Immediate impact of Mindfulness-Based Cognitive Therapy (MBCT) among women with breast cancer: a systematic review and meta-analysis.

BACKGROUND: Mindfulness-based cognitive therapy (MBCT) may have positive physiological and psychological benefits for breast cancer survivors. However, few studies involved a combination of the relevant literatures to confirm the effects. METHODS: Our study included randomized controlled trials (RCTs) and non-RCTs comparing interventions of MBCT and control protocols for alleviation of symptoms among breast cancer survivors. We calculated pooled mean differences (MDs), standardized mean differences (SMDs), and 95% confidence intervals (CIs) by using random effects models to estimate summary effect sizes. RESULTS: Thirteen trials with 20-245 participants were considered in our studies; for the meta-analysis, 11 of these studies were eligible for assessment. The pooled meta-analysis results revealed that at the end of the MBCT intervention, participants' anxiety (SMD, - 0.70; 95% CI, - 1.26 to - 0.13; I2 = 69%), pain (SMD, - 0.64; 95% CI, - 0.92 to - 0.37; I2 = 0%), and depression (SMD, - 0.65; 95% CI, - 1.14 to - 0.17; I2 = 75%) levels significantly decreased, and their mindfulness (MD, 8.83; 95% CI, 3.88 to 13.78; I2 = 68%) levels significantly increased. CONCLUSION: The MBCT may be associated with improved pain, anxiety, depression, and mindfulness. However, the quantitative analysis pointed to an inconclusive result due to moderate to high levels of heterogeneity among indicator of anxiety, depression, and mindfulness. Future work requires more studies to better elucidate the clinical significance of this possible association. The results suggest that MBCT is highly beneficial as an intervention for patients who have received treatment for breast cancer.

Impact of mindfulness-based stress reduction on female sexual function and mental health in patients with breast cancer.

PURPOSE: There have been few studies using mindfulness-based stress reduction (MBSR) to improve sexual function in Asian women with breast cancer. This study aimed to evaluate the impact of mindfulness intervention on female sexual function, mental health, and quality of life in patients with breast cancer. METHODS: Fifty-one women with breast cancer were allocated into 6-week MBSR (n=26) sessions or usual care (n=25), without differences in group characteristics. The research tools included the Female Sexual Function Index (FSFI), the Depression Anxiety Stress Scales-21 (DASS-21), and the EuroQol instrument (EQ-5D). The Greene Climacteric Scale (GCS) was used to verify the foregoing scale. The effects of MBSR were evaluated by the differences between the post- and pre-intervention scores in each scale. Statistical analyses consisted of the descriptive dataset and Mann-Whitney ranked-pairs test. RESULTS: Although MBSR did not significantly improve sexual desire and depression in patients with breast cancer, MBSR could improve parts of female sexual function [i.e., Δarousal: 5.73 vs. -5.96, Δlubrication: 3.35 vs. -3.48, and Δsatisfaction: 8.48 vs. 1.76; all p <.005], with a range from small to medium effect sizes. A significantly benefits were found on mental health [Δanxiety: -10.92 vs.11.36 and Δstress: -10.96 vs.11.40; both p <.001], with large effect sizes, ranging from 0.75 to 0.87. CONCLUSION: Our study revealed that MBSR can improve female sexual function and mental health except for sexual desire and depression in women with breast cancer. Medical staff can incorporate MBSR into clinical health education for patients with breast cancer to promote their overall quality of life.

Naringenin inhibited migration and invasion of glioblastoma cells through multiple mechanisms.

