SPTLC2 ameliorates chondrocyte dysfunction and extracellular matrix metabolism disturbance in vitro and in vivo in osteoarthritis.

Disturbances in chondrocyte extracellular matrix (ECM) metabolism in osteoarthritis (OA) are a major cause of OA and potentially lead to personal disability, placing a huge burden on society. Chondrocyte apoptosis and ECM catabolism have a major role in the OA process. Firstly, bioinformatics analysis was performed to screen differentially expressed genes (DEGs) in OA, and serine palmitoyltransferase subunit 2 (SPTLC2) was chosen, which had high-level expression in the OA cartilage tissues and OA chondrocytes. Overexpression and knockdown of SPTLC2 were achieved in OA chondrocytes and normal chondrocytes respectively to study the effect of SPTLC2 upon ECM metabolism of chondrocytes. Cell viability and apoptosis were measured using MTT and flow cytometry analyses; SPTLC2 overexpression enhanced the OA chondrocyte viability and decreased apoptotic rate. In addition, Western blot detection of ECM-related factors (Collagen I, Collage II, MMP-1, MMP-3, and MMP-13) revealed that SPTLC2 overexpression promoted the expression of collagens (Collagen I and Collage II) and suppressed matrix metalloproteinase (MMP-1, MMP-3, and MMP-13) level. In contrast, SPTLC2 knockdown in normal chondrocytes showed opposite effects on cell viability, apoptosis, and ECM degeneration. The articular cartilage of OA rats was transfected with lentivirus overexpressing SPTLC2; HE and Safranin-O fast green demonstrated that SPTLC2 overexpression could alleviate chondrocyte injuries and slow down the development of OA. In conclusion, SPTLC2 plays a role in OA and may be a potential target gene for the treatment of OA.

The Effect of Attentional Bias on Emotions in Patients with Breast Cancer.

BACKGROUND: Attentional bias may influence the emotional experiences of breast cancer patients, both positively and negatively. This study aimed to investigate attentional bias in breast cancer patients and its impact on their emotions. METHOD: Thirty-eight breast cancer patients completed a modified dot-probe task and the Depression Anxiety and Stress Scale to assess attentional bias and emotional states. Attentional bias was measured by analyzing response times to different stimuli in the modified dot-probe task. Emotional stimuli included 80 pairs of facial images depicting sad-neutral, fearful-neutral, happy-neutral, and neutral-neutral expressions. Attentional bias components were observed at stimulus presentation durations of 300 ms and 1500 ms. Differences in emotional responses among breast cancer patients with varying attentional biases were compared. RESULTS: Breast cancer patients exhibited attentional avoidance of sad and happy stimuli at 300 ms. Further analysis revealed that patients who exhibited attentional avoidance of sad stimuli at 300 ms reported higher levels of anxiety and stress. Those with attentional avoidance of fearful stimuli at 1500 ms reported increased anxiety, while individuals showing attentional avoidance of happy stimuli or difficulty disengaging from happy stimuli at 1500 ms reported higher levels of depression and stress. CONCLUSION: Breast cancer patients demonstrated an attentional bias toward emotional stimuli, particularly avoidance of sad and happy stimuli in 300 ms. Different components of attentional bias were associated with distinct negative emotional outcomes.

A comparison of interferential current efficacy in elderly intervertebral disc degeneration patients with or without sarcopenia: a retrospective study.

