RESUMEN
BACKGROUND: Up to 70% of people diagnosed with upper gastrointestinal (GI) tract or hepato-pancreato-biliary (HPB) cancers experience substantial reductions in quality of life (QoL), including high distress levels, pain, fatigue, sleep disturbances, weight loss and difficulty swallowing. With few advocacy groups and support systems for adults with upper GI or HPB cancers (i.e. pancreas, liver, stomach, bile duct and oesophageal) and their carers, online supportive care programs may represent an alternate cost-effective mechanism to support this patient group and carers. iCare is a self-directed, interactive, online program that provides information, resources, and psychological packages to patients and their carers from the treatment phase of their condition. The inception and development of iCare has been driven by consumers, advocacy groups, government and health professionals. The aims of this study are to determine the feasibility and acceptability of iCare, examine preliminary efficacy on health-related QoL and carer burden at 3- and 6-months post enrolment, and the potential cost-effectiveness of iCare, from health and societal perspectives, for both patients and carers. METHODS AND ANALYSIS: A Phase II randomised controlled trial. Overall, 162 people with newly diagnosed upper GI or HPB cancers and 162 carers will be recruited via the Upper GI Cancer Registry, online advertisements, or hospital clinics. Patients and carers will be randomly allocated (1:1) to the iCare program or usual care. Participant assessments will be at enrolment, 3- and 6-months later. The primary outcomes are i) feasibility, measured by eligibility, recruitment, response and attrition rates, and ii) acceptability, measured by engagement with iCare (frequency of logins, time spent using iCare, and use of features over the intervention period). Secondary outcomes are patient changes in QoL and unmet needs, and carer burden, unmet needs and QoL. Linear mixed models will be fitted to obtain preliminary estimates of efficacy and variability for secondary outcomes. The economic analysis will include a cost-consequences analysis where all outcomes will be compared with costs. DISCUSSION: iCare provides a potential model of supportive care to improve QoL, unmet needs and burden of disease among people living with upper GI or HPB cancers and their carers.

This cohort study aimed to characterize the prodromal phase of hereditary spastic paraplegia type 4 (SPG4) using biomarkers and clinical signs and symptoms that develop before manifest gait abnormalities. Fifty-six first-degree relatives at risk of developing SPG4 underwent blinded genotyping and standardized phenotyping, including the Spastic Paraplegia Rating Scale (SPRS), complicating symptoms, non-motor affection, Three-Minute Walk, and neurophysiological assessment. Automated MR image analysis was used to compare volumetric properties. CSF of 33 probands was analysed for neurofilament light chain (NfL), tau, and amyloid-ß (Aß). Thirty participants turned out to be SPAST mutation carriers, whereas 26 did not inherit a SPAST mutation. Increased reflexes, ankle clonus, and hip abduction weakness were more frequent in prodromal mutation carriers but were also observed in non-mutation carriers. Only Babinski's sign differentiated reliably between the two groups. Timed walk and non-motor symptoms did not differ between groups. Whereas most mutation carriers had total SPRS scores of 2 points or more, only two non-mutation carriers reached more than 1 point. Motor evoked potentials revealed no differences between mutation and non-mutation carriers. We found NfL but not tau or Aß to rise in CSF of mutation carriers when approaching the time point of predicted disease manifestation. Serum NfL did not differ between groups. Volumetric MRI analyses did not reveal group differences apart from a smaller cingulate gyrus in mutation carriers. This study depicts subtle clinical signs which develop before gait abnormalities in SPG4. Long-term follow-up is needed to study the evolution of SPG4 in the prodromal stage and conversion into manifest disease. NfL in CSF is a promising fluid biomarker that may indicate disease activity in prodromal SPG4 but needs further evaluation in longitudinal studies.

