Effects of repetitive transcranial magnetic stimulation on fear of cancer recurrence and its underlying neuromechanism.

Introduction: Many breast cancer patients suffer from fear of cancer recurrence (FCR). However, effective physical intervention for FCR has been scarce. Previous studies have confirmed that repetitive transcranial magnetic stimulation (rTMS) can help improve patients' anxiety, depression, fear, and stress level. Therefore, this study aims to assess the efficacy of rTMS in the treatment of FCR in breast cancer patients and explore its underlying neural mechanism. Methods and analysis: and analysis: Fifty breast cancer patients with high FCR (FCR total score >27), and fifty age- and gender-matched patients with low FCR (FCR total score <7) will be recruited to participate in this study. Patients in the high FCR group will be randomly assigned to receive 4-week low-frequency rTMS targeting the right dorsolateral prefrontal cortex (rDLPFC) + treatment as usual (TAU) (n = 25), or to receive sham stimulation + TAU (n = 25). Patients in the low FCR group will only receive TAU. All participants will take a baseline fMRI scan to examine the local activities and interactions of brain activity between the prefrontal cortex (DLPFC), amygdala and hippocampus. Fear of Cancer Recurrence Questionnaire (FCRQ7), Patient Health Questionnaire (PHQ9), Generalize Anxiety Disorder (GAD7), Numeric Rating Scale (NRS), and Insomnia Severity Index (ISI7) will be used to measure an individual's FCR, depression, anxiety, pain, and insomnia symptoms at week 0 (baseline), week 4 (the end of intervention), week 5 (1 week post-treatment), week 8 (1 month post-treatment), and week 16 (3 months post-treatment). Participants in the high FCR group will receive a post-treatment fMRI scan within 24 h after intervention to explore the neural mechanisms of rTMS treatment. The primary outcome of the study, whether the rTMS intervention is sufficient in relieving FCR in breast cancer patients, is measured by FCRQ7. Additionally, task activation, local activity and functional connectivity of the DLPFC, amygdala and hippocampus will be compared, between high and low FCR group, and before and after treatment. Discussion: Studies have shown that low-frequency rTMS can be used to treat patient's FCR. However, there is a lack of relevant evidence to support the efficacy of rTMS on FCR in cancer patients, and the neural mechanisms underlying the effects of rTMS on FCR need to be further investigated. Ethics and dissemination: Ethical approval for the study has been obtained from the Ethics Committee of Guangdong Provincial People's Hospital (reference number: KY-N-2022-136-01). The results of the investigation will be published in scientific papers. The data from the investigation will be made available online if necessary. Trial registration: NCT05881889 (ClinicalTrials.gov). Date of registration: May 31, 2023.

Comparison of the EPDS and PHQ-9 in the assessment of depression among pregnant women: Similarities and differences.

BACKGROUND: Perinatal depression has attracted increasing attention. However, a detailed investigation of the network structure of depression is still lacking. We aim to examine the similarities and differences between the Edinburgh Postnatal Depression Scale (EPDS) and Patient Health Questionnaire (PHQ-9) from a network perspective. METHODS: A cross-sectional study was conducted from August 2020 to March 2022. We followed the STROBE checklist to report our research. Pregnant women (n = 2484) were recruited. All participants completed the EPDS and PHQ-9. We mainly used network analyses for statistical analysis and constructed two network models: the EPDS and PHQ-9 models. RESULTS: The detection rates of prenatal depression measured by the EPDS and PHQ-9 were 30.2 % and 28.2 %, respectively. In the EPDS network, the EPDS8 'sad or miserable' node (strength = 1.2161) was the most central node, and the EPDS10 'self-harming' node (strength = 0.4360) was the least central node. In the PHQ-9 network, the PHQ4 'fatigue' node (strength = 0.9815) was the most central node, and PHQ9 'suicide' was the least central symptom (strength = 0.5667). For both models, 'sad' acted as an important central symptom. CONCLUSIONS: Psychological symptoms may be more important in assessing depression using the EPDS, while physical symptoms may be more influential in assessing depression using the PHQ-9. For both the EPDS and PHQ-9, "sad" was an important central symptom, suggesting that it may be the most important target for further maternal depression interventions in the future.

Predictors and trajectories of fear of cancer recurrence in Chinese breast cancer patients.

