Which are the factors influencing NIV adaptation and tolerance in ALS patients?

Amyotrophic lateral sclerosis (ALS) is a multisystemic disease compromising both the neuromuscular system and the cognitive status. Non-invasive ventilation (NIV) has been shown to improve survival and quality of life in ALS patients with respiratory failure, but scanty literature investigated which are the predictors of NIV tolerance. The aim of this study was to evaluate the impact of functional, cognitive, neurobehavioral, and respiratory status on NIV compliance and tolerance in patients with ALS. We retrospectively evaluated clinical data of ALS patients who consecutively underwent a NIV trial during hospitalization. Cognitive and neurobehavioral assessments have been performed using the Edinburgh Cognitive and Behavioral ALS Screen (ECAS), the Hospital Anxiety and Depression Scale (HADS), the Frontal Assessment Battery (FAB), the Raven's 47 Colored Progressive Matrices (PM47), and the Neurobehavioral Rating Scale Revised (NRSR). Seventy-two patients (mean age ± SD; 63.9 ± 10.6 years) were included. Patients adapted were 63/72 (87.5%). The average time of adaptation was 7.82 ± 5.27 days. The time required to reach a satisfying NIV adaptation was significantly related to the presence of sialorrhea (p = 0.02), respiratory status (Borg Dyspnoea Scale, p = 0.006, and ALS-FRS-R respiratory subscore, p = 0.03) and behavioral and cognitive impairment (NRSR-F1, p = 0.04, NRSR- F5, p = 0.04). Presence of sialorrhea and neurobehavioral impairment, and absence of respiratory symptoms are negative predictors of NIV adaptation. This study highlights the need of a multidisciplinary patient-tailored approach including cognitive-behavioral assessment and a psychological support program to optimize patient's training and compliance to NIV.

Psychosocial impact of sport activity in neuromuscular disorders.

Previous studies demonstrated the benefits of motor exercise and physical activity in neuromuscular disorders. However, very few papers assessed the effects of sport practise. The aim of this multicentre study was to assess the impact of sport activity on self-esteem and emotional regulation in a cohort of athletes with neuromuscular disorders. The 38 patients with Duchenne, Becker or other types of muscular dystrophy or spinal muscular atrophy practising sport (aged 13-49 years) and 39 age-, gender-, disability- and disease-matched patients not practising sport were enrolled. Testing procedures to assess self-esteem, anxiety and depression disorder, personality trait and quality of life (QoL) were used. Patients practising sport had a significantly higher self-esteem, lower level of depression, greater social own identity and adherence and QoL. Frequency of sport activity may represent a complementary therapy in neuromuscular disorders to improve mental and social well-being.

Intrathecal administration of Nusinersen in type 1 SMA: successful psychological program in a single Italian center.

Nusinersen is the first approved drug to treat spinal muscular atrophy (SMA). Its periodic intrathecal delivery may cause psychological burden in infants and in their parents. We report our experience during expanded access program (EAP) for type 1 SMA in a single Italian center. Because of the occurrence of stress emotional states, anxious reactions and fear before, during, and after lumbar puncture (LP), a specific psychological intervention was implemented based on regulation of emotions, anticipatory expectations, and post-event attributions. Activities included the use of fairy tales, distraction, music play through listening preferred cartoon themes in the youngest children, and contextual games and solution of fun riddle quizzes in the oldest ones. State anxiety greatly reduced in children and their parents. Treatment of psychological aspects should therefore become an integral part of health care in SMA infants and children during Nusinersen treatment.

Toward a preventive approach to prolonged grief disorder in palliative care: Insecure attachment moderates the impact of perceived support on the severity of symptoms.

OBJECTIVE: This study aimed to investigate the relationships between perceived support at the time of assistance, insecure attachment (i.e., avoidance and anxious attachment), and prolonged grief symptoms in family caregivers of palliative care patients deceased for at least one year. We also investigated the moderating role of insecure attachment in the relationship between perceived support and the intensity of prolonged grief symptoms. METHOD: An exploratory cross-sectional design was used. A sample of 157 participants completed the Prolonged Grief Scale (PG-13) and the Attachment Style Questionnaire (ASQ). RESULTS: Correlational analyses indicated that prolonged grief symptoms were positively correlated with Avoidance attachment but not with Anxious attachment. Perceived support was negatively correlated with both the Avoidance and Anxious attachment factors. Lastly, the two insecure attachment dimensions were moderately and positively correlated with each other. Results of moderation analysis showed that high Avoidance attachment moderated the effect of perceived family and social support on the intensity of prolonged grief symptoms among family caregivers of palliative home-care-assisted patients. Results also showed that the Anxious attachment factor had a significant effect on prolonged grief symptoms, even though the interaction with perceived support was not significant. CONCLUSIONS: Overall, these results underline that a high level of avoidance attachment may moderate the relationship between perceived support and the intensity of grief symptoms, thereby increasing the risk of developing a mental disorder. Interventions to prevent prolonged grief disorder among family caregivers should take these findings into account.

The 6-min walk test as a new outcome measure in Amyotrophic lateral sclerosis.

One of the issues highlighted in amyotrophic lateral sclerosis (ALS) clinical trials is the lack of appropriate outcome measures. The aim of this multicentric study was to evaluate the 6-min walk test (6MWT) as tool to monitor the natural history of a cohort of ALS patients followed up over a 6-month interval. Forty-four ambulant patients were assessed at baseline and after 1, 3 and 6 months. Eight out of forty-four lost the ability to walk before the end of the study. The 6MWT and the objective measures linked to motor function, such as 10 m walking test (10MWT) and Time-up and go (TUG), the ALSFRS-R and the ALSFRS-R items 7-9 showed a good responsiveness to change over the 6-month interval. There was a strong correlation between 6 and 10MWT, TUG, ALSFRS-R, ALSFRS-R items 7-9 and FVC% at baseline. There was no correlation with Edinburgh Cognitive and Behavioural ALS Screen (ECAS) and Modified Borg Scale (MBS). The Δ of 6MWT from T0 to T6 significantly correlated with the Δs of 10MWT and TUG. There was no correlation with the Δs of ALSFRS-R, ALSFRS-R items 7 9, ECAS, MBS and FVC%. The discordance between changes of the 6MWT and ALSFRS-R at 6 month highlights the different content validity among these instruments. The concordance among 6MWT, 10MWT and TUG indicates that the 6MWT is an objective, sensitive and robust tool to measure motor performances in a longitudinal setting. The main limitations of our study were the small sample size and the high percentage of patients (18%) lost at follow-up. Therefore, further studies on larger cohorts, and exploring the relation between 6MWT and need of ventilator support or survival could strengthen our results.
