This study aimed to investigate the characteristics and prognosis of patients with alcoholic Marchiafava–Bignami disease (MBD), a rare neurological disorder commonly associated with chronic alcoholism, in Chongqing, China.

We conducted a retrospective analysis of clinical data from 21 alcoholic MBD patients treated at the First Affiliated Hospital of Chongqing University between 2012 and 2022.

The study included 21 patients with alcoholic MBD who had a mean age of 59 ± 9.86 years and an average drinking history of 35.48 ± 8.65 years. Acute onset was observed in 14 (66.7%) patients. The primary clinical signs observed were psychiatric disorders (66.7%), altered consciousness (61.9%), cognitive disorders (61.9%), and seizures (42.9%). Magnetic resonance imaging revealed long T1 and long T2 signal changes in the corpus callosum, with lesions predominantly found in the genu (76.2%) and splenium (71.4%) of the corpus callosum. The poor prognosis group demonstrated an increased incidence of altered consciousness (100% vs 50%, P = 0.044), pyramidal signs (80% vs 18.8%, P = 0.011), and pneumonia (100% vs 31.3%, P = 0.007). Patients with a longer drinking history (45.0 ± 10.0 years vs 32.69 ± 5.99 years, p = 0.008) and a lower thiamine dose (p = 0.035) had a poorer prognosis at 1 year.

This study identified altered consciousness, pyramidal signs, and pneumonia as predictors of a poor prognosis in patients with alcoholic MBD. A longer duration of alcohol consumption and inadequate thiamine supplementation were associated with a poorer prognosis.

For multiply recurrent glioma, options are few and choices are very limited. Etoposide in combination with carboplatin and/or bevacizumab has been evaluated in recurrent glioma with modest efficacy. This retrospective study describes the efficacy of etoposide monotherapy in adults with multiply recurrent diffuse glioma.

In this single center retrospective series, all adult patients with radiographically proven multiply recurrent diffuse glioma (WHO grade 2–4) treated with etoposide between 2016 and 2020 were evaluated. Progression-free survival (PFS) and overall survival (OS) after initiating etoposide were calculated for the total group and for different histologic tumor types. In addition, treatment-related toxicity was recorded.

Totally, 48 patients with a median age 43 years-old (range 24–78) were included. Etoposide was given as 3rd line of treatment in 18 patients (37.5%) and as 4th or 5th line of treatment in 30 patients (62.5%). The majority were diagnosed with a glioblastoma, WHO grade 4 (27, 56.3%). The median PFS was 8.6 weeks (95% confidence interval [CI]: 8.3–8.9). The median OS of the total population was 4.0 months (95% CI: 2.4–5.6). Patients with an oligodendroglioma had the best OS (median 13 months), compared to astrocytoma and glioblastoma, but the difference was not statistically significant (p = 0.15). Etoposide was stopped due to progression in the majority of the patients (81.3%). Only 1 patient had a grade 3 toxicity.

Etoposide is a well-tolerated chemotherapy in heavily pretreated patients with multiply recurrent glioma and could be considered when other options are not available. OS was 4 months after initiating etoposide.

Parkinson’s disease (PD) is a common chronic neurodegenerative condition. As a result of the COVID-19 pandemic, healthcare provision faced challenges worldwide. We aimed to explore how the COVID-19 pandemic changed healthcare experiences for people living with Parkinson’s disease (PwP) in Canada.

We conducted a national cross-sectional online survey about healthcare access for PwP in 2020. Participants (n = 298) were recruited through Parkinson Canada, the national patient association and its provincial partners, that advertised the study in a monthly newsletter. We used descriptive statistics and multivariate regression modelling to test associations of interest. A P < 0.05 was deemed statistically significant.

During the COVID-19 pandemic, PwP reported greater difficulty obtaining PD-related healthcare services and lesser satisfaction with healthcare provision compared to pre-pandemic experiences. Dissatisfaction with care was associated with the presence of barriers to access services, a lack of confidence in accessing services remotely, pre-pandemic care dissatisfaction, and difficulty in obtaining care during the COVID-19 pandemic. Unmet care needs were associated with a lack of confidence in accessing services remotely, dissatisfaction with pre-pandemic care, difficulty obtaining pre-pandemic care, and communication challenges.

Our results suggest that healthcare experiences for PwP significantly changed during the COVID-19 pandemic, with challenges in access to virtual care. Poorer pre-pandemic care experiences were amplified during the pandemic.

Carpal tunnel syndrome (CTS) is one of the most common extra-cardiac manifestations of wild-type transthyretin amyloidosis (wtATTR); however, the characteristics of CTS in this population remain poorly understood.

This retrospective cohort study reports findings from a single-centre experience of comprehensive neurological screening at the time of wtATTR diagnosis by nerve conduction studies (NCS) and neurologist assessment.

Seventy-nine patients underwent neurological screening, 73 (92%) males, mean age 79.2 ± 7.5 years. Seventy-four (94%) had electrodiagnostic findings of median neuropathy at the wrist (MNW), 37 (50%) of which had a prior diagnosis of CTS and 37 (50%) had a new diagnosis of MNW. Over half of wtATTR patients (42, 53%) had bilateral MNW on screening. Most with pre-existing CTS had bilateral disease (28, 76%) and underwent bilateral carpal tunnel release (CTR) (23, 62%) prior to screening. Twenty-one (19%) wrists had mild MNW, 43 (38%) moderate and 49 (43%) severe. Twenty-one (28%) wtATTR patients with MNW were asymptomatic, 10 of which (48%) had moderate disease. Nineteen (36%) wtATTR patients with symptomatic MNW had recurrent disease despite previous CTR. As a result of screening, 36 (68%) patients with symptomatic MNW were referred for CTR.

MNW is exceptionally common at the time of wtATTR diagnosis, affecting 94% of our patients. Most had severe, bilateral MNW on NCS. Some were asymptomatic, despite having moderate disease. The rate of recurrence following CTR was observed to be higher in wtATTR patients than the general population.

Traumatic spinal cord injuries (tSCI) are common, often leaving patients irreparably debilitated. Therefore, novel strategies such as nerve transfers (NT) are needed for mitigating secondary SCI damage and improving function. Although different tSCI NT options exist, little is known about the epidemiological and injury-related aspects of this patient population. Here, we report such characteristics to better identify and understand the number and types of tSCI individuals who may benefit from NTs.

Two peripheral nerve experts independently evaluated all adult tSCI individuals < 80 years old admitted with cervical tSCI (C1–T1) between 2005 and 2019 with documented tSCI severity using the ASIA Impairment Scale for suitability for NT (nerve donor with MRC strength ≥ 4/5 and recipient ≤ 2/5). Demographic, traumatic injury, and neurological injury variables were collected and analyzed.

A total of 709 tSCI individuals were identified with 224 (32%) who met the selection criteria for participation based on their tSCI level (C1–T1). Of these, 108 (15% of all tSCIs and 48% of all cervical tSCIs) were deemed to be appropriate NT candidates. Due to recovery, 6 NT candidates initially deem appropriate no longer qualified by their last follow-up. Conversely, 19 individuals not initially considered appropriate then become eligible by their last follow-up.

We found that a large proportion of individuals with cervical tSCI could potentially benefit from NTs. To our knowledge, this is the first study to detail the number of tSCI individuals that may qualify for NT from a large prospective database.
