Beyond lines of treatment: embracing early high-efficacy disease-modifying treatments for multiple sclerosis management.

Recent advances in multiple sclerosis (MS) management have shifted perspectives on treatment strategies, advocating for the early initiation of high-efficacy disease-modifying therapies (heDMTs). This perspective review discusses the rationale, benefits, and challenges associated with early heDMT initiation, reflecting on the obsolescence of the traditional "first-line" and "second-line" treatment classifications. The article emerges from the last update of the consensus document of the Spanish Society of Neurology on the treatment of MS.

Real-World Experience with Diroximel Fumarate in Patients with Multiple Sclerosis: A Prospective Multicenter Study.

Decisional Conflict Regarding Disease-Modifying Treatment Choices Among Patients with Mid-Stage Relapsing-Remitting Multiple Sclerosis.

Purpose: Shared decision-making is critical in multiple sclerosis (MS) due to the uncertainty of the disease trajectory over time and the large number of treatment options with differing efficacy, safety and administration characteristics. The aim of this study was to assess patients' decisional conflict regarding the choice of a disease-modifying therapy and its associated factors in patients with mid-stage relapsing-remitting multiple sclerosis (RRMS).

Methods: A multicenter, non-interventional study was conducted.

Practical tool to identify Spasticity-Plus Syndrome amongst patients with multiple sclerosis. Algorithm development based on a conjoint analysis.

Introduction: The Spasticity-Plus Syndrome (SPS) in multiple sclerosis (MS) refers to a combination of spasticity and other signs/symptoms such as spasms, cramps, bladder dysfunction, tremor, sleep disorder, pain, and fatigue. The main purpose is to develop a user-friendly tool that could help neurologists to detect SPS in MS patients as soon as possible.

Methods: A survey research based on a conjoint analysis approach was used.

Consensus statement of the Spanish Society of Neurology on the treatment of multiple sclerosis and holistic patient management in 2023.

The last consensus statement of the Spanish Society of Neurology's Demyelinating Diseases Study Group on the treatment of multiple sclerosis (MS) was issued in 2016. Although many of the positions taken remain valid, there have been significant changes in the management and treatment of MS, both due to the approval of new drugs with different action mechanisms and due to the evolution of previously fixed concepts. This has enabled new approaches to specific situations such as pregnancy and vaccination, and the inclusion of new variables in clinical decision-making, such as the early use of high-efficacy disease-modifying therapies (DMT), consideration of the patient's perspective, and the use of such novel technologies as remote monitoring.

[Transculturation and validation of a Questionnaire Factors Influencing Organ Donation].

Background: There are validated questionnaires in Spanish that evaluate the factors that influence organ donation, but they are not designed for the open population or do not delve into various aspects such as the one proposed.

Objective: Validate an instrument to evaluate the factors that influence organ donation in Mexico.

Material And Methods: Phase 1: Development of the instrument.

Feasibility of an implantable bioreactor for renal cell therapy using silicon nanopore membranes.

The definitive treatment for end-stage renal disease is kidney transplantation, which remains limited by organ availability and post-transplant complications. Alternatively, an implantable bioartificial kidney could address both problems while enhancing the quality and length of patient life. An implantable bioartificial kidney requires a bioreactor containing renal cells to replicate key native cell functions, such as water and solute reabsorption, and metabolic and endocrinologic functions.

[Rapunzel syndrome: Radiological diagnosis].

Background: Rapunzel syndrome is a rare presentation of trichobezoar, secondary to the ingestion of hair known as trichophagia. This bezoar has been found mainly in women, it invades the stomach and extends to the small intestine. Clinically, patients present weight loss and chronic obstructive symptoms at the intestinal level.

[Family planning in men and women with multiple sclerosis. Analysis of the Andalusian Registry (2018-2022)].

Introduction: The Andalusian Registry of Pregnancies in patients with multiple sclerosis is the largest Spanish registry on multiple sclerosis (MS) and family planning. For the first time, it includes information on the fertility of men with MS. The influence of the use of a disease-modifying treatment (DMT) on the health of the foetus/newborn and the impact of breastfeeding on MS are also analysed.

Cost-Analysis of Subcutaneous vs Intravenous Administration of Natalizumab Based on Patient Care Pathway in Multiple Sclerosis in Spain.

Introduction: A subcutaneous (SC) formulation of natalizumab has been recently authorised for multiple sclerosis patients. This study aimed to assess the implications of the new SC formulation, and to compare the annual treatment costs of SC versus intravenous (IV) natalizumab therapy from both the Spanish healthcare system (direct health cost) and the patient (indirect cost) perspectives.

