RESUMEN

Maize tortilla is the best-recognized food product of Mexican gastronomy. Artisanal maize tortillas (AMT) are prepared with native maize varieties and a traditional process. The aims of this study were to identify sensory attributes, texture, and color in AMT that allow them to be differentiated from commercial tortillas, and to determine the chemical and mineral composition of both types of tortillas. Six landraces related to four Mexican maize races were used. Two commercial tortillas were included as references (tortillería and supermarket). Tortillas were subjected to sensory analysis by the modified Flash technique, texture and color were measured objectively and chemical and mineral analysis of all tortillas were evaluated. Lime taste and lime smell attributes were relevant to differentiate AMT from commercial tortillas; aftertaste and fracturability attributes were highly associated to supermarket tortillas. The fracturability attribute of tortillas is consider undesirable for taco preparation. Five of the six AMT were characterized by the presence of a layer, a characteristic that is associated with traditional tortilla made by Mexican consumer. Regarding chemical composition, supermarket tortillas exhibited the highest dietary fiber content (17.09%), but showed 30% more Na than AMT, with the exception of tortillas from Purepecha native variety. Besides, supermarket tortilla had 48.9% less Ca than AMT. The sensory attributes relevant to differentiate native maize tortillas from the commercial maize tortilla references were appearance, smell, and taste, while textural and color attributes played a lesser role.

RESUMEN

La fatiga es un síndrome multidimensional, complejo y frecuente en los pacientes con daño cerebral sobrevenido, influyendo negativamente en el proceso de neurorrehabilitación. Aparece desde etapas tempranas luego de la lesión y puede permanecer en el tiempo, recuperadas o no las secuelas del daño. La fatiga depende de circuitos neuronales superiores y se define como una percepción anómala de sobreesfuerzo. Tiene una prevalencia de 29% a 77% tras el ictus, 18% a 75% tras el traumatismo craneoencefálico (TCE) y 47% a 97% tras tumores cerebrales. La fatiga se asocia a factores como sexo femenino, edad avanzada, familia disfuncional, antecedentes patológicos específicos, estado funcional (p. ej. fatiga previa a la lesión), comorbilidades, estado anímico, discapacidad secundaria y uso de ciertos fármacos. Su estudio se realiza sobre todo a partir de escalas como la Escala de severidad de fatiga (Fatigue Severity Scale). Hoy en día existen avances en herramientas de imagen para su diagnóstico como la resonancia magnética funcional. En cuanto a su tratamiento, no existe aún terapia farmacológica definitiva, sin embargo, existen resultados positivos con terapias dentro de la neurorrehabilitación convencional, terapia lumínica y el uso del neurofeedback, estimulación eléctrica y magnética transcraneal. Esta revisión tiene como objetivo ayudar al profesional dedicado a la neurorrehabilitación a reconocer factores asociados modificables, así como terapias a su alcance para disminuir sus efectos nocivos en el paciente.

Fatigue is a complex, multidimensional syndrome that is prevalent in patients with acquired brain damage and has a negative impact on the neurorehabilitation process. It presents from early stages after the injury, and may persist over time, regardless of whether sequelae have resolved. Fatigue is conditioned by upper neuronal circuits, and is defined as an abnormal perception of overexertion. Its prevalence ranges from 29% to 77% after stroke, from 18% to 75% after traumatic brain injury, and from 47% to 97% after brain tumours. Fatigue is associated with factors including female sex, advanced age, dysfunctional families, history of specific health conditions, functional status (eg, fatigue prior to injury), comorbidities, mood, secondary disability, and the use of certain drugs. Assessment of fatigue is fundamentally based on such scales as the Fatigue Severity Scale (FSS). Advances have recently been made in imaging techniques for its diagnosis, such as in functional MRI. Regarding treatment, no specific pharmacological treatment currently exists; however, positive results have been reported for some conventional neurorehabilitation therapies, such as bright light therapy, neurofeedback, electrical stimulation, and transcranial magnetic stimulation. This review aims to assist neurorehabilitation professionals to recognise modifiable factors associated with fatigue and to describe the treatments available to reduce its negative effect on patients.

