Commercially available anti-CD19 chimeric antigen receptor T cells (CARΤ cells) have offered long-term survival to a constantly expanding patient population. Given that novel toxicities including cytokine release syndrome (CRS) and neurotoxicity (ICANS) have been observed, we aimed to document the safety and toxicity of this treatment in a real-world study. We enrolled 31 adult patients referred to our center for CAR T therapy.

In this paper, we demonstrate the potential of a knowledge-driven framework to improve the efficiency and effectiveness of care through remote and intelligent assessment. More specifically, we present a rule-based approach to detect health related problems from wearable lifestyle sensor data that add clinical value to take informed decisions on follow-up and intervention. We use OWL 2 ontologies as the underlying knowledge representation formalism for modelling contextual information and high-level concepts and relations among them.

Unlabelled: The presence of comorbid insomnia and sleep apnea (COMISA) reduces the initial acceptance of continuous positive airway pressure (CPAP) therapy in 39-58% of patients with obstructive sleep apnea (OSA). Depressive disorders are reported in 5 to 63% of patients with OSA. Here we studied the co-occurrence of depression and insomnia in OSA patients and its impact on treatment acceptance in a real-life controlled trial.

Background: Chronic inflammatory demyelinating polyneuropathy (CIDP) is a rare immune-mediated disease of the peripheral nervous system characterized by motor weakness, sensory symptoms, areflexia, and specific electrophysiological findings. Rarely, Anti-Tumor Necrosis Factor-alpha (anti-TNFa) agents, which are used as a treatment for immune-mediated diseases, can cause neurological adverse effects on the central nervous system, as well as peripheral nervous system demyelination.

Case Report: We describe the case of a 63-year-old woman with ankylosing spondylitis who developed chronic inflammatory demyelinating polyneuropathy after infliximab initiation.

Background: The number of dementia training programs in hospital settings is steadily increasing. The way training sessions are designed influences the way the learning content is implemented in practice. To develop a successful training it is important to meet the needs of the target group; however, not much is known about staff preferences and expectations relevant to future dementia training programs in hospitals in Germany and Greece.

Canavan's disease (CD) is a hereditary leukodystrophy caused by mutations in the aspartoacylase gene (ASPA), leading to spongiform degeneration of the white matter and severe impairment of psychomotor development. We present the cases of two non-Jewish sisters with CD that have a milder and protracted clinical course compared to typical CD. MRI imaging revealed bilateral high-signal-intensity areas in the thalami and the internal capsule and MR spectroscopy showed typical findings for CD (a marked increase in N-acetylaspartate (NAA) levels).

Background: The inherited dysfibrinogenemias comprise rare congenital coagulation disorders which are clinically characterized by bleeding diathesis and, in occasional patients, by thrombotic tendency or combined bleeding-thrombotic events. In recent years, accumulating evidence suggested that fibrinogen has a critical role in the pathogenesis of neuroinflammatory disorders, including multiple sclerosis. We describe the presentation and long-term follow-up of a patient with inherited dysfibrinogenemia and concomitant clinical and laboratory evidence of demyelinating disease.

Background: It has been indicated that rotator cuff tears, especially large or massive ones, can cause suprascapular neuropathy. When such a diagnosis has been established, it is still unknown whether an arthroscopic release of the superior transverse scapular ligament during cuff repair can change the course of this neuropathy.

Methods/design: This is a single-center, double-blinded randomized controlled trial for which 42 patients with large or massive repairable rotator cuff tears and suprascapular neuropathy will be recruited and followed up at 6 and 12 months.

Miller-Fisher syndrome (MFS) is considered as a variant of the Guillain-Barre syndrome (GBS) and its characteristic clinical features are ophthalmoplegia, ataxia, and areflexia. Typically, it is associated with anti-GQ1b antibodies; however, a significant percentage (>10%) of these patients are seronegative. Here, we report a 67-year-old female patient who presented with the typical clinical features of MFS.

Background: As the population of older adults is growing, the interest in a simple way to detect characterize amnestic mild cognitive impairment (aMCI), a prodromal stage of Alzheimer's disease (AD), is becoming increasingly important. Serious game (SG) -based cognitive and motor performance profiles while performing everyday activities and dual-task walking (DTW) "motor signatures" are two very promising markers that can be detected in predementia states. We aim to compare the consistency, or conformity, of measurements made by a custom SG with DTW (NAV), a SG without DTW (DOT), neuropsychological measures and genotyping as markers for early detection of aMCI.
