- Previously unknown N-acyl derivatives of 1,2,3-triazole chalcones have been prepared by the acylation of the potassium salts of 4-(3-oxo-3-phenylprop-1-en-1-yl)-5-phenyl-1,2,3-triazolides with carboxylic acid chlorides. The introduction of theN-acyl residue into the heterocyclic moiety of 1-aryl-3-(1H-1,2,3-triazol-4-yl)prop-2-en-1-ones has been shown to afford compounds with antibacterial activity.

- In older patients with Parkinson’s disease (PD), the use of dopamine agonists (DA) has been limited due to uncertainties related to their tolerability in spite of potential gains with the advent of longer acting or transdermal therapies. Comparative real-life data addressing the tolerability of DA therapy across age ranges are currently sparse. This study addressed the tolerability (Shulman criteria, continued intake of DA therapy for at least 6 months) in PD patients across several European centres treated with long-acting and transdermal DA (Rotigotine skin patch, Ropinirole extended release, or Pramipexole prolonged release) as part of routine clinical care in younger and older PD patients. A medical record-based retrospective data capture and clinical interview-based follow-up survey of patients initiating or initiated on DA treatment (short and long acting) in a real-life setting. 425 cases were included [mean age 68.3 years (range 37–90), mean duration of disease 7.5 years (range 0–37), 31.5% older age (≥ 75 years of age)]. Tolerability was above 90% irrespective of age, with no significant differences between younger and older patients. Based on our findings, we suggest that long-acting/transdermal DA are tolerated in non-demented older patients, as well as in younger patients, however, with lower daily dose in older patients.

- Background IRL752 is a novel small-molecule compound that acts to regioselectively enhance norepinephrine, dopamine, and acetylcholine neurotransmission in the cerebral cortex. Objective The primary objective of the trial was to investigate the safety and tolerability of IRL752 in patients with Parkinson's disease and dementia. Methods Patients with Parkinson's disease and dementia were randomized to IRL752 or placebo treatment (3:1 ratio) for 28 days. The study drug was given as an adjunct treatment to the patients' regular stable antiparkinsonian medication. Dosing was individually titrated for 14 days after which the dose was kept stable for an additional 14 days. Results A total of 32 patients were randomized to treatment, and 29 patients completed the 4-week treatment. Adverse events were generally mild and transient and were mostly reported during the dose titration phase. There were 2 serious adverse events, and none of them were related to the experimental treatment. The average dose achieved in the stable dose phase was 600 mg daily, yielding a 2-hour postdose plasma concentration of about 4 mu M on day 28. Exploratory assessment of secondary outcomes indicated efficacy for symptoms and signs known to be poorly responsive to levodopa. Conclusions IRL752 appears to be safe and well tolerated for a 4-week treatment in patients with Parkinson's disease and dementia. (c) 2020 International Parkinson and Movement Disorder Society

- Background: Non-motor symptoms (NMS) in patients with dystonia have a relevant impact on health-related quality of life; however, a comprehensive easy to use NMS assessment tool for clinical bedside use is currently not available. Objective: The validated German version of the dystonia non-motor symptoms questionnaire (DNMSQuest) for assessing NMS in craniocervical dystonia is presented. Methods: The DNMSQuest in the German language was developed based on internationally recognized standards for intercultural adaptation of self-completed patient questionnaires. Translation of the original English questionnaire into the German language as well as back translation to English was carried out independently by four bilingual specialists in neurological movement disorders. In each case a consensus version accepted by each translator was created by another neurologist. The back translated English version was compared with the original English questionnaire for relevant linguistic and content discrepancies by a neurologist who was significantly involved in the development of the original questionnaire. The final German version was used in 130 patients with cervical dystonia and 48 healthy controls in an international, multicenter validation study. Results: An interculturally adapted validated version of the DNMSQuest in the German and English languages was developed for rapid bedside assessment and evaluation of NMS in cervical dystonia. Conclusion: The DNMSQuest successfully bridges the current gap of a validated disease-specific, patient self-administered, short, comprehensive questionnaire for NMS assessment in routine clinical practice in craniocervical dystonia. It is envisaged that this tool will be useful for the clinical practice and trials.

- Introduction: There is little information on the late stages of parkinsonism. Methods: We conducted a multicentre study in 692 patients with late stage parkinsonism in six European countries. Inclusion criteria were disease duration of ≥7 years and either Hoehn and Yahr stage ≥4 or Schwab and England score of 50 or less. Results: Average disease duration was 15.4 (SD 7.7) years and mean total UPDRS score was 82.7 (SD 22.4). Dementia according to MDS-criteria was present in 37% of patients. Mean levodopa equivalence dose was 874.1 (SD 591.1) mg/d. Eighty two percent of patients reported falls, related to freezing (16%) or unrelated to freezing (21% of patients) or occurring both related and unrelated to freezing (45%), and were frequent in 26%. Moderate-severe difficulties were reported for turning in bed by 51%, speech by 43%, swallowing by 16% and tremor by 11%. Off-periods occurred in 68% and were present at least 50% of the day in 13%, with morning dystonia occurring in 35%. Dyskinesias were reported by 45% but were moderate or severe only in 7%. Moderate-severe fatigue, constipation, urinary symptoms and nocturia, concentration and memory problems were encountered by more than half of participants. Hallucinations (44%) or delusions (25%) were present in 63% and were moderate-severe in 15%. The association with overall disability was strongest for severity of falls/postural instability, bradykinesia, cognitive score and speech impairment. Conclusion: These data suggest that current treatment of late stage parkinsonism in the community remains insufficiently effective to alleviate disabling symptoms in many patients.
