Myokines may target accelerated cognitive aging in people with spinal cord injury: A systematic and topical review.

Persons with spinal cord injury (SCI) can suffer accelerated cognitive aging, even when correcting for mood and concomitant traumatic brain injury. Studies in healthy older adults have shown that myokines (i.e. factors released from muscle tissue during exercise) may improve brain health and cognitive function. Myokines may target chronic neuroinflammation, which is considered part of the mechanism of cognitive decline both in healthy older adults and SCI. An empty systematic review, registered in PROSPERO (CRD42022335873), was conducted as proof of the lack of current research on this topic in people with SCI. Pubmed, Embase, Cochrane and Web of Science were searched, resulting in 387 articles. None were considered eligible for full text screening. Hence, the effect of myokines on cognitive function following SCI warrants further investigation. An in-depth narrative review on the mechanism of SCI-related cognitive aging and the myokine-cognition link was added to substantiate our hypothetical framework. Readers are fully updated on the potential role of exercise as a treatment strategy against cognitive aging in persons with SCI.

Altered Circulating Immune Cell Distribution in Traumatic Spinal Cord Injury Patients in Relation to Clinical Parameters.

Following a spinal cord injury (SCI), an inflammatory immune reaction is triggered which results in advanced secondary tissue damage. The systemic post-SCI immune response is poorly understood. This study aimed to extensively analyse the circulating immune cell composition in traumatic SCI patients in relation to clinical parameters. High-dimensional flow cytometry was performed on peripheral blood mononuclear cells of 18 traumatic SCI patients and 18 healthy controls to determine immune cell subsets. SCI blood samples were collected at multiple time points in the (sub)acute (0 days to 3 weeks post-SCI, (s)aSCI) and chronic (6 to >18 weeks post-SCI, cSCI) disease phase. Total and CD4+ T cell frequencies were increased in cSCI patients. Both CD4+ T cells and B cells were shifted towards memory phenotypes in (s)aSCI patients and cSCI patients, respectively. Most profound changes were observed in the B cell compartment. Decreased immunoglobulin (Ig)G+ and increased IgM+ B cell frequencies reflected disease severity, as these correlated with American Spinal Injury Association (ASIA) impairment scale (AIS) scores. Post-SCI B cell responses consisted of an increased frequency of CD74+ cells and CD74 expression level within total B cells and B cell subsets. Findings from this study suggest that post-SCI inflammation is driven by memory immune cell subsets. The increased CD74 expression on post-SCI B cells could suggest the involvement of CD74-related pathways in neuroinflammation following SCI. In addition, the clinical and prognostic value of monitoring circulating IgM+ and IgG+ B cell levels in SCI patients should be further evaluated.

Exposure in Vivo as a Treatment Approach to Target Pain-Related Fear: Theory and New Insights From Research and Clinical Practice.

Pain-related fear (PRF) can be a significant factor contributing to the development and maintenance of pain-related disability in individuals with persistent pain. One treatment approach to target PRF and related avoidance behavior is exposure in vivo (EXP). EXP has a long history in the field of anxiety, a field that is constantly evolving. This Perspective outlines recent theoretical advancements and how they apply to EXP for PRF, including suggestions for how to optimize inhibitory learning during EXP; reviews mechanistic work from neuroimaging supporting the targeting of PRF in people with chronic pain; and focuses on clinical applications of EXP for PRF, as EXP is moving into new directions regarding who is receiving EXP (eg, EXP in chronic secondary pain) and how treatment is provided (EXP in primary care with a crucial role for physical therapists). Considerations are provided regarding challenges, remaining questions, and promising future perspectives. IMPACT: For patients with chronic pain who have elevated pain-related fear (PRF), exposure is the treatment of choice. This Perspective highlights the inhibitory learning approach, summarizes mechanistic work from experimental psychology and neuroimaging regarding PRF in chronic pain, and describes possible clinical applications of EXP in chronic secondary pain as well as in primary care.

Learning self-care skills after spinal cord injury: a qualitative study.

