RESUMO

INTRODUCTION: Botulinum toxin type A (BoNT-A) is an effective and well-tolerated treatment for adult lower limb spasticity. However, data are inadequate to determine BoNT-A efficacy for active function. This study evaluated functional goal achievement (measured by goal attainment scaling [GAS]) following lower limb BoNT-A injection in clinical practice. METHODS: Phase 4, postmarketing, multicenter, prospective, observational study (NCT01444794) in adults with poststroke lower limb spasticity receiving one BoNT-A injection cycle. Assessments were at baseline (pretreatment), 1 month ±7 days (visit 1), and 3-5 months posttreatment (visit 2). Primary outcome measure was GAS; additional assessments included Modified Ashworth Scale, Demeurisse Motricity Index, 10-meter walk test, and Disability Assessment Scale. RESULTS: Of 100 enrolled patients, 94 completed the study. Most common primary treatment goals at baseline were improving mobility (57.5%) and positioning (18.1%). At visit 2, 88.3% achieved their primary goal; 87.0% (n = 47/54) for mobility, and 100.0% (n = 17/17) for positioning. In total, 79.1% of patients achieved their secondary goals. Two factors were predictive of primary goal achievement: time since stroke onset (OR 0.907; 95% CI 0.827-0.995; p = 0.038); and absence of stiff knee spasticity pattern (OR 0.228; 95% CI 0.057-0.911; p = 0.036). All functional scales showed improvements; walking speed (mean [SD]) improved by 0.06 (0.13) and 0.05 (0.20) m/s at visits 1 and 2, respectively. CONCLUSIONS: BoNT-A injection for lower limb spasticity led to high goal achievement rates in patient-centered GAS evaluation and functional and symptomatic improvements. BoNT-A may therefore deliver clinically meaningful functional improvements in real-life practice.

RESUMO

Adult hippocampal neurogenesis relies on the activation of neural stem cells in the dentate gyrus, their division, and differentiation of their progeny into mature granule neurons. The complex morphology of radial glia-like (RGL) stem cells suggests that these cells establish numerous contacts with the cellular components of the neurogenic niche that may play a crucial role in the regulation of RGL stem cell activity. However, the morphology of RGL stem cells remains poorly described. Here, we used light microscopy and electron microscopy to examine Nestin-GFP transgenic mice and provide a detailed ultrastructural reconstruction analysis of Nestin-GFP-positive RGL cells of the dentate gyrus. We show that their primary processes follow a tortuous path from the subgranular zone through the granule cell layer and ensheathe local synapses and vasculature in the inner molecular layer. They share the ensheathing of synapses and vasculature with astrocytic processes and adhere to the adjacent processes of astrocytes. This extensive interaction of processes with their local environment could allow them to be uniquely receptive to signals from local neurons, glia, and vasculature, which may regulate their fate.

RESUMO

BACKGROUND: The diagnosis of coeliac disease (CD) in adults is based on clinical, serological and histological criteria. The inappropriate performance of intestinal biopsies, non-specificity of mild histological lesions and initiation of a gluten-free diet (GFD) before biopsy may hamper the diagnosis. In these situations, determining the intraepithelial lymphogram of the duodenum by flow cytometry (IEL-FC) can be helpful. OBJECTIVES: To describe the clinical scenarios in which the IEL-FC is used and its impact on the diagnosis of CD. METHODS: All adult patients with suspected CD at three tertiary centres for whom the duodenal histology and IEL-FC were available were identified. Catassi and Fasano's diagnostic criteria and changes to a CD diagnosis after the IEL-FCs were collected. RESULTS: A total of 348 patients were included. The following indications for an IEL-FC formed part of the initial study for CD (38%): negative conventional work-up (32%), already on a GFD before duodenal biopsies (29%) and refractoriness to a GFD (2%). The IEL-FC facilitated a definitive diagnosis in 93% of patients with an uncertain diagnosis who had had a conventional work-up for CD or who were on a GFD before histology. CONCLUSIONS: The IEL-FC facilitates the confirmation or rejection of a diagnosis of CD in clinical scenarios in which a conventional work-up may be insufficient.

