Examining the interrelationships between mindfulness-based interventions, depression, inflammation, and cancer survival.

Depression is highly prevalent in those diagnosed with cancer and is also associated with poorer prognostic outcomes. Mindfulness-based interventions are effective in reducing depressive symptoms and improving quality of life in patients with cancer. The objective of this review was to investigate whether mindfulness practices can improve survival and, if so, what mechanisms of action may contribute to these outcomes. Although no long-term studies have investigated this hypothesis, the current literature supports an inflammatory basis for depression, implicating proinflammatory cytokines and hypothalamic-pituitary-adrenal axis dysfunction as contributing factors. Markers of inflammation, such as interleukin-6, tumor necrosis factor-α, and cortisol, are all found at elevated concentrations in many depressed individuals. These exact mechanisms are associated with higher mortality in patients with cancer. Mindfulness has been studied for its effects on cytokine and cortisol levels, and there are promising data to support that the intervention can measurably decrease inflammation. Therefore, it is conceivable that mindfulness programs can affect survival in this population. There are limited data on the long-term effects of mindfulness on depression and inflammatory markers in patients with cancer, and there are potential barriers to the implementation of mindfulness-based interventions as part of a comprehensive treatment plan. Therefore, it is necessary to further explore these questions through longitudinal studies to establish a survival correlation. CA Cancer J Clin. 2022;72:490-502.

Male-specific late effects in adult hematopoietic cell transplantation recipients: a systematic review from the Late Effects and Quality of Life Working Committee of the Center for International Blood and Marrow Transplant Research and Transplant Complications Working Party of the European Society of Blood and Marrow Transplantation.

Male-specific late effects after hematopoietic cell transplantation (HCT) include genital chronic graft-versus-host disease (GvHD), hypogonadism, sexual dysfunction, infertility, and subsequent malignancies. They may be closely intertwined and cause prolonged morbidity and decreased quality of life after HCT. We provide a systematic review of male-specific late effects in a collaboration between transplant physicians, endocrinologists, urologists, dermatologists, and sexual health professionals through the Late Effects and Quality of Life Working Committee of the Center for International Blood and Marrow Transplant Research, and the Transplant Complications Working Party of the European Society of Blood and Marrow Transplantation. The systematic review summarizes incidence, risk factors, screening, prevention and treatment of these complications and provides consensus evidence-based recommendations for clinical practice and future research.

Male-Specific Late Effects in Adult Hematopoietic Cell Transplantation Recipients: A Systematic Review from the Late Effects and Quality of Life Working Committee of the Center for International Blood and Marrow Transplant Research and Transplant Complications Working Party of the European Society of Blood and Marrow Transplantation.

Male-specific late effects after hematopoietic cell transplantation (HCT) include genital chronic graft-versus-host disease (GVHD), hypogonadism, sexual dysfunction, infertility, and subsequent malignancies, such as prostate, penile, and testicular cancer. These effects may be closely intertwined and cause prolonged morbidity and decreased quality of life after HCT. Here we provide a systematic review of male-specific late effects in a collaboration among transplantation physicians, endocrinologists, urologists, dermatologists, and sexual health professionals through the Late Effects and Quality of Life Working Committee of the Center for International Blood and Marrow Transplant Research and the Transplant Complications Working Party of the European Society of Blood and Marrow Transplantation. We used a systematic review methodology to summarize incidence, risk factors, screening, prevention, and treatment of these complications and provide consensus evidence-based recommendations for clinical practice and future research. Most of the evidence regarding male GVHD is still based on limited data, precluding strong therapeutic recommendations. Therefore, we recommend systematic screening for male genital GVHD regularly and reporting of cases to large registries to allow for a better understanding. Future research also should address treatment, given the little published evidence currently available. Male-specific endocrine consequences of HCT include hypogonadism, which also may affect bone health. Given the scanty evidence, current recommendations for hormone substitution and/or bone health treatment are based on similar principles as for the general population. Following HCT, sexual health decreases, and this topic should be addressed at regular intervals. Future studies should focus on interventional strategies to address sexual dysfunction. Infertility remains prevalent in patients having undergone myeloablative conditioning, warranting the offer of sperm preservation for all HCT candidates. Most studies on fertility rely on descriptive registry analysis and surveys, underscoring the importance of reporting post-HCT conception data to large registries. Although the quality of evidence is low, the development of cancer in male genital organs does not seem more prevalent in HCT recipients compared with the general population; however, subsequent malignancies in general seem to be more prevalent in males than in females, and special attention should be given to skin and oral mucosa. Male-specific late effects, which likely are more underreported than female-specific complications, should be systematically considered during the regular follow-up visits of male survivors who have undergone HCT. Care of patients with male-specific late effects warrants close collaboration between transplantation physicians and specialists from other involved disciplines. Future research should be directed toward better data collection on male-specific late effects and on studies about the interrelationships among these late effects, to allow the development of evidence-based effective management practices.

A Multidisciplinary Team-Based Approach to Improve Communication With Surrogates of Patients With Chronic Critical Illness.

BACKGROUND: Clinicians need to deliver prognostic information to surrogates of nondecisional, critically ill patients so that surrogates can make informed medical decisions that reflect the patient's values. Our objective was to implement a new approach for communicating with surrogates of patients with chronic critical illness. METHODS: Surrogate decision makers of patients who were difficult to liberate from mechanical ventilation were prospectively enrolled. Surrogates met with different members of the intensive care unit treatment team for sequential 15-minute appointments to receive patient-specific assessments and education on chronic critical illness. The feasibility and acceptability of this approach were determined. A 24-question comprehension instrument was developed to assess a participant's understanding that a family member was displaying features of chronic critical illness. Each question was scored from 1 to 5, with larger scores indicating greater comprehension. RESULTS: Over a 15-week period, educational sessions for 9 mechanically ventilated patients were conducted. On average, 2 surrogates per patient (range: 1-4) and 6 members of the interdisciplinary team (range: 4-6) were at each meeting. Surrogates and clinicians had very positive impressions of the communication intervention. The average preintervention comprehension score was 85 of 120 (standard deviation [SD]: 8, range: 71-101). The postintervention comprehension score was greater by 5 points on average (SD: 9, range: -11 to +20 points, P = .04). CONCLUSIONS: Surrogates of critically ill patients approved of this novel communication approach and had a greater understanding of the patient's medical condition after the intervention.

Evaluating connectivity in the brooding brittle star Astrotoma agassizii across the drake passage in the Southern Ocean.

Studies examining population structure and genetic diversity of benthic marine invertebrates in the Southern Ocean have emerged in recent years. However, many taxonomic groups remain largely unstudied, echinoderms being one conspicuous example. The brittle star Astrotoma agassizii is distributed widely throughout Antarctica and southern South America. This species is a brooding echinoderm and therefore may have limited dispersal capacity. In order to determine the effect of hypothesized isolating barriers in the Southern Ocean, such as depth, geographic distance, and the polar front, 2 mitochondrial DNA markers were used to compare populations from the South American and Antarctic continental shelves. Astrotoma agassizii was shown to be genetically discontinuous across the polar front. In fact, populations previously assumed to be panmictic instead represent 3 separate lineages that lack morphological distinction. However, within lineages, genetic continuity was displayed across a large geographic range (>500 km). Therefore, despite lacking a pelagic larval stage, A. agassizii can disperse across substantial geographic distance within continental shelf regions. These results indicate that geographic distance alone may not be a barrier to dispersal, but rather the combined effects of distance, depth, and the polar front act to prevent gene flow between A. agassizii populations in the Southern Ocean.
