ABSTRACT

La insuficiencia cardiaca aguda (ICA) está asociada a una importante morbimortalidad, constituyendo la primera causa de hospitalización en mayores de 65 años en nuestro país. Las principales recomendaciones recogidas son: 1) al ingreso, se recomienda realizar una evaluación integral, considerando el tratamiento habitual y comorbilidades, ya que condicionan el pronóstico; 2) en las primeras horas de atención hospitalaria, el tratamiento descongestivo es prioritario, y se recomienda un abordaje terapéutico diurético precoz y escalonado en función de la respuesta; 3) durante la fase estable, se recomienda considerar el inicio y/o titulación del tratamiento con fármacos basados en la evidencia, es decir, sacubitrilo/valsartán o inhibidores de la enzima convertidora de angiotensina/antagonistas de los receptores de angiotensina II, betabloqueantes, antialdosterónicos e inhibidores SGLT2, y 4) en el momento del alta hospitalaria, es recomendable utilizar un listado —tipo check-list— para optimizar el manejo del paciente hospitalizado e identificar las opciones más eficientes para mantener la continuidad de cuidados tras el alta (AU)


Acute heart failure (AHF) is associated with significant morbidity and mortality and it stands as the primary cause of hospitalization for individuals over the age of 65 in Spain. This document outlines the main recommendations as follows: (1) upon admission, it is crucial to conduct a comprehensive assessment, taking into account the patient's standard treatment and comorbidities, as these factors determine the prognosis of the disease; (2) During the initial hours of hospital care, prioritizing decongestive treatment is essential. It is recommended to adopt an early staged diuretic therapeutic approach based on the patient's response; (3) In order to manage patients in the stable phase, it is advisable to consider initiating and/or adjusting evidence-based drug treatments such as sacubitril/valsartan or angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers, beta blockers, aldosterone antagonists, and SGLT2 inhibitors; (4) Upon hospital discharge, utilizing a checklist is recommended to optimize the patient's management and identify the most efficient options for ensuring continuity of care post-discharge (AU)

ABSTRACT

Objetivo El objetivo de este trabajo es evaluar el efecto de la semaglutida subcutánea sobre los biomarcadores de la enfermedad metabólica hepática (MAFLD), a saber, el índice de esteatosis hepática (HSI) y el índice de fibrosis-4 (FIB-4), a las 24semanas en pacientes ambulatorios atendidos en los servicios de Medicina Interna. Métodos En este estudio se analizaron pacientes de un registro de cohortes en curso, multicéntrico, prospectivo, pre-post y no controlado que inscribe a pacientes únicos y consecutivos con diabetes tipo2 tratados con semaglutida subcutánea. La esteatosis/fibrosis se determinó mediante HSI (<30 descartada, >36 esteatosis) y FIB-4 (<1,3 descartada, >2,67 fibrosis), respectivamente. Resultados La muestra incluyó 213 pacientes (46,9% mujeres) con una mediana de edad de 64 (±19) años. El índice de masa corporal y el peso basales medios fueron de 36,1 (±8,4) kg/m2 y 98 (±26,9) kg, respectivamente. El 99,9% presentaba valores de HSI indicativos de esteatosis, con un HSI medio de 47,9 (±8,2). Además, el 10,8% presentaba fibrosis (FIB-4 >2,67) y el 42,72% tenía valores en rangos intermedios (FIB-4 1,3-2,67). A las 24 semanas se produjo una reducción significativa del HSI (−2,36 [IC95%: 1,83-2,9], p<0,00001) y del FIB-4 (−0,075 [IC95%: 0,015-0,14], p<0,016), relacionada principalmente con descensos del peso corporal, de los niveles de triglicéridos, de la resistencia a la insulina (estimada mediante el índice triglicéridos-glucosa) y de las enzimas hepáticas. Conclusiones Estos resultados muestran que la semaglutida subcutánea tuvo un efecto beneficioso sobre la esteatosis hepática que fue más allá del control de la glucosa. Sus efectos estaban relacionados principalmente con la pérdida de peso, la disminución de los biomarcadores y la mejora de la sensibilidad a la insulina. Para muchos pacientes, la detección precoz es esencial para mejorar los resultados de la MAFLD y puede permitir seleccionar las opciones terapéuticas más eficaces (AU)


