Current Opinion in Supportive and Palliative Care最新文献

Purpose of review: The aim of this review is to examine bereavement follow-up intervention studies in critical care, with the purpose of integrating results on the timing, content, aims and outcomes of interventions. The impact of a death in critical care is well documented, and bereavement follow-up is recognised as an important topic, but there is limited research with little consensus on the content and structure of interventions.

Recent findings: A total of 18 papers were selected; 11 are intervention studies, with only one randomised control trial. Six papers were from national surveys and are not the focus of this review. Bereavement follow-up mainly consisted of information giving, condolence interventions, telephone calls and meetings with families. The timing, content, aims and outcomes depended on the intervention and were influenced by the design of the study.

Summary: Overall, bereavement follow-up is acceptable for relatives but outcomes are mixed. Calls for more research are valid, but how do we utilise the current research to better inform the critical care community? Researchers suggest that bereavement follow-up interventions need to be designed with specific aims and outcomes, in collaboration with bereaved families that are appropriate to the intervention.

Purpose of review: This review explores the potential of using novel imaging approaches to deepen our understanding of descending modulatory mechanisms in pain, focussing on functional magnetic resonance imaging (fMRI) of the spinal cord and novel approaches to combining molecular and fMRI data. This review sheds light on the neural processes involved in pain modulation, paving the way for the development of targeted treatments.

Recent findings: The reviewed literature demonstrates significant advancements in pain research. Recent studies show the potential of using fMRI to investigate the spinal cord's role in pain modulation. Furthermore, novel analytical approaches integrating molecular and fMRI data show promise in elucidating the complex neurobiological processes underlying pain regulation. The main themes explored here include the identification of neurochemical markers associated with pain modulation and the characterisation of neural circuits involved in descending pain control.

Summary: A comprehensive understanding of descending modulatory mechanisms in pain can inform the development of novel treatments, targeting dysfunction of these key pathways. By leveraging spinal fMRI and integrating molecular data into brain fMRI, researchers can identify potential therapeutic targets throughout the neuraxis. These advances may contribute to the development of personalised medicine approaches, allowing for tailored interventions based on individual pain profiles.

Purpose of review: The purpose of this review is to provide clear guidance to health professionals delivering chimeric antigen receptor T-cell (CAR-T) therapy on the best supportive management throughout the CAR-T pathway, from referral to long-term follow-up, including psychosocial aspects.

Recent findings: CAR-T therapy has changed the treatment landscape for relapsed/refractory (r/r) B-cell malignancy. Approximately 40% of r/r B-cell leukaemia/lymphoma patients receiving CD19-targeted CAR-T therapy achieve durable remission following a single dose. The field is rapidly expanding to encompass new CAR-T products for indications such as multiple myeloma, mantle cell lymphoma and follicular lymphoma, and the number of patients eligible to receive CAR-T therapy is likely to continue to grow exponentially. CAR-T therapy is logistically challenging to deliver, with involvement of many stakeholders. In many cases, CAR-T therapy requires an extended inpatient hospital admission, particularly in older, comorbid patients, and is associated with potentially severe immune side effects. Further, CAR-T therapy can lead to protracted cytopenias that can last for several months accompanied by a susceptibility to infection.

Summary: For the reasons listed above, standardised, comprehensive supportive care is critically important to ensure that CAR-T therapy is delivered as safely as possible and that patients are fully informed of the risks and benefits, as well as the requirement for extended hospital admission and follow-up, to fully realise the potential of this transformative treatment modality.

Purpose of review: Haematological conditions are varied, and every condition presents unique psychosocial challenges to patients and their families. There is a growing body of evidence about high levels of psychological distress, negative impact on outcomes and evidence-based treatments, yet service provision is patchy and demand far exceeds supply.

Recent findings: This article focuses on the major subspecialty areas and associated neuropsychiatric comorbidities - haematological malignancies, issues related to stem cell transplants, haemoglobinopathies and haemophilia. The subsequent sections focus on common psychiatric comorbidities, considerations across the life span and models of care.

Summary: Anxiety disorders and depression have higher prevalence in people with haematological conditions. The stressors faced by the individual can vary based on their condition and their stage of life. Early diagnosis and integrated management of comorbid psychiatric illness can improve quality of life and clinical outcomes. A stepped care model is recommended to ensure that psychological distress is identified and managed appropriately, and evidence for a collaborative care model is provided.

Purpose of review: Over the past year, loss of appetite in patients with cancer has continued to be an area of active investigation. This review provides an update of recently published findings.

Recent findings: Despite the emergence of new cancer therapeutic agents, this symptom of loss of appetite continues to trouble patients, and it continues to be associated with poor survival. Recent preclinical research promises to lead to newer approaches and newer, more effective palliative agents. Recent clinical research shows that agents such as olanzapine, anamorelin, and cannabis either do or might palliate this symptom.

Summary: Loss of appetite in patients with cancer remains an important area of clinical and research focus. Recent published data provide greater clarity with respect to how to palliate this symptom. Today, although clinicians have more options to palliate cancer-associated loss of appetite than ever before, questions remain unanswered about how to palliate this symptom optimally and how to improve the quality of life of patients who suffer from it.

Purpose of review: Cervical spine radiculopathy (CSR) presents a complex socioeconomic problem for patients, clinicians, families, employers and healthcare systems. Due to the heterogeneity of clinical presentation and underlying mechanisms, clinical assessment can be challenging. This review will examine the literature on the underlying pathophysiology and studies investigating the holistic assessment strategies for this disabling condition. The authors will focus particular attention on the psychological factors associated with CSR and the physical and imaging strategies to establish a diagnosis.