Glioblastoma (GBM) is the most mortality brain cancer in the world. Due to high invasion and drug resistance cause the poor prognosis of GBM. Naringenin, an ingredient of citrus, exhibits many cellular functions such as antioxidant, anti-inflammation, and anticancer. Naringenin inhibits the migration of bladder and lung cancer via modulation of MMP-2 and/or MMP-9 activities, Naringenin inhibits migration and trigger apoptosis in gastric cancer cells through downregulation of AKT pathway. However, the effects of naringenin in GBM still remain to be elucidated. In this study, we reveal the molecular mechanisms of naringenin in the inhibition of migration and invasion in GBM. No overt alternation of cell proliferation was found in of GBM 8901 cells treated with different concentration of naringenin. Slight decreased cell viability was found in GBM 8401 cell treated with 200 and 300 µM naringenin. Significant reduction of migration and invasion as assayed by Boyden chamber analysis was found in of GBM cells treated with 100, 200, and 300 µM naringenin. Zymography analysis also revealed that the activities of MMP-2 and MMP-9 of GBM cells were significantly inhibited in response to 100, 200, or 300 µM naringenin treatment. Proteins of MMP-2 and MMP-9 were downregulated in naringenin treated GBM cells. In addition, naringenin also attenuated the activities of ERK and p38. Naringenin decreased mesenchymal markers (snail and slug) expression as revealed by Western blot analysis. Taken together, our findings indicated that naringenin eliminated the migration and invasion of GBM cells through multiple mechanisms including inhibition of MMPs, ERK, and p38 activities and modulation of EMT markers. Our results also suggested that naringenin may be a potential agent to prevent metastasis of GBM.

The Comparative Effect of Reduced Mindfulness-Based Stress on Heart Rate Variability among Patients with Breast Cancer.

Heart rate variability (HRV) is a powerful tool for observing interactions between the sympathetic and parasympathetic nervous systems. This study evaluated HRV during a mindfulness-based stress reduction (MBSR) program among women with breast cancer after receiving treatment. A quasi-experimental, nonrandomized design was used. Patients were allocated to usual care (n = 25) and MBSR (n = 25) groups. HRV was measured using recognized methods to assess the autonomic nervous system. Two-way ANOVA and t-tests were used to examine HRV changes between and within groups, respectively. A significant interaction effect of time with group was observed on heart rate (F (1, 96) = 4.92, p = 0.029, η2 = 0.049). A significant difference was also observed within the MBSR group preintervention and postintervention with regard to heart rate (t (24) = −3.80, p = 0.001), standard deviation of the RR interval (t (24) = 5.40, p < 0.001), root-mean-square difference in the RR interval (t (24) = 2.23, p = 0.035), and high-frequency power (t (24) = 7.73, p < 0.001). Large effect sizes for heart rate and SDNN of 0.94 and 0.85, respectively, were observed between the MBSR and usual care groups. This study provides preliminary evidence that an MBSR program may be clinically useful for facilitating parasympathetic activity associated with feelings of relaxation in treated breast cancer survivors.

Cognitive-Behavioral Therapy to Alleviate Treatment-Induced Menopausal Symptoms in Women With Breast Cancer: A Systematic Review.

BACKGROUND: Numerous women with breast cancer (BC) exhibit early menopausal symptoms after undergoing cancer treatments. Medications that control menopausal symptoms can cause severe side effects and are contraindicated for patients with BC. Therefore, complementary and alternative medicines should be used. This study investigates the use of cognitive-behavioral therapy (CBT) for patients with menopausal symptoms after BC treatment. OBJECTIVE: A systematic review was conducted to determine the efficacy and availability of CBT interventions in reducing treatment-induced menopausal symptoms in female patients with BC. METHODS: Keywords were searched in Medical Subject Headings and 5 databases. The search criteria included randomized controlled trials (RCTs), non-RCTs, and single-group pre- and post-studies. Because of the risk of bias in non-RCTs using Joanna Briggs Institute's critical appraisal tools and single-group studies, the Critical Appraisal Skills Programme checklist for qualitative studies and RCTs was appraised using the Jadad scale. RESULTS: After the review, 9 suitable studies were identified. Standard CBT programs lasted for 6 consecutive weeks, with 1 session of 1.5 hours weekly. The follow-up time was approximately 9 to 26 weeks. Women receiving CBT exhibited improvement in physical function and psychological state. This review supported the use of CBT to effectively improve the mental health of and reduce treatment-induced menopausal symptoms in BC survivors. CONCLUSIONS: Cognitive-behavioral therapy interventions yielded positive outcomes in patients with BC, particularly in those experiencing menopausal symptoms. IMPLICATIONS FOR PRACTICE: Cancer treatment generated severe menopausal symptoms in patients with BC. However, health professionals may use CBT to alleviate patients' menopausal symptoms.

Short-term Effects of Randomized Mindfulness-Based Intervention in Female Breast Cancer Survivors: A Systematic Review and Meta-analysis.

