The effectiveness of compassion-based interventions among cancer patients: A systematic review and meta-analysis.

OBJECTIVES: This study examined the effects of compassion-based intervention on mental health in cancer patients by using systematic review and meta-analysis of randomized controlled trials (RCTs). METHODS: Eleven bibliographic databases were searched from their earliest data available date up to March 1, 2022. The databases were PubMed, CINAHL, MEDLINE, PsycINFO, WOS, Cochrane, Embase, Scopus, ProQuest Dissertations, Airiti Library, and the National Digital Library of Theses and Dissertations in Taiwan. RESULTS: Ten studies from 2015 to 2021 were included with a total of 771 cancer patients. Most were targeted at women with breast cancer. Brief compassion-based interventions of approximately 30 minutes were conducted by audio file, paper, and web-based self-guided writing prompts. Most were conducted after the completion of active treatment. Anxiety was the most measured outcome. Constructive compassion-based interventions with 4- to 12-week sessions were conducted by a trained facilitator. Most were conducted for patients who had undergone treatment, and depression was the most measured outcome. The meta-analysis indicated that compassion-based interventions had a significant effect of reducing depression and increasing self-compassion. Moderation analysis indicated that constructive intervention showed more benefits of increased self-compassion than brief intervention. Both face-to-face and non-face-to-face web-delivered formats had benefits for increasing self-compassion compared with the control condition. SIGNIFICANCE OF RESULTS: Compassion-based interventions might provide an effective strategy for improving self-compassion and depression among patients with breast cancer. Suggestions for further research and health-care providers follow.

Ameliorative Effect of Imperatorin on Dermatophagoides pteronyssinus-Induced Allergic Asthma by Suppressing the Th2 Response in Mice.

Imperatorin is a furanocoumarin derivative and an effective ingredient in several Chinese medicinal herbs. It has favorable expectorant, analgesic, and anti-inflammatory effects. In this study, we investigated whether imperatorin has protective effects against Dermatophagoides pteronyssinus (Der p)-induced asthma in mice. Lung and bronchial tissues were histopathologically examined through hematoxylin-eosin staining. The concentrations of immunoglobin E (IgE), IgG1, IgG2a in serum and those of T helper 1 (Th1) and two cytokines and eosinophil-activated chemokines in bronchoalveolar lavage fluid (BALF) were detected using an enzyme immunoassay. Histological examination revealed that imperatorin reduced inflammatory cell infiltration, mucus hypersecretion, and endothelial cell hyperplasia. The examination also indicated that imperatorin could reduce the inflammatory cell count in BALF as well as IgE and IgG1 expression in serum, but IgG2a expression was significantly increased. Imperatorin reduced the production of interleukin (IL)-4, IL-5, and IL-13 by Th2, promoted the production of interferon-γ and IL-12 by Th1, and increased the production of IL-10 in bronchoalveolar lavage fluid. These findings suggest that imperatorin has a considerable anti-inflammatory effect on Der p-induced allergic asthma in mice.

Macrophage Distribution Affected by Virus-Encoded Granulocyte Macrophage Colony Stimulating Factor Combined with Lactate Oxidase.

Oncolytic virotherapy was approved as a localized treatment for advanced melanoma by the US Food and Drug Administration (FDA) in 2015. Granulocyte macrophage colony stimulating factor (GM-CSF) encoded by clinical virus-infected tumor cells, acting as a pro-inflammatory cytokine or growth factor, increases tumor antigen presentation, leading to the activation of macrophages and T cells. Notably, tumor-secreted lactate can promote the suppressive functions of M2-polarized tumor-associated macrophages and subsequently promote tumor growth. Furthermore, the consumption of tumor-secreted lactate has been implicated in the beneficial polarization of macrophages. Here, we report that GM-CSF-encoded recombinant adeno-associated virus (AAV2-GM-CSF) infection in B16-F10 mouse melanoma cells combined with lactate oxidase (LOX) leads to the recruitment of M1 macrophages for the inhibition of cancer cell growth. This study suggests that GM-CSF combined with LOX has potential as cancer virotherapy.

The effects of an emergency nurse-led stress-reduction project during the first 120 days of the COVID-19 pandemic in Taiwan.