RESUMEN

The ForMAX beamline at the MAX IV Laboratory provides multiscale and multimodal structural characterization of hierarchical materials in the nanometre to millimetre range by combining small- and wide-angle X-ray scattering with full-field microtomography. The modular design of the beamline is optimized for easy switching between different experimental modalities. The beamline has a special focus on the development of novel fibrous materials from forest resources, but it is also well suited for studies within, for example, food science and biomedical research.

RESUMEN

Introducción La sarcopenia en los pacientes con fractura de cadera es cada vez más habitual en la población envejecida, aumentando el riesgo de hospitalización, dependencia y mortalidad. Objetivos Valorar el tratamiento de fisioterapia más efectivo en los pacientes con sarcopenia y fractura de cadera a través de la revisión de evidencia sistemática. Métodos Se realizó una búsqueda entre febrero y mayo de 2022 en 8 bases de datos electrónicas (Pubmed, Scopus, PEDro, Web of Science, Cochrane, Google Scholar y Springer Link), con el fin de extraer ensayos clínicos publicados en los últimos 12 años en español e inglés. Resultados Se seleccionaron 3 ensayos clínicos que cumplían los criterios de inclusión. En todos ellos las intervenciones de fisioterapia incluían ejercicio aeróbico, de fuerza, de alta intensidad, de movilizaciones y combinados. La calidad metodológica se evaluó con la escala PEDro (puntuación media entre 6 y 10). Uno de los estudios no encuentra diferencias entre el tratamiento estándar y el grupo que recibe además entrenamiento progresivo de fuerza muscular. Otro constata una mejora a corto plazo en el grupo que recibe además del tratamiento convencional entrenamiento en cinta rodante con soporte del peso corporal durante el ejercicio con seguimiento a los 3 y 6 meses. El estudio que suplementa con aminoácidos esenciales es el único que constata una mejoría en los pacientes con sarcopenia. Conclusión Los pacientes con sarcopenia y fractura de cadera, pueden tener una mejor evolución si combinan ejercicios de fisioterapia con un protocolo nutricional. Son necesarias más investigaciones metodológicamente rigurosas sobre este tema para poder ampliar la evidencia. (AU)


Introduction Sarcopenia in patients with hip fracture is increasingly common in the elderly population, increasing the risk of hospitalization, dependency, and mortality. Objectives To assess the most effective physiotherapy treatment in patients with sarcopenia and hip fracture through systematic evidence review. Methods Electronic databases were searched from February to May 2022 using Pubmed, Scopus, PEDro, Web of Science, Cochrane, Google Scholar, and Springer Link in order to extract randomized clinical trials published in full text both English and Spanish for the last 12 years. Results Three clinical trials that met the inclusion criteria were selected. In all of them, the physiotherapy interventions included aerobic, strength, high intensity, mobilization, and combined exercises. Methodological quality was assessed using the PEDro scale (average score between 6 and 10). One of the studies found no differences between the standard treatment and the group that also received progressive muscle strength training. Another found a short-term improvement in the group that received, in addition to conventional treatment, treadmill training with body weight support during exercise with follow-up that was not maintained at three and six months. The study that supplements with essential amino acids is the only one that confirms an improvement in patients with sarcopenia. Conclusion Patients with sarcopenia and hip fracture may have a better evolution if they combine physiotherapy exercises with a nutritional protocol. More methodologically rigorous research on this topic is needed to expand the evidence. (AU)

