Grey matter reduction in the occipitotemporal cortex in Spanish children with dyslexia: A voxel-based morphometry study

Structural and functional neuroimaging studies have reported brain alterations in occipitotemporal, temporoparietal, and left frontal areas in dyslexic patients. These areas have been linked to reading skill impairments, due to their involvement in word recognition and processing. However, most of the patients in these studies were speakers of languages with a deep orthography. In this study, we used voxel-based morphometry (VBM) to investigate brain differences in grey matter volume associated with a transparent language in a sample of 25 native Spanish participants (13 dyslexic and 12 non-dyslexic children). Results revealed a volume reduction in the left occipitotemporal cortex and right cerebellum in dyslexics. Significantly, the reduction in occipitotemporal areas has been previously linked to reading in transparent languages. Our results support previous studies and are consistent with the idea that reading problems in languages with a shallow orthography are related to the ventral reading network

Enzymatic acylation of di- and trisaccharides with fatty acids: choosing the appropriate enzyme, support and solvent

Enzymatic synthesis of fatty acid esters of di- and trisaccharides is limited by the fact that most biological catalysts are inactivated by the polar solvents (e.g. dimethylsulfoxide, dimethylformamide) where these carbohydrates are soluble. This article reviews the methodologies developed to overcome this limitation, namely those involving control over the reaction medium, the enzyme and the support. We have proposed the use of mixtures of miscible solvents (e.g. dimethylsulfoxide and 2-methyl-2-butanol) as a general strategy to acylate enzymatically hydrophilic substrates. We observed that decreasing the hydrophobicity of the medium (i.e. lowering the percentage of DMSO) the molar ratio sucrose diesters vs. sucrose monoesters can be substantially enhanced. The different regioselectivity exhibited by several lipases and proteases makes feasible to synthesize different positional isomers, whose properties may vary considerably. In particular, the lipase from Thermomyces lanuginosus displays a notable selectivity for only one hydroxyl group in the acylation of sucrose, maltose, leucrose and maltotriose, compared with lipase from Candida antarctica. We have examined three immobilisation methods (adsorption on polypropylene, covalent coupling to Eupergit C, and silica-granulation) for sucrose acylation catalyzed by T. lanuginosus lipase. The morphology of the support affected significantly the reaction rate and/or the selectivity of the processWe are grateful to Loreto Bajón (Instituto de Catálisis) for technical help with electron microscopy.

Oxygen Saturation Behavior by Pulse Oximetry in Female Athletes: Breaking Myths

The myths surrounding women’s participation in sport have been reflected in respiratory physiology. This study aims to demonstrate that continuous monitoring of blood oxygen saturation during a maximal exercise test in female athletes is highly correlated with the determination of the second ventilatory threshold (VT2) or anaerobic threshold (AnT). The measurements were performed using a pulse oximeter during a maximum effort test on a treadmill on a population of 27 healthy female athletes. A common behavior of the oxygen saturation evolution during the incremental exercise test characterized by a decrease in saturation before the aerobic threshold (AeT) followed by a second significant drop was observed. Decreases in peripheral oxygen saturation during physical exertion have been related to the athlete’s physical fitness condition. However, this drop should not be a limiting factor in women’s physical performance. We found statistically significant correlations between the maximum oxygen uptake and the appearance of the ventilatory thresholds (VT1 and VT2), the desaturation time, the total test time, and between the desaturation time and the VT2. We observed a relationship between the desaturation time and the VT2 appearance. Indeed, a linear regression model between the desaturation time and the VT2 appearance can predict 80% of the values in our sample. Besides, we suggest that pulse oximetry is a simple, fairly accurate, and non-invasive technique for studying the physical condition of athletes who perform physical exertion

Ocurrence of Enteroparasites with zoonotic potential in animals of the rural area of San Andres, Chimborazo, Ecuador

Objective: The aim of this research was the identification of the enteroparasites harbored by the animals of the San Andrés community, to evaluate their role as susceptible hosts and sources of infection for other animals, humans (zoonoses), as well as parasite forms spreaders to the environment in this rural area, located in the province of Chimborazo, Ecuadorian Andean region. Material and methods: The study was carried out combining 3 coproparasitological techniques: direct examination, Ritchie and Ziehl-Neelsen in 300 animal stool samples. Results: Blastocystis sp., Entamoeba spp., Giardia spp., Balantidium spp., Cryptosporidium spp., Ascaris spp., Toxocara spp., Ancylostoma spp., Strongylida, Hymenolepis nana and Echinococcus spp., were detected. Infection by protozoa (87.3%) was higher than helminths (31.0%). All cattle, sheep and guinea pigs were found parasitized, and the presence of Blastocystis sp., Entamoeba spp. and Cryptosporidium spp. by all groups of animals stands out. It is also remarkable the presence of Giardia spp. in swine (19.2%), big herbivores-livestock (11.5%), leporids (8.3%) and carnivores (5.9%); Balantidium spp. in swine (19.2%), big herbivores-livestock (5.8%) and carnivores (1.2%); Hymenolepis nana in guinea pigs (2.1%); and Toxocara spp. (15.7%), Echinococcus spp. (9.6%) and Ancylostoma spp. (6.0%) in dogs. Conclusion: Animals from San Andrés have a wide spectrum of intestinal parasitic forms in their feces, being a source of infection to other animals and humans, and a source of contamination of the environment, posing a risk factor and reinforcing the idea of the need for more effective treatments and hygienic measures to improve livestock production and cutting its transmission