Aim This work aims to assess the effect of weekly subcutaneous semaglutide on biomarkers of metabolic-associated fatty liver disease (MAFLD), namely the hepatic steatosis index (HSI) and the fibrosis-4 (FIB-4) index, at 24weeks in outpatients attended to in internal medicine departments. Methods This study analyzed patients in an ongoing, multicenter, prospective, pre-post, uncontrolled cohort registry that enrolls unique, consecutive patients with type2 diabetes treated with weekly subcutaneous semaglutide. Steatosis/fibrosis were determined by HSI (<30 ruled out, >36 steatosis) and FIB-4 (<1.3 ruled out, >2.67 fibrosis), respectively. Results The sample included 213 patients (46.9% women) with a median age of 64 (±19) years. The median baseline body mass index and weight were 36.1 (±8.4) kg/m2 and 98 (±26.9) kg, respectively. A total of 99.9% had HSI values indicating steatosis, with a mean HSI of 47.9 (±8.2). Additionally, 10.8% had fibrosis (FIB-4 >2.67) and 42.72% had values in intermediate ranges (FIB-4 1.3-2.67). At 24weeks, there was a significant reduction in HSI (−2.36 (95%CI: 1.83-2.9), p<0.00001) and FIB-4 (−0.075 (95%CI: 0.015-0.14), p<0.016), mainly related to declines in body weight, triglyceride levels, insulin resistance (estimated by the triglyceride-glucose index), and liver enzymes. Conclusion These results show that weekly subcutaneous semaglutide had a beneficial effect on liver steatosis that went beyond glucose control. Its effects were mainly related to weight loss, a decline in biomarkers, and improvements in insulin sensitivity. For many patients, early detection is essential for improving MAFLD outcomes and may allow for selecting the most efficient treatment options (AU)

ABSTRACT

Acute heart failure (AHF) is a highly prevalent clinical entity in individuals older than 45 years in Spain. AHF is associated with significant morbidity and mortality and is the leading cause of hospitalisation for individuals older than 65 years in Spain, a quarter of whom die within 1 year of the hospitalisation. In recent years, there has been an upwards trend in hospitalisations for AHF, which increased 76.7% from 2003 to 2013. Readmissions at 30 days for AHF have also increased (from 17.6% to 22.1%), at a relative mean rate of 1.36% per year, with the consequent increase in the use of resources and the economic burden for the healthcare system. The aim of this document (developed by the Heart Failure and Atrial Fibrillation Group of the Spanish Society of Internal Medicine) is to guide specialists on the most important aspects of treatment and follow-up for patients with AHF during hospitalisation and the subsequent follow-up. The main recommendations listed in this document are as follows: 1) At admission, perform a comprehensive assessment, considering the patient's standard treatment and comorbidities, given that these determine the disease prognosis to a considerable measure. 2) During the first few hours of hospital care, decongestive treatment is a priority, and a staged diuretic therapeutic approach based on the patient's response is recommended. 3) To manage patients in the stable phase, consider starting and/or adjusting evidence-based drug treatment (e.g., sacubitril/valsartan or angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers, beta blockers and aldosterone antagonists). 4) At hospital discharge, use a checklist to optimise the patient's management and identify the most efficient options for maintaining continuity of care after discharge.

ABSTRACT

La insuficiencia cardiaca aguda (ICA) es una entidad clínica con una elevada prevalencia en la población de más de 45años en España. Está asociada a una importante morbimortalidad, constituyendo la primera causa de hospitalización en mayores de 65años en nuestro país, de los cuales una cuarta parte fallecen al año del ingreso. En los últimos años se ha observado una tendencia al alza en las hospitalizaciones por ICA, que aumentaron un 76,7% en el período de 2003 a 2013. Los reingresos a los 30días por ICA también aumentaron (del 17,6 al 22,1%) a un ritmo medio relativo del 1,36% por año, con el consiguiente incremento en el uso de recursos y en la carga económica para el sistema sanitario. Este documento, elaborado por el grupo de Insuficiencia Cardiaca y Fibrilación Auricular de la Sociedad Española de Medicina Interna, tiene como objetivo orientar al especialista en los aspectos más importantes del tratamiento y seguimiento de los pacientes con ICA durante el ingreso y el seguimiento posterior. Las principales recomendaciones recogidas son: 1)en el momento del ingreso, realizar una evaluación integral, considerando el tratamiento habitual y comorbilidades del paciente, ya que condicionan en gran medida el pronóstico de la enfermedad; 2)en las primeras horas de atención hospitalaria, el tratamiento descongestivo es prioritario y se recomienda un abordaje terapéutico diurético escalonado en función de la respuesta; 3)en el manejo de la fase estable, considerar el inicio y/o ajustar el tratamiento con fármacos basados en la evidencia, es decir, sacubitrilo/valsartán o IECA/ARAII, betabloqueantes y antialdosterónicos; 4)en el momento del alta hospitalaria, utilizar un checklist para optimizar el manejo del paciente hospitalizado e identificar las opciones más eficientes para mantener la continuidad de cuidados tras el alta (AU)

