Background: Multiple system atrophy (MSA) is a rapidly progressive neurodegenerative disorder which causes early sustained disability and quality of life impairment. Recently, a self-reported questionnaire focusing on MSA-specific symptoms (Multiple System Atrophy Quality of Life questionnaire, MSA-QoL) was developed in the English language. This article reports the validation of the German translation of the MSA-QoL.
Methods: Translation of the MSA-QoL was implemented in a 3-tiered approach including a forward translation, a back translation and an independent review. For the validation study 38 consecutive patients with MSA according to the consensus criteria were recruited by the participating centers in a German-Austrian cohort. Data were analyzed using standard psychometric procedures.
Results: As determined by the independent review, the German translation of the MSA-QoL was classified as fully equivalent to the English version. The validation study confirmed good psychometric properties of the rating scale.
Conclusion: The German translation of the MSA-QoL was shown to be a reliable patient-reported rating scale to determine health-related quality of life in MSA patients.

Background: Non-communicable diseases (NCDs) are the leading cause of death globally, and many humanitarian crises occur in countries with high NCD burdens. Peer support is a promising approach to improve NCD care in these settings. However, evidence on peer support for people living with NCDs in humanitarian settings is limited.

Background: /aims. Pseudoxanthoma Elasticum (PXE, OMIM 264800) is an autosomal, recessive, metabolic disorder characterized by progressive ectopic calcification in the skin, the vasculature and Bruch's membrane. Variants in the ABCC6 gene are associated with low plasma pyrophosphate (PPi) concentration.

Background: Multiple myeloma (MM) represents the second most common hematological malignancy characterized by the infiltration of the bone marrow by plasma cells that produce monoclonal immunoglobulin. While the quality and length of life of MM patients have significantly increased, MM remains a hard-to-treat disease; almost all patients relapse. As MM is highly heterogenous, patients relapse at different times.

Background: Radiotherapy as a complement or an alternative to neurosurgery has a central role in the treatment of skull base grade I-II meningiomas. Radiotherapy techniques have improved considerably over the last two decades, becoming more effective and sparing more and more the healthy tissue surrounding the tumour. Currently, hypo-fractionated stereotactic radiotherapy (SRT) for small tumours and normo-fractionated intensity-modulated radiotherapy (IMRT) or proton-therapy (PT) for larger tumours are the most widely used techniques.

Alcoholic osteonecrosis of the femoral head (AIONFH) is caused by long-term heavy drinking, which leads to abnormal alcohol and lipid metabolism, resulting in femoral head tissue damage, and then pathological necrosis of femoral head tissue. If not treated in time in clinical practice, it will seriously affect the quality of life of patients and even require hip replacement to treat alcoholic femoral head necrosis. This study will confirm whether M2 macrophage exosome (M2-Exo) miR-122 mediates alcohol-induced BMSCs osteogenic differentiation, ultimately leading to the inhibition of femoral head necrosis.
