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.

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.

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.

ALS Cognitive Behavioral Screen (ALS-CBS): normative values for the Italian population and clinical usability.

Amyotrophic lateral sclerosis (ALS) patients often express cognitive and behavioral dysfunctions within the so-called "frontotemporal spectrum disorders." Guidelines recommend screening of such dysfunctions, albeit only ALS dedicated tools are eventually suitable, due to the profound motor limitations induced by the disease. ALS Cognitive Behavioral Screen (ALS-CBS) is such a screening tool but normative data are not available, limiting its widespread implementation. Our aim consisted in producing normative data for the Italian version of the ALS-CBS. The scale was administered to n = 458 healthy controls with different age and education. Following translation and back translation of the original version of the test, normative data and correction scores for the ALS-CBS cognitive subtest (ALS-CBSci) were generated. Furthermore, n = 100 ALS consecutive outpatients with a wide range of cognitive and motor severity underwent to the ALS-CBS, besides FAB and Weigl sorting test (WST), in order to check its usability. Completion rate was 100% for ALS-CBS and WST, and 68% for the FAB. Corrected ALS-CBS scores showed 12% detection rate of significant cognitive dysfunction with a moderate kappa with FAB and WST. For the ALS-CBS behavioral subtest (ALS-CBSbi), a caregiver was available for n = 81 ALS patients and asked to complete the subset. The detection rate for behavioral dysfunction was 55.5%, and a mild correlation between with the Caregiver Burden Inventory was present (r = - 0.26, p = 0.04). In conclusion, we offer here normative data for the ALS-CBS, a handy tool for screening frontotemporal spectrum dysfunctions in ALS patients, and confirm its usability and validity in an outpatient setting.

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.

Sport activity in Charcot-Marie-Tooth disease: A case study of a Paralympic swimmer.

This study reports the positive physical, emotional and psychosocial changes induced by sport activity in a Paralympic swimmer with Charcot-Marie-Tooth (CMT) type 4A. When we compared evaluations before initiating sport activity with those after five years of competitive activity, we found: i) increased proximal muscles strength of upper limbs; ii) augmented ability to propel wheelchair independently; iii) improved quality of life; iv) reduced trait anxiety and striking improvement of depression; v) enhanced self-esteem. Longitudinal studies in large cohorts to evaluate the positive effects of sport activity are needed to support provision of evidence-based advice to patients and families.
