La imagen corporal en adolescentes: expresión de los aprendizajes socioculturales adquiridos sobre el ser mujer

En este artículo se presentan los resultados de una investigación cualitativa, realizada con un grupo de quince mujeres adolescentes estudiantes del Liceo Monseñor Rubén Odio Herrera de la provincia de San José. Se recogen experiencias de estas jóvenes con respecto a la forma de vivir su femineidad en la adolescencia profundizando en cuanto a las percepciones y significados que, a través de la educación, ellas han construido alrededor del cuerpo femenino. Se reúnen algunas de las principales concepciones teóricas relativas a la imagen corporal femenina en la etapa de la adolescencia para relacionarlas con la forma en cómo las participantes conciben la maternidad, la belleza física y la necesidad de aceptación frente a otras personas. Hace referencia a la dimensión erótica del cuerpo femenino y a la necesidad de convertirlo en un instrumento para alcanzar y mantener el matrimoni

Nanodiagnostics to face SARS-CoV-2 and future pandemics : from an idea to the market and beyond

Altres ajuts: CERCA Programme/Generalitat de CatalunyaAltres ajuts: Consejo Superior de Investigaciones Científicas (CSIC) for the project "COVID19-122"The COVID-19 pandemic made clear how our society requires quickly available tools to address emerging healthcare issues. Diagnostic assays and devices are used every day to screen for COVID-19 positive patients, with the aim to decide the appropriate treatment and containment measures. In this context, we would have expected to see the use of the most recent diagnostic technologies worldwide, including the advanced ones such as nano-biosensors capable to provide faster, more sensitive, cheaper, and high-throughput results than the standard polymerase chain reaction and lateral flow assays. Here we discuss why that has not been the case and why all the exciting diagnostic strategies published on a daily basis in peer-reviewed journals are not yet successful in reaching the market and being implemented in the clinical practice

Evaluation of different bowel preparations for small bowel capsule endoscopy: a prospective, randomized, controlled study

To obtain an adequate view of the whole small intestine during capsule endoscopy (CE) a clear liquid diet and overnight fasting is recommended. However, intestinal content can hamper vision in spite of these measures. Our aim was to evaluate tolerance and degree of intestinal cleanliness during CE following three types of bowel preparation. PATIENTS AND METHODS: This was a prospective, multicenter, randomized, controlled study. Two-hundred ninety-one patients underwent one of the following preparations: 4 L of clear liquids (CL) (group A; 92 patients); 90 mL of aqueous sodium phosphate (group B; 89 patients); or 4 L of a polyethylene glycol electrolyte solution (group C; 92 patients). The degree of cleanliness of the small bowel was classified by blinded examiners according to four categories (excellent, good, fair or poor). The degree of patient satisfaction, gastric and small bowel transit times, and diagnostic yield were measured. RESULTS: The degree of cleanliness did not differ significantly between the groups (P = 0.496). Interobserver concordance was fair (k = 0.38). No significant differences were detected between the diagnostic yields of the CE (P = 0.601). Gastric transit time was 35.7 +/- 3.7 min (group A), 46.1 +/- 8.6 min (group B) and 34.6 +/- 5.0 min (group C) (P = 0.417). Small-intestinal transit time was 276.9 +/- 10.7 min (group A), 249.7 +/- 13.1 min (group B) and 245.6 +/- 11.6 min (group C) (P = 0.120). CL was the best tolerated preparation. Compliance with the bowel preparation regimen was lowest in group C (P = 0.008). CONCLUSIONS: A clear liquid diet and overnight fasting is sufficient to achieve an adequate level of cleanliness and is better tolerated by patients than other forms of preparation

Genetic Footprints of Iberian Cattle in America 500 Years after the Arrival of Columbus

Background: American Creole cattle presumably descend from animals imported from the Iberian Peninsula during the period of colonization and settlement, through different migration routes, andmay have also suffered the influence of cattle directly imported from Africa. The introduction of European cattle, which began in the 18th century, and later of Zebu from India, has threatened the survival of Creole populations, some of which have nearly disappeared or were admixed with exotic breeds. Assessment of the genetic status of Creole cattle is essential for the establishment of conservation programs of these historical resources. Methodology/Principal Findings: We sampled 27 Creole populations, 39 Iberian, 9 European and 6 Zebu breeds. We used microsatellite markers to assess the origins of Creole cattle, and to investigate the influence of different breeds on their genetic make-up. The major ancestral contributions are from breeds of southern Spain and Portugal, in agreement with the historical ports of departure of ships sailing towards the Western Hemisphere. This Iberian contribution to Creoles may also include some African influence, given the influential role that African cattle have had in the development of Iberian breeds, but the possibility of a direct influence on Creoles of African cattle imported to America can not be discarded. In addition to the Iberian influence, the admixture with other European breeds was minor. The Creoles from tropical areas, especially those from the Caribbean, show clear signs of admixture with Zebu. Conclusions/Significance: Nearly five centuries since cattle were first brought to the Americas, Creoles still show a strong and predominant signature of their Iberian ancestors. Creole breeds differ widely from each other, both in genetic structure and influences from other breeds. Efforts are needed to avoid their extinction or further genetic erosion, which would compromise centuries of selective adaptation to a wide range of environmental condition