BACKGROUND: The COVID-19 frontline nurses' stress-reduction programme by the cooperation of manager with the nurses is not-well developed. AIM: This study aimed to examine the effect of an emergency nurse-led stress-reduction project on reducing stress levels during the COVID-19 pandemic. METHODS: The action research was conducted using online and person-to-person group brainstorming strategies. The online survey was used to evaluate emergency nurses' stress levels, causes of stress and needs at the 50th, 80th and 110th days of the pandemic from March to May 2020. RESULTS: The numbers of nurses participating in three-time survey were 160, 166 and 160, respectively. There was a decrease in the nurses' work-related stress after implementing the improvement strategies. Stress from personal protective equipment (PPE), information about infection control and family's worry about being infected reduced across 2 months. Needs regarding PPE, COVID-19 information and a forum for sharing experiences of COVID-19 care decreased whereas needs of allowing more days off increased. CONCLUSIONS: The stress-reduction project targeting at nurses' views of their needs can reduce their stress during the COVID-19 pandemic. IMPLICATIONS FOR NURSING MANAGEMENT: The online and person-to-person group brainstorming building a good partnership between nurses and managers can be an effective nursing management.

Synergistic Effect of Repolarization of M2 to M1 Macrophages Induced by Iron Oxide Nanoparticles Combined with Lactate Oxidase.

Metabolic reprogramming of tumors with the accompanying reprogramming of glucose metabolism and production of lactate accumulation is required for the subsequent development of tumors. Recent evidence has indicated that tumor-secreted lactate can promote an oncolytic immune microenvironment within the tumor. Furthermore, tumor-secreted lactate directly induces polarization of tumor-supportive M2 macrophages. However, oxidized tumor-secreted lactate in the tumor microenvironment can be exploited. Iron oxide nanoparticles have shown promising anticancer potential by activating tumor-suppressing macrophages. Furthermore, lactate oxidase (LOX) generally oxidizes tumor-secreted lactate and subsequently converts to pyruvate. Particularly, the ratio of M2 macrophages to M1 macrophages corresponds with tumor growth. In this study, we present iron oxide nanoparticles with carboxylic acid combined with LOX that enhance antitumor efficacy as a synergistic effect on the repolarization of tumor-supportive M2 macrophages to tumor-suppressive M1 macrophages in a tumor microenvironment. After M2 macrophages treated with iron oxide nanoparticles were combined with LOX, the ratio of M1 macrophages was significantly greater than iron oxide nanoparticles alone or with LOX alone. It is concluded that the inhibition of cancer cell proliferation by ratio of M1 macrophages was observed. This study suggests that the iron oxide nanoparticles combined with LOX could be potentially used for potentiating immune checkpoint inhibitor therapies for cancer treatment.

Bone Marrow Hypocellularity in Patients with End-Stage Kidney Disease.

BACKGROUND: Anemia and pancytopenia are not uncommon in patients with chronic kidney disease (CKD). Nevertheless, there is insufficient literature analyzing bone marrow pathology in patients with CKD or end-stage kidney disease (ESKD) receiving dialysis. METHODS: This observational cohort study included 22 patients with ESKD and 23 patients with CKD that received bone marrow biopsy and aspiration at Chang Gung Memorial Hospital. Demographic, hematological, and biochemical data were collected at the time of bone marrow study for analysis. RESULTS: Bone marrow aspiration demonstrated that patients with ESKD had a lower percentage of blasts than patients with CKD (0.52 ± 0.84 versus 1.06 ± 0.78 %, p = 0.033). Bone marrow biopsy revealed that the overall incidence of hypocellular bone marrow was 55.6%. Furthermore, patients with ESKD had higher proportion of hypocellular bone marrow than patients with CKD (72.7% versus 39.1%, p = 0.023). In a multivariate logistic regression model, it was revealed that ESKD status (odds ratio 9.43, 95% confidence interval 1.66-53.63, p = 0.011) and megakaryocyte count within bone marrow (odds ratio 0.48, 95% confidence interval 0.29-0.79, p = 0.004) were significant predictors for bone marrow hypocellularity. CONCLUSION: Bone marrow hypocellularity is common in patients with kidney dysfunction. Hypocellular marrow occurs more frequently in patients with ESKD than patients with CKD.

Potential therapeutics using tumor-secreted lactate in nonsmall cell lung cancer.

Targeted-therapy failure in treating nonsmall cell lung cancer (NSCLC) frequently occurs because of the emergence of drug resistance and genetic mutations. The same mutations also result in aerobic glycolysis, which further antagonizes outcomes by localized increases in lactate, an immune suppressor. Recent evidence indicates that enzymatic lowering of lactate can promote an oncolytic immune microenvironment within the tumour. Here, we review factors relating to lactate expression in NSCLC and the utility of lactate oxidase (LOX) for governing therapeutic delivery, its role in lactate oxidation and turnover, and relationships between lactate depletion and immune cell populations. The lactate-rich characteristic of NSCLC provides an exploitable property to potentially improve NSCLC outcomes and design new therapeutic strategies to integrate with conventional therapies.