RESUMEN

Animals are increasingly exposed to potential stressors related to environmental change, and multiple stressors may alter the dynamics by which animals acquire resources and invest those resources into important life-history traits. Stress may lead to the prioritization of current reproduction to maximize lifetime reproduction (i.e., terminal investment [TI]) or, in contrast, prioritize somatic investment over current reproduction to facilitate future reproductive opportunities (i.e., reproductive restraint [RR]). Tests of the TI and RR hypotheses typically use immune challenges as stressors, and have not been explicitly tested in the context of environmental change even though warming influences resource allocation patterns across taxa. Further, the multiple-stressor framework has been a useful construct to clarify the costs of complex environmental shifts to animals, but it has not been leveraged to understand such effects on investment strategy. Thus, we tested the TI and RR hypotheses by manipulating widespread features of environmental change-glyphosate-based herbicide (GBH; Roundup®) exposure and a simulated heat wave-in the variable field cricket (Gryllus lineaticeps). A simulated heat wave affected the life-history tradeoff between investment into reproduction and soma. Specifically, heat wave prioritized investment into ovary mass over non-reproductive tissue, even after accounting for food consumption, in support of the TI hypothesis. In contrast, GBH exposure did not affect any measured trait, and crickets did not discriminate between tap water and GBH solution during drinking. Therefore, some-but not all-aspects of environmental change may alter resource investment strategies in animals. We encourage continued integration of the multiple-stressor framework and life-history theory to better understand how animals respond to their rapidly changing environments.

RESUMEN

The present study evaluated the effect of the Fenton process as pretreatment for metronidazole (MNZ) removal coupled with a phytoremediation system using Scirpus lacustris as macrophyte. Initial concentrations of 0.5, 5, 10, 15, and 20 mg MNZ/L were studied in batch cultures. Results obtained in the MNZ removal by phytoremediation showed efficiencies of 93 ± 2%, 81 ± 4%, 85 ± 1%, 84 ± 2%, and 87 ± 6%, respectively. The metronidazole pretreated by the Fenton process and subsequently fed to the phytoremediation system increased the removal efficiencies up to 93 ± 3%, 99 ± 1%, 99 ± 4%, 94 ± 2%, and 94 ± 3%, respectively. Individual studies with Scirpus lacustris in touch with metronidazole displayed relative growth rates of 0.02-0.04 d-1, showing the not toxic effect of the antibiotic on the macrophyte growth. On the other hand, the BMG kinetic model best describes the removal of MNZ by phytoremediation. Finally, applying the Fenton process as a pretreatment makes the MNZ more assimilable for the phytoremediation system, converting the integration of Fenton with the phytoremediation like other attractive technology to be considered in removing emerging compounds.

RESUMEN

INTRODUCTION: Wells syndrome, also known as eosinophilic cellulitis, is a rare dermatosis with approximately 200 cases previously described in the literature. Here, we present a case of a patient with multiple sclerosis with Wells syndrome induced by dimethyl fumarate (DMF). CASE REPORT: A 41-year-old Caucasian woman was treated with DMF in July 2021. One week later, she experienced itching on her upper and lower right arm, followed by the appearance of erythematous plaques covered with vesicles. The complete blood count showed an increased eosinophil count of up to 2,000 µL. The histological images demonstrated dermal eosinophil infiltration concordant with Wells syndrome. The clinical course was benign, with complete resolution of the lesions and normalization of the eosinophil count within four weeks. Administration of corticosteroids was not necessary. CONCLUSIONS: Eosinophilia is rare in patients with multiple sclerosis treated with DMF and usually does not require dosage adjustments. Although clinical manifestations of eosinophilia in these patients are very rare, it is important for practitioners to recognize the symptoms. Many neuroleptic drugs can induce eosinophilia and systemic symptoms; therefore, physicians must be aware of the risks associated with DMF and neuroleptic drugs, particularly for quetiapine, which contains fumarate.


