Non-pharmacological interventions to improve mental health outcomes among female carers of people living with a neurological condition: a systematic review.

PURPOSE: This systematic review aims to examine the effectiveness of non-pharmacological interventions for improving mental health outcomes among female carers of people living with a neurological condition. MATERIALS AND METHODS: A narrative synthesis of English-language randomized controlled trials was undertaken. RESULTS: 18 unique studies were included. Intervention components that were found to have improved mental health outcomes were: delivered in person, to groups, on an intermittent schedule with ≥10 sessions; had a duration between 3-6 months; and were facilitated by research staff or allied health professionals. As the review had few robust studies, results of mental health outcomes reported in studies assessed as low risk of bias were highlighted in the review. Psychoeducation interventions, cognitive behavioural interventions, and support group interventions were found to improve depression. Psychoeducation interventions were also found to improve burden. CONCLUSIONS: There is a clear need for adequately powered, high-quality randomised controlled trials to determine the effectiveness of non-pharmacological interventions for female carers of people living with a neurological condition.

Female carers experience worse mental health and well-being outcomes and are at a higher risk of developing chronic health issues compared to their male counterparts.This review identified only very few, generally small, randomised controlled trials of non-pharmacological interventions in female carers of patients with neurological conditions.Interventions that provide psychoeducation, are group-based, face-to-face, and have an intervention duration between >3 months and <6 months, may be successful in improving some mental health outcomes, such as depression and coping.

Trigeminal and Glossopharyngeal Neuralgia.

Trigeminal neuralgia and glossopharyngeal neuralgia are craniofacial pain syndromes characterized by recurrent brief shock-like pains in the distributions of their respective cranial nerves. In this article, the authors aim to summarize each condition's characteristics, pathophysiology, and current pharmacotherapeutic and surgical interventions available for managing and treating these conditions.

Removal of a flanged ventricular catheter: illustrative case.

BACKGROUND: Flanged ventricular catheters were created in the 1970s to decrease shunt failure by preventing the holes at the catheter tip from contacting the choroid plexus. However, the flanges on the catheter frequently scarred within and tether to the choroid plexus, resulting in higher rates of intraventricular hemorrhage when removed. Today, flanged catheters are rarely encountered. OBSERVATIONS: The authors describe an illustrative case of a 7-year-old girl recently adopted from another country with a history of myelomeningocele and shunted hydrocephalus. She had been treated with a flanged catheter at birth. She presented with a shunt infection, which required removal of the flanged catheter tethered to the choroid. LESSONS: The authors illustrate the safe removal of a posterior-entry flanged ventricular catheter tethered to the choroid plexus using monopolar flexible electrocautery. The removal was monitored with a flexible endoscope inserted from an ipsilateral anterior burr hole and was followed by an endoscopic third ventriculostomy.

Ulnar fascicle to brachialis branch of musculocutaneous nerve for restoration of elbow flexion associated with spinal cord tumor and radiation-induced lower motor neuron disease.

Transfer of the ulnar fascicle to the biceps branch of the musculocutaneous nerve, or Oberlin transfer, has been widely used for the treatment of elbow flexion weakness in the setting of upper trunk brachial plexus palsy. The authors present a modified application of this technique for restoration of functional elbow flexion in a 30-year-old woman with a history of recurrent upper cervical spinal cord pilocytic astrocytoma, complex spinal deformity, and radiation-induced lower motor neuron disease.

Trigeminal Neuralgia: Diagnosis and Treatment.

Trigeminal neuralgia is characterized classically by recurrent, evocable, unilateral brief, electric, shocklike pains with an abrupt onset and cessation that affects one or more divisions of the trigeminal nerve. In recent years, the classification of trigeminal neuralgia has been updated based on further understanding. In this manuscript, the authors aim to explain the current understanding of the pathophysiology of trigeminal neuralgia, current diagnosis criteria, and the pharmacologic management and surgical treatments of options currently available.

Case report: MR-guided laser induced thermal therapy for palliative cingulotomy.

In end-stage cancer, oncologic pain refractory to medical management significantly reduces patients' quality of life. In recent years, ablative surgery has seen a resurgence in treating diffuse and focal cancer pain in terminal patients. The anterior cingulate gyrus has been a key focus as it plays a role in the cognitive and emotional processing of pain. While radiofrequency ablation of the dorsal anterior cingulate is well described for treating cancer pain, MRI-guided laser-induced thermal therapy (LITT) is novel. Our paper describes a patient treated with an MRI-guided LITT therapy of the anterior cingulate gyrus for intractable debilitating pain secondary to terminal metastatic cancer.

