Spanish Adaptation of the Dimensional Apathy Scale (DAS) in Amyotrophic Lateral Sclerosis.

Aim: To adapt, translate, and utilize the Dimensional Apathy Scale (DAS) in Amyotrophic Lateral Sclerosis (ALS) to the Spanish population. Method: We recruited 104 ALS patients (67 of their caregivers) and 49 controls. Participants completed the Spanish-translated DAS, Geriatric Depression Scale- Short form. Patients were also administered the ALS Functional Rating Scale-Revised (ALSFRS-R). Caregivers additionally completed the informant/caregiver-rated Spanish-translated DAS. The DAS was translated to Spanish using a back-translation method. Test-retest and internal consistency reliability were examined. Divergent validity was assessed by comparing the DAS with the depression scale (GDS-15). Principal Component Analysis (PCA) was applied to explore the substructure of the Spanish DAS. Results: The internal consistency reliability of self-rated Spanish DAS was 0.72 and of the informant/caregiver-rated Spanish DAS was 0.84. Correlations between self-rated DAS subscales and GDS-15 were not statistically significant, with a good test-retest reliability. PCA analysis showed a similar substructure to the original DAS. ALS patients had significantly higher Initiation apathy than controls. Additionally, ALS patient informant/caregiver-rated DAS Emotional apathy was significantly higher than the self-rated, with no significant differences observed in the Executive and Initiation subscales. No association was found between DAS and functional impairment using the ALS Functional Rating Scale (ALSFRS-R). Conclusion: The Spanish translation of the DAS is valid and reliable for use in assessing multidimensional apathy in the Spanish population. Availability of the Spanish DAS will allow for future research to explore different apathy subtypes and their impact in ALS and other conditions.

Masitinib as an add-on therapy to riluzole in patients with amyotrophic lateral sclerosis: a randomized clinical trial.

Objective: To assess masitinib in the treatment of ALS. Methods: Double-blind study, randomly assigning 394 patients (1:1:1) to receive riluzole (100 mg/d) plus placebo or masitinib at 4.5 or 3.0 mg/kg/d. Following a blinded transition from phase 2 to phase 2/3, a prospectively defined two-tiered design was implemented based on ALSFRS-R progression rate from disease-onset to baseline (ΔFS). This approach selects a more homogeneous primary efficacy population ("Normal Progressors", ΔFS < 1.1 points/month) while concurrently permitting secondary assessment of the broader population. Primary endpoint was decline in ALSFRS-R at week-48 (ΔALSFRS-R), with the high-dose "Normal Progressor" cohort being the prospectively declared primary efficacy population. Missing data were imputed via last observation carried forward (LOCF) methodology with sensitivity analyses performed to test robustness. Results: For the primary efficacy population, masitinib (n = 99) showed significant benefit over placebo (n = 102) with a ΔALSFRS-R between-group difference (ΔLSM) of 3.4 (95% CI 0.65-6.13; p = 0.016), corresponding to a 27% slowing in rate of functional decline (LOCF methodology). Sensitivity analyses were all convergent, including the conservative multiple imputation technique of FCS-REGPMM with a ΔLSM of 3.4 (95% CI 0.53-6.33; p = 0.020). Secondary endpoints (ALSAQ-40, FVC, and time-to-event analysis) were also significant. Conversely, no significant treatment-effect according to ΔALSFRS-R was seen for the broader "Normal and Fast Progressor" masitinib 4.5 mg/kg/d cohort, or either of the low-dose (masitinib 3.0 mg/kg/d) cohorts. Rates of treatment-emergent adverse events (AEs) (regardless of causality or post-onset ΔFS) were 88% with masitinib 4.5 mg/kg/d, 85% with 3.0 mg/kg/d, and 79% with placebo. Likewise, rates of serious AE were 31, 23, and 18%, respectively. No distinct event contributed to the higher rate observed for masitinib and no deaths were related to masitinib. Conclusions: Results show that masitinib at 4.5 mg/kg/d can benefit patients with ALS. A confirmatory phase 3 study will be initiated to substantiate these data.

Spanish adaptation of the edinburgh cognitive and behavioral amyotrophic lateral sclerosis screen (ECAS).

OBJECTIVE: Adaptation of the ECAS to the Spanish population. METHODS: The ECAS test was adapted and implemented in a random sample of 102 ALS patients. A test-retest reliability of the instrument and internal consistency assessment were carried out. Its convergent validity was determined by comparing the ECAS screen with the ALS Cognitive Behavioural Screen (ALS-CBS), another standard tool. RESULTS: The Spanish adaptation of the ECAS scale preserves the statistical characteristics of the original version. Its analysis revealed a high internal consistency, similar to that of the original version. A significant correlation was found between the ECAS scale and the ALS-CBS, with the highest degree of correlation values shown at the Executive and Lack of empathy domains scales. Additionally, significant differences were observed between the scores obtained in ALS patients and healthy individuals. Furthermore, the analysis of the screen discrimination ability resulted acceptable. CONCLUSION: The results of this study prove that the Spanish adaptation of the ECAS scale preserves the internal consistency and construct validity of its original version.

Zigomicosis cutanea en un paciente de 10 años: primer caso pediátrico en Venezuela: revisión de la literatura / Cutaneous zigomycosis in a 10 year-old patient: first pediatric case in Venezuela: revision of the literature

La zinomicosis es una infección aguda causada por los hongos de la clase Zigomicetos, de la cual no existen casos publicados anteriormente en el área pediátrica en nuestro país. Estos hongos producen una angioinvasión que puede manifestarse de varias formas, siendo la forma mas frecuente la rino-órbito- cerebral. Se describe el caso de un escolar masculino de 10 años que representa politraumatismo con herida muy contaminada en muslo izquierdo. Recibe antibióticos, curas quirúrgicas y dexametasona. En el curso de 13 días presentó una fascitis necrotizante con una zona aterciopelada blanca de la cual se toma muestra, diagnosticándose hongos del tipo Zigomicetos, especie Saksenaea vasiformis. Se desatircula el miembro inferior izquierdo, se le coloca Anfotericina B liposomal y Caspofungina. El paciente falleció luego de 13 días a pesar del tratamiento. La Zigomicosis cutánea severa es una patología de alta mortalidad cuyo pronóstico dependerá de un diagnóstico precoz y un manejo médico y quirúrgico agresivo. El Posaconazol ofrece nuevas perspectivas en el tratamiento de esta enfermedad.

Zygomycosis is an acute micotic infection caused by the Zygomycetes class that has not been previously described in the pediatric area in our country. These fungi produce an angioinvasion with several clinical manifestations, of which the most frequent isthe rhino-orbito-cerebral form. This is a 10 year-old male who presents with multiple injuries and a very contaminated wound in the left thigh. The child receives antibiotics, surgical cleaning, dexametaxone and presents, during the course of 13 days, a necrotizing fasciitis with a velvety white zone from where Zygomycete, specie Saksenaea vasiformis was isolated. The left thigh and leg had to bedis articulated and liposomal Amphotericin B plus Caspofungin was prescribed. In spite of the treatment the patient died 13 days later. Cutaneous Zygomycosis is a severe pathology of high mortality which prognosis will depend on an early diagnosis and aggressive medical and surgical treatment. Posaconazole offers a new perspective in the treatment of this disease.