TITLE: Síndrome de Wells secundario a dimetilfumarato. A propósito de un caso clínico.Introducción. El síndrome de Wells, también conocido como celulitis eosinofílica, es una rara dermatosis con aproximadamente 200 casos descritos en la bibliografía. Aquí presentamos un caso clínico de un paciente con esclerosis múltiple y síndrome de Wells secundario a dimetilfumarato (DMF). Caso clínico. Mujer de 41 años que en julio de 2021 inició el tratamiento con DMF. Una semana más tarde, comenzó con prurito en las extremidades derechas, seguido por la aparición de zonas eritematosas con vesículas. El hemograma mostró elevación del recuento de los eosinófilos hasta 2.000 µL. El estudio anatomopatológico evidenció un infiltrado eosinófilo a nivel de la dermis compatible con síndrome de Wells. La evolución clínica fue favorable, con resolución de las lesiones y normalización de la eosinofilia aproximadamente en cuatro semanas. No fue necesario administrar corticoesteroides. Conclusiones. La eosinofilia es rara en los pacientes con EM tratados con DMF y generalmente no precisa ajuste de dosis. A pesar de que las manifestaciones clínicas de la eosinofilia en estos pacientes sean raras, es importante que el médico reconozca los síntomas. Numerosos neurolépticos pueden causar eosinofilia y síntomas sistémicos; por lo tanto, los facultativos deben conocer los riesgos de la asociación entre DMF y neurolépticos, en particular por la quetiapina, que contiene fumarato.

RESUMEN

Abnormal N-methyl-D-aspartate receptor (NMDAr) function has been linked to oscillopathies, psychosis, and cognitive dysfunction in schizophrenia (SCZ). Here, we investigate the role of NMDAr hypofunction in pathological oscillations and behavior. We implanted mice with tetrodes in the dorsal/intermediate hippocampus and medial prefrontal cortex (mPFC), administered the NMDAr antagonist MK-801, and recorded oscillations during spontaneous exploration in an open field and in the y-maze spatial working memory test. Our results show that NMDAr blockade disrupted the correlation between oscillations and speed of movement, crucial for internal representations of distance. In the hippocampus, MK-801 increased gamma oscillations and disrupted theta/gamma coupling during spatial working memory. In the mPFC, MK-801 increased the power of theta and gamma, generated high-frequency oscillations (HFO 155-185 Hz), and disrupted theta/gamma coupling. Moreover, the performance of mice in the spatial working memory version of the y-maze was strongly correlated with CA1-PFC theta/gamma co-modulation. Thus, theta/gamma mediated by NMDAr function might explain several of SCZ's cognitive symptoms and might be crucial to explaining hippocampal-PFC interaction.

RESUMEN

Cactaceae family is well-known for their adaptations to drought and arid environments. This family, formed by four subfamilies (Cactoideae, Opuntioideae, Pereskioideae, and Maihuenioideae) are known for being leafless stem succulent plants with numerous spines, and their commercial fruits, distinguished by their bright colors and their skin covered with bracts. Some of these species have been traditionally used in the food industry (e.g., pitaya, cactus, or prickly pear) or as pharmaceuticals to treat specific diseases due to their active properties. The processing of these fruits leads to different residues, namely pomace, skin, spines, and residues from cladodes; besides from others such as fruits, roots, flowers, mucilage, and seeds. In general, Cactaceae species produce large amounts of mucilage and fiber, although they can be also considered as a source of phenolic compounds (phenolic acids, flavonols and their glycosides), alkaloids (phenethylamines derived betalains), and triterpenoids. Therefore, considering their high content in fiber and fermentable carbohydrates, together with other target bioactive compounds, fermentation is a potential valorization strategy for certain applications such as enzymes and bioactive compounds production or aroma enhancement. This review will comprise the latest information about Cactaceae family, its potential residues, and its potential as a substrate for fermentation to obtain active molecules with application in the food industry.