ABSTRACT

Microbial dynamics in an upgrading biogas reactor system undergoing a more than two years-period at stable operating conditions were explored. The carbon dioxide generated during biomass degradation in the first reactor of the system was converted to methane into the secondary reactor by addition of external hydrogen. Considering the overall efficiency, the long-term operation period resulted in an improved biogas upgrading performance (99% methane content). However, a remarkable accumulation of acetate was revealed, indicating the enhancement of homoacetogenic activity. For this reason, a shift in the anaerobic digestion microbiome was expected and evaluated by 16S rRNA amplicon analysis. Results demonstrated that the most abundant archaeal species identified in the first time point, Candidatus Methanoculleus thermohydrogenotrophicum, was replaced by Methanothermobacter thermautotrophicus, becoming dominant after the community adaptation. The most interesting taxonomic units were clustered by relative abundance and six main long-term adaptation trends were found, characterizing functionally related microbes (e.g. homoacetogens).

ABSTRACT

OBJECTIVES: To estimate the prevalence of obesity in patients treated by departments of Internal Medicine and to classify the patients according to the Edmonton Obesity Staging System (EOSS). MATERIAL AND METHODS: An observational, descriptive cross-sectional study included outpatients older than 18 years, with a body mass index (BMI)>30, from 38 hospitals between the 1st and 14th of February, 2016. We classified the patients according to the EOSS and analysed their clinical, laboratory and demographic variables. A value of P<.05 was considered statistically significant. RESULTS: Of the 1,262 patients treated in consultations, we recruited 298 and analysed 265. The prevalence of obesity was 23.6%, the mean age was 62.47±15.27 years, and the mean BMI was 36.1±5.3kg/m2. According to EOSS stage (0, 1, 2, 3 and 4), the prevalence was 4.9, 14.7, 62.3, 15.5 and 2.64%, respectively. Those patients with EOSS>2 were significantly older and had significantly more comorbidities. The multivariate analysis related age (OR 1.06; P<.0003), blood glucose (OR 1.04; P<.0006), total cholesterol (OR 0.98; P<.02) and uric acid (OR 1.32; P<.02) levels with an EOSS>2. An analysis of correspondence grouped, with an explanatory percentage of 78.2%, the patients according to their EOSS, comorbidity, education level, employment status and functional capacity. CONCLUSIONS: The prevalence of obesity in the patients treated by Internal Medicine departments is similar to that of the general population, although the patients are older and have a higher BMI. EOSS is useful for implementing a comprehensive approach for patients with obesity, regardless of the BMI, which can help achieve better health and quality-of-life results.

ABSTRACT

Spent sulfite liquor is a lignocellulosic waste obtained after the sulfite pulping process. It is mainly formed by sugars and lignosulfonates which are isolated from the pulp during the cooking process. The current work investigates the kinetic modeling of the sulfite process from a biorefinery point of view since monosaccharides present in the spent liquor can be used as a raw material in further biorefinery processes to produce other value-added products. Kinetic parameters of carbohydrate degradation have been determined following sugar and inhibitors from wood to spent liquor, using laboratory scale reactors and different temperatures, 130, 140 and 150 °C. Three types of reaction schemes were developed. Kinetic parameters were obtained for each one using first and n order reactions, using Aspen Custom Modeler. Results show that the best temperature to be used in the process is 130 °C, giving the maximum sugar conversion, 33.91 mol% and obtaining 13.81 mol% of decomposition products.

ABSTRACT

To analyze the effects of an intervention focused on increasing the time and intensity of Physical Education (PE), on adolescents' cognitive performance and academic achievement. A 4-month group-randomized controlled trial was conducted in 67 adolescents from South-East Spain, 2007. Three classes were randomly allocated into control group (CG), experimental group 1 (EG1) and experimental group 2 (EG2). CG received usual PE (two sessions/week), EG1 received four PE sessions/week and EG2 received four PE sessions/week of high intensity. Cognitive performance (non-verbal and verbal ability, abstract reasoning, spatial ability, verbal reasoning and numerical ability) was assessed by the Spanish Overall and Factorial Intelligence Test, and academic achievement by school grades. All the cognitive performance variables, except verbal reasoning, increased more in EG2 than in CG (all P < 0.05). Average school grades (e.g., mathematics) increased more in EG2 than in CG. Overall, EG2 improved more than EG1, without differences between EG1 and CG. Increased PE can benefit cognitive performance and academic achievement. This study contributes to the current knowledge by suggesting that the intensity of PE sessions might play a role in the positive effect of physical activity on cognition and academic success. Future studies involving larger sample sizes should confirm or contrast these preliminary findings.