Neuroablative central lateral thalamotomy for chronic neuropathic pain.

Chronic neuropathic pain refractory to medical management can be debilitating and can seriously affect one's quality of life. The interest of ablative surgery for the treatment or palliation of chronic neuropathic pain, cancer-related or chemotherapy-induced, has grown. Numerous regions along the nociceptive pathways have been prominent targets including the various nuclei of the thalamus. Traditional targets include the medial pulvinar, central median, and posterior complex thalamic nuclei. However, there has been little research regarding the role of the central lateral nucleus. In this paper, we aim to summarize the anatomy, pathophysiology, and patient experiences of the central lateral thalamotomy.

A qualitative assessment of the pulmonary rehabilitation decision-making needs of patients living with COPD.

Pulmonary rehabilitation (PR) is highly evidenced but underutilised in patients living with chronic obstructive pulmonary disease (COPD). A menu of centre and home-based programmes is available to facilitate uptake but is not routinely offered. An appraisal of the current PR referral approach compared to a menu-based approach was warranted to explore the decision-making needs of patients living with COPD when considering a referral to PR. Face-to-face or telephone, semi-structured interviews were conducted with patients diagnosed with COPD and referred to PR and referring HCPs. Interviews were audio-recorded, transcribed verbatim and analysed using the enhanced critical incident technique. 14 HCPs and 11 patients were interviewed (n = 25). Interview data generated 276 critical incidents which informed 28 categories (30 sub-categories). Five high-level themes captured patients' decision-making needs for PR: Understanding COPD, understanding PR, perceived ability to access PR, a desire to accept PR, and supporting the offer. A menu-based approach would further support patients' PR decision-making, however, insufficient knowledge of the programmes would limit its perceived feasibility and acceptability. The development of shared decision making interventions (e.g., a patient decision aid) to elicit patient-centred, meaningful discussions about the menu is suggested.

Transitions for older people with learning disabilities and behaviours that challenge others, and their family carers: a merged protocol for two rapid scoping reviews of evidence.

BACKGROUND: There are over 1 million adults with a learning disability in the UK, of whom approximately 20% displaying behaviours that challenge others. Two thirds of people with learning disabilities live in the family home. As they and their family carers age, both are likely to face particular difficulties and stresses, but there is little understanding of their experiences and needs. To address this evidence gap, our main objective is to undertake two rapid scoping reviews that will collectively focus on the health and social care needs, experiences, service interventions and resources of older people with learning disabilities and behaviours that challenge others, and their family carers. Both reviews will focus on issues relating to forward planning and transitions to different care contexts. The study is part of a research project funded by the National Institute for Health Research No.129491. METHODS: We propose to address the need for evidence via two rapid scoping reviews. We will include published and unpublished (grey) literature, encompassing empirical research, policy and practice guidance and lay resources to support decision-making. We will search multiple electronic databases, hand search references lists, and use expert guidance to identify potential evidence. The following databases were used for research and grey literature: CINAHL; Healthcare Management Information Consortium (HMIC); NHS Evidence; Scopus; Turning Evidence Into Practice (TRIP); Web of Science (WoS); Google (first 5 pages); and Google Scholar (first 5 pages). For RR2, additional intended databases are the Carer Research Knowledge Exchange Network (CAREN) and Social Care Institute for Excellence (SCIE). Two reviewers will independently screen all citations and full-text articles for inclusion. One reviewer will extract data, with an independent review undertaken by the research team. Critical appraisal will depend on the nature of included evidence. Narrative synthesis will be collaboratively developed, with descriptive information presented in tables summarising study characteristics and thematic analysis of findings presented in the main text. Dissemination will be through journal publication, conference presentations and written short-form, easy-read versions of articles and audio-video clips for lay audiences. DISCUSSION: We will consider the strengths and limitations of our reviews, considering their impact on findings. We will summarise the main findings and provide an interpretation linked to the review questions and objectives. We will consider the implications of our findings for policy and practice, as well as future research addressing the support of older people with learning difficulties and behaviours that challenge others, and their family carers, in the context of transition to different care contexts in the UK. The protocol has been registered as Vseteckova, J., Jordan, J., Tilley, E., Larkin, M., Ryan, S., and Wallace, L. (2021, December 4).

Single-center outcomes for percutaneous pedicle screw fixation in metastatic spinal lesions: can spontaneous facet fusion occur?