OBJECTIVE: Fear of cancer recurrence (FCR) is one of the most common and aversive psychological phenomena among cancer patients. This study explored the trajectories of FCR over the 18 months following discharge, and evaluated the associations between baseline demographic and clinical variables and FCR trajectories among Chinese women treated for breast cancer. METHODS: This is a longitudinal prospective study. All participants were asked to completed a battery of questionnaires (FCR-7, PHQ-9, GAD-7 and MPQ-VAS) at baseline, 6, 12, and 18 months after discharge. Generalized linear mixed model and group-based trajectory analyses were conducted. RESULTS: Three hundred women with breast cancer were recruited. Latent class growth modeling analysis showed that three-group trajectory solution was the best fitting (i.e., 'intermediate level-stable group' (63.3%), 'low level-increasing group' (18.3%), and 'high level-decreasing group' (18.3%). Patients reported significant higher FCR at baseline assessment compared to other time points. Significant positive associations were found between anxiety, depression and FCR. Patients who had no baseline depression (estimate = -2.14, 95% CI: -2.78-(-1.51), P < 0.001) or anxiety (estimate = -2.77, 95% CI: -3.44-(-2.10), P < 0.001) tended to report significant lower FCRs over time. Women with none/mild life stress exhibited significant lower FCRs than those with moderate/high life stress, and participants with a family history of cancer or pessimism reported higher FCRs. CONCLUSION: >60% of the breast cancer women showed intermediate level-stable FCRs over the 18 months after discharge. Baseline anxiety, depression, life stress, family cancer history and pessimism predicts higher FCR levels. Clinical teams responsible for continuing patient care following treatment should develop clearer strategies for management of FCR.

Group-based trajectory and predictors of anxiety and depression among Chinese breast cancer patients.

Background: The aim of the current study is to investigate the change in anxiety and depression amongst Chinese breast cancer patients and to identify causal associations between baseline variables and the trajectory of anxiety and depression within this identified group. Methods: This is a longitudinal prospective study. Three hundred women with breast cancer were recruited. Patient's depression and anxiety were repeatedly measured by PHQ-9 and GAD-7 at baseline, 6, 12, and 18 months after discharge. The SAS 9.4 PROC Traj procedure was used to examine the group-based trajectory of these recruited patients. Linear mixed models (LMM) were utilized to examine anxiety/depression changes over time, accounting for relevant baseline demographic and clinical factors. Results: About 26.3% of the participants reported none or very mild anxiety over time, 60.7% reported stable low-level anxiety, and the remaining 13.0% showed significantly decreasing trend in GAD total scores. Meanwhile, 10.7% of the participants reported none or very mild depressive symptoms over time, 66.0% reported stable PHQ total scores throughout the research period, and 23.3% were classified as the "high level-decreasing group". Patients reported significantly higher anxiety and depression scores in the first three assessments. Participants with no or mild life stress along with a positive personality tended to report lower anxiety and depression scores over time. Conclusion: Most of the breast cancer patients reported stable low-level anxiety and depression 18 months after discharge. Early assessment of optimism and stress levels among cancer patients might help identify people at risk of experiencing long-term anxiety and depression.

Alleviating Excessive Worries Improves Co-Occurring Depression and Pain in Adolescent and Young Adult Cancer Patients: A Network Approach.

Objective: Anxiety, depression, and pain are highly interactive with each other in adolescent and young adult (AYA) cancer patients. This study aims to map out the connectivity between anxiety, depression and pain symptoms amongst Chinese AYA cancer patients from the perspective of a network model. Methods: Two hundred and eighteen AYA patients, aged between 15 and 39 years at diagnosis; completed the Patient Health Questionnaire (PHQ), Generalized Anxiety Disorder (GAD), and McGill Pain Questionnaire-Visual Analogue Scale (MPQ-VAS). Network analyses were performed. Results: In all, 38.07% (95% CI = 31.58-44.57%) of the participants reported depression, 30.73% (95% CI = 24.56-36.91%) reported anxiety, and 14.22% (95% CI = 9.55-18.89%) reported current pain. The generated network illustrated that anxiety, depression and pain community were well connected. In the network, "having trouble relaxing" (GAD4, node strength = 1.182), "uncontrollable worry" (GAD2, node strength = 1.165), and "sad mood" (PHQ2, node strength = 1.144) were identified as the most central symptoms, while "uncontrollable worry" (GAD2, bridge strength = 0.645), "guilty" (PHQ6, bridge strength = 0.545), and "restlessness" (GAD5, bridge strength = 0.414) were the key bridging symptoms that connected different communities. Conclusion: Anxiety, depression and pain symptoms are highly interactive with each other. Alleviating AYA cancer patient's excessive worries might be helpful in improving the patient's co-occurring anxiety, depression and pain symptoms.

