The intestinal mycobiota and its relationship with overweight, obesity and nutritional aspects
2021
[Background]: The fungal community of the gastrointestinal tract has recently become of interest, and knowledge of its relationship with the development of obesity is scarce. The present study aimed to evaluate the cultivable fungal fraction from the microbiota and to analyze its relationship with obesity.
Dimethyl Fumarate Treatment Mediates an Anti-Inflammatory Shift in B Cell Subsets of Patients with Multiple Sclerosis
2017
Abstract The therapeutic mode of action of dimethyl fumarate (DMF), approved for treating patients with relapsing-remitting multiple sclerosis, is not fully understood. Recently, we and others demonstrated that Ab-independent functions of distinct B cell subsets are important in mediating multiple sclerosis (MS) relapsing disease activity. Our objective was to test whether and how DMF influences both the phenotype and functional responses of disease-implicated B cell subsets in patients with MS. High-quality PBMC were obtained from relapsing-remitting MS patients prior to and serially after initiation of DMF treatment. Multiparametric flow cytometry was used to monitor the phenotype and fun…
Colorectal cancer with microsatellite instability: Right-sided location and signet ring cell histology are associated with nodal metastases, and extr…
2021
Colorectal cancer (CRC) with microsatellite instability (MSI) accounts for 15-18 % of all CRCs and represents the category with the best prognosis. This study aimed at determining any possible clinical/pathological features associated with a higher risk of nodal metastasization in MSI-CRC, and at defining any possible prognostic moderators in this setting. All surgically resected CRCs of the last 20 years (mono-institutional series) with a PCR-based diagnosis of MSI, with and without nodal metastasis, have been retrieved for histological review, which was performed following WHO guidelines. Furthermore, the most important prognostic moderators have been investigated with a survival analysis…
Molecular characterization of congenital myasthenic syndromes in Spain.
2017
Congenital myasthenic syndromes (CMS) are a heterogeneous group of genetic disorders, all of which impair neuromuscular transmission. Epidemiological data and frequencies of gene mutations are scarce in the literature. Here we describe the molecular genetic and clinical findings of sixty-four genetically confirmed CMS patients from Spain. Thirty-six mutations in the CHRNE, RAPSN, COLQ, GFPT1, DOK7, CHRNG, GMPPB, CHAT, CHRNA1, and CHRNB1 genes were identified in our patients, with five of them not reported so far.. These data provide an overview on the relative frequencies of the different CMS subtypes in a large Spanish population. CHRNE mutations are the most common cause of CMS in Spain, …
Application of tRNS to improve multiple sclerosis fatigue: a pilot, single-blind, sham-controlled study
2019
We evaluated the effects of transcranial random noise stimulation (tRNS) on fatigue in 17 subjects with relapsing–remitting multiple sclerosis with low physical disability. Two different patient groups underwent real or sham stimulation for 10 days, targeting the primary motor cortex of the dominant side or contralateral to the most compromised limb. In the ‘real group’, beneficial effects were observed using the Modified Fatigue Impact Scale (p = 0.04; physical subscale: p = 0.03), the subscales ‘change in health’ (p = 0.006) and ‘role limitations due to physical problems’ (p = 0.001) of the Multiple Sclerosis Quality of Life-54, and by assessing the patient impression of perceived fatigue…
Moral Cognition and Multiple Sclerosis: A Neuropsychological Study
2017
Objectives Recent literature proved that social cognition impairments may characterize the neuropsychological profile of Multiple Sclerosis (MS) patients. However, little is still known about moral cognition in MS. In this study, we evaluated non-social, social, and moral cognitive performances in 45 relapsing-remitting MS patients. Methods Patients underwent the Brief International Cognitive Assessment for Multiple Sclerosis battery, the Cognitive Estimation and Stroop tasks, the Ekman-60 Faces test, the Reading the Mind in the Eye and Story-based Empathy task. Additionally, a task of moral dilemmas including both "instrumental" and "incidental" conditions was administered to patients. For…
Laquinimod dampens IL-1β signaling and Th17-polarizing capacity of monocytes in patients with MS
2020
ObjectiveTo assess the impact of laquinimod treatment on monocytes and to investigate the underlying immunomodulatory mechanisms in MS.MethodsIn this cross-sectional study, we performed in vivo and in vitro analyses of cluster of differentiation (CD14+) monocytes isolated from healthy donors (n = 15), untreated (n = 13), and laquinimod-treated patients with MS (n = 14). Their frequency and the expression of surface activation markers were assessed by flow cytometry and the viability by calcein staining. Cytokine concentrations in the supernatants of lipopolysaccharide (LPS)-stimulated monocytes were determined by flow cytometry. The messenger ribonucleic acid (mRNA) expression level of gene…
Treatment of painful radiculopathies with capsaicin 8% cutaneous patch.
2017
The treatment of neuropathic pain due to low-back (lumbosacral) radiculopathies, a common source of neuropathic pain, is challenging and often requires a multimodal therapeutic approach. The capsaicin 8% patch is the first topical analgesic licensed for peripheral neuropathic pain. To evaluate this treatment, a subset of patients with painful radiculopathy (lumbar and cervical, including ventral and dorsal rami) enrolled into the multicenter, non-interventional QUEPP study (QutenzaOf the 1044 study participants, 50 were diagnosed with painful radiculopathy as only peripheral neuropathic pain syndrome and were eligible for evaluation. Patients received a single treatment (visit 1) with follo…
Secondary tactile hypoesthesia: a novel type of pain-induced somatosensory plasticity in human subjects
2004
Quantitative sensory testing revealed that pain induced by intracutaneous capsaicin injection elicited secondary hyperalgesia coexisting with secondary tactile hypoesthesia. Mapping the areas of altered mechanical sensations adjacent to the capsaicin injection disclosed that the area of secondary hyperalgesia was always nested in a larger area of secondary hypoesthesia easily detected as numbness by most subjects. Psychometric functions revealed a twofold rightward shift of tactile detection (hypoesthesia), which coexisted with a more than fourfold leftward shift of pricking pain detection (hyperalgesia) in the same skin area. As a mechanism we propose a functional switch at the spinal leve…
Physical Activity Predicts Population-Level Age-Related Differences in Frontal White Matter
2018
Physical activity has positive effects on brain health and cognitive function throughout the life span. Thus far, few studies have examined the effects of physical activity on white matter microstructure and psychomotor speed within the same, population-based sample (critical if conclusions are to extend to the wider population). Here, using diffusion tensor imaging and a simple reaction time task within a relatively large population-derived sample (N = 399; 18–87 years) from the Cambridge Centre for Ageing and Neuroscience (Cam-CAN), we demonstrate that physical activity mediates the effect of age on white matter integrity, measured with fractional anisotropy. Higher self-reported daily ph…