Methods: A patient care pathway map and a cost-minimisation analysis were developed to estimate SC and IV natalizumab annual costs over a 2-year time horizon.

Superporous agarose scaffolds for encapsulation of adult human islets and human stem-cell-derived β cells for intravascular bioartificial pancreas applications.

Type 1 diabetic patients with severe hypoglycemia unawareness have benefitted from cellular therapies, such as pancreas or islet transplantation; however, donor shortage and the need for immunosuppression limits widespread clinical application. We previously developed an intravascular bioartificial pancreas (iBAP) using silicon nanopore membranes (SNM) for immunoprotection. To ensure ample nutrient delivery, the iBAP will need a cell scaffold with high hydraulic permeability to provide mechanical support and maintain islet viability and function.

Building a network of TP53 and IGHV testing reference centers across Spain: the Red53 initiative.

Among the different biomarkers predicting response in chronic lymphocytic leukemia (CLL), the most influential parameters are the mutational status of the IGHV genes and the presence of TP53 gene disruptions. Nevertheless, these important assessments are not readily available in most centers dealing with CLL patients. To provide this molecular testing across the country, the Spanish Cooperative Group on CLL (GELLC) established a network of four analytical reference centers.

Contrasting catastrophic eruptions predicted by different intrusion and collapse scenarios.

Catastrophic volcanic eruptions triggered by landslide collapses can jet upwards or blast sideways. Magma intrusion is related to both landslide-triggered eruptive scenarios (lateral or vertical), but it is not clear how such different responses are produced, nor if any precursor can be used for forecasting them. We approach this problem with physical analogue modelling enhanced with X-ray Multiple Detector Computed Tomography scanning, used to track evolution of internal intrusion, and its related faulting and surface deformation.

Modeling and validation of heat and mass transfer in individual coffee beans during the coffee roasting process using computational fluid dynamics (CFD).

Heat and mass transfer in individual coffee beans during roasting were simulated using computational fluid dynamics (CFD). Numerical equations for heat and mass transfer inside the coffee bean were solved using the finite volume technique in the commercial CFD code Fluent; the software was complemented with specific user-defined functions (UDFs). To experimentally validate the numerical model, a single coffee bean was placed in a cylindrical glass tube and roasted by a hot air flow, using the identical geometrical 3D configuration and hot air flow conditions as the ones used for numerical simulations.

Calnexin-assisted biogenesis of the neuronal glycine transporter 2 (GlyT2).

The neuronal transporter GlyT2 is a polytopic, 12-transmembrane domain, plasma membrane glycoprotein involved in the removal and recycling of synaptic glycine from inhibitory synapses. Mutations in the human GlyT2 gene (SLC6A5) that cause deficient glycine transport or defective GlyT2 trafficking are the second most common cause of hyperekplexia or startle disease. In this study we examined several aspects of GlyT2 biogenesis that involve the endoplasmic reticulum chaperone calnexin (CNX).

Subcellular localization of the neuronal glycine transporter GLYT2 in brainstem.

The neuronal glycine transporter GLYT2 belongs to the neurotransmitter:sodium:symporter (NSS) family and removes glycine from the synaptic cleft, thereby aiding the termination of the glycinergic signal and achieving the reloading of the presynaptic terminal. The task fulfilled by this transporter is fine tuned by regulating both transport activity and intracellular trafficking. Different stimuli such as neuronal activity or protein kinase C (PKC) activation can control GLYT2 surface levels although the intracellular compartments where GLYT2 resides are largely unknown.

Trafficking properties and activity regulation of the neuronal glycine transporter GLYT2 by protein kinase C.

The neuronal glycine transporter GLYT2 controls the availability of the neurotransmitter in glycinergic synapses, and the modulation of its function may influence synaptic transmission. The active transporter is located in membrane rafts and reaches the cell surface through intracellular trafficking. In the present study we prove that GLYT2 constitutively recycles between the cell interior and the plasma membrane by means of a monensin-sensitive trafficking pathway.

The neuronal glycine transporter GLYT2 associates with membrane rafts: functional modulation by lipid environment.

The neuronal glycine transporter GLYT2 is a plasma membrane protein that removes the neurotransmitter glycine from the synaptic cleft, thereby aiding the pre-synaptic terminal reloading and the termination of the glycinergic signal. Missense mutations in the gene encoding GLYT2 (SLC6A5) cause hyperekplexia in humans. The activity of GLYT2 seems to be highly regulated.
