Methods for informing people with amyotrophic lateral sclerosis/motor neuron disease of their diagnosis.

BACKGROUND: Amyotrophic lateral sclerosis (ALS), also known as motor neuron disease (MND), causes increasing physical impairment and disability. People with ALS/MND face huge physical challenges, and the diagnosis can be a source of great psychological distress for both people with ALS/MND and their carers. In such a context, how news of the diagnosis is broken is important. At present, there are no systematic reviews of methods for informing people with ALS/MND of their diagnosis. OBJECTIVES: To examine the effects and effectiveness of different methods for informing people of a diagnosis of amyotrophic lateral sclerosis/motor neuron disease (ALS/MND), including effects on the person's knowledge and understanding of their disease, its treatment, and care; and on coping and adjustment to the effects of ALS/MND, its treatment, and care. SEARCH METHODS: We searched the Neuromuscular Specialised Register, CENTRAL, MEDLINE, Embase, PsycINFO, and two trials registers (February 2022). We contacted individuals or organisations to locate studies. We contacted study authors to obtain additional unpublished data. SELECTION CRITERIA: We planned to include randomised controlled trials (RCTs) and quasi-RCTs of techniques for informing people with ALS/MND of their diagnosis. We planned to include adults (aged 17 years or over) with ALS/MND, according to the El Escorial criteria. DATA COLLECTION AND ANALYSIS: Three review authors independently reviewed the results of the search to identify RCTs, and three review authors identified non-randomised studies to include in the discussion section. We planned that two review authors would independently extract data, and three would assess the risk of bias in any included trials. MAIN RESULTS: We did not identify any RCTs that met our inclusion criteria. AUTHORS' CONCLUSIONS: There are no RCTs that evaluate different communication strategies for breaking the bad news for people diagnosed with ALS/MND. Focused research studies are needed to assess the effectiveness and efficacy of different communication methods.

Association of TNF-α polymorphism rs1800629 with multisomatoform disorder in a group of German patients and healthy controls: an explorative study.

INTRODUCTION: The etiology of multisomatoform disorder (MSD) is still largely unknown, but genetic factors seem to have an influence on pathogenesis. Pain is a major symptom of MSD and polymorphisms of different proinflammatory cytokines have been found associated with pain in former studies. Therefore, we presumed that cytokine polymorphisms could also be associated with MSD. PATIENTS AND METHODS: Groups of 148 MSD patients with pain as the leading clinical symptom and 149 age and gender matched healthy controls participated in this study. Nine cytokine polymorphisms were genotyped and statistically analyzed for associations with MSD. RESULTS: Allelic and genotypic associations were found for rs16944 (interleukin 1ß), rs1800629 (tumor necrosis factor) and rs909253 (lymphotoxin α). After correcting for multiple testing, the association of rs1800629 with MSD remained significant. The rare A-allele was correlated with MSD (p=0.007). DISCUSSION: Since the common G-allele of rs1800629 (TNFα) occurs much more often in the control group than in the MSD group it is assumed to be protective. Being carrier of the A-allele seems to be a risk factor for MSD.