OBJECTIVE: Survival of cancer patients continues to improve with systemic treatment advancements, leading to an increase in cancer-related complications such as pathological spinal fractures. In this study, the authors aimed to evaluate the outcome of percutaneous stabilization with cement augmentation of the pedicle screws in the management of patients with metastatic cancer to the spine. METHODS: The authors reviewed a retrospective case series of 74 patients with symptomatic pathological spine fractures treated with cement-augmented pedicle screws implanted with a percutaneous technique. The mean imaging follow-up was 11.3 months. Data on demographics, clinical outcomes, and complications were collected. Cement extravasation, spinal hardware integrity, and fusion rates were assessed on CT scans. RESULTS: Among 50 patients with follow-up imaging, 23 patients (46%) showed facet joint fusion. The length of segmental stabilization was not a significant predictor of the occurrence of fusion. Pre- or postoperative radiation therapy, postoperative chemotherapy, and the location of spinal lesions did not have a statistically significant effect on the occurrence of fusion. Patients older than 60 years of age were more likely to have fusion across facet joints compared with younger patients. There was a significant difference in the mean visual analog scale pain score, with 6.28 preoperatively and 3.41 postoperatively, regardless of fusion status (p < 0.001). Cement extravasation was seen in 51% of the cohort, but in all instances, patients remained asymptomatic. Most importantly, the incidence of hardware failure was low (4%). CONCLUSIONS: Percutaneous fixation with cement-augmented pedicle screws in patients with pathological spine fractures provides an improvement in mechanical back pain, with a low incidence of failure, and in some patients, spontaneous facet fusion was observed. Further research is necessary with regard to both short-term benefits and long-term outcomes.

Digital Medicine in Men with Advanced Prostate Cancer - A Feasibility Study of Electronic Patient-reported Outcomes in Patients on Systemic Treatment.

AIMS: Electronic patient-reported outcome (ePRO) measures have the potential to improve patient care, both at an individual level by detecting symptoms and at an organisational level to rationalise follow-up. The introduction of ePROs has many challenges, including funding, institutional rigidity and acceptability for both patients and clinicians. There are multiple examples of successful ePRO programmes but no specific feasibility studies in those who are less digitally engaged. Prostate cancer is predominantly a disease of older men and digital exclusion is associated with increased age. We assessed the feasibility of ePRO completion in older men receiving treatment for advanced prostate cancer both within the clinic and from home. MATERIALS AND METHODS: Men receiving palliative systemic treatment were asked to complete ePROs on a tablet computer in the outpatient department at 0 and 3 months. Participants were also offered optional completion from home. Feasibility was assessed via a mixed methods approach. RESULTS: On-site ePRO completion was acceptable to most patients, with 90% finding it easy or straightforward and 80% preferring electronic over paper. Remote completion was more challenging, even for those who accessed e-mail daily and owned a tablet, with only 20% of participants successfully completing ePROs. Barriers to electronic completion can be categorised as technical, attitudinal and medical. Quality of life and symptom ePRO results were comparable with published data. CONCLUSIONS: On-site completion is achievable in this population with limited staff support. However, remote completion requires further work to improve systems and acceptability for patients. Remote completion is critical to add significantly to current clinical care by detecting symptoms or stratifying follow-up.

Neurostimulation for treatment-resistant posttraumatic stress disorder: an update on neurocircuitry and therapeutic targets.

Posttraumatic stress disorder (PTSD) is a widespread and often devastating psychiatric condition. Core symptoms include intrusive and distressing thoughts, heightened reactivity, mood changes, cognitive impairments, and consequent avoidance of trauma-related stimuli. Symptoms of PTSD are often refractory to standard treatments, and neuromodulatory techniques have therefore drawn significant interest among the most treatment-resistant patients. Transcranial magnetic stimulation has demonstrated minimal efficacy, and deep brain stimulation trials are currently ongoing. PTSD is a disorder of neural circuitry; the current understanding includes involvement of the amygdala (basolateral and central nuclei), the prefrontal cortex (ventral medial and dorsolateral regions), and the hippocampus. Neuroimaging and optogenetic studies have improved the understanding of large-scale neural networks and the effects of microcircuitry manipulation, respectively. This review discusses the current PTSD literature and ongoing neurostimulation trials, and it highlights the current understanding of neuronal circuit dysfunction in PTSD. The authors emphasize the anatomical correlations of PTSD's hallmark symptoms, offer another potential deep brain stimulation target for PTSD, and note the need for continued research to identify useful biomarkers for the development of closed-loop therapies. Although there is hope that neuromodulation will become a viable treatment modality for PTSD, this concept remains theoretical, and further research should involve institutional review board-approved controlled prospective clinical studies.

