We performed a multicenter study in order to validate the concept that a simple CGA can identify elderly DLBCL non-fit patients in whom curative treatment is not better then palliation and to analyse potential benefits of treatment modulation after further subdividing the non-fit category by CGA criteria.One-hundred-seventy-three patients aged > 69 treated with curative or palliative intent by clinical judgment only were grouped according to CGA in fit (46%), unfit (16%) and frail (38%) categories. Two-yr OS was significantly better in fit than in non-fit patients (84% vs 47%; P <.0001). Survival in unfit and frail patients was not significantly different. Curative treatment slightly improved 2-yr OS in unfit (75% vs 44%), but not in frail patients (45% vs 39%).CGA was confirmed as very efficient in identifying elderly DLBCL patients who can benefit from a curative approach. Further efforts are needed to better tailor therapies in non-fit patients.3
The present investigation attempts to describe the correlation between sleep-time masticatory muscle activity (MMA) and psychological symptoms by the use of a four-channel electromyography (EMG) home-recording device in a group of 15 healthy volunteers completing a battery of psychometric questionnaires for the assessment of anxiety, depression and anger. The integrated EMG signal was adopted to quantify the work (μV × s) produced by each of the four muscles (bilateral masseter and temporal) during the 5-h recording span and per each 1-h increment. The duration of MMA events and the muscle work during the first hour of sleep was related to trait anxiety scores for both masseter (P = 0·007) and temporalis muscles (P = 0·022). Trait anxiety was also significantly correlated to the total amount of MMA duration (in seconds) of the temporalis muscles (r = 0·558; P = 0·031). The present investigation provides support to the hypothesis that the duration of sleep-time masticatory muscle activity, especially during the early phases of a night's sleep, may be related to anxiety trait and not to anxiety state, depression or anger. These findings may support the view that features related to the individual management of anxiety, viz. trait, are likely to be more important than acute episodes of anxiety, viz. state, in the aetiology of sleep-time masticatory muscle activity. The role of other psychological symptoms is likely to be less important.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