RESUMO

PURPOSE: Sentence Repetition Tasks (SRT) have been widely used to assess early language abilities in different languages and populations. In addition, it has been proved that performance in SRTs serve as a clinical marker to detect language difficulties. However, most of the research has been conducted in English language and with children older than 4 years of age. Despite this scarcity, [1] developed a SRT for monolingual Spanish-speaking children between 2 and 4 years of age. Initial findings showed that it is a useful tool for discriminating children with different linguistic levels. In addition, the task showed concurrent validity with a nonword repetition task. In the current study we want to explore the predictive validity of this task. METHODS: We conducted a longitudinal study including 20 monolingual Spanish-Speaking children who were tested twice, at 33 months of age and six months later. In addition to the SRT, participants completed a nonword repetition task [2] and the Spanish version of the Merrill-Palmer-R Developmental Scales [3]. RESULTS: showed strong and positive relationships between the different tests when first assessed. We also found strong and predictive relationships between the SRT at time 1 and SRT and the Merrill-Palmer-R at time 2. CONCLUSION: We conclude that the SRT developed [1] is a valid tool for examining early language abilities and its changes over time.

RESUMO

MOGHE is defined as mild malformation of cortical development with oligodendroglial hyperplasia in epilepsy. Approximately half of the patients with histopathologically confirmed MOGHE carry a brain somatic variant in the SLC35A2 gene encoding a UDP-galactose transporter. Previous research showed that D-galactose supplementation results in clinical improvement in patients with a congenital disorder of glycosylation due to germline variants in SLC35A2. We aimed to evaluate the effects of D-galactose supplementation in patients with histopathologically confirmed MOGHE, with uncontrolled seizures or cognitive impairment and epileptiform activity at the EEG after epilepsy surgery (NCT04833322). Patients were orally supplemented with D-galactose for 6 months in doses up to 1.5 g/kg/day and monitored for seizure frequency including 24-h video-EEG recording, cognition and behavioral scores, i.e., WISC, BRIEF-2, SNAP-IV, and SCQ, and quality of life measures, before and 6 months after treatment. Global response was defined by > 50% improvement of seizure frequency and/or cognition and behavior (clinical global impression of "much improved" or better). Twelve patients (aged 5-28 years) were included from three different centers. Neurosurgical tissue samples were available in all patients and revealed a brain somatic variant in SLC35A2 in six patients (non-present in the blood). After 6 months of supplementation, D-galactose was well tolerated with just two patients presenting abdominal discomfort, solved after dose spacing or reduction. There was a 50% reduction or higher of seizure frequency in 3/6 patients, with an improvement at EEG in 2/5 patients. One patient became seizure-free. An improvement of cognitive/behavioral features encompassing impulsivity (mean SNAP-IV - 3.19 [- 0.84; - 5.6]), social communication (mean SCQ - 2.08 [- 0.63; - 4.90]), and executive function (BRIEF-2 inhibit - 5.2 [- 1.23; - 9.2]) was observed. Global responder rate was 9/12 (6/6 in SLC35A2-positive). Our results suggest that supplementation with D-galactose in patients with MOGHE is safe and well tolerated and, although the efficacy data warrant larger studies, it might build a rationale for precision medicine after epilepsy surgery.

RESUMO

To estimate the prevalence of metabolic syndrome (MS) in a population receiving attention in primary care centers (PCC) we selected a random cohort of ostensibly normal subjects from the registers of 5 basic-health area (BHA) PCC. Diagnosis of MS was with the WHO, NCEP and IDF criteria. Variables recorded were: socio-demographic data, CVD risk factors including lipids, obesity, diabetes, blood pressure and smoking habit and a glucose tolerance test outcome. Of the 720 individuals selected (age 60.3 +/- 11.5 years), 431 were female, 352 hypertensive, 142 diabetic, 233 pre-diabetic, 285 obese, 209 dyslipemic and 106 smokers. CVD risk according to the Framingham and REGICOR calculation was 13.8 +/- 10% and 8.8 +/- 9.8%, respectively. Using the WHO, NCEP and IDF criteria, MS was diagnosed in 166, 210 and 252 subjects, respectively and the relative risk of CVD complications in MS subjects was 2.56. Logistic regression analysis indicated that the MS components (WHO set), the MS components (IDF set) and the female gender had an increased odds ratio for CVD of 3.48 (95CI%: 2.26-5.37), 2.28 (95%CI: 1.84-4.90) and 2.26 (95%CI: 1.48-3.47), respectively. We conclude that MS and concomitant CVD risk is high in ostensibly normal population attending primary care clinics, and this would necessarily impinge on resource allocation in primary care.