Cádmio presente no sangue e a sua relação com o consumo de tabaco numa população de trabalhadores de um hospital

Exposure to cadmium is a public health problem due to the broad exposure to this toxic substance among the general population. The main sources of exposure are both tobacco consumption and tobacco smoke.The aim of this study was to determine the blood cadmium concentration in an employee population drawn from our hospital and its association with tobacco consumption.The exposure questionnaire PESA® was administered to 395 employees. Blood cadmium was measured by electrothermal atomization atomic absorption spectrometry.The median blood cadmium concentration was 0.29 μg/L. The median cadmium of current smokers (0.83 μg/L) was the highest, while that for ex-smokers (0.31 μg/L) was also higher than that for those who had never smoked. Among the smokers, an association was observed between the concentration of blood cadmium and the number of cigarettes inhaled.The group of ex-smokers showed an association with the number of cigarettes they had consumed and a negative correlation between the elapsed time between quitting smoking and the concentration of blood cadmium.In never smokers, there was a difference between the concentration of cadmium in those who were passive smokers (0.24 μg/L) and those who were not (0.20 μg/L).The concentration of cadmium in blood is related to the tobacco consumption. Further studies are needed to confirm the finding of higher concentrations of cadmium in passive smokers.La exposición de la población general al cadmio es un problema de salud pública, siendo las principales fuentes tanto el consumo de tabaco como la exposición al humo del mismo.El objetivo de este trabajo fue determinar la concentración de cadmio en sangre en una población laboral hospitalaria y su asociación con el consumo de tabaco.Se administró el cuestionario PESA® a 395 sujetos. El cadmio en sangre se midió por espectrometría de absorción atómica con atomización electrotérmica.La mediana de cadmio en sangre fue 0,29 μg/L. La mediana de cadmio de los fumadores (0,83 μg/L) fue la más elevada y la de los exfumadores (0,31 μg/L) fue a su vez más elevada que la de aquellos que nunca habían fumado (0,21 μg/L). Dentro del grupo de fumadores, se observó una asociación entre la concentración de cadmio y el número de cigarrillos inhalados.En el grupo de exfumadores se observó una asociación con el número de cigarrillos que habían consumido y una correlación negativa entre el tiempo transcurrido desde el abandono del hábito tabáquico y la concentración de cadmio en sangre.Dentro del grupo de los que nunca habían fumado, se observó una diferencia entre la concentración de cadmio de los fumadores pasivos (0,24 μg/L) y los que no lo eran (0,20 μg/L).La concentración de cadmio en sangre se relacionó con el consumo de tabaco. Son necesarios más estudios para confirmar el hallazgo de concentraciones de cadmio más elevadas en los fumadores pasivos.A exposição da população em geral ao cádmio é um problema de saúde pública, sendo as principais fontes o consumo de tabaco e a exposição ambiental ao fumo do mesmo. Este trabalho teve como objetivo determinar a concentração de cádmio no sangue numa população de trabalhadores de um hospital e a sua associação com o consumo de tabaco. Aplicou-se um questionário PESA® a 395 indivíduos. O cádmio no sangue mediu-se por espectrometria de absorção atómica com atomização eletrotérmica. A mediana de cádmio no sangue foi 0,29 μg/L. A mediana de cádmio nos fumadores (0,83 μg/L) foi a mais elevada e a dos ex-fumadores (0,31 μg/L) foi superior à dos indivíduos que nunca tinham fumado (0,21 μg/L). Dentro do grupo de fumadores, observou-se uma associação entre a concentração de cádmio e o número de cigarros fumados. No grupo de ex-fumadores observou-se uma associação com o número de cigarros que tinham consumido e uma correlação negativa entre o tempo decorrido desde o abandono do hábito tabágico e a concentração de cádmio no sangue. Dentro do grupo de pessoas que nunca tinham fumado, observou-se uma diferença entre a concentração de cádmio nos fumadores passivos (0,24 μg/L) em relação àqueles que não o eram (0,20 μg/L). A concentração de cádmio no sangue está relacionada com o consumo de tabaco. São necessários mais estudos para confirmar a existência de concentrações mais altas de cádmio no sangue de fumadores passivos

Dyslipidaemia in HIV-infected women on antiretroviral therapy. Analysis of 922 patients from the Spanish VACH cohort