BACKGROUND: Patients with breast cancer usually experience depression, anxiety, stress, fatigue, pain, poor sleep quality, and low quality of life after their cancer treatment. Some studies used mindfulness-based stress reduction (MBSR) interventions for reducing these symptoms; however, the results are conflicting. OBJECTIVE: This study evaluated the clinical efficacy of MBSR interventions in the short term. METHODS: Five databases were searched from their inception to April 2020. We included only randomized controlled trials (RCTs) comparing MBSR intervention and control groups for symptom reduction in women with breast cancer. Pooled mean difference (MD), standardized MD, and 95% confidence intervals (CIs) were calculated using random-effects models. We used the Cochrane risk-of-bias assessment tool to assess the included RCTs. RESULTS: Nineteen RCTs with 36 to 336 participants were included, of which 11 studies with a total of 1687 participants (mean age, 53.3 years) were eligible for the meta-analysis. The pooled meta-analysis results indicated that, at the end of the MBSR interventions, participants' depression (standardized MD, -1.32; 95% CI, -2.18 to -0.46; I2 = 97%) and fatigue (MD, -0.47; 95% CI, -0.59 to -0.34; I2 = 0%) levels had significantly decreased; moreover, up to 3 months after baseline, their stress levels had significantly decreased (MD, -0.79; 95% CI, -1.34 to -0.24; I2 = 0%). CONCLUSION: Mindfulness-based stress reduction interventions are highly beneficial for reducing depression, fatigue, and stress in the short term. IMPLICATIONS FOR PRACTICE: Mindfulness-based stress reduction interventions are cost-effective and practical. Breast cancer survivors are recommended to practice MBSR as part of their daily care routine.

Changes in sexual life experienced by women in Taiwan after receiving treatment for breast cancer.

As the number of breast cancer survivors increases, these patients with sexual problems also increase. For breast cancer survivors, sexual problems are a common and painful experience. Although breast cancer survivors often encounter sexual problems, Taiwanese women are culturally conservative and patients rarely discuss sex problems with clinicians. In this study, we used qualitative methods to better understand the changes in sexual life and related care strategies for breast cancer survivors. Twenty interviews were conducted on clinical patients enrolled in hospitals that received breast cancer treatment. The data were analysed by performing a constant comparative analysis. Three themes emerged: the causes of changes in sexual life, internal response strategies and external response strategies. Ten subthemes were identified. Changes in sexual life in patients with breast cancer in this study included changes related to body image, influence of friends and family, age, genital problems, and illegal love of a partner. Breast cancer survivors can tolerate and regulate sexual life changes by adopting internal and external response strategies. Medical staff must be sensitive and must understand strategies for dealing with sexual life changes that may occur during cancer adjustment and how these strategies can help women's well-being in the rest of their lives.

Naringenin inhibits migration of lung cancer cells via the inhibition of matrix metalloproteinases-2 and -9.

Lung cancer is among the most common causes of cancer-related mortality. It has a high mortality rate and resistance to chemotherapy due to its high metastatic potential. Naringenin, a bioactive compound identified in several fruits, displays anti-inflammatory and antitumor effects. Furthermore, naringenin mitigates the migration of several human cancer cell types. However, the effects of naringenin on lung cancer remain unclear. The current study investigated the mechanisms of naringenin on the migration of lung cancer A549 cells. The results indicate that significant alteration in A549 cell proliferation was observed in response to naringenin (0-300 µM) treatment for 24 and 48 h. Furthermore, a dose-dependent migration inhibition of A549 in the presence of naringenin was observed by healing and transwell migration assays. In addition, a zymography assay revealed that naringenin exhibited a concentration-dependent inhibition of matrix metalloproteinase (MMP)-2 and -9 activities. Furthermore, naringenin also inhibited the activities of AKT in a dose-dependent manner. These observations indicated that naringenin inhibited the migration of lung cancer A549 cells through several mechanisms, including the inhibition of AKT activities and reduction of MMP-2 and -9 activities.

Artery of percheron occlusion in an elderly male: a case report.

Acute bilateral paramedian thalamic and mesencephalic infarcts are uncommon. Occlusion of the artery of Percheron (AOP) is presumed to cause this specific stroke syndrome. However, occlusion of the AOP is rare and early diagnosis is challenging. Here we described a 70-year-old male patient who presented with acute disturbance of consciousness due to acute bilateral paramedian thalamo-mesencephalic infarction secondary to AOP occlusion. Anticoagulant therapy was administered, and his consciousness gradually improved.