BACKGROUND: Intervertebral disc degeneration and sarcopenia are both age-related diseases without effective treatments. Their comorbidities may worsen the prognosis, and further studies on interaction and therapy are needed. The purpose of the study was to investigate the prevalence of sarcopenia in intervertebral disc degeneration, and to compare the characteristics of intervertebral disc degeneration with and without sarcopenia and effects of interferential current. METHODS: One hundred twenty disc degeneration patients were included from 2021 to 2022 in a single institute. Medical records, examination results and radiological reports were reviewed. Patients with sarcopenia were screened and grouped according to Asian Working Group for Sarcopenia 2019. VAS, ODI, SARC-F, SMI, gait speed (GS), grip strength, disc Pfirrmann grading, standard cross-sectional area (SCSA), degree of fatty infiltration (DFF), and nerve conduction velocity (NCV) were assessed before and after treatment. RESULTS: The prevalence of sarcopenia in intervertebral disc degeneration was 28.3%. The difference of VAS, ODI, disc Pfirrmann grading, SCSA, DFF and NCV between two groups were significant before intervention (P < 0.05), SCSA and DFF were related to the degree of disc degeneration. The improvement of SMI, GS, grip strength, VAS, SARC-F and ODI in intervertebral disc degeneration with sarcopenia group was significant after intervention, as well as SMI, GS, grip strength, VAS and ODI in those without sarcopenia (P < 0.05). The improvement of grip strength, GS, ODI and SARC-F in intervertebral disc degeneration with sarcopenia group were greater than the one without sarcopenia (P < 0.05), whereas there was no significance in improvement degree of other indicators between the two groups (P > 0.05). CONCLUSION: The prevalence of sarcopenia was high in intervertebral disc degeneration, and paravertebral muscles degeneration correlated with the degree of disc degeneration. Compared to those without sarcopenia, intervertebral disc degeneration patients with sarcopenia have more severe pain, poorer mobility and neurological function. Interferential current is effective in intervertebral disc degeneration patients and sarcopenia patients.

Myth or fact: 3D-printed off-the-shelf prosthesis is superior to titanium mesh cage in anterior cervical corpectomy and fusion?

BACKGROUND: To find out if three-dimensional printing (3DP) off-the-shelf (OTS) prosthesis is superior to titanium mesh cages in anterior cervical corpectomy and fusion (ACCF) when treating single-segment degenerative cervical spondylotic myelopathy (DCSM). METHODS: DCSM patients underwent ACCF from January 2016 to January 2019 in a single center were included. Patients were divided into the 3DP group (28) and the TMC group (23). The hospital stays, operation time, intraoperative blood loss, and the cost of hospitalization were compared. The Japanese Orthopedic Association (JOA) scores and Neck Disability Index (NDI) were recorded pre-operatively, 1 day, 3, 6, 12, and 24 months post-operatively. Radiological data was measured to evaluate fusion, subsidence, and cervical lordosis. Patients were sent with SF-36 to assess their health-related quality of life (HRQoL). RESULTS: The differences in operative time, intraoperative blood loss, and hospital stay were not statistically significant between groups (p > 0.05). Postoperative dysphagia occurred in 2 cases in the 3DP group and 3 cases in the TMC group, which all relieved one week later. The difference in improvement of JOA and NDI between the two groups was not statistically significant (p > 0.05). No hardware failure was found and bony fusion was achieved in all cases except one in the 3DP group. The difference in cervical lordosis (CL), fused segmental angle (FSA), mean vertebral height (MVH), and subsidence rates between groups at each follow-up time point was not statistically significant and the results of the SF-36 were similar (p > 0.05). The total cost was higher in the 3DP group with its higher graft cost (p < 0.05). CONCLUSION: In treating single-segment DCSM with ACCF, both 3DP OTS prosthesis and TMC achieved satisfactory outcomes. However, the more costly 3DP OTS prosthesis was not able to reduce subsidence as it claimed.

Impact of Gender-Role Attitudes and Mental Health on Hostile Sexism and Acceptance of Cosmetic Surgery.