RESUMEN

Nowadays, consumers are increasingly aware of the relationship between diet and health, showing a greater preference of products from natural origin. In the last decade, seaweeds have outlined as one of the natural sources with more potential to obtain bioactive carbohydrates. Numerous seaweed polysaccharides have aroused the interest of the scientific community, due to their biological activities and their high potential on biomedical, functional food and technological applications. To obtain polysaccharides from seaweeds, it is necessary to find methodologies that improve both yield and quality and that they are profitable. Nowadays, environmentally friendly extraction technologies are a viable alternative to conventional methods for obtaining these products, providing several advantages like reduced number of solvents, energy and time. On the other hand, chemical modification of their structure is a useful approach to improve their solubility and biological properties, and thus enhance the extent of their potential applications since some uses of polysaccharides are still limited. The present review aimed to compile current information about the most relevant seaweed polysaccharides, available extraction and modification methods, as well as a summary of their biological activities, to evaluate knowledge gaps and future trends for the industrial applications of these compounds.Key teaching pointsStructure and biological functions of main seaweed polysaccharides.Emerging extraction methods for sulfate polysaccharides.Chemical modification of seaweeds polysaccharides.Potential industrial applications of seaweed polysaccharides.Biological activities, knowledge gaps and future trends of seaweed polysaccharides.

RESUMEN

BACKGROUND AND OBJECTIVES: Diabetes is a chronic disease with a high impact on both health and Quality of Life Related to Health (QLRH). To evaluate the satisfaction of treatment in patients with type 2 diabetes mellitus through the Diabetes Treatment Satisfaction Questionnaire (DTSQ) and its relationship with sociodemographic variables, with antidiabetic medication and clinical-analytical variables. MATERIALS AND METHODS: This cross-sectional study was conducted in General University Hospital of San Juan de Alicante between September 2016 and December 2017. Two hundred thirty-two patients diagnosed with type 2 diabetes mellitus at least 1 year before inclusion, treated with antidiabetic medication were included. The Spanish version of the DTSQ scale was used to measure satisfaction with treatment. Factors associated with low satisfaction were analyzed by applying the Chi-square test for qualitative variables and Student-T for quantitative variables. To estimate magnitudes of association, logistic models were adjusted. RESULTS: Two hundred thirty-two patients were included in this study. 21.5% of the patients presented low satisfaction with the treatment. Patients who presented low satisfaction with treatment were associated with medications that could cause hypoglycemia (OR: 2.872 [1.195-6.903]), HbA1c levels higher than 7% (OR: 2.260 [1.005-5.083]) and drugs administered by the route oral (OR: 2.749 [1.233-6.131]). CONCLUSIONS: Patients with type 2 diabetes mellitus who had a lower score on the DTSQ questionnaire were associated with medications that produced hypoglycaemia, and with higher levels of HbA1c higher than 7%, and those who took oral medication.

RESUMEN

BACKGROUND: In those patients who do not have timely access to primary angioplasty, the pharmaco-invasive approach, that is, the use of thrombolysis as a bridging measure prior to the coronary angiography, is a safe alternative. AIM: To describe the features of patients with an acute ST-elevation myocardial infarction (STEMI) treated with a pharmaco-invasive strategy. MATERIAL AND METHODS: Descriptive observational study of 144 patients with mean age of 46 years with STEMI who received a dose of thrombolytic prior to their referral for primary angioplasty at a public hospital between 2018 and 2021. RESULTS: There were no differences the clinical presentation according to the Killip score at admission between thrombolyzed and non-thrombolyzed patients (p = ns). Fifty-three percent of non-thrombolyzed patients were admitted with an occluded vessel (TIMI 0) compared with 27% of thrombolyzed patients (p < 0.001). The thrombolyzed group required significantly less use of thromboaspiration (3.5 and 8.4% respectively; p = 0.014). Despite this, 91 and 92% of non-thrombolyzed and thrombolyzed patients achieved a post-angioplasty TIMI 3 flow. Long-term survival was 91 and 86% in thrombolyzed and non-thrombolyzed patients, respectively (p = ns). CONCLUSIONS: The pharmaco-invasive strategy is a safe alternative when compared to primary angioplasty in centers that don't have timely access to Interventional Cardiology.
