45.9) (n = 167). Factors independently associated with 1-year mortality were ICU admission after 2010 (HR 0.53 (0.37–0.76), p < .001), disease status (respectively, HR = 1.88 (1.0.2–3.45), p = .002) for locally advanced cancer and HR = 2.23 (1.35–3.67), p = .003) for metastatic cancer), poor performance status (HR = 1.58 (1.08–2.31), p = .019), newly diagnosed cancer at ICU admission (HR = 2.02 (1.28–3.20), p = .003), inability to receive oncologic treatment after ICU discharge (HR = 5.34 (3.49–8.18), p < .001) and decision to withhold life-sustaining treatment during ICU stay (HR = 2.34 (1.50–3.65), p < .001).ConclusionsAmong the factors associated with one-year mortality after ICU discharge, the possibility of receiving oncologic treatment after ICU discharge seems crucial.     

Clinical relevance of depressed kynurenine pathway in episodic migraine patients: potential prognostic markers in the peripheral plasma during the interictal period

BackgroundAltered glutamatergic neurotransmission and neuropeptide levels play a central role in migraine pathomechanism. Previously, we confirmed that kynurenic acid, an endogenous glutamatergic antagonist, was able to decrease the expression of pituitary adenylate cyclase-activating polypeptide 1–38, a neuropeptide with known migraine-inducing properties. Hence, our aim was to reveal the role of the peripheral kynurenine pathway (KP) in episodic migraineurs. We focused on the complete tryptophan (Trp) catabolism, which comprises the serotonin and melatonin routes in addition to kynurenine metabolites. We investigated the relationship between metabolic alterations and clinical characteristics of migraine patients.MethodsFemale migraine patients aged between 25 and 50 years (n = 50) and healthy control subjects (n = 34) participated in this study. Blood samples were collected from the cubital veins of subjects (during both the interictal/ictal periods in migraineurs, n = 47/12, respectively). 12 metabolites of Trp pathway were determined by neurochemical measurements (UHPLC-MS/MS).ResultsPlasma concentrations of the most Trp metabolites were remarkably decreased in the interictal period of migraineurs compared to healthy control subjects, especially in the migraine without aura (MWoA) subgroup: Trp (p < 0.025), L-kynurenine (p < 0.001), kynurenic acid (p < 0.016), anthranilic acid (p < 0.007), picolinic acid (p < 0.03), 5-hydroxy-indoleaceticacid (p < 0.025) and melatonin (p < 0.023). Several metabolites showed a tendency to elevate during the ictal phase, but this was significant only in the cases of anthranilic acid, 5-hydroxy-indoleaceticacid and melatonin in MWoA patients. In the same subgroup, higher interictal kynurenic acid levels were identified in patients whose headache was severe and not related to their menstruation cycle. Negative linear correlation was detected between the interictal levels of xanthurenic acid/melatonin and attack frequency. Positive associations were found between the ictal 3-hydroxykynurenine levels and the beginning of attacks, just as between ictal picolinic acid levels and last attack before ictal sampling.ConclusionsOur results suggest that there is a widespread metabolic imbalance in migraineurs, which manifests in a completely depressed peripheral Trp catabolism during the interictal period. It might act as trigger for the migraine attack, contributing to glutamate excess induced neurotoxicity and generalised hyperexcitability. This data can draw attention to the clinical relevance of KP in migraine.Supplementary InformationThe online version contains supplementary material available at 10.1186/s10194-021-01239-1.     

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.