BACKGROUND: Each year, tens of thousands of people worldwide choose to undergo cosmetic surgery in order to alter their appearance. In recent years, young people have gradually emerged to comprise the main driving force behind the increasing demand for cosmetic surgery. Previous studies have found that sexism may motivate young people to undergo such surgeries. However, few studies have been conducted to determine if this psychological mechanism influences the acceptance of cosmetic surgery among Chinese university students. METHODS: A total of 579 Chinese university students (280 girls and 299 boys, 17-20 years) volunteered to participate in the online survey. They completed a questionnaire containing the Ambivalent Sexism Inventory, the 12-item General Health Questionnaire, the Gender-Role Attitudes Questionnaire and the Acceptance of Cosmetic Surgery Scale. We firstly evaluated the underlying factor structure of the Acceptance of Cosmetic Surgery Scale using exploratory and confirmatory factor analyses, and exploring pattern of associations between the constructs was analyzed via path analysis. RESULTS: According to the findings, hostile sexism was associated with greater levels of acceptance toward cosmetic surgery. Moreover, gender-role attitudes mediated the link between hostile sexism and the acceptance of cosmetic surgery, and this mediation was positively influenced by general mental health. CONCLUSION: Our study contributes to a deeper understanding of Chinese university students' attitudes toward cosmetic surgery, hostile sexism may contribute to normalizing traditional gender stereotypes and encourage cosmetic surgery acceptability among Chinese university students.

Spinal infection after vertebral augmentation: a covert complication with serious havoc.

INTRODUCTION: Vertebral augmentation, including percutaneous vertebroplasty (PVP) or kyphoplasty (PKP), is the current least invasive surgical option and has been widely used to treat the painful osteoporotic vertebral compression fractures (OVCF). However, the postoperative infections could be life-threatening, even though they rarely occur. Our studies aim to clarify the causation and outcomes of spinal infections following augmentation and meanwhile to identify the risk factors. METHODS: A retrospective study was conducted on patients with OVCF who underwent PVP or PKP, and were subsequently admitted to our institution with postoperative spinal infection between January 2010 and December 2022. A total of 33 patients were finally included. RESULTS: The rate of spinal infection after augmentation in our single institute was 0.05% (2/3893). In addition to these 2 patients, the remaining 31 were referred from other hospitals. All 33 patients exhibited elevated inflammatory parameters, 14 patients presented with fever, and 9 patients experienced neurological deficits. Additionally, 29 patients had comorbidity and risk factors. Pathogens were identified in 26 patients, while only 7 patients were examined as culture negative. 27 patients underwent revision surgery and 6 patients only received conservative therapy. Anterior surgery was performed in 2 patients, while posterior surgery was performed in 20 patients. A combined anterior-posterior surgery was performed in 5 patients. At the final follow-up, 18 patients had unrestricted mobility, 10 patients required assistance from crutches or a walker for ambulation, 4 patients needed a wheelchair, and 1 patients died after revision surgery. CONCLUSIONS: Spinal infection after vertebral augmentation is rare, but it cannot be ignored. Surgeons should make every effort to detect the potential preoperative spondylitis or discitis. Once postoperative spinal infection is confirmed, a prompt intravenous antibiotic therapy is warranted. If medication therapy fails, revision surgery involving debridement and spinal reconstruction should be considered.

[Microwave Heartprint: A novel non-contact human identification technology based on cardiac micro-motion detection using ultra wideband bio-radar].

The existing one-time identity authentication technology cannot continuously guarantee the legitimacy of user identity during the whole human-computer interaction session, and often requires active cooperation of users, which seriously limits the availability. This study proposes a new non-contact identity recognition technology based on cardiac micro-motion detection using ultra wideband (UWB) bio-radar. After the multi-point micro-motion echoes in the range dimension of the human heart surface area were continuously detected by ultra wideband bio-radar, the two-dimensional principal component analysis (2D-PCA) was exploited to extract the compressed features of the two-dimensional image matrix, namely the distance channel-heart beat sampling point (DC-HBP) matrix, in each accurate segmented heart beat cycle for identity recognition. In the practical measurement experiment, based on the proposed multi-range-bin & 2D-PCA feature scheme along with two conventional reference feature schemes, three typical classifiers were selected as representatives to conduct the heart beat identification under two states of normal breathing and breath holding. The results showed that the multi-range-bin & 2D-PCA feature scheme proposed in this paper showed the best recognition effect. Compared with the optimal range-bin & overall heart beat feature scheme, our proposed scheme held an overall average recognition accuracy of 6.16% higher (normal respiration: 6.84%; breath holding: 5.48%). Compared with the multi-distance unit & whole heart beat feature scheme, the overall average accuracy increase was 27.42% (normal respiration: 28.63%; breath holding: 26.21%) for our proposed scheme. This study is expected to provide a new method of undisturbed, all-weather, non-contact and continuous identification for authentication.