Recent findings: Contemporary CSR assessment should identify the underlying pathomechanisms and how this may impact the somatosensory nervous system integrity and function. No physical assessment test in isolation will establish CSR diagnosis; therefore, clinicians should utilise a cluster of tests and recognise the potential limitations as part of a clinical reasoning framework. The assessment of the somatosensory nervous system can provide insights into particular subgroups of CSR presentation, which may provide interesting opportunities to continue to enhance individualised assessment and management strategies for CSR. The interplay between psychological factors can influence the diagnosis and recovery times for a person with CSR, and clinicians should continue to explore how these factors may influence a person's prognosis. The authors will discuss the opportunities for future research and limitations of contemporary approaches to assessment, underpinned by evidence, and how this supports a clinical assessment to establish CSR diagnosis.

Summary: Research should continue to investigate how clinicians assess the interplay between physical and psychological factors to inform the establishment of CSR. Specifically, there is a need to investigate the validity and reliability of combining somatosensory, motor and imaging assessment findings to reach a diagnosis and inform onward management plans.

Purpose of review: Anamorelin was approved for production and marketing in Japan on 22 January 2021 for cancer cachexia in non-small-cell lung cancer, gastric cancer, pancreatic cancer, and colorectal cancer. The authors describe the updates of anamorelin for cancer cachexia in Japan.

Recent findings: Recent evidence showed that anamorelin improved lean body mass, body weight, and appetite in patients with cancer cachexia in clinical practice. Anamorelin does not increase body weight in the severe-weight-loss group in cachectic patients with pancreatic cancer. Several case reports showed that anamorelin can cause cardiac adverse drug reactions. Among the cardiac adverse reactions, fatal arrhythmias should be monitored carefully even if it is the first dose. Anamorelin combined with nutrition, physical activity, and exercise may be more useful than anamorelin alone for treating cancer cachexia. An interim analysis from post-marketing all-case surveillance was performed; however, details have not yet been published. When anamorelin cannot be used for cancer cachexia, Kampo medicines can be considered as an option.

Summary: Anamorelin has changed the clinical practice of cancer cachexia in Japan. The authors hope that anamorelin is available for other disease-related cachexia along with appropriate multidisciplinary interventions.

Purpose of review: This contemporary and novel review of palliative sedation explores some of the distinctive ethical problems associated with that intervention. It is timely in light of recent reviews of palliative care guidelines on the topic and given the current public debates around the related but distinct practice of euthanasia.

Recent findings: The main themes discussed are patient autonomy, the nature of suffering and how to alleviate it, and the relationship between palliative sedation and euthanasia.

Summary: First, palliative sedation poses a significant problem for patient autonomy, both in terms of securing informed consent and in terms of the ongoing effect on individual well-being. Second, as an intervention to alleviate suffering, it is appropriate only in limited cases and counterproductive in others, for example, where an individual values their ongoing psychological or social agency more than the relief of pain or negative experience. Third, people's ethical views about palliative sedation are often coloured by their understanding of the legal and moral status of assisted dying and euthanasia; this is unhelpful and occludes the interesting and urgent ethical questions raised by palliative sedation as a distinct end-of-life intervention.

Purpose of review: The complexity of the cancer cachexia phenotype has undoubtedly hindered researchers' understanding of this devastating syndrome. The presence and magnitude of host-tumour interactions are rarely considered during clinical decision-making within the current staging paradigm. Furthermore, treatment options for those patients who are identified as suffering from cancer cachexia remain extremely limited.

Recent findings: Previous attempts to characterise cachexia have largely focussed on individual surrogate disease markers, often studied across a limited timeframe. While the adverse prognostic value of clinical and biochemical features is evident, the relationships between these are less clear. Investigation of patients with earlier-stage disease could allow researchers to identify markers of cachexia that precede the refractory stage of the wasting process. Appreciation of the cachectic phenotype within 'curative' populations may aid our understanding of the syndrome's genesis and provide potential routes for prevention, rather than treatment.

Summary: Holistic, longitudinal characterisation of cancer cachexia, across all at-risk and affected populations, is of vital importance for future research in the field. This paper presents the protocol for an observational study aiming to create a robust and holistic characterisation of surgical patients with, or at risk of, cancer cachexia.

Purpose of review: This review aims to synthesise the evidence from systematic reviews and meta-analyses on the efficacy of dignity therapy (DT) in relation to psychosocial and spiritual outcomes in the context of person-centred and culturally competent care for people with supportive and palliative care needs.

Recent findings: Thirteen reviews were found, including seven conducted by nurses. Most reviews were of high quality, including various study populations such as cancer, motor neurone disease and non-malignant conditions. Six psychosocial and spiritual outcomes were identified: quality of life, anxiety, depression, hopefulness, meaning and purpose in life, and suffering based on the cultural variations in the implementation of DT.

Summary: DT has a positive impact on anxiety, depression, suffering, and meaning and purpose in life for people with palliative care needs, but the evidence is somewhat conflicted as to whether DT is effective in improving hope, quality of life and spiritual outcomes in the context of culturally competent care. Nurse-led DT seems desirable given its pivotal role when caring for people with palliative care needs. More randomised controlled trials should be conducted for people with different cultural backgrounds to provide person-centred, culturally competent supportive and palliative care.