Background: Information concerning lipid disturbances in HIV-infected women on antiretroviral therapy (ART) is scarce. The objective of the study is to describe the lipid profile in a large cohort of HIV-infected women on contemporary ART and analyse differences between regimes and patient's characteristics. Methods: Observational, multicentre, cross-sectional study from the Spanish VACH Cohort. 922 women on stable ART without lipid-lowering treatment were included. Results: Median age was 42 years, median CD4 lymphocyte count was 544 cells/mm3, and 85.6% presented undetectable HIV-1 viral load. Median total cholesterol (TC) was 189 mg/dL (interquartile range, IQR, 165-221), HDL cholesterol 53 mg/dL (IQR, 44-64), LDL cholesterol 108 mg/dL (IQR, 86-134), and triglycerides 116 mg/dL (IQR, 85-163). Mean accumulated time on ART was 116 months; 47.4% were on NNRTI-based regimes, 44.7% on PI, and 6.7% on only-NRTI therapy. 43.8% were also hepatitis C (HCV) coinfected. Patients on PI treatment presented higher TC/HDL ratio than those on NNRTI (p < 0.001). Significantly higher HDL values were observed in NNRTI-treated patients. HCV-coinfected patients presented lower TC/HDL ratio than the non HCV-coinfected. In multivariate analysis, factors independently associated with TC/HDL ratio were age, triglyceride levels and HCV co-infection. PI treatment presented a non-significant association with higher TC/HDL ratio. Conclusions: In HIV-infected women, the NNRTI-based ART is associated with a better lipid profile than the PI-based. Factors unrelated to ART selection may also exert an independent, significant influence on lipids; in particular, age, and triglyceride levels are associated with an increased TC/HDL ratio while HCV co-infection is associated with a reduced TC/HDL ratio

Irisin, in women and men: blood pressure, heart rate, obesity and insulin resistance

BackgroundIrisin is a myokine that increases with leisure time physical activity (LTPA) and for which a cardiovascular protective role has been postulated. Our aim was to assess this role in the general population.MethodsA cross-sectional analysis was performed in a large randomly selected population sample (n=2298 women and 1529 men). Apart from age and sex, we record anthropometrics (blood pressure, heart rate, obesity), lifestyle (LTPA, smoking, alcohol), and biochemical measurements (irisin, lipid profile, insulin resistance). Correlations and regression multivariate models were used to analyze the association of irisin levels with the studied factors.ResultsThe variables more strongly and directly associated with irisin, adjusting the studied factors separately in women and men, were HOMA-2 (p=0.043 and p=0.001, respectively) and LTPA (p&lt;0.001 and p=0.001, respectively). Also heart rate inversely (p=0.005 and p=0.002, respectively) and DBP directly (p&lt;0.005 and p=0.045, respectively) were associated to irisin in both sexes. The waist/height ratio (p&lt;0.001) was inversely associated to irisin only in women, and the alcohol drinking was directly associated (p=0.029) only in men.ConclusionWe provide new findings for irisin, such as its association with DBP and with heart rate; furthermore, in women irisin is associated to abdominal obesity, and in men is associated to the alcohol intake. We also corroborate the association of irisin with LTPA and insulin resistance. The associations detected point towards a protective role of irisin in the maintenance of cardiometabolic health

Mortality and other adverse outcomes in patients with type 2 diabetes mellitus admitted for COVID-19 in association with glucose-lowering drugs: a nationwide cohort study

Background: Limited evidence exists on the role of glucose-lowering drugs in patients with COVID-19. Our main objective was to examine the association between in-hospital death and each routine at-home glucose-lowering drug both individually and in combination with metformin in patients with type 2 diabetes mellitus admitted for COVID-19. We also evaluated their association with the composite outcome of the need for ICU admission, invasive and non-invasive mechanical ventilation, or in-hospital death as well as on the development of in-hospital complications and a long-time hospital stay. Methods: We selected all patients with type 2 diabetes mellitus in the Spanish Society of Internal Medicine’s registry of COVID-19 patients (SEMI-COVID-19 Registry). It is an ongoing, observational, multicenter, nationwide cohort of patients admitted for COVID-19 in Spain from March 1, 2020. Each glucose-lowering drug user was matched with a user of other glucose-lowering drugs in a 1:1 manner by propensity scores. In order to assess the adequacy of propensity score matching, we used the standardized mean difference found in patient characteristics after matching. There was considered to be a significant imbalance in the group if a standardized mean difference > 10% was found. To evaluate the association between treatment and study outcomes, both conditional logit and mixed effect logistic regressions were used when the sample size was ≥ 100. Results: A total of 2666 patients were found in the SEMI-COVID-19 Registry, 1297 on glucose-lowering drugs in monotherapy and 465 in combination with metformin. After propensity matching, 249 patients on metformin, 105 on dipeptidyl peptidase-4 inhibitors, 129 on insulin, 127 on metformin/dipeptidyl peptidase-4 inhibitors, 34 on metformin/sodium-glucose cotransporter 2 inhibitor, and 67 on metformin/insulin were selected. No at-home glucose-lowering drugs showed a significant association with in-hospital death; the composite outcome of the need of intensive care unit admission, mechanical ventilation, or in-hospital death; in-hospital complications; or long-time hospital stays. Conclusions: In patients with type 2 diabetes mellitus admitted for COVID-19, at-home glucose-lowering drugs showed no significant association with mortality and adverse outcomes. Given the close relationship between diabetes and COVID-19 and the limited evidence on the role of glucose-lowering drugs, prospective studies are needed