Facilitators and barriers in the development and implementation of depression prevention and treatment policies in China: a qualitative study.

BACKGROUND: Depression is one of the leading causes of avoidable suffering and premature death worldwide, leading to the disease burden among mental disorders. Depression-related deaths can be prevented by developing and implementing good depression prevention and treatment policies. The goal of this study is to provide theoretical direction and useful references for examining the outstanding service work of depression prevention and treatment. It also aims to describe how depression prevention and treatment policies were developed and put into practice in China, along with the associated facilitators and barriers. METHODS: We integrated two data sources using a case study approach: a document review of relevant policy documents, published articles and reports between 2004 and 2022 (N = 12 papers) and in-depth interviews (N = 41). Participants were drawn from pertinent sectors to managing depression: research and academia, relevant government departments, health care providers, people with depression and their families, and community organisations. Thematic analysis was used to analyse all data. RESULTS: A comprehensive programme of work exploring specific services for depression prevention and treatment was developed in China in 2020. Facilitators of policy development and implementation include (1) political commitment and strong leadership, (2) coordination mechanisms, (3) stakeholder enthusiasm and commitment, (4) resources, and (5) the use of digital technologies. The main barriers leading to delays in policy development and implementation include (1) insufficient awareness and lack of depression literacy, (2) lack of resources and (3) stigma and social discrimination (4) lack of united action. CONCLUSION: Although the process of implementing a distinctive service programme for depression prevention and treatment in China has been long, the current policy is in line with current global efforts. Strategies to reduce Stigma and increase knowledge about depression are part of a national and international approach to reducing the burden of depression. Political commitment and the involvement of all stakeholders remain necessary. An adequate response to depression will require the involvement of society as a whole, with joint action to reduce the risk of exposure to adversity and enhance protective factors.

Is 3D-printed prosthesis stable and economic enough for anterior spinal column reconstruction after spinal tumor resection? A retrospective comparative study between 3D-printed off-the-shelf prosthesis and titanium mesh cage.

OBJECT: To investigate the stability and cost-effectiveness of the three-dimensional-printed (3DP) off-the-shelf (OTS) prosthesis in the reconstruction of the anterior column of the thoracic/lumbar spine after tumor resection. METHODS: Thirty-five patients (26 with primary malignant tumors and nine with metastatic malignant tumors) who underwent tumor resection and anterior column reconstruction between January 2014 and January 2019 were included in a single institute. Patients were divided into the 3DP OTS prosthesis (3DP) group (n = 14) and the titanium mesh cage (TMC) group (n = 21) by the type of implant. The operation time, intraoperative blood loss, hospital stay, history of radiotherapy, surgical level and total cost were collected and compared between the two groups. Mechanical complications and radiological parameters including mean vertebral height, subsidence, fixation failure(nonunion, migration, screw loosening, rod breakage) rate were recorded at preoperation, 1 week, 3 months, 6 months, 12 months after surgery then at 1 year interval or stop until the end of survival. The follow-up patients were also sent with short form-36 to assess their health-related quality of life (HRQoL) and questions about the current condition of their disease. RESULTS: The mean overall follow-up was 24.6 months. Of the 35 patients involved, six patients died and six were lost to follow-up. The differences between the two groups in operative time, intraoperative blood loss, and hospital stay were not statistically significant (p > 0.05). The differences in fixation failure and the subsidence rate between the two groups were not statistical significant (p > 0.05). The difference of subsidence rate between the cases with and without osteoporosis, cases with and without radiotherapy was statistically significant within each group (p < 0.05). However, the difference of subsidence rate between the surgical level above or below T10 was not statistically significant (p > 0.05). The response rate of the questionnaire among the survived patients was 100% (23/23 patients). The results of the Short Form- (SF-)36 between the two groups were similar (p > 0.05). The total cost was higher in the 3DP group (p < 0.05) with its higher graft cost (p < 0.05), but the differences in internal fixation cost and other cost were not statistically significant between groups (p > 0.05). CONCLUSION: Compared to TMC, the 3DP OTS prosthesis achieved similar clinical and radiological results in spinal anterior spinal column reconstruction of thoracic/lumbar spinal tumor resection. However, the 3DP OTS prosthesis was more expansive than TMC.