ABSTRACT

Recent investigations suggest that, despite lack of lethality in validated bioassays, micropollutants in surface waters could induce sublethal toxicity in sensitive taxa, jeopardizing their biological performance and eventually leading to populations' extinction. A broader array of testing species, the miniaturization of bioassays and the development of reliable biomarkers of damage are sought in order to improve ecological relevance and cost efficiency of environmental monitoring. Our aim is to assess the different sensitivity of validated bioassays and new approaches using biomarkers as sensitive endpoints of toxicity in spores of Polystichum setiferum and Danio rerio embryos. Six water samples were collected in Tagus basin in summer and winter. Samples tested induce no acute toxicity in validated methods (algae growth inhibition and daphnia mobility inhibition). Summer water samples induced acute membrane damage (lipid peroxidation) in Danio rerio embryos and hormetic increases in fern spore mitochondrial activity. One of the samples dramatically reduced mitochondrial activity indicating severe acute sublethal phytotoxicity. All the winter samples induced significant decreases in fern spore mitochondrial activity and membrane damage increases in Danio rerio embryo. Furthermore, three samples induced lethal phytotoxicity in fern spores. We conclude that the new microbioassays show a better sensitivity to fluvial water micropollution and confirm the necessity to test critical life stages such as development and provide cost-efficient methods for environmental monitoring.

ABSTRACT

Objetivo: Realizar una revisión bibliográfica, sobre la etiología, etiopatogenia y tratamiento de las tendinopatías, así como revisar la terminología utilizada. Material y método: Se consultaron diversas fuentes electrónicas y en papel. Se utilizó Pub-med como motor de búsqueda. Resultados: Estructuralmente, la lesión se caracteriza por una alteración de los tenocitos, una desorganización del colágeno, un aumento de la sustancia fundamental y un aumento de los vasos sanguíneos. Junto a todo ello, aparece una alteración de las metaloproteasas y sus inhibidores. Estas sustancias forman parte de la homeostasis normal del tendón, pero determinados factores de riesgo pueden alterar la regulación normal de estas sustancias y podrían contribuir a iniciar y mantener el proceso de forma indefinida. También se ha descrito que el proceso de apoptosis o muerte celular programada iniciada por un citocromo y una enzima podrían estar en su origen patogénico. Conclusiones: Persiste un desconocimiento del proceso que origina y mantiene la lesión. Debido a ello, en la actualidad se han propuesto diversas opciones terapéuticas con más o menos éxito, pero ninguna con una eficacia totalmente satisfactoria. Desde el punto de vista terminológico, el término usado de tendinitis no es adecuado (AU)


Objetive: To extensively review all publicated data regarding etiology, pathogenesis and treatment of this disease and, review the terminology that was used in these processes. Material y Methods: We consulted some electronic and paper knowledge sources and Pubmed was used as a search engine. Results: Morphologically, the basic lesion is a cellular alteration of tenocytes, collagen disorganization, and an increase in matrix content and blood vessels. Moreover, metalloproteases and its inhibitors are disturbed. A programmed apoptosis of cells initiated by a cytocrom has been suggested as the origin of the disease. Conclusions: Due to ignorance of it origin, no real effective treatment has been yet achieved. Some therapeutic interventions have been proposed, with variable degree of success. From the standpoint of terminology, the term most used of tendinitis is not suitable (AU)

ABSTRACT

This study aimed to investigate the influence of prophylactic ankle taping on two balance tests (static and dynamic balance) and one jump test, in the push off and the landing phase. Fifteen active young subjects (age: 21.0 ± 4.4 years) without previous ankle injuries volunteered for the study. Each participant performed three tests in two different situations: with taping and without taping. The tests were a counter movement jump, static balance, and a dynamic posturography test. The tests and conditions were randomly performed. The path of the center of pressures was measured in the balance tests, and the vertical ground reaction forces were recorded during the push-off and landing phases of the counter movement jump. Ankle taping had no influence on balance performance or in the push off phase of the jump. However, the second peak vertical force value during the landing phase of the jump was 12% greater with ankle taping (0.66 BW, 95% CI -0.64 to 1.96). The use of prophylactic ankle taping had no influence on the balance or jump performance of healthy young subjects. In contrast, the taped ankle increased the second peak vertical force value, which could be related to a greater risk of injury produced by the accumulation of repeated impacts in sports where jumps are frequently performed. Key pointsAnkle taping has no influence on balance performance.Ankle taping does not impair performance during the push-off phase of the jump.Ankle taping could increase the risk of injury during landings by increasing peak forces.