BACKGROUND: People living with cancer, or carers who are from lesbian, gay, bisexual, transgender, queer, intersex or asexual (LGBTQIA+) communities experience unique information and support needs. Accessible technology-based resources providing tailored support are required to promote wellbeing, however this is a growing area of research requiring further investigation. The purpose of this study was to explore the experiences of healthcare services among people living with cancer, and their carers, who belong to sexual or gender diverse communities (LGBTQIA+), and identify how smartphone applications (apps) could support people from LGBTQIA + communities. METHODS: This was a qualitative descriptive study where people living with cancer or carers from LGBTQIA + communities participated in phone interviews. Participants were recruited across Australia via social media advertisements, LGBTQIA + medical practices, and cancer advocacy groups. Participants were asked questions about their experiences, and were provided with screenshots of an existing app and asked to provide feedback on content and inclusiveness. Transcripts were coded and codes grouped together to form similar and concepts. Inductive and deductive analyses were used to create themes. RESULTS: 13 patients (mean age 56 (SD:13)), and three carers (mean age 64 (SD:19)) completed phone interviews. The majority of participants identified their gender as female (patients n = 9, carers 3), and their sexuality as gay or lesbian (patients n = 10, carers n = 3). Four themes were created: (1) navigating disclosure in healthcare, described emotional challenges surrounding disclosure; (2) the power of positive experiences with clinicians, described positive interactions and gaps in care from clinicians; (3) impact of gender and sexuality on informal support, outlined support received from informal network and gaps in support, and; (4) opportunities to increase inclusivity in smartphone apps, generated ideas on how apps can be tailored to meet needs identified. CONCLUSION: Disclosure of gender or sexuality, and interactions with clinicians had the potential to impact participants' experience of cancer care. Gaps in informal networks pointed at how to better support LGBTQIA + communities, and identified opportunities for inclusion in an app that will be tailored and trialled for this community. Future work should focus on addressing systems-level processes in acknowledging and supporting priority groups affected by cancer.

OBJECTIVE: Evaluate accessibility, effectiveness, acceptability and efficiency of a student- assisted teleaudiology model of care in a regional hospital in Queensland, Australia. DESIGN: Prospective mixed method service evaluation study. STUDY SAMPLE: Demographic, service and satisfaction data were collected from 233 patients (children aged ≥5 and adults) who received teleaudiology assessment. Satisfaction data was collected from 27 hospital clinic staff (medical, nursing and clinic assistants) and 28 university audiology clinical educator participants. Experience and satisfaction data were collected from 16 teleaudiology clinic university students. Quantitative data was analysed using SPSS software. Qualitative data were analysed using inductive content analysis. RESULTS: Following introduction of the teleaudiology service in 2017 and evaluation during the first 6 months, 95% of patients were able to access audiology assessments on the same day as their Ear, Nose and Throat appointments. New referrals to the service were seen within a month. The audiology assessment battery was completed 95% of the time within an average of 33 minutes by the end of the study period. Patients, hospital and university staff and students reported high satisfaction with their experiences of teleaudiology, including its convenience and efficiency. CONCLUSIONS: A student-assisted teleaudiology model of care can deliver accessible, effective, and efficient services with high levels of satisfaction by participants.

BACKGROUND: Nerve injuries are a frequent problem in routine clinical practice and require intensive interdisciplinary care. OBJECTIVE: The current status of imaging to confirm the diagnosis of nerve injuries is described. The role of high-resolution ultrasound and magnetic resonance imaging (MRI) in the diagnostics and follow-up of peripheral nerve injuries is elaborated. MATERIAL AND METHODS: Review of the current state of imaging to confirm the diagnosis of nerve injuries. RESULTS: Depending on the suspected site of damage, the primary domain of magnetic resonance (MR) imaging (MR neurography) is injuries in the region of the spine, nerve roots, brachial plexus and lumbar plexus, pelvis and proximal thigh. In contrast, in other peripheral nerve lesions of the extremities the advantages of high-resolution nerve ultrasound in a dynamic setting predominate. The MR neurography is indicated here, especially in the frequent bottleneck syndromes and only in very isolated and selected cases. CONCLUSION: In addition to a correct anatomical assignment, the timely decision for a possible intervention and the appropriate concomitant treatment are an important basis for a favorable prognosis of nerve injuries. Imaging techniques should therefore be used early in the diagnostics and follow-up controls of peripheral nerve injuries.