Thrombospondin-1 mimic peptide PKHB1 induced endoplasmic reticulum stress-mediated but CD47-independent apoptosis in non-small cell lung cancer.

Non-small cell lung cancer (NSCLC) is one of the most common malignancies with high morbidity and mortality. PKHB1, a serum-stable Thrombospondin-1 (TSP-1) mimic peptide, has shown some effective ability in triggering cell death against several cancers. Here, we aimed to study the potential biological function of PKHB1 and its molecular mechanism in NSCLC. Our results revealed that PKHB1 significantly suppressed NSCLC cell proliferation, cell migration, and induced apoptosis in a dose-dependent manner. Additionally, we found that PKHB1 treatment resulted in mitochondrial transmembrane potential depolarization, Ca2+ overloading as well as the upregulation of proapoptotic proteins. Mechanistically, PKHB1 induced NSCLC cells apoptosis in a CD47-independent manner. Further study revealed that PKHB1 provoked endoplasmic reticulum (ER) stress principally through the activation of CHOP and JNK signaling, which could be alleviated in the presence of 4-PBA, an ER stress inhibitor. Furthermore, xenograft tumor models showed that PKHB1 treatment could notably inhibit NSCLC tumor growth in vivo. In conclusion, these findings suggested that PKHB1 exerted antitumor efficacy in NSCLC via triggering ER stress-mediated but CD47-independent apoptosis, potentially functioned as a promising peptide-based therapeutic agent for NSCLC.

IL-17A contributes to skeletal muscle atrophy in lung cancer-induced cachexia via JAK2/STAT3 pathway.

Cachexia is a complex metabolic syndrome that occurs in approximately 50% of patients with cancer. Skeletal muscle atrophy is the primary clinical feature. Interleukin (IL)-17A, a proinflammatory factor, plays an important role in many chronic inflammatory diseases. Here, we describe a novel signaling pathway through which IL-17A induced muscle atrophy. We conducted a retrospective clinical study to investigate the relationship between IL-17A and the skeletal muscle index in patients with lung adenocarcinoma. We also investigated the involvement of JAK2/STAT3 signaling pathway regarding the main features of cachexia by injecting Lewis lung carcinoma (LLC) cells into C57BL/6 mice as a model to replicate cancer-induced cachexia. In vitro, C2C12 myotubes were treated with recombinant IL-17A, anti-IL-17A monoclonal antibody, STAT3 inhibitor AG490, and LLC-conditioned medium. Cell viability and aging were also evaluated. We found that in cancer conditions, increased serum levels of IL-17A were related to muscle wasting. JAK2/STAT3 phosphorylation was observed in the muscle of LLC tumor-bearing mice, accompanied by decreased MHC/Myog levels and increased MuRF1/Atrogin-1 levels. Administration of anti-IL-17A monoclonal antibody and AG490 slowed muscle atrophy development. Consistent with the in vivo findings, C2C12 myotubes treated with IL-17A and LLC-conditioned medium demonstrated phosphorylated JAK2/STAT3 signaling, resulting in MHC loss and myotube atrophy. IL-17A also inhibited C2C12 cell proliferation, cell cycle breaking, and cellular senescence. Our results identify that phosphorylation of IL-17A/JAK2/STAT3 signaling pathway appears to be an important component in the pathogenesis of LLC tumor-induced cachexia. Targeted therapy of IL-17A may be a promising approach to reduce skeletal muscle loss in patients with cancer.