Network connectivity between fear of cancer recurrence, anxiety, and depression in breast cancer patients.

BACKGROUND: Fear of cancer recurrence (FCR), anxiety, and depression are common psychological disturbances that frequently occur together among cancer patients. This study investigated network connectivity between FCR, anxiety, and depressive symptoms in a large representative sample of breast cancer patients. METHODS: This was a multicenter, cross-sectional study of 803 women with breast cancer. All participants completed the 4-item FCR scale, Generalized Anxiety Disorder Scale (GAD-7), and Patient Health Questionnaire (PHQ-9). Network analysis was conducted to investigate the network structure, central symptoms, bridge symptoms, and network stability of these disturbances. RESULTS: The generated network model indicated that anxiety and depression symptom communities were well-connected with each other, while FCR emerged as a distinct cluster with only a few weak links to anxiety and depression communities. Depressive and anxiety symptoms were more central than FCR symptoms were in the model. 'Having trouble relaxing' (#GAD4, strength = 1.147) was the most central node within the whole network, and 'strong feelings about recurrence' (#FCR4, strength = 0.531) was the least central node. Several anxiety symptoms (e.g., 'feeling afraid', 'uncontrollable worry', and 'restlessness') acted as important bridging symptoms connecting FCR, depression and anxiety communities. 'Uncontrollable worry' (#GAD2) had the highest node-specific predictive betweenness value. The network stability of this model was high. CONCLUSION: Depression and anxiety symptoms are highly interactive with each other among women with breast cancer. Conversely, FCR may have attenuated relations with anxiety and depression communities and emerged as a relatively independent, unique experience. Anxiety symptoms, particularly 'uncontrollable worry', acted as important trans-diagnostic symptoms that connected different communities. Findings suggested interventions to alleviate excessive worries and enhance feelings of personal control might be helpful in preventing or reducing related symptoms of FCR, anxiety and depression.

Fear of Recurrence in Chinese Cancer Patients: Prevalence, Correlates, and Network Analysis.

BACKGROUND: Fear of cancer recurrence (FCR) is a significant issue for most cancer patients. Until now, a detailed investigation of the structure of FCR and the interaction among its constituent elements is lacking. This study aims to investigate the phenomenon of FCR by means of network analysis in Chinese cancer patients. METHODS: This is a multi-center, cross-sectional study that included 996 cancer patients from southern China. All participants were assessed by the 7-item Chinese version Fear of Cancer Recurrence Scale (FCR-7). Multivariate logistic regression, and network analyses were conducted. Central symptoms (nodes) in the FCR network were identified. RESULTS: Among the 996 patients, 543 (54.52%) reported moderate FCR, and 137 (13.76%) reported high FCR. Chemotherapy (OR = 2.954, P = 0.016), and childhood severe illness experience (OR = 2.331, P = 0.016) were positively associated with high FCR, while higher monthly income (OR = 0.403, P = 0.046) was negative associated with high FCR. The node #FCR2 (Worried/anxious about recurrence) was the most central node within the FCR network (Strength = 1.190), while node #FCR6 (Examining for physical signs) was the least central node (Strength = 0.373). The edge FCR1-FCR2 ("Afraid"-"Worried/anxious") was the thickest and most saturated edge in the network. After controlling for age and gender, an almost identical network was obtained with respect to edges magnitude and strength. CONCLUSION: Fear of recurrence is a frequently reported issue among Chinese cancer patients. Patients with chemotherapy and childhood severe illness experience were more vulnerable and should be particularly monitored. Compared to behavioral component (i.e., body checking, overscreening and overtreatment) and cognitive component (i.e., intrusions), emotional component (i.e., worry/anxious) is more central to identify FCR and might be potential targets for further interventions.

Maternal and Paternal Depression During Pregnancy in China: Prevalence, Correlates, and Network Analysis.