BACKGROUND: Diagnosis and treatment of patients with immune-mediated neuropathies is challenging due to the heterogeneity of the diseases. OBJECTIVES: To assess similarities and differences in the current care of patients with immune-mediated polyneuropathies in specialized centers in Germany within the German neuritis network "Neuritis Netz". MATERIAL AND METHODS: We conducted a cross-sectional survey of nine neurological departments in Germany that specialize in the care of patients with immune-mediated neuropathies. We assessed the diagnosis, the approach to diagnostic work-up and follow-up, typical symptoms at manifestation and progression of the disease, and treatment data. RESULTS: This report includes data from 1529 patients per year treated for immune-mediated neuropathies, of whom 1320 suffered from chronic inflammatory demyelinating polyneuropathy (CIDP). Diagnostic work-up almost always included nerve conduction studies, electromyography, and lumbar puncture in accordance with current guidelines. The use of ultrasound, biopsy, and MRI varied. The most important clinical parameter for therapy monitoring in all centers was motor function in the clinical follow-up examinations. A wide range of different immunosuppressants was used for maintenance therapy in about 15% of patients. CONCLUSIONS: These data provide important epidemiological insights into the care of patients with immune-mediated neuropathies in Germany. The further development of specific recommendations for treatment and follow-up examinations is necessary to ensure a uniform standard of patient care. This effort is greatly facilitated by a structured collaboration between expert centers such as Neuritis Netz.

Background and Objectives: Immune checkpoint inhibitors (ICIs) have enriched tumor therapy, improving overall survival. Immunotherapy adverse events (irAEs) occur in up to 50% of patients and also affect the peripheral nervous system. The exact pathomechanism is unclear; however, an autoimmune process is implicated. Thus, the clinical evaluation of irAEs in the peripheral nervous system is still demanding. We retrospectively analyzed nerve ultrasound (NU) data of polyneuropathies (PNPs) secondary to checkpoint inhibitors. Materials and Methods: NU data of patients with PNP symptoms secondary to ICI therapy were retrospectively analyzed using the Ultrasound Pattern Sum Score (UPSS) as a quantitative marker. Our findings were compared with a propensity score match analysis (1:1 ratio) to NU findings in patients with chronic inflammatory demyelinating polyneuropathy (CIDP) and chemotherapy-associated PNP patients. Results: In total, 10 patients were included (4 female, mean age 66 ± 10.5, IQR 60-77), where NU was performed in 80%. The UPSS obtained ranged from 0 to 5 (mean 2 ± 1.6, IQR 1-2.5). The morphological changes seen in the NUs resembled sonographic changes seen in chemotherapy-associated PNP (n = 10, mean UPSS 1 ± 1, IQR 0-2) with little to no nerve swelling. In contrast, CIDP patients had a significantly higher UPSS (n = 10, mean UPSS 11 ± 4, IQR 8-13, p < 0.0001). Conclusions: Although an autoimmune process is hypothesized to cause peripheral neurological irAEs, NU showed no increased swelling as seen in CIDP. The nerve swelling observed was mild and comparable to ultrasound findings seen in chemotherapy-associated PNP.