The Short- and Long-term Causal Relationships Between Self-compassion, Trait Mindfulness, Caregiver Stress, and Depressive Symptoms in Family Caregivers of Patients with Lung Cancer.

OBJECTIVES: Using a prospective longitudinal design, this paper examines a serial mediation model of the associations between self-compassion, trait mindfulness, caregiver stress, and depressive symptoms among the family caregivers of patients with lung cancer. METHODS: A four-wave design was used, with initial assessment (T1) and three follow-ups, at the 2nd month (T2), the 5th month (T3), and the 8th month (T4). A total of 123 family caregivers completed the baseline measurements, including caregiver stress, self-compassion, trait mindfulness, and depressive symptoms. Data were analyzed by serial mediation models to determine the causal ordering of these variables. RESULTS: Nearly one-quarter of the family caregivers suffered from clinically significant depressive symptoms and the severity of their depression remained unchanged throughout the 8-month follow-up period. Both cross-sectional and longitudinal path analyses revealed that the relationship between self-compassion and depressive symptoms was mediated sequentially by trait mindfulness and caregiver stress. The subscale analysis indicated that the association of higher compassionate action with fewer depressive symptoms was through chain-mediating effects of higher mindful awareness and lower caregiver stress. CONCLUSIONS: Family caregivers who have higher levels of self-compassion tend to have more mindfulness; greater mindfulness leads to lower levels of perceived caregiving stress which, in turn, links to fewer symptoms of depression. Both self-compassion and mindfulness could be regarded as protective factors for caregivers to reduce caregiving stress and depression.

Trait mindfulness and depressive symptoms in non-small cell lung cancer patients: the mediating roles of quality of life and meaning in life.

OBJECTIVE: The present study examined the potential mediating influences of meaning in life and quality of life in the relationship of trait mindfulness and depressive symptoms in lung cancer patients. Design: We adopted a cross-sectional design studying a sample of patients with non-small cell lung cancer, aged 20-65 years, and receiving cancer treatments or follow-up care. Main Outcome Measures: The outcome measures included Beck Depression Inventory-II, European Organisation for Research and Treatment of Cancer Core Cancer Quality of Life Questionnaire (EORTC QLQ-C30) and lung cancer specific complementary measure (EORTC QLQ-LC13), Five Facet Mindfulness Questionnaire, and the meaning in life questionnaire. Results: Among 116 lung cancer patients, 26.72% of them had clinically significant depressive symptoms. The presence of meaning, quality of life (QOL) functioning and symptom distress mediated the relationship of trait mindfulness and depressive symptoms. Multiple mediation analyses found that the presence of meaning in life was the main mediator. Conclusion: The reductions of depressive symptoms might be related to trait mindfulness enhancing lung cancer patients' perceptions of meaning in life. A mindfulness program has the potential to improve depressive symptoms in people with lung cancer.

Effects of workplaces receiving "accreditation of health workplaces" on breastfeeding promotion, parental leave, and gender equality.

OBJECTIVES: Work is often a barrier for women to continue breastfeeding after they have given birth. Breastfeeding support is an important part of workplace health promotion. We investigated the implementation of breastfeeding promotion and gender equality polices in workplaces with the Taiwan Badge of Accredited Healthy Workplace. METHODS: Our samples consisted of 1648 corporations with the badge of Accredited Healthy Workplace issued by the Bureau of Health Promotion from 2007 to 2008. Concomitantly, 2000 corporations without accreditation were randomly selected from the National Business Directory as the control group. Data were collected from self-administered questionnaires. Logistic regression was used to examine the association with breast-feeding promotion and other variables in Taiwanese workplaces. RESULTS: Members of accredited group of 1089/1648 (66.1%) and the control group of 526/2000 (26.3%) responded to the questionnaire. The accredited companies had more mother-friendly settings, including breastfeeding policies and documents, appropriate breastmilk preserving equipment and settings in the workplace. In the accredited group, breastfeeding rate of mothers returning to work after giving birth was 64.3% in 2008 (1 year after giving birth) and 60.4% in 2009 (1 year after giving birth), while the rate of the control group was 59.1% in 2008 and 51% in 2009. CONCLUSION: Accredited corporations are better at breastfeeding support than those of the control group. This might be related to the company size, location, and the implementation of tobacco control and/or occupational health promotion policies, which may increase awareness of healthy workplaces and influence maternal protection positively.