BACKGROUND: Depression is a commonly seen mental health concern for mothers and fathers during their transition to parenthood. This study aims to provide new insights into the prevalence of maternal and paternal depression, its demographic and clinical correlates, and its symptom network among Chinese pregnant women and their partners. METHODS: In this multicenter, cross-sectional study, 769 pregnant women and their partners were assessed by Edinburgh Postnatal Depression Scale (EPDS) from June 15th to Sep 15th, 2020 in southern China. Convenient sampling method was used. Univariate analyses, multivariate logistic regression, and network analyses were conducted. Networks of maternal and paternal depression were compared. RESULTS: In total, 60 (EPDS total score ≥13, 7.80%, 95% CI: 5.90-9.70%) women and 23 (2.99%, 95% CI: 1.78-4.20%) of these women's partners reported depression. Physical comorbidities (OR=2.664, P=0.003) was the only factor that was found to significantly correlate with maternal depression. Network analyses showed that the resulting networks were well connected and that there was significant difference of network structure between maternal and paternal depression (M=0.330, P<0.001). Centrality plot indicated that "sad or miserable" (strength=1.097) was the most central symptom in the maternal depression network, while "scared or panicky" (strength=1.091) was the most central node in the paternal network. The edge between "things have been getting on top of me" - "able to laugh and see the funny side of things" (difference: 0.153, P=0.020), and "scared or panicky" - "the thought of harming myself" (difference: 0.084, P<0.001) was significantly stronger in women's partners than that in pregnant women. CONCLUSION: Maternal and paternal depression during pregnancy could result in significant negative consequences. Symptoms like "sad or miserable" and "scared or panicky" are critical and might be potential targets for further interventions. Evidence-based treatments, such as pharmacology, psychotherapy, community reinforcement and family training, might be beneficial for parents with depression during and after the pregnancy.

Counselling and psychotherapy service use in Chinese sexual minority populations: a nationwide survey.

BACKGROUND: This study investigated the prevalence and factors associated with counselling and psychotherapy service use among Chinese sexual minority populations. METHODS: A nationwide cross-sectional study was performed using snowball sampling method, which led to the inclusion of 18,193 participants. Participants' sociodemographic background, clinical, and psychological data were gathered. Multivariate logistic regression analysis was performed to explore any associated factors. RESULTS: There were 2007 participants who had used counselling and psychotherapy service out of the total population. Among those who had used psychotherapy services, 80.2% participants perceived discrimination, 1.1% reported that they had been refused treatment by a counsellor and/or psychotherapist, 1.6% had experienced verbal harassment, and 8.4% reported that their counsellor and/or psychotherapist lacked knowledge and experience in treating sexual minorities. In addition, regression analyses indicated that those who were divorced/widowed, had religious beliefs, and those who had experienced discrimination, verbal harassment, and rejection for treatment by health professionals all had an increased likelihood of utilising counselling and psychotherapy service. CONCLUSIONS: Service providers and policy makers in China should improve the quality and availability of counselling and psychotherapy services to address the mental health needs of sexual minority populations.

Mental Health Outcomes in Perinatal Women During the Remission Phase of COVID-19 in China.

BACKGROUND: Since the middle of March, the COVID-19 outbreak has been well contained in China. The prevention and control measures for the outbreak have been downgraded to a normalized level. However, until now, the change in level of psychological health amongst perinatal women during the remission phase of the COVID-19 outbreak has not been investigated in China. The aim of this current study was to assess the symptoms of anxiety, depression, insomnia and quality of life (QOL) in perinatal women and to identify potential risk factors associated with these symptoms. METHODS: This was a cross-sectional, hospital-based survey conducted between March 25th till June 5th, 2020 in southern China. Convenient sampling method was adopted. Women's anxiety, depression, insomnia symptoms and QOL was examined through standardized measurements. Multivariate logistic regression and Analysis of Covariance (ANCOVA) was conducted for the same. RESULTS: A total of 625 perinatal women completed the study; of them, 195 women (31.2%, 95%CI=27.56%-34.84%) reported anxiety, 120 (19.2%, 95%CI=16.10%-22.30%) reported depression, and 87 (13.9%, 95%CI=11.20%-16.64%) experienced symptoms of insomnia. Previous adverse experiences during pregnancy was a significant risk factor for anxiety (OR=1.628, 95%CI=1.069-2.480, P=0.023), depression (OR=1.853, 95%CI=1.153-2.977, P=0.011), and insomnia (OR=2.160, 95%CI=1.290-3.616, P=0.003). Participants having infected friends/families/colleagues were more likely to report anxiety (OR=2.195, 95%CI=1.245-3.871, P=0.007) and depression (OR=2.666, 95%CI=1.482-4.794, P=0.001). Those women whose regular check-ups were severely interrupted by the COVID-19 were also more likely to experience symptoms of anxiety (OR=2.935, 95%CI=1.701-5.062, P<0.001) and insomnia (OR=2.195, 95%CI=1.098-4.390, P=0.026). CONCLUSION: The COVID-19 pandemic does affect the mental health and well being of perinatal women. Increased attention should be paid to women who have infected friends/families/colleagues and those with previous adverse experiences during pregnancy. Coping strategies that relieve psychological stress during the COVID-19 outbreak should be provided to prevent adverse outcomes for women and their infants.