Efecto repelente y tiempo de protección de aceites esenciales frente al estadio adulto de Aedes aegypti

The aim of this was to evaluate the repellent effect and protection time of essential oils against the adult Aedes aegypti mosquito. A completely randomized design was used with a factorial arrangement that included 10 essential oils (Minthostachys mollis, Schinus molle, Ruta graveolens, Piper aduncun, Myrica pubescens, Lippia alba, Mentha piperita, Lantana glutinosa, Cymbopogon citratus, Eucalyptus globulus and the DEET control. 10%) and four concentrations of the oils (125, 250, 500 and 1000 mg/ml). Each experimental group consisted of 50 adult female A. aegypti mosquitoes raised in the laboratory and the repellent effect and protection time were evaluated using a sedated animal bait (Rattus rattus) with applications of 0.1 ml of the oils on the legs, tail and face. The rats and mosquitoes were found in two communicating cages of 25x25x40 cm. The oils with the greatest repellent effect and protection time, respectively, were C. citratus (97.4%; 165 minutes), E. globulus (95.8%; 165 minutes), L. glutinosa (93.8%; 180 minutes) and M. piperite (93.5%; 180 minutes) in its highest concentration (1000 mg/l); with differences between oils and between concentrations (p<0.001). Likewise, DEET 10% obtained a repellency of 95.3% and a protection time of 173 minutes. It is concluded that the essential oils of C. citratus, E. globulus, L. glutinosa and M. piperita can be considered as having natural repellent potential for A. aegypti.El estudio tuvo como objetivo evaluar el efecto repelente y tiempo de protección de aceites esenciales frente al mosquito adulto de Aedes aegypti. Se trabajó con un diseño completamente al azar con arreglo factorial que incluyó 10 aceites esenciales (Minthostachys mollis, Schinus molle, Ruta graveolens, Piper aduncun, Myrica pubescens, Lippia alba, Mentha piperita, Lantana glutinosa, Cymbopogon citratus, Eucalyptus globulus y el control DEET 10%) y cuatro concentraciones de los aceites (125, 250, 500 y 1000 mg/ml). Cada grupo experimental se constituyó por 50 mosquitos hembra adultos de A. aegypti criados en laboratorio y el efecto repelente y tiempo de protección se evaluaron usando un cebo animal sedado (Rattus rattus) con aplicaciones de 0.1 ml de los aceites en patas, cola y cara. Las ratas y los mosquitos se encontraron en dos jaulas comunicadas de 25x25x40 cm. Los aceites con mayor efecto repelente y tiempo de protección, respectivamente, fueron: C. citratus (97.4%; 165 minutos), E. globulus (95.8%; 165 minutos), L. glutinosa (93.8%; 180 minutos) y M. piperita (93.5%; 180 minutos) en su concentración mayor concentración (1000 mg/l); con diferencias entre aceites y entre concentraciones (p<0.001). Asimismo, el DEET 10% obtuvo una repelencia de 95.3 % y tiempo de protección de 173 minutos. Se concluye que los aceites esenciales de C. citratus, E. globulus, L. glutinosa y M. piperita pueden considerarse con potencial repelente natural para A. aegypti

Occurrence of SARS-CoV-2 viremia is associated with genetic variants of genes related to COVID-19 pathogenesis

IntroductionSARS-CoV-2 viral load has been related to COVID-19 severity. The main aim of this study was to evaluate the relationship between SARS-CoV-2 viremia and SNPs in genes previously studied by our group as predictors of COVID-19 severity.Materials and methodsRetrospective observational study including 340 patients hospitalized for COVID-19 in the University Hospital La Princesa between March 2020 and December 2021, with at least one viremia determination. Positive viremia was considered when viral load was above the quantifiable threshold (20 copies/ml). A total of 38 SNPs were genotyped. To study their association with viremia a multivariate logistic regression was performed.ResultsThe mean age of the studied population was 64.5 years (SD 16.6), 60.9% patients were male and 79.4% white non-Hispanic. Only 126 patients (37.1%) had at least one positive viremia. After adjustment by confounders, the presence of the minor alleles of rs2071746 (HMOX1; T/T genotype OR 9.9 p < 0.0001), rs78958998 (probably associated with SERPING1 expression; A/T genotype OR 2.3, p = 0.04 and T/T genotype OR 12.9, p < 0.0001), and rs713400 (eQTL for TMPRSS2; C/T + T/T genotype OR 1.86, p = 0.10) were associated with higher risk of viremia, whereas the minor alleles of rs11052877 (CD69; A/G genotype OR 0.5, p = 0.04 and G/G genotype OR 0.3, p = 0.01), rs2660 (OAS1; A/G genotype OR 0.6, p = 0.08), rs896 (VIPR1; T/T genotype OR 0.4, p = 0.02) and rs33980500 (TRAF3IP2; C/T + T/T genotype OR 0.3, p = 0.01) were associated with lower risk of viremia.ConclusionGenetic variants in HMOX1 (rs2071746), SERPING1 (rs78958998), TMPRSS2 (rs713400), CD69 (rs11052877), TRAF3IP2 (rs33980500), OAS1 (rs2660) and VIPR1 (rs896) could explain heterogeneity in SARS-CoV-2 viremia in our population