INTRODUCTION/AIMS: Hands-on supervised training is essential for learning diagnostic ultrasound. Unfortunately, the coronavirus disease 2019 (COVID-19) pandemic led to suspension of in-person training courses. As a result, many hands-on training courses were converted into virtual courses during the pandemic. Several reports regarding virtual ultrasound courses exist, but none has addressed virtual neuromuscular ultrasound courses, their design, or participants' views of this form of training. Therefore, the aims of this study were: (1) to determine the feasibility of conducting virtual neuromuscular ultrasound courses during the COVID-19 pandemic; and (2) to report the positive and negative aspects of the courses through the analyses of the responses of post-course surveys. METHODS: Two virtual neuromuscular ultrasound courses, basic and intermediate level, were conducted by the Egyptian Neuromuscular Ultrasound society during August 2020. Post-course, the attendees were directed to an electronic survey that consisted of eight questions. Ninety-three responses (23.8%) were obtained from the survey of the basic course and 156 responses (44.4%) were obtained from the survey of the intermediate course. RESULTS: Ninety-eight percent of the respondents to basic course surveys, and 100% of the respondents to the intermediate course survey found the courses useful or very useful. DISCUSSION: This report demonstrates the utility of virtual neuromuscular ultrasound courses for those participants willing to respond to a survey and describes a proposed design for such courses. Although hands-on supervised ultrasound training is ideal, virtual courses can be useful alternatives to in-person training when in-person interaction is restricted.

BACKGROUND: Web-based mindfulness programs may be beneficial in improving the well-being outcomes of those living with chronic illnesses. Adherence to programs is a key indicator in improving outcomes; however, with the digitization of programs, it is necessary to enhance engagement and encourage people to return to digital health platforms. More information is needed on how engagement strategies have been used in web-based mindfulness programs to encourage adherence. OBJECTIVE: The aim of this study is to develop a list of engagement strategies for web-based mindfulness programs and evaluate the impact of engagement strategies on adherence. METHODS: A narrative systematic review was conducted across the MEDLINE Complete, CINAHL Complete, APA PsycINFO, and Embase databases and followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines. Articles were screened using the population, intervention, comparator, and outcome framework. Adults aged >18 years with chronic health conditions were included in the study. Mindfulness interventions, including those in combination with mindfulness-based cognitive therapy, delivered on the web through the internet or smartphone technology were included. Interventions lasted at least 2 weeks. Studies with a randomized controlled trial design or a pilot randomized controlled trial design were included. Engagement strategies, including web-based program features and facilitator-led strategies, adherence, and retention, were included. RESULTS: A total of 1265 articles were screened, of which 19 were relevant and were included in the review. On average, 70.98% (2258/3181) of the study participants were women with a mean age of 46 (SD 13) years. Most commonly, mindfulness programs were delivered to people living with mental health conditions (8/19, 42%). Of the 19 studies, 8 (42%) used only program features to encourage adherence, 5 (26%) used facilitator-led strategies, and 6 (32%) used a combination of the two. Encouraging program adherence was the most common engagement strategy used, which was used in 77% (10/13) of the facilitator-led studies and 57% (8/14) of the program feature studies. Nearly two-thirds (63%) of the studies provided a definition of adherence, which varied between 50% and 100% completion across studies. The overall mean participant compliance to the mindfulness programs was 56% (SD 15%). Most studies (10/19, 53%) had a long-term follow-up, with the most common follow-up period being 12 weeks after intervention (3/10, 30%). After the intervention, the mean retention was 78% (SD 15%). CONCLUSIONS: Engagement strategies in web-based mindfulness programs comprise reminders to use the program. Other features may be suitable for encouraging adherence to interventions, and a facilitator-led component may result in higher retention. There is variance in the way adherence is measured, and intervention lengths and follow-up periods are inconsistent. More thorough reporting and a standardized framework for measuring adherence are needed to more accurately assess adherence and engagement strategies.