Suicidal Ideation in Newly-Diagnosed Chinese Cancer Patients.

OBJECTIVE: Suicide is one of the main reasons cited behind the death rate of cancer, and suicidal ideation (SI) is the first step toward it. This study aimed to investigate the prevalence and associates of suicidal ideation in newly-diagnosed Chinese cancer patients. METHODS: This multicenter study was conducted from January 2018 to September 2019. Eligible participants were asked to complete a Case Record Form (CRF), the Patient Health Questionnaire (PHQ-9), General Anxiety Disorder Questionnaire (GAD-7), Fear of Cancer Recurrence Questionnaire (FCRQ-7), and McGill Pain Questionnaire-Visual Analogue Scale (MPQ-VAS). Univariate analyses and multivariate logistic regression analyses were conducted for assessment. RESULTS: Out of 603 patients, 91 (15.1%, 95%CI: 12.23%-17.96%) reported suicidal ideation in the last 2 weeks. Physical comorbidities (OR=1.808, P=0.039), childhood adversity experience (OR=5.999, P=0.001), cancer pain (OR=1.828, P=0.047), depression (OR=2.811, P=0.013), and anxiety (OR=6.532, P<0.001) were significantly associated with suicidal ideation. It was also found that patients who regularly exercised were less likely to report suicidal thoughts (OR=0.172, P=0.007). CONCLUSION: Physical comorbidities, body ache, and mood disturbances are possible risk factors for suicidal ideation that warrant further attention in clinical practice. Preventive measures, such as systematic screening and arrangement for regular check-ups, could be beneficial to lower the risk of suicide.

High Fear of Cancer Recurrence in Chinese Newly Diagnosed Cancer Patients.

BACKGROUND: Fear of cancer recurrence (FCR) is common among cancer patients and of high clinical relevance. This study explores the prevalence and correlates of FCR in Chinese newly diagnosed cancer population. METHODS: This is a multicentre, cross-sectional study that includes 996 patients with mixed cancer diagnosis. All recently diagnosed patients completed a questionnaire consisting of the following: Fear of Progression Questionnaire-Short Form (FoP-Q-SF), General Anxiety Disorder Questionnaire (GAD-7), and Patient Health Questionnaire (PHQ-9). Univariate analyses, multivariate logistic regression analyses, and structural equation modeling (SEM) was performed to examine the association between tested variables and FCR. RESULTS: Of the 996 patients, 643 (64.6%) reported high FCR (scored ≥ 34 in the FoP-Q-SF). Chemotherapy (OR = 1.941), Childhood severe illness experience (OR = 2.802), depressive (OR = 1.153), and anxiety (OR = 1.249) symptoms were positively associated with high FCR, while higher monthly income (OR = 0.592) was negatively associated with high FCR. SEM indicated that emotional disturbances (anxiety and depression) directly influenced FCR, while emotional disturbances partly mediated the association between personal monthly income and FCR. CONCLUSION: High FCR is a frequently reported problem among newly diagnosed cancer patients. Various factors increased the likelihood of the development of FCR. Flexible psychological interventions are needed for patients with high FCR.

Self-Perceived Pain in Chinese Patients With Cancer.

BACKGROUND: Pain is one of the most burdensome and prevalent symptoms cancer patient report and it has severe negative impact on patient's quality of life. The aim of this study is to estimate the prevalence of pain and to test the association between demographic, clinical, psychological factors, and self-assessed pain in Chinese cancer population. METHODS: A total of 553 cancer patients were recruited in this cross-sectional study. Patient's basic demographic data was collected by a study-designed information sheet, and patient's pain, sleep disturbance and psychological distress were assessed by several validated measurements (MPQ-SF, AIS, FoP-Q-SF, PHQ-9, and GAD-7). Descriptive statistics and hierarchical multiple regression analyses were performed. RESULTS: Of the 553 patients, 411 (74.32%) patients reported that they experience some degree of pain. Fear of progression, anxiety, insomnia, and depressive symptoms were significantly associated with different subscales and the overall pain score in bivariate correlation matrix. Insomnia, depressive symptoms, and fear of cancer progression were significant independent factors of cancer pain on multivariate analyses. CONCLUSION: Psychological factors play a great role in the relationship between objective pathophysiology and patient's subjective experience of pain. It is important to evaluate each individual in detail with respect to psychological distress and pain severity when planning treatment and rehabilitation.
