Selection of disease modifying therapies in multiple sclerosis based on patient's age and disease activity: Data from a nationwide registry.

Background: Knowledge of the safety and efficacy of disease-modifying therapies (DMTs) in older patients with Multiple Sclerosis (pwMS) is limited due to their exclusion from clinical trials. Our purpose is to evaluate the choice of DMTs in pwMS older than 50 years old in a real-world setting.

Methods: Cross-sectional study of pwMS from the Argentine MS and NMOSD Registry.

Using Quinolin-4-Ones as Convenient Common Precursors for a Metal-Free Total Synthesis of Both Dubamine and Graveoline Alkaloids and Diverse Structural Analogues.

The family is one of the most studied plant families due to the large number of alkaloids isolated from them with outstanding biological properties, among them the quinoline-based alkaloids Graveoline and Dubamine . The most common methods for the synthesis of alkaloids and and their derivatives involves cycloaddition reactions or metal-catalyzed coupling processes but with some limitations in scope and functionalization of the quinoline moiety. As a continuation of our current studies on the synthesis and chemical transformation of 2-aminochalcones, we are reporting here an efficient metal-free approach for the total synthesis of alkaloids and along with their analogues with structural diversity, through a two-step sequence involving intramolecular cyclization, oxidation/aromatization, -methylation and oxidative C-C bond processes, starting from dihydroquinolin-4-ones as common precursors for the construction of the structures of both classes of alkaloids.

Minimally invasive surgery versus laparotomy in women with high risk endometrial cancer: A multi-center study performed in Argentina.

Objective: Compare the perioperative outcomes and disease-free survival between minimally invasive and open surgery in women with stage I-II high-risk endometrial cancer.

Methods: A retrospective, cohort study was performed involving twenty-four centers from Argentina. Patients with grade 3 endometrioid, serous, clear cell, undifferentiated carcinoma or carcinosarcoma who underwent hysterectomy, bilateral salpingo-oophorectomy, and staging between January 2010-2018 were included.

Aggressive multiple sclerosis in Argentina: Data from the nationwide registry RelevarEM.

Unlabelled: The objectives of the present study were to describe the frequency of aggressive multiple sclerosis (aMS) as well as to compare clinical and radiological characteristics in aMS and non-aMS patients included in RelevarEM (NCT03375177).

Methods: The eligible study population and cohort selection included adult-onset patients (≥18 years) with definite MS. AMS were defined as those reaching confirmed EDSS ≥ 6 within 5 years from symptom onset.

Absence of latitudinal gradient in oligoclonal bands prevalence in Argentina.

Background: Like MS prevalence, oligoclonal bands (OCB) frequency seems to follow a latitudinal gradient. Argentina is extensive, latitude-wise, and previous studies have not found an MS prevalence latitudinal gradient. Our aim is to describe OCB prevalence in MS, clinically isolated syndrome (CIS) and radiologically isolated syndrome (RIS) patients included in the Argentinean MS and NMOSD registry (RelevarEM) and to investigate if it follows a latitudinal gradient.

Multiple sclerosis and neuromyelitis optica spectrum disorders in Argentina: comparing baseline data from the Argentinean MS Registry (RelevarEM).

Unlabelled: The objective of this study was to describe and compare the baseline epidemiological data of multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD) patients included in RelevarEM (Clinical Trials registry number NCT03375177).

Methods: RelevarEM is a longitudinal, strictly observational MS and NMOSD registry in Argentina. Epidemiological and comorbidity data from MS and NMOSD patients were described and compared.

Synthesis, photophysical properties and theoretical studies of new bis-quinolin curcuminoid BF-complexes and their decomplexed derivatives.

This paper presents the synthesis and characterization of two series of new bis-quinolin curcuminoid BF-complexes 11 and their respective decomplexed bis-quinolin curcuminoid derivatives 12, in an attempt to understand their optical properties. The synthesized compounds showed interesting fluorescent characteristics in both solution and in solid-state. The characteristic of the electronic transitions involved in these systems were measured via Uv-vis spectroscopy and fluorescence spectroscopy.

The Argentinean multiple sclerosis registry (RelevarEM): Methodological aspects and directions.

Despite that different registries already exist in various countries in Europe and North America, no ongoing nationwide registry exists in Latin America (LATAM), a region where the disease behaves differently than in other regions. The objective of this document is to describe the methodology behind RelevarEM, the first nationwide MS registry in Argentina and LATAM. METHODS: In this article, we described the creation, implementation and data management of the nationwide MS registry in Argentina.

Effects of long-term ingestion of white tea on oxidation produced by aging and acute oxidative damage in rats.

The infusion tea extracted from the leaves of the plant Camellia sinensis can be used in the prevention of cancer, cardiovascular and neurodegenerative diseases, and aging, while adriamycin (ADR) is an anticancer drug that increases oxidative stress in cells. The present study evaluated the protective effect of the long-term consumption of white tea used at two different doses against the oxidative stress produced by aging and acute oxidation caused ADR treatment. At wearing, rats received distilled water (control), or 0.

Protective effect of white tea extract against acute oxidative injury caused by adriamycin in different tissues.

Adriamycin (ADR) is an anticancer agent that increases oxidative stress in cells. We evaluated the protective effect of the long term consumption of white tea at two different doses against this drug. For this purpose rats were given distilled water (controls), 0.

[Blood pressure in infants].

Presents a study whose information was exposed as a poster at the Congress SEUP (Spanish Society of Emergencies in Pediatrics) in Gijón 2011. Labor has emerged as a result of observed differences in criteria in the taking of blood pressure between our neonatal unit nurses.

White tea consumption slightly reduces iron absorption but not growth, food efficiency, protein utilization, or calcium, phosphorus, magnesium, and zinc absorption in rats.

We investigated the antinutritional effect of white tea extract (0, 15, and 45 mg of the tea solid extract per kilogram body weight) incorporated in the drinking water of rats for 3 and 30 days. Gender-based differences were found for all these variables, except apparent protein digestibility and the apparent absorption of calcium, phosphorus, and iron. White tea extract consumption did not significantly change body weight gain, food intake, food efficiency, protein efficiency ratio, apparent protein digestibility, nitrogen balance, or the apparent absorption of calcium, phosphorus, magnesium, and zinc.