PURPOSE: Peripheral nerve sheath tumors are hallmark findings in neurofibromatosis types 1 and 2. With increasing size, they typically lead to neurological symptoms, and NF1 patients have a lifetime risk of 8-13% for developing malignant peripheral nerve sheath tumors. Medical imaging is therefore highly needed for early detection and exact localization of symptomatic or potentially malignant tumors. This review will give an overview of the ultrasound characteristics of peripheral nerve sheath tumors and findings in patients with neurofibromatosis types 1 and 2. METHODS: A systematic search of electronic databases, reference lists, and unpublished literature was conducted including the keywords "schwannoma," "neurofibroma," "neurofibromatosis," "benign and malignant peripheral nerve sheath tumor." RESULTS: The high-resolution allows a clear analysis of tumor echotexture, definition of margins, and the relation to the parent nerve. The use of color duplex/Doppler and contrast agent adds valuable information for the differentiation of benign and malignant tumors. CONCLUSION: High-resolution ultrasound is a well-established, non-invasive, and easily repeatable first-line tool in diagnostic procedures of soft tissue tumors.

BACKGROUND: Half of all diabetics are affected by a diabetic neuropathy. Microangiopathy, dysfunctional Schwann cell interactions, accumulation of toxic metabolites, and inflammatory processes all contribute to nerve damage. OBJECTIVE: Overview and perspectives of the pathophysiology as well as the current and future treatment implications. METHODS: Literature search (1990-2020). RESULTS: Clinically predominant are sensory and autonomic symptoms; however, muscle weakness can occur as well. Complications such as unrecognized myocardial infarctions and the diabetic foot syndrome are potentially life-threatening and can cause major disability. The pathophysiology of neuropathies in type 1 and type 2 diabetes mellitus differs due to additional risk factors of the metabolic syndrome. To reduce the risk of neuropathy, an intensive insulin therapy is superior compared to the conventional insulin therapy. Oral antidiabetic drugs should be chosen based on individual risk profiles. Metformin can cause an iatrogenic vitamin B12 deficiency. In the treatment of neuropathic pain, the calcium channel blocker pregabalin has the highest recommendation level. The tricyclic antidepressant amitriptyline is considered to be equally effective, but it is contraindicated in autonomic dysregulation and cognitive impairment. Alternatively, the serotonin-norepinephrine reuptake inhibitor duloxetine is approved for the symptomatic treatment of diabetic neuropathies. Controversially discussed medications include alpha-lipoic acid, epalrestat, and Lserine. CONCLUSION: The diabetic neuropathy is frequent and causes severe complications. A good understanding of the underlying pathophysiology can contribute to the development of novel treatment strategies in the future.

Nerve lesions are a frequent and often neglected problem in the daily routine of hospitals and clinical work and necessitate an intensive interdisciplinary treatment. In addition to correct anatomical allocation, the correct timing of the appropriate diagnostics, the timely decision for a possible intervention and the appropriate accompanying treatment are important prerequisites for a favorable prognosis. The basic diagnostics are, above all, neurography and electromyography after a sound clinical examination and documentation. In recent years both high-resolution ultrasound imaging and magnetic resonance imaging (MRI) of nerves have increasingly become established as indispensable diagnostic tools. In addition to describing the electrophysiological and sonographic principles, this article provides insights into surgical procedures, interdisciplinary cooperation and practical approaches.