BACKGROUND: People with a recent spinal cord injury (SCI) often follow intensive rehabilitation. Learning appropriate self-care, deal with their impairments and prevent secondary health conditions (SHCs), is highly important during rehabilitation. To date it is not clear how self-care skills are taught to people with SCI. The objective of this study was to understand how people with SCI experienced the learning of appropriate self-care skills during inpatient rehabilitation, including the role of the rehabilitation team. METHODS: Individual semi-structured interviews were conducted with 15 people with SCI, recently discharged from initial inpatient rehabilitation. Interviews were audio-taped, transcribed and analyzed thematically. RESULTS: Two main themes and seven sub-themes were identified. Participants stated that the contribution of the rehabilitation team to learning self-care, including prevention of SHCs, was mostly made by optimizing opportunities to learn through experience. For preventing SHCs, education and lessons learned from the professionals during therapy and the formal educational program, was experienced as especially important. Further, the motivational attitude of the professionals which participants found stimulating and was based on respect, combined with their positive contribution as one team, were seen as essentials elements for learning appropriate self-care. However participants did not recognize the contribution of the nursing staff as part of their rehabilitation, although it was seen as very important. An important aspect of the participants' own contribution was challenging oneself to learn self-care. This was done in different ways by the participants. Further, their own mental adjustment was considered important in the learning process. The gaining of confidence was by most participants seen as personal characteristic, although they also recognized the importance of the team effort and the experiences they underwent. CONCLUSIONS: Learning appropriate self-care was mostly done through experience, by challenging themselves, and making use of the opportunities given by the members of the rehabilitation team. The same strategies used by the rehabilitation team to teach people with SCI to perform appropriate self-care, were also helpful for the participants to gain confidence. Explicit attention for self-care training as an important goal in SCI rehabilitation may strengthen the nursing staff's role and stimulate interdisciplinary working.

Effectiveness of Exposure in Vivo for Patients with Painful Diabetic Neuropathy: a Pilot Study of Effects on Physical Activity and Quality of Life.

OBJECTIVE: To evaluate the effects of personalized exposure in vivo on level of physical activity and quality of life in patients with painful diabetic neuropathy. DESIGN: Randomized, single-case, ABC design. SUBJECTS: Twelve patients with painful diabetic neuropathy, age > 18 years, diabetes mellitus type II, Clinical Neurological Examination score > 5, Diabetic Neuropathy Symptom Score ≥ 1 and Douleur Neuropathique 4 Questions score ≥ 3. METHODS: The treatment consists of an Intensive screening, followed by an 8-week exposure in vivo intervention specifically adapted to the needs/risks of patients with painful diabetic neuropathy, and 6-months follow-up. Outcome measures included daily and non-daily measures of physical activity, quality of life, metabolic parameters, disability, depression, general and painful diabetic neuropathy-related anxiety, pain intensity and pain catastrophizing. RESULTS: Due to high drop-out rates (n = 6 during screening, n = 2 during treatment, n = 1 after treatment), only 3 participants completed the study. Slight, but non-significant, changes in physical activity and disability were observed. In quality of life, no changes were observed. CONCLUSION: Analysis of the reasons for the high drop-out rate indicate that exposure in vivo may have added value in patients with painful diabetic neuropathy only for those patients: (i) whose daily life functioning is impaired mainly by the painful diabetic neuropathy; (ii) in whom painful diabetic neuropathy-related fears are exaggerated and irrational; (iii) in whom specific activities evoke the painful diabetic neuropathy-related fears; (iv) whose spouse and healthcare providers are involved in the treatment; and (v) who are willing to change their daily behaviour. Further research is needed into this subject.

The effect of exercise therapy combined with psychological therapy on physical activity and quality of life in patients with painful diabetic neuropathy: a systematic review.