Comparing the Protection Imparted by Different Fraction Extracts of Garlic (Allium sativum L.) against Der p-Induced Allergic Airway Inflammation in Mice.

Garlic (Allium sativum L.) has been used extensively as a food ingredient and medicinally, but the effect on asthmatic airway inflammation has not been studied in detail. We accordingly explored the protective effects exerted by various garlic fraction extracts against airway inflammation with Dermatophagoides pteronyssinus (Der p)-induced allergic asthma in vivo and in vitro. Garlic extraction was realized using n-hexane, dichloromethane, ethylacetate, n-butanol, and water in sequence to obtain different fraction extracts. Mice were orally administered different fractions (80 mg/kg) daily for four weeks. The histological results showed that the water fraction could ameliorate lung-based goblet cell hyperplasia, inflammatory cell infiltration, and mucus hypersecretion. The water fraction extracts decreased IgE and IgG1, and they decreased inflammatory cells as quantified in bronchoalveolar lavage fluid (BALF); however, they increased IgG2a in serum. Moreover, the water fraction extracts increased IFN-γ and IL-12 (both constituting Th1 cytokines) in BALF, but they reduced IL-13, -4, and -5 (all constituting Th2 cytokines), and also inhibited the expression of IL-1ß, IL-6, and TNF-α. The water fraction also inhibited the PI3K/Akt/NF-κB signal pathways in A549 cells. These findings suggest that water fraction extracts of garlic have a clear anti-inflammatory effect on Der p-induced allergic asthma.

The Protective Role of Garlic on Allergen-Induced Airway Inflammation in Mice.

Asthma is the most prevalent chronic respiratory disease worldwide. Garlic extracts have long been used as a food source and in traditional medicine. Crude extracts of garlic are used as an anti-inflammatory agent and have been reported to exhibit antiasthmatic properties. However, molecular mechanisms of garlic extracts in the context of antiasthmatic airway inflammation are still unclear. In this study, the antiasthmatic effect of garlic extracts on Th1, Th2, and Th3 cytokine profiles and immunoregulatory mechanism were explored using an animal model of allergic asthma. Garlic extracts significantly reduced total inflammatory cell counts and eosinophil infiltration and decreased the production of Dermatophagoides pteronyssinus IgE in serum and Th1/Th2/Th3 cytokine in bronchoalveolar fluid. Enzyme-linked immunosorbent assay analysis demonstrated that garlic extracts downregulated the levels of cytokines and chemokines, namely Th2-related IL-4, IL-5, and IL-13; but they simultaneously upregulated Th1-related IFN-γ, IL-12, and Th3-related IL-10 and TGF-ß expression in BALF. The mechanism may be ascribed to the modulation of Th1-, Th2-, and Th3-related cytokine imbalance.

Dispositional mindfulness, self-compassion, and compassion from others as moderators between stress and depression in caregivers of patients with lung cancer.

OBJECTIVE: The present study aimed to identify the most important protective factors predicting caregivers' depressive symptoms among factors of caregivers' dispositional mindfulness, self-compassion, compassion from others, and patients' dispositional mindfulness and their moderator effects on the relationship between caregiving stress and depressive symptoms. METHODS: A total of 72 lung cancer outpatients and their family caregivers participated in this study. Family caregivers completed the Kingston Caregiver Stress Scale, Beck Depression Inventory-II (BDI-II), Five Facet Mindfulness Questionnaire (FFMQ), Self-Compassion Scale, and Compassion from Others Scale. Patients completed the EORTC Quality of Life Questionnaire Core 30 (EORTC QLQ-C30), BDI-II, and FFMQ. RESULTS: After controlling for patients' factors (treatment status, symptom distress, and depressive symptoms) and caregivers' health status, caregivers' stress and dispositional mindfulness, the domain of mindful awareness, and self-compassionate action were significantly associated with their depressive symptoms. Further analysis indicated that mindful awareness or self-compassionate action could buffer the effect of caregiving stress on depressive symptoms. When the two moderators, mindful awareness and self-compassionate action, were tested simultaneously, only self-compassionate action remained as a significant moderating effect. CONCLUSIONS: Caregivers' mindful awareness and self-compassionate action were protective factors, which mitigate the impact of caregiving stress on their depressive symptoms. Therefore, the future supportive program aims at training the competencies of self-compassionate action with mindful awareness, which may enhance caregivers' coping resources.

