- Objective: Quantitative analysis of decision-making on therapeutic options in different sociocultural context in amyotrophic lateral sclerosis (ALS).Methods: ALS patients (n = 244) were consecutively recruited in Germany (n = 83), Poland (n = 83), and Sweden (n = 78) in a prospective cross-cultural study (www.NEEDSinALS.com). They were interviewed on preferences for therapeutic techniques including invasive (IV) and non-invasive ventilation (NIV), as well as percutaneous endoscopic gastrostomy (PEG) and on hypothetical termination of these using quantitative questions. Using standardized questionnaires, religiousness, personal values, quality of life, and depressiveness were assessed.Results: NIV was most frequently used in Germany and PEG in Sweden. Swedish patients were most liberal on initiation and termination of PEG, NIV and IV. Polish patients were mostly undecided and were least likely to consider discontinuing supportive management. Current use was partly associated with age, gender and state of physical function; also, financial support explained some variance. Future preferences on therapeutic options from the patient’s perspective were also closely associated with cultural factors. The more oriented towards traditional and conservative values, the less likely patients were to decide for invasive therapeutic devices (IV, PEG), the least likely to have ideations to discontinue any device and the more likely to have an undecided attitude.Conclusions: Current use of therapeutic options is determined by medical condition in analogy to clinical guidelines. For future considerations, other factors such as cultural background are crucial, yielding hurdles to be regarded in the implementation of advanced directives in a multicultural environment.

- Objective: This is an observational study on well-being and end-of-life preferences in patients with amyotrophic lateral sclerosis (ALS) in the locked-in state (LIS) in a Polish sample within the EU Joint Programme-Neurodegenerative Disease Research study NEEDSinALS (NEEDSinALS.com).Methods: In this cross-sectional study, patients with ALS in LIS (n = 19) were interviewed on well-being (quality of life, depression) as a measure of psychosocial adaptation, coping mechanisms, and preferences towards life-sustaining treatments (ventilation, percutaneous endoscopic gastroscopy) and hastened death. Also, clinical data were recorded (ALS Functional Rating Scale-revised version). Standardized questionnaires (Anamnestic Comparative Self-Assessment [ACSA], Schedule for the Evaluation of Individual Quality of Life-Direct Weighting (SEIQoL-DW), ALS Depression Inventory-12 items [ADI-12], schedule of attitudes toward hastened death [SAHD], Motor Neuron Disease Coping Scale) were used, which were digitally transcribed; answers were provided via eye-tracking control. In addition, caregivers were asked to judge patients' well-being.Results: The majority of patients had an ACSA score >0 and a SEIQoL score >50% (indicating positive quality of life) and ADI-12 <29 (indicating no clinically relevant depression). Physical function did not reflect subjective well-being; even more, those with no residual physical function had a positive well-being. All patients would again choose the life-sustaining techniques they currently used and their wish for hastened death was low (SAHD <10). Caregivers significantly underestimated patient's well-being.Interpretation: Some patients with ALS in LIS maintain a high sense of well-being despite severe physical restrictions. They are content with their life-sustaining treatments and have a strong will to live, which both may be underestimated by their families and public opinion.

Neurofilaments in the diagnosis of motoneuron diseases : a prospective study on 455 patients

- Objectives Biomarkers for the diagnosis of motoneuron diseases (MND) are urgently needed to improve the diagnostic pathway, patient stratification and monitoring. The aim of this study was to validate candidate markers for MND in cerebrospinal fluid (CSF) and specify cut-offs based on large patient cohorts by especially considering patients who were seen under the initial differential diagnosis (MND mimics). Methods In a prospective study, we investigated CSF of 455 patients for neurofilament light chain (NfL), phosphorylated heavy chain (pNfH), tau protein (Tau) and phospho-tau protein (pTau). Analysed cohorts included patients with apparently sporadic and familial amyotrophic lateral sclerosis (ALS) and primary lateral sclerosis (PLS) (MND, n=253), MND mimics (n=85) and neurological control groups. Cut-off values were specified, and diagnostic performance and correlation with progression were analysed. Results Nfs were significantly higher in the MND group compared to the control groups, whereas Tau and pTau did not differ. At a cut-off level of 2200 pg/mL for NfL, a 77% diagnostic sensitivity (CI 71% to 82%), 85% specificity (CI 79% to 90%) and 87% positive predictive value (PPV) (CI 81% to 91%) were achieved. For pNfH, we calculated 83% sensitivity (CI 78% to 88%), 77% specificity (CI 71% to 83%) and 82% PPV (CI 77% to 86%) at 560 pg/mL. There were no significant differences between sporadic and genetic ALS or PLS. Nf levels were elevated at early disease stage, and correlated moderately with MND progression and duration. Conclusions Neurofilaments in CSF have a high relevance for the differential diagnosis of MNDs and should be included in the diagnostic work-up of patients. Their value as prognostic markers should be investigated further.

Existential decision-making in a fatal progressive disease : how much do legal and medical frameworks matter?

Journal article (peer-reviewed)abstract
- Background: Healthcare legislation in European countries is similar in many respects. Most importantly, the framework of informed consent determines that physicians have the duty to provide detailed information about available therapeutic options and that patients have the right to refuse measures that contradict their personal values. However, when it comes to end-of-life decision-making a number of differences exist in the more specific regulations of individual countries. These differences and how they might nevertheless impact patient’s choices will be addressed in the current debate.Main text: In this article we show how the legal and medical frameworks of Germany, Poland and Sweden differ with regard to end-of-life decisions for patients with a fatal progressive disease. Taking Amyotrophic Lateral Sclerosis (ALS) as an example, we systematically compare clinical guidelines and healthcare law, pointing out the country-specific differences most relevant for existential decision-making. A fictional case report discusses the implications of these differences for a patient with ALS living in either of the three countries. Patients with ALS in Germany, Poland and Sweden are confronted with a similar spectrum of treatment options. However, the analysis of the normative frameworks shows that the conditions for making existential decisions differ considerably in Germany, Poland and Sweden. Specifically, these differences concern (1) the legal status of advance directives, (2) the conditions under which life-sustaining therapies are started or withheld, and (3) the legal regulations on assisted dying.Conclusion: According to the presented data, regulations of terminating life-sustaining treatments and the framework of “informed consent” are quite differently understood and implemented in the legal setting of the three countries. It is possible, and even likely, that these differences in the legal and medical frameworks have a considerable influence on existential decisions of patients with ALS.