Background and aims Approximately 25% of patients with diabetes mellitus type 2 (DMII) develop painful diabetic neuropathy (PDN). PDN is known to affect both mental and physical wellbeing, resulting in anxiety, depression, low quality of life and physical disability. Pharmacological treatment of PDN aims at pain relief and is often ineffective and/or has many side effects. Rehabilitation treatment modalities that are designed to help the patient deal with PDN related complaints, are mostly focussed on either physical (e.g. exercise therapy) or psychological aspects (e.g. cognitive behavioural therapy, CBT). There is emerging evidence that PDN can be approached from a biopsychosocial perspective, in which physical and psychosocial aspects are integrated. From this biopsychosocial approach it is plausible that integrated treatment modalities such as acceptance commitment therapy (ACT) or exposure in vivo (EXP) could be effective in patients with PDN. The objective of this review was to provide an overview of the current evidence on the effects of rehabilitation treatments that combine exercise therapies with psychological therapies in order to improve physical activity (PA) and quality of life (QoL) in patients with PDN. Methods Systematic review of the current literature. EMBASE, MEDLINE, Medline In-Process citations and e-Pubs ahead-of-print, Pedro, Web of Science, PsycINFO, CENTRAL, PubMed and Google Scholar were searched. All studies on interventions combining exercise therapy with psychological interventions in patients with PDN, aged >18 years, were included. Outcome measures were PA, QoL. Results The search resulted in 1603 records after removing duplicates. After screening on titles and abstracts, 100 records remained. From these, not one study reported on interventions that combined exercise therapy with psychological interventions. Through a secondary hand search, a total of three reviews were identified that described a total of five studies regarding either physical or psychological interventions in patients with PDN. These studies reported moderate effects of (1) mindfulness meditation on QoL, (2) CBT on pain severity, (3) mindfulness-based stress reduction intervention on function, health-related QoL, pain catastrophizing and depression, (4) aerobic exercise on QoL and (5) Tai Chi on glucose control, balance, neuropathic symptoms, and some dimensions of QoL in patients with PDN. All studies were of a moderate quality, and results should be interpreted with caution. Conclusions Based on increasing knowledge in the domain of chronic pain, it could be assumed that integrated rehabilitation treatments for patients with PDN are beneficial. There is no literature to support this and more research should be done on integrated biopsychosocial interventions in patients with PDN. Implications This empty review highlights the importance that more research should be done on integrated biopsychosocial interventions in patients with PDN. Currently, our research group is performing a study on the effects of EXP treatment in patients with PDN.

Living with painful diabetic neuropathy: insights from focus groups into fears and coping strategies.

OBJECTIVE: Painful diabetic neuropathy (PDN) is known to negatively affect quality of life. Being physically active is a crucial part of successful diabetes self-management, but regimen adherence is often low. Coping strategies and fears have shown to be related to less physical activity (PA). The aim of the present study was to obtain more in-depth information on psychological risk factors leading to less PA in persons with PDN. DESIGN: Three semi-structured focus group interviews were conducted with a representative sample of persons with PDN (N = 12). Data were transcribed verbatim and analysed using a hybrid method of thematic analyses and a grounded theory approach. MAIN OUTCOME MEASURES: Fears and coping strategies related to PA in persons with PDN. RESULTS: Several specific fears were identified; fear of hypoglycaemia, fear of pain increase, fear of total exhaustion, fear of physical injury, fear of falling, fear of loss of identity, and fear of negative evaluation by others. To cope with these fears, avoidance, remaining active, cognitive distraction, and acceptance strategies were described. CONCLUSION: In persons with PDN, diabetes-related fears and pain-related fears play a role in less engagement in PA, indicating the need for new methods for improving self-management in persons with PDN.

Biopsychosocial Rehabilitation Treatment "Exposure In Vivo" for Patients with Painful Diabetic Neuropathy: Development of a Treatment Protocol.

OBJECTIVE: Painful diabetic neuropathy is associated with low quality of life, depression and anxiety. Patients are limited in their performance of activities of daily living due to fears related to their condition. Treatment modalities are needed to help patients cope with their pain and pain-related disability. Exposure in vivo is an effective treatment in other chronic pain syndromes, increasing patients' functional ability and quality of life. This paper presents an Exposure in vivo treatment protocol for patients with painful diabetic neuropathy. PROTOCOL: An 8-week Exposure in vivo treatment protocol was specifically adapted to the needs and risks of patients with painful diabetic neuropathy. New screening tools were developed for patients with PDN; the Painful Diabetic Neuropathy Anxiety Rasch-Transformed Questionnaire (PART-Q30) identifies specific fears related to painful diabetic neuropathy (e.g. fear of hypoglycaemia); and a customized version of the Photograph-series Of Daily Activities (PHODA-PDN) detects fear-eliciting activities related to the condition in individual patients. During Exposure in vivo, catastrophic interpretations regarding painful stimuli are challenged and corrected, thereby diminishing pain-related fear and enabling the patient to re-engage in activities of daily living. An interdisciplinary team provides Exposure in vivo in 1-h sessions twice a week. DISCUSSION: To the best of our knowledge, this treatment protocol is the first intervention using Exposure in vivo specifically adapted to the needs and risks of patients with painful diabetic neuropathy.