The effects of supportive care interventions on depressive symptoms among patients with lung cancer: A metaanalysis of randomized controlled studies.

OBJECTIVE: Our aim was to examine the effect of supportive care interventions on depressive symptoms in patients with lung cancer. METHOD: We searched the databases of the Cochrane Central Register of Controlled Trials (CENTRAL), Ovid EMBASE, PubMed, and the Chinese Electronic Periodical Services (CEPS) from their inception until September of 2015. We included randomized controlled trial studies that compared standard care with supportive care interventions. The standardized mean difference (SMD) (Cohen's d) was calculated to estimate the effect of interventions. Subgroup analysis was conducted to identify possible sources of heterogeneity. RESULTS: A total of 1,472 patients with lung cancer were identified. Compared with standard care, the overall effects of all supportive care interventions significantly reduced depressive symptoms (SMD = -0.74, CI 95% = -1.07 to -0.41), and the effects could be maintained at weeks 4, 8, and 12 of follow-up. Three types of supportive care interventions were identified: psychotherapy combined with psychoeducation, psychoeducation alone, and an exercise program. Both psychotherapy combined with psychoeducation and exercise significantly improved depressive symptoms, while psychoeducation alone did not yield significant effects. The moderating effects indicated that greater improvements in depressive symptoms were found in lung cancer patients with a severe level of depressive symptoms at baseline. SIGNIFICANCE OF RESULTS: Personalized supportive care interventions can be developed based on the main causes of depressive symptoms. Psychotherapy combined with psychoeducation can target the causes of depressive symptoms, including both physical distress and psychological trauma due to lung cancer, while exercise programs can effectively improve depressive symptoms for lung cancer patients with impaired respiratory function.

The correlations of sexual activity, sleep problems, emotional distress, attachment styles with quality of life: comparison between gynaecological cancer survivors and noncancer women.

AIMS AND OBJECTIVES: To compare quality of life and its related factors, which include sexual activity, sleep problems, depression, anxiety and attachment styles in close relationships, between gynaecological cancer survivors and noncancer women. BACKGROUND: The majority of studies focus on examining the relationships between the late-treatment side effects and quality of life in gynaecological cancer survivors. As a result, there is insufficient information about what are the correlations between psychosocial factors and quality of life in gynaecological cancer survivors. DESIGN: Cross-sectional study. METHODS: The quality of life of the 85 gynaecological cancer patients who had completed active treatments for at least six months was compared with the 85 age-matched women without cancer history. Measures included SF-12 Health Surveys, Medical Outcomes Study Sleep Scale, Beck Depression Inventory-II, State-Trait Anxiety Inventory, Sexual Activity Questionnaire and Experiences in Close Relationships-Revised. RESULTS: There were no significant differences in the quality of life between gynaecological cancer survivors and noncancer women. However, higher attachment-related anxiety in close relationship was the main factor associated with the lower physical quality of life in the gynaecological cancer survivor group. In contrast, older ages were correlated with lower physical quality of life in noncancer women. Anxiety level was the main factor associated with lower mental quality of life for both groups. CONCLUSIONS: Different from noncancer women, the psychosocial factor of insecure attachment in close relationships was the main factor associated with physical quality of life for gynaecological cancer survivors. Anxiety status was the common factor correlated with mental quality of life for cancer and noncancer women. RELEVANCE TO CLINICAL PRACTICE: Developing psychosocial interventions focusing on secure attachment in close relationships and anxiety management could improve physical and mental components of quality of life among gynaecological cancer survivors.

Seasonal distribution of pacemaker implantation for symptomatic bradycardia.

Permanent cardiac-pacemaker therapy is widely recognized as beneficial in the treatment of various types of symptomatic bradycardia. However, the seasonal distribution of pacemaker implantation has never been discussed. The purpose of this study was to investigate the seasonal distribution of pacemaker implantation in a large population of patients with symptomatic bradycardia. The study population consisted of 904 patients who underwent implantation of a new permanent pacemaker between January 1999 and December 2001 and were registered in the database of CPI Company in Taiwan. The number of pacemaker implantations in each month was analyzed to investigate the seasonal distribution of pacemaker implantations in a year. The number of patients who underwent pacemaker implantation between October and December was significantly higher than that of other seasons (P < 0.007). The results indicate that there is a tendency for bradyarrhythmic patients to have symptoms between October and December.