The relationship between post-traumatic stress and negative emotions in patients with breast cancer: the mediating role of emotion regulation.

Purpose:Negative emotions can adversely affect the treatment and recovery of breast cancer patients. Post-traumatic stress caused by cancer can increase the negative emotions of patients. This study assessed the relationship between post-traumatic stress and emotional regulation strategies, and the role of emotional regulation in the relationship between post-traumatic stress and negative emotions in breast cancer patients.Design:Cross-sectional questionnaire with sample of 214 Chinese women with breast cancerMethods:Participants completed the Impact of Event Scale-Revised, Hospital Anxiety and Depression Scale, and Emotion Regulation Questionnaire. Correlation and mediation analyses were conducted to assess associations among the scores of these scales.Findings:Patients with low post-traumatic stress chose cognitive reappraisal strategies, while those with high post-traumatic stress chose expressive suppression strategies. Cognitive reappraisal had a significant negative predictive effect on negative emotions, while expressive suppression had a significant positive predictive effect on patient's negative emotions.Conclusions:Cognitive reappraisal may reduce the impact of post-traumatic stress on negative emotions experienced by breast cancer patients. Implications for psychosocial providers or policy: Psychosocial workers in China should conduct cognitive reappraisal training for breast cancer patients with high negative emotions and severe post-traumatic stress. For Chinese breast cancer patients living in other regions, the local oncology social workers should take into account their cultural background and lack of expression, and encourage them to choose cognitive reappraisal strategies.

Attentional bias of subliminal emotional faces in adolescents with obsessive-compulsive disorder.

Attentional bias to threatening information may play a vital role in the onset and maintenance of obsessive-compulsive disorder (OCD). This study aimed to explore whether adolescents with OCD exhibited attentional bias toward faces that express disgust or fear. Participants were 27 adolescents with a first-time primary diagnosis of OCD and 27 healthy controls. To assess OCD, depression, and anxiety symptoms, all participants completed the Yale-Brown Obsessive Compulsive Scale, the Hamilton Depression Scale, and the Hamilton Anxiety Scale, respectively, followed by the modified dot probe task. Repeated measures ANOVA revealed a main effect of validity type and a significant group × validity type interaction effect. The results of one sample t-tests showed that participants in the OCD group had an attentional bias toward both disgusted and fearful faces. Further analysis indicated that adolescents in the OCD group showed facilitated attention toward the fearful faces and difficulty disengaging from disgusted faces. Adolescents with OCD exhibited facilitated attention toward threat stimuli, and when they allocated attention to threat, they experienced difficulty disengaging from it. Treatment procedures to modify the attentional bias may be effective.

Dioscin elicits anti-tumour immunity by inhibiting macrophage M2 polarization via JNK and STAT3 pathways in lung cancer.

Tumour-associated macrophage (TAM) is an important component in tumour microenvironment. Generally, TAM exhibits the function of M2-like macrophage, which was closely related to angiogenesis and tumour progression. Dioscin, a natural steroidal saponin, has shown its powerful anti-tumour activity recently. However, the mechanism of dioscin involved in immune regulation is still obscure. Here, we observed dioscin induced macrophage M2-to-M1 phenotype transition in vitro and inhibited IL-10 secretion. Meanwhile, the phagocytosis of macrophages was enhanced. In subcutaneous lung tumour models, dioscin inhibited the augmentation of M2 macrophage populations. Furthermore, dioscin down-regulated STAT3 and JNK signalling pathways in macrophages in vitro. In BMDMs, activating JNK and inhibiting STAT3 induce macrophages to M1 polarization while inhibiting JNK and activating STAT3 to M2 polarization. Additionally, condition mediums from dioscin-pre-treated macrophages inhibited the migration of 3LL cells and the tube-formation capacity of HUVECs. What's more, dioscin-mediated macrophage polarization inhibited the in vivo metastasis of 3LL cells. In conclusion, dioscin may act as a new anti-tumour agent by inhibiting TAMs via JNK and STAT3 pathways in lung cancer.

