Effectiveness of eHealth mindfulness-based interventions on cancer-related symptoms among cancer patients and survivors: A systematic review and meta-analysis.

OBJECTIVES: This review aimed to synthesize the best available evidence concerning the effectiveness of electronic health, mindfulness-based interventions (eHealth-MBIs) on anxiety, depression, mindfulness and quality of life (QoL) among cancer patients/survivors. METHODS: Published and unpublished studies were retrieved from 10 electronic databases. Two independent authors screened and selected articles, extracted data using a standardized form and appraised the studies with the Cochrane risk of bias assessment tool. Meta-analyses were performed using a random-effect model with Review Manager (REVMAN). Standardized mean differences (SMDs) were used to determine intervention effects. Narrative syntheses were conducted for studies not suitable for meta-analyses. Heterogeneity was identified through I2 and chi-square statistics. Subgroup analyses were performed based on types of controls, age groups and gender. The Grading of Recommendations Assessment, Development and Evaluation approach was used to assess overall quality. RESULTS: In total, 18 studies were included. The eHealth-MBIs improved primary outcomes of anxiety (SMD = -0.28) and depression (SMD = -0.24), among cancer patients/survivors with small effect sizes. Effects for the secondary outcomes of QoL (SMD = 0.25) and mindfulness (SMD = 0.29) were observed at short-term follow-up assessments but not at post-intervention. Overall quality was rated as low for the primary and very low for the secondary outcomes. CONCLUSION: The eHealth-MBIs can be offered as a cost-effective and accessible alternative for cancer patients and survivors in healthcare settings. Future research may further explore the effectiveness of eHealth-MBIs based on different types of MBIs, cancer types, modes of delivery and other outcomes such as stress and post-traumatic growth.

Cocaine- and morphine-induced synaptic plasticity in the nucleus accumbens.

The critical brain areas and molecular mechanisms involved in drug abuse and dependence have been extensively studied. Drug-induced persistent behaviors such as sensitization, tolerance, or relapse, however, far outlast any previously reported mechanisms. A challenge in the field of addiction, therefore, has been to identify drug-induced changes in brain circuitry that may subserve long-lasting changes in behavior. This study examined behavioral changes and electron microscopic evidence of altered synaptic connectivity within the nucleus accumbens (NAc) following repeated administration of cocaine or morphine. The unbiased quantitative stereological physical disector method was used to estimate the number of synapses per neuron. Increases in the synapse-to-neuron ratio were found in the NAc shell of cocaine-treated (49.1%) and morphine-treated (55.1%) rats and in the NAc core of cocaine-treated animals (49.1%). This study provides direct ultrastructural evidence of drug-induced synaptic plasticity and identifies synaptic remodeling as a potential neural substrate underlying drug-induced behavioral sensitization.

An examination of the psychosocial factors influencing colorectal cancer patients' communication of colorectal cancer patient risk with their siblings.

This study examined psychosocial factors influencing colorectal cancer (CRC) patients' communication with their first-degree relatives regarding their CRC risk. Among a sample of CRC patients who were members of a colon registry in New York (n = 127), 60% reported discussing CRC risk with their siblings. These discussions were related to the CRC patients' age of diagnosis, such that those diagnosed before age 45 years were more likely to communicate with their siblings about CRC risk. Despite advances made in CRC prevention, compliance with screening recommendations among individuals who may be at familial risk for the disease is low. Perhaps this underrepresentation reflects how CRC patients communicate with their first-degree relatives about their potential risk for the disease. This study examined the psychosocial factors influencing whether CRC patients communicate with their siblings about CRC risk. The sample included CRC patients with siblings who enrolled in a colon disease registry at a NYC metropolitan hospital. Participants completed questionnaires regarding their current psychosocial functioning, perceived risk of sibling's development of CRC, and communication of CRC risk with their siblings. Patients were predominantly Caucasian, with a mean age of 60.4 years. Of the 127 patients, 60% engaged in discussions with their siblings regarding their CRC risk. Patients diagnosed with CRC before the age of 45 years were more likely to discuss the risk of CRC with their siblings (P < 0.01). These data suggest that CRC patients may serve as an effective vehicle to promote CRC screening and support the need for health care providers to not only educate patients of the familial risk of CRC, but to also encourage these patients to communicate this information with their siblings.

Demographic, medical, and psychosocial correlates to CAM use among survivors of colorectal cancer.

GOALS OF WORK: Complementary and alternative medicines (CAM) use among cancer patients is becoming more prevalent; however, our understanding of factors contributing to patients' decisions to participate in CAM is limited. This study examined correlates of CAM use among colorectal cancer (CRC) survivors, an understudied population that experiences many physical and psychological difficulties. MATERIALS AND METHODS: The sample was 191, predominantly white, CRC survivors (mean age = 59.9 +/- 12.6) who were members of a colon disease registry at a NYC metropolitan hospital. Participants completed assessments of sociodemographic characteristics, psychosocial factors [e.g., psychological functioning, cancer specific distress, social support (SS), quality of life (QOL)], and past CAM use (e.g., chiropractic care, acupuncture, relaxation, hypnosis, and homeopathy). MAIN RESULTS: Seventy-five percent of participants reported using at least one type of CAM; most frequently reported was home remedies (37%). Younger (p < 0.01) or female patients (p < 0.01) were more likely to participate in CAM than their older male counterparts. Among psychosocial factors, poorer perceived SS (p = 0.00), more intrusive thoughts (p < 0.05), and poorer overall perceived QOL (p < 0.05) were associated to CAM use. In a linear regression model (including age, gender, SS, intrusive thoughts, and perceived QOL), only age remained a significant predictor of CAM use. CONCLUSION: These findings demonstrate that CAM use is prevalent among CRC survivors and should be assessed routinely by providers. CAMs may serve as a relevant adjunct to treatment among CRC patients as well as an indication of need for additional SS, especially among younger patients.