PURPOSE: Sporadic mononeuropathies without trauma or compression are challenging to diagnose. Nerve ultrasound has recently proven its usefulness in the diagnosis of traumatic neuropathies, tumors and polyneuropathies. However, its role in mononeuropathies currently remains unclear. We describe ultrasonography follow-up results in 12 patients with suggested spontaneous, monophasic mononeuritis without signs of generalization. MATERIALS AND METHODS: Nerve conduction studies (NCS), ultrasonography of the affected nerves and the contralateral side, laboratory analysis, and if possible magnetic resonance imaging (MRI) of the affected nerves were established in all patients at onset. In one patient, additive nerve biopsy was performed. In all patients, ultrasonography was repeated after immunotherapy. RESULTS: An infectious pathogen of neuritis was not found in any patient. All but one patient showed predominant axonal nerve damage in NCS, whereas ultrasonography and MRI revealed fascicular and/or overall cross-sectional area (CSA) enlargement or T2 hyperintensity of the affected nerve segments, suggesting an inflammatory background of the neuropathy. Most patients showed significant clinical amelioration of symptoms under treatment (75.0â%) and consequently a decrease in CSA/fascicle enlargement over time (77.8â%). CONCLUSION: Ultrasonography and MRI of the nerves revealed enlargement in patients with mononeuropathy of axonal NCS pattern of unknown origin. Ultrasonography can facilitate the therapeutic decision for immunotherapy. Next to nerve trauma, nerve tumors and nerve entrapments, ultrasonography reliably shows nerve enlargement in the case of inflammation and therefore could further enrich neurophysiology. Nerve imaging might serve as a follow-up tool by observing a decrease in nerve enlargement and improved function.

BACKGROUND AND PURPOSE: Specific coagulation assays for non-vitamin K antagonist oral anticoagulants (NOAC) are relatively slow and often lack availability. Although specific point-of-care tests (POCT) are currently not available, NOAC are known to affect established coagulation POCT. This study aimed at determining the diagnostic accuracy of the CoaguChek POCT to rule out relevant concentrations of rivaroxaban, apixaban, and dabigatran in real-life patients. METHODS: We consecutively enrolled 60 ischemic stroke patients newly started on NOAC treatment and obtained blood samples at 6 prespecified time points. Samples were tested using the CoaguChek POCT, laboratory-based coagulation assays (prothrombin time and activated partial thromboplastin time, anti-Xa test and Hemoclot), and liquid chromatography-tandem mass spectrometry for direct determination of NOAC concentrations. RESULTS: Three hundred fifty-six blood samples were collected. The CoaguChek POCT strongly correlated (r=0.82 P<0.001) with rivaroxaban concentrations but did not accurately detect dabigatran or apixaban. If used to estimate the presence of low rivaroxaban concentrations, POCT was superior to predictions based on normal prothrombin time and activated partial thromboplastin time values even if sensitive reagents were used. POCT-results≤1.0 predicted rivaroxaban concentrations<32 and <100 ng/mL with a specificity of 90% and 96%, respectively. CONCLUSIONS: If anti-Xa test is not available, we propose the use of the CoaguChek POCT to guide thrombolysis decisions after individual risk assessment in rivaroxaban-treated patients having acute ischemic stroke.

BACKGROUND: Multimedia interventions may play an important role in improving patient care and reducing the time constraints of patient-clinician encounters. The "MyStay Cardiac" multimedia resource is an innovative program designed to be accessed by adult patients undergoing cardiac surgery. OBJECTIVE: The purpose of this study was to evaluate the uptake of the MyStay Cardiac both during and following the COVID-19 pandemic. METHODS: A prospective observational study design was used that involved the evaluation of program usage data available from the digital interface of the multimedia program. Data on usage patterns were analyzed for a 30-month period between August 2020 and January 2023. Usage patterns were compared during and following the lifting of COVID-19 pandemic restrictions. Uptake of the MyStay Cardiac was measured via the type and extent of user activity data captured by the web-based information system. RESULTS: Intensive care unit recovery information was the most accessed information, being viewed in approximately 7 of 10 usage sessions. Ward recovery (n=124/343, 36.2%), goal (n=114/343, 33.2%), and exercise (n=102/343, 29.7%) information were routinely accessed. Most sessions involved users exclusively viewing text-based information (n=210/343, 61.2%). However, in over one-third of sessions (n=132/342, 38.5%), users accessed video information. Most usage sessions occurred during the COVID-19 restriction phase of the study (August 2020-December 2021). Sessions in which video (P=.02, phi=0.124) and audio (P=.006, phi=0.161) media were accessed were significantly more likely to occur in the restriction phase compared to the postrestriction phase. CONCLUSIONS: This study found that the use of digital multimedia resources to support patient education was well received and integrated into their practice by cardiac nurses working in acute care during the COVID-19 pandemic. There was a pattern for greater usage of the MyStay Cardiac during the COVID-19 pandemic when access to the health service for nonfrontline, essential workers was limited.