Finding the silver linings: Psychosocial correlates of posttraumatic growth among husbands of Chinese breast cancer survivors.

OBJECTIVES: Caregiving does not have to be a totally negative experience for the husband caregivers of breast cancer survivors (BCS). There are growing interests in exploring the positive psychological changes (aka posttraumatic growth; PTG) among husbands of BCS. Western studies have shown that coping resources, cognitive appraisal, and coping strategies are associated with PTG among caregivers of BCS. Studies in the Chinese context are limited. This study examined the psychosocial correlates of PTG among husbands of Chinese BCS. METHODS: Husbands of Chinese BCS (N = 176) were recruited from two hospitals in Weifang, China to complete a cross-sectional survey. Their levels of caregiving burden, marital satisfaction, cognitive appraisals, coping strategies, and PTG were measured. RESULTS: After controlling for covariates, hierarchical regression results indicated that higher caregiving burden (ß = .29), marital satisfaction (ß = .27), challenge appraisal (ß = 016), and social support seeking (ß = .23) were associated with higher PTG (Ps < .05). Additionally, a significant interaction between caregiving burden and positive reframing emerged in explaining PTG (ß = .17, P < .05). Positive reframing was only associated with higher PTG among those with higher caregiving burden (ß = .25, P = .03), but not those with lower caregiving burden (ß = -.09, P > .05). CONCLUSIONS: Stress and coping variables significantly contributed to PTG among husbands of Chinese BCS. Our findings implied that addressing those husband caregivers' marital satisfaction, challenge appraisal toward the impact of breast cancer, and social support seeking could be intervention strategies to facilitate their PTG. Among husbands having higher caregiving burden, positive reframing may also facilitate their PTG.

Treatment decision-making, family influences, and cultural influences of Chinese breast cancer survivors: a qualitative study using an expressive writing method.

PURPOSE: Among Chinese breast cancer survivors, treatment decision-making is different than that in western countries. Among Chinese women, family often plays an important role during the treatment period, and Chinese-specific cultural factors have negative influences on their psychological conditions. The aim of the present study was to explore the treatment decision making, family influences, and cultural influences of Chinese breast cancer survivors. METHODS: This study used an expressive writing method to explore the experiences of breast cancer survivors who were diagnosed with stage 0 to III cancer. Participants were instructed to write 30 min per week over a period of 3 weeks. All writings were analyzed using a qualitative method. RESULTS: Three themes were identified: treatment decision making, family influences, and cultural influences. Treatment decision-making included the subthemes of preference for mastectomy, passive involvement, and active involvement. Family influences included the subthemes of financial burden, family expectations, and family support. Cultural influences included the subthemes of fatalism, barriers to expressing emotions, and stigma related to cancer. CONCLUSIONS: Information on breast cancer treatment and survivorship should be provided to patients through multiple methods to improve their knowledge of breast cancer. Family support should be maintained to ensure patients' confidence and courage during the treatment period. Necessary and appropriate psychological interventions that consider cultural influences should be administered.

Caregiving burden and self-efficacy mediate the association between individual characteristics and depressive symptoms among husbands of Chinese breast cancer patients.

