Meta AnalysisPlasma creatinine and amyotrophic lateral sclerosis prognosis: a systematic review and meta-analysis.
Background: Plasma creatinine has been described as a prognostic biomarker for Amyotrophic Lateral Sclerosis (ALS), but with conflicting results in the literature. We performed a systematic review followed by a meta-analysis to address this question. Methods: We performed a systematic review of Pubmed, Embase and Cochrane databases and retrieved 14 distinct cohorts (19 studies) reporting results regarding the relationship between plasma creatinine and a clinical marker for ALS progression, notably ALSFRS (ALS Functional Rating Scale) and survival. ⋯ The overall quality of the studies was low mainly due to potential attrition bias, and several studies did not report analyzable results raising concern regarding a potential reporting bias. Conclusions: Plasma creatinine seems to be a promising prognostic biomarker for ALS. However, new studies with sound methodology and standardized criteria for the evaluation of ALS progression should be conducted to validate plasma creatinine as a clinical biomarker for ALS prognosis.

Randomized Controlled Trial Observational StudyPsychological distress and coping styles of caregivers of patients with amyotrophic lateral sclerosis: a longitudinal study.
Objectives: To assess psychological distress levels over time in caregivers of patients in the early stage of amyotrophic lateral sclerosis (ALS) and to investigate the association between caregivers' coping styles and psychological distress over time. Methods: Fifty-four caregivers were followed in a RCT of patients in the early stage of ALS. Questionnaires were administered at baseline, 4, 7, and 10 months. ⋯ Conclusion: Feelings of distress increase in ALS caregivers during the course of the disease of the patient. Emotion-oriented coping is related to psychological distress; however, emotional coping and distress might represent overlapping constructs. Focusing on one coping style in the care for ALS caregivers may be too simplistic for the complex situations they face, as it ignores the fact that people may require different coping strategies in different situations.

Primary progressive aphasia and the FTD-MND spectrum disorders: clinical, pathological, and neuroimaging correlates.
Objective: Behavioral variant frontotemporal dementia (bvFTD), is commonly considered the cognitive presentation of the frontotemporal dementia-motor neuron disease (FTD-MND) spectrum disorder. We evaluated the prevalence of primary progressive aphasia in a series of pathologically confirmed cases of FTD-MND spectrum. Methods: Pathologically confirmed cases of frontotemporal lobar degeneration-motor neuron disease (FTLD-MND) were obtained from the UCSF brain bank. ⋯ The group of svPPA-MND on imaging analysis showed selective atrophy of the temporal lobe and orbitofrontal cortex. Conclusions: Language impairment was a frequent phenotype of FTD-MND associated with focal atrophy patterns within the language networks. This data suggest patients with FTD-MND can present quite often with language phenotype of nfvPPA and svPPA, as opposed to exclusive bvFTD symptoms.