Percutaneous Computed Tomography-Guided Radiofrequency Ablation of Spinal Trigeminal Tract and Nucleus Caudalis for Refractory Trigeminal Neuropathic Pain: 2-Dimensional Operative Video.

This is a surgical video of a computed tomography (CT)-guided percutaneous radiofrequency ablation of the spinal trigeminal tract and nucleus caudalis for refractory trigeminal neuropathic pain.1,2 Many have contributed historically, among them, Sjoqvist3 in 1938 first described destruction of the descending medullary trigeminal tractus via open craniotomy.3-6 In 1967 and 1968, Crue7 and Hitchcock8 independently developed a percutaneous tractotomy technique. Although Kanpolat9,10 first described the use of CT imaging for percutaneous creation of a single tractotomy/nucleotomy lesion resulting in satisfactory pain relief for 85% of patients. The spinal trigeminal tract is a descending fiber pathway containing central processes of first-order afferent neurons from cranial nerves V, VII, IX, and X. The spinal trigeminal nucleus is the terminal projection of the spinal trigeminal tract comprised of 3 subnuclei: oralis, interpolaris, and caudalis. The nucleus caudalis is the most caudal of the 3 subdivisions of the spinal trigeminal nucleus and houses the cell bodies of second-order afferent neurons critical in nociception of the face. Lesioning of the spinal trigeminal tract and nucleus caudalis can provide pain relief without affecting facial sensation or trigeminal motor function.9,11-13 Percutaneous radiofrequency ablation is performed using anatomical landmarks, serial CT scans, impedance monitoring, and functional confirmation to ensure appropriate insertion of the probe to the target of interest prior to lesioning. This procedure remains uncommon in current practices even among functional neurosurgery pain specialists but offers a low-risk, minimally invasive treatment option for refractory facial pain.14 This procedure was done under Institutional Review Board guidance (H-41228: retrospective chart review of patients undergoing spine surgery for pain). The risks and benefits were explained, and the patient consented to videography/procedure. Images in the video used with permission from the following: Carter HV. Anatomy of the Human Body.

Medical infrared thermal imaging of syringomyelia in the Cavalier King Charles Spaniel.

BACKGROUND: Medical infrared thermal imaging (MITI) is a non-invasive imaging modality gaining popularity in the veterinary field. An infrared camera captures emission of heat and creates a color map in the form of a thermogram. Topical heat emission is influenced by localized disease processes as a result of autonomic nervous system imbalance. The purpose of this study was to determine the utility of using thermography to identify changes in thermographic patterns associated with syringomyelia (SM) presence or absence in Cavalier King Charles Spaniels (CKCS) with Chiari-like Malformation (CLM). RESULTS: In CKCS with CLM, MITI was most accurate at a texture distance of 6. Optimizing imaging feature sets produced a highest accuracy of 69.9% (95% CI: 59.5-79.0%), with 81.3% sensitivity and 57.8% specificity for identifying the presence of syringomyelia. CONCLUSION: Thermographic image analysis is a successful non-invasive, diagnostic test that can be used to screen for syringomyelia presence in a CKCS with CLM.

A Multimedia Educational Module for Teaching Early Medical Neuroanatomy.

Introduction: As the global burden of neurological disorders continues to rise, physicians' need for a solid understanding of neuroanatomy is becoming more important. Traditional neuroanatomy curricula offer a limited approach to educating a diverse profile of learning styles. In an attempt to incorporate recent literature addressing diverse learning formats, we developed and evaluated two new image-based resources for the neuroscience curriculum. Methods: We created narrated videos demonstrating the brain dissections that students were to perform in the laboratory and quiz-style, postdissection review slides for later self-guided study. These were offered as optional study aids to two classes of preclerkship medical students at the Uniformed Services University of the Health Sciences F. Edward Hébert School of Medicine. Effectiveness was evaluated through examination questions, and a survey was administered to one of the classes to assess usage of and satisfaction with the materials. Results: Mean scores on the practical examination questions were 83% and 89% for the two classes of students given the resources. Notably, 100% of respondents used the review slides after the laboratory, and more than 99% found them very helpful or extremely helpful for learning relevant concepts. Discussion: Our results support the usefulness of these resources as learning tools for neuroanatomy. These resources were meant to augment various traditional resources (textbooks, lecture) to provide a broad range of study options in line with current research. Our experience suggests that similar tools could be developed for application in other visually based content areas of the preclerkship curriculum.