PURPOSE: Perceptions of caregiving burden and self-efficacy are found to be associated with well-being among husbands of breast cancer patients (BCP). However, little is known about how individual characteristics associate with such caregiving-related perceptions and cancer caregivers' well-being. This study examined the associations between two individual characteristics (male gender role norms and ambivalence over emotional expression (AEE)) and depressive symptoms among husbands of Chinese BCP, and the potential mediating roles of caregiving burden and self-efficacy in such associations. METHODS: Participants (n = 176) were recruited in two hospitals in Weifang, China. Their endorsement of male gender role norms (e.g., "men should not ask for help"), AEE, caregiving burden, and depressive symptoms were measured in a cross-sectional survey. RESULTS: Path analysis results supported the proposed mediation model with satisfactory fit indices (χ2(2) = 2.73, p = .26, CFI = 1.00; IFI = 1.00; RMSEA = 0.05). Specifically, male gender role norms and AEE were associated with higher caregiving burden and lower caregiving self-efficacy, which in turn were associated with more depressive symptoms. Bootstrapping results supported that both male gender role norms (ß = 0.16; 95%CI = 0.09, 0.25) and AEE had significant indirect effects on depressive symptoms (ß = 0.11; 95%CI = 0.04, 0.18) via caregiving burden and self-efficacy, indicating that caregiving-related perceptions could mediate between individual characteristics and depressive symptoms. CONCLUSIONS: Male gender role norms and AEE might affect depressive symptoms among husbands of Chinese BCP through caregiving-related perceptions. Future interventions that reduce those husbands' barriers to express emotions, appreciate their commitment to take good care of their spouses, enhance caregiving skills, and reduce caregiving burden may decrease their depressive symptoms.

Associations between physical activity, sedentary behaviour and self-rated health among the general population of children and adolescents: a systematic review and meta-analysis.

BACKGROUND: Self-rated health (SRH) is an indicator that captures a person's perception of their overall health status. The relationship between physical activity (PA), sedentary behaviour (SB) and SRH has been investigated in systematic reviews among adult and elderly populations. No systematic review to date has synthesized the relationship between PA, SB and SRH among children and adolescents. The purpose of this systematic review and meta-analysis was to synthesize the associations between PA, SB and SRH in the general population of children and adolescents and to investigate the dose-response relationship between PA, SB and SRH. METHODS: We conducted a computer search for English language studies in the databases of MEDLINE, EMBASE and PSYCINFO that were published between 1946 and 2019. We searched PubMed, Google Scholar, and the references of the identified publications for additional studies. A meta-analysis was employed to synthesize the associations between PA, SB respectively and SRH. The dose-response association was tested using a random effects meta-regression model. The review was reported following the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. RESULTS: Sixty-eight published articles were included in the final review, including 59 cross-sectional and nine longitudinal studies. We found evidence that PA was associated with better SRH, and SB was associated with lower SRH among children and adolescents. A dose-response relationship between PA and SRH was observed, where a higher level of PA was associated with better SRH than a lower level of PA. The relationship between PA, SB and SRH was observed in both boys and girls, and did not show a significant gender difference. CONCLUSIONS: The findings in the systematic review suggest that health intervention programmes targeting promoting PA and reducing SB among children and adolescents may enhance their overall health status. Future research is needed to expand prospective cohort and intervention studies to address directionality and causality in the relationships between PA, SB and SRH among children and youth.

The benefits of expressive writing among newly diagnosed mainland Chinese breast cancer patients.

The study aimed to evaluate the effects of an expressive writing intervention on quality of life (QoL) among mainland Chinese breast cancer patients. A total of 118 Chinese breast cancer patients were randomly assigned to one of four groups: a cancer-facts writing condition (CTL group), an emotional disclosure writing condition (EMO group), a self-regulation writing condition (SR group), or a neutral control condition with no writing tasks (CON group). QoL was assessed by FACT-B at baseline, 3-, and 6-month follow-ups. A repeated measure analysis of variance revealed significant effects of time (F = 13.9, P < 0.001, η2 = 0.20) and the time × group interaction (F = 3.5, P < 0.01, η2 = 0.08) on QoL. Residualized change models showed that the CTL, EMO and SR groups reported higher levels of QoL than the CON group at the 6-month follow-up. The EMO group had a higher level of QoL than the SR group. The CTL group had higher level of physical well-being compared to the SR group. Mainland Chinese breast cancer patients shortly after diagnosis benefit from expressive writing. They benefited more from cancer-facts and emotional disclosure compared to self-regulation. The study indicated that the impact of expressive writing may differ due to stage of cancer survivorship, social, and cultural context.