BACKGROUND: Digital health literacy has emerged as a critical skill set to navigate the digital age. OBJECTIVE: This review sought to broadly summarize the literature on associations between digital health literacy and (1) sociodemographic characteristics, (2) health resource use, and (3) health outcomes in the general population, patient groups, or parent or caregiver groups. METHODS: A rapid review of literature published between January 2016 and May 2022 was conducted through a search of 4 web-based databases. Articles were included on the basis of the following keywords: "measured digital health literacy," "digital literacy," "ehealth literacy," "e-health literacy," "electronic health literacy," or "internet health literacy" in adult populations; participants were from countries where English was the primary language; studies had to be cross-sectional, longitudinal, prospective, or retrospective, and published in English. RESULTS: Thirty-six articles met the inclusion criteria. Evidence on the associations between digital health literacy and sociodemographic characteristics varied (27/36, 75% included studies), with higher education (16/21, 76.2% studies that examined the association) and younger age (12/21, 57.1% studies) tending to predict higher digital health literacy; however, other studies found no associations. No differences between genders were found across the majority of studies. Evidence across ethnic groups was too limited to draw conclusions; some studies showed that those from racial and ethnic minority groups had higher digital health literacy than White individuals, while other studies showed no associations. Higher digital health literacy was associated with digital health resource use in the majority of studies (20/36, 55.6%) that examined this relationship. In addition, higher digital health literacy was also associated with health outcomes across 3 areas (psychosocial outcomes; chronic disease and health management behaviors; and physical outcomes) across 17 included studies (17/36, 47.2%) that explored these relationships. However, not all studies on the relationship among digital health literacy and health resource use and health outcomes were in the expected direction. CONCLUSIONS: The review presents mixed results regarding the relationship between digital health literacy and sociodemographic characteristics, although studies broadly found that increased digital health literacy was positively associated with improved health outcomes and behaviors. Further investigations of digital health literacy on chronic disease outcomes are needed, particularly across diverse groups. Empowering individuals with the skills to critically access and appraise reliable health information on digital platforms and devices is critical, given emerging evidence that suggests that those with low digital health literacy seek health information from unreliable sources. Identifying cost-effective strategies to rapidly assess and enhance digital health literacy capacities across community settings thus warrants continued investigation.
RESUMEN
BACKGROUND: To specify peripheral nerve affection in autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS) by correlating high-resolution nerve ultrasound and nerve conduction studies. METHODS: We assessed a cohort of 11 ARSACS patients with standardized nerve conduction studies and high-resolution ultrasound of peripheral nerves and compared nerve ultrasound findings to a healthy control group matched for age, sex, size and weight. RESULTS: Mean age of patients was 39.0 (± 14.1) years and disease duration at assessment 30.6 (± 12.5) years. All patients presented with a spasticity, ataxia and peripheral neuropathy. Neuropathy appeared to be primarily demyelinating in 9/11 cases and was not classifiable in 2/11 cases due to not evocable potentials. Nerve ultrasound revealed a normal ultrasound pattern sum score (UPSS) in each ARSACS patient and no significant nerve enlargement compared to the control group. CONCLUSIONS: Peripheral neuropathy in ARSACS showed primarily demyelinating rather than axonal characteristics and presented without nerve enlargement. As demyelinating neuropathies do commonly present enlarged nerves we recommend further genetic testing of the SACS gene in patients who present with this combination of demyelinating neuropathy without nerve enlargement. ARSACS cases that initially presented only with neuropathy without spasticity or ataxia and therefore were misdiagnosed as Charcot-Marie-Tooth disease are supporting this suggestion.