Percutaneous CT-guided cordotomy for pain.

Cordotomy has evolved since the first open procedure by Spiller and the first percutaneous radiofrequency cordotomy by Mullan in 1965. Today, the minimally invasive, CT-guided percutaneous radiofrequency cordotomy is mostly used for the palliative management of medically intractable somatic pain related to malignancy in well-selected patients. The risk of adverse events is minimized with the use of intraoperative stimulation monitoring. This video highlights the spinal cord anatomy at the level of C1-2, the approach to patient selection, the associated risks and benefits, and, finally, the procedural setup and key steps involved in this unique neurosurgical procedure. The video can be found here: https://youtu.be/a-0ORqy0W2o.

Limited midline myelotomy for visceral pain.

The traditional commissural myelotomy consists of a sagittal cut in the midline and was originally described by Greenfield and performed by Armour in 1926. Today, myelotomy refers to the selective disruption of the ascending visceral pain pathway. The success of the procedure is incumbent on the correct identification of the midline. Limited midline open myelotomy for the treatment of medically intractable abdominal or pelvic visceral cancer pain, with the aid of somatosensory evoked potentials to identify midline, offers patients superior pain relief over similar percutaneous techniques. Multicenter registries are needed to better elucidate the best surgical technique for this procedure. The video can be found here: https://youtu.be/0unlmwp08po.

Stereotactic Radiosurgery Hypophysectomy for Palliative Treatment of Refractory Cancer Pain: A Historical Review and Update.

Medically refractory pain in those with advanced cancer significantly reduces one's quality of life. Therefore, palliative interventions to mitigate cancer pain and reduce opioid requirements are necessary to reduce patient suffering and opioid-induced side effects. Hypophysectomy, a largely forgotten pain procedure with several technical variations, has been repeatedly studied in small series with encouraging results, though historically has been fraught with complications. As a result, the minimally invasive and more tolerable stereotactic radiosurgery (SRS) hypophysectomy has resurfaced as a possible treatment for cancer-related pain. While the mechanism of pain relief is not entirely understood, the hypothalamohypophyseal axis appears to play an essential role in pain perception and transmission and involves C fiber signal processing and downstream modulation of the brainstem and spinal cord via the hypothalamus. This review highlights the role of hypophysectomy in alleviating advanced cancer pain, both in hormonal and nonhormonal malignancy and the current mechanistic understanding of pain relief for the three primary hypophysectomy modalities used historically: surgical and chemical adenolysis, as well as the more recent, SRS hypophysectomy. Given the lack of high-quality evidence for stereotactic radiosurgery hypophysectomy, there is a need for further rigorous and prospective clinical studies despite its ideal and noninvasive approach.

Two-year mortality and functional outcomes in combat-related penetrating brain injury: battlefield through rehabilitation.

OBJECTIVEThere are limited data concerning the long-term functional outcomes of patients with penetrating brain injury. Reports from civilian cohorts are small because of the high reported mortality rates (as high as 90%). Data from military populations suggest a better prognosis for penetrating brain injury, but previous reports are hampered by analyses that exclude the point of injury. The purpose of this study was to provide a description of the long-term functional outcomes of those who sustain a combat-related penetrating brain injury (from the initial point of injury to 24 months afterward).METHODSThis study is a retrospective review of cases of penetrating brain injury in patients who presented to the Role 3 Multinational Medical Unit at Kandahar Airfield, Afghanistan, from January 2010 to March 2013. The primary outcome of interest was Glasgow Outcome Scale (GOS) score at 6, 12, and 24 months from date of injury.RESULTSA total of 908 cases required neurosurgical consultation during the study period, and 80 of these cases involved US service members with penetrating brain injury. The mean admission Glasgow Coma Scale (GCS) score was 8.5 (SD 5.56), and the mean admission Injury Severity Score (ISS) was 26.6 (SD 10.2). The GOS score for the cohort trended toward improvement at each time point (3.6 at 6 months, 3.96 at 24 months, p > 0.05). In subgroup analysis, admission GCS score ≤ 5, gunshot wound as the injury mechanism, admission ISS ≥ 26, and brain herniation on admission CT head were all associated with worse GOS scores at all time points. Excluding those who died, functional improvement occurred regardless of admission GCS score (p < 0.05). The overall mortality rate for the cohort was 21%.CONCLUSIONSGood functional outcomes were achieved in this population of severe penetrating brain injury in those who survived their initial resuscitation. The mortality rate was lower than observed in civilian cohorts.
