Principales fantasías sexuales en jóvenes españoles y diferencias en función de variables sociodemográficas

Introducción: El concepto fantasía sexual define cualquier pensamiento o imagen que provoca excitación en una persona, sea una historia real, una elaboración imaginaria o un pensamiento fugaz. Son frecuentes durante la masturbación o las relaciones sexuales pero también aparecen en situaciones no sexuales. Nuestro objetivo es ana- lizar la prevalencia de las fantasías sexuales más comunes entre los jóvenes, así como estudiar posibles diferencias según distintas variables demográficas. Metodolo- gía: Se analizaron las respuestas de 192 hombres y 208 mujeres entre 18 y 26 años (m = 21,8; dt = 2,2), que contestaron de forma online al cuestionario sfq (Wilson, 1978), en su adaptación española de Sierra y cols. (2006) versionada para este estu- dio. Resultados: La edad media de inicio de fantasías sexuales es de 13,5 años (hombres: 12,7 y mujeres: 14,3; t = -6,38; p < 0,05). Se hallaron diferencias significa- tivas en el número de fantasías sexuales que presentaban ambos sexos (t = -2,062; p < 0,05), siendo la media mayor en mujeres, y se encontró una media significativa- mente superior en el grupo de jóvenes con orientación bisexual respecto al de orien- tación heterosexual (f = 9,607; p < 0,05). Entre las cinco fantasías sexuales más prevalentes en cada sexo, cuatro de ellas coincidían en hombres y mujeres. Conclu- siones: Los hombres experimentan fantasías sexuales a una edad más temprana que las mujeres. Existen diferencias significativas en el número de fantasías sexuales en función del género y la orientación sexual, pero no en su contenido.Introduction: The concept “sexual fantasy” defines any thought or image that triggers excitation in a person. It might be a real story, a drawing imaginary or a fleeting thought. They are common during masturbation or sexual intercourse but also in non-sexual situations. The aim of this study is to analyze the prevalence of the most common sexual fantasies among youth, as well as to study possible differences based on demo- graphic variables. Methodology: The responses of 192 men and 208 women aged between 18 and 26 (m = 21.8; sd = 2.2), to our particular online version of the Sierra et al. (2006) Spanish adaptation of the sfq (Wilson, 1978) were analyzed. Results: The mean age of the onset of sexual fantasies is 13.5 years (men: 12.7 and women: 14.3; t = -6.381; p < 0.05). Significant differences on the number of sexual fantasies based on sex were found (t = -2.062; p < 0.05), in which women reported a higher mean. A significant higher mean in the bisexual orientation youth group compared to the hetero- sexual orientation group was also found (f = 9.607; p < 0.05). Among the five most prevalent sexual fantasies in each sex, men and women shared four of them. Conclu- sions: Men experience sexual fantasies at an earlier age than women. There are sig- nificant differences in the amount of sexual fantasies according to sex and sexual ori- entation, but not about the subject matter

Addressing the life cycle of sewers in contrasting cities through an eco-efficiency approach

This is the peer reviewed version of the following article: [Petit‐Boix, A. , Arnal, C. , Marín, D. , Josa, A. , Gabarrell, X. and Rieradevall, J.

This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Self-ArchivingEvaluating the sustainability of the urban water cycle is not straightforward, although a variety of methods have been proposed. Given the lack of integrated data about sewers, we applied the eco-efficiency approach to two case studies located in Spain with contrasting climate, population, and urban and sewer configurations. Our goal was to determine critical variables and life cycle stages and provide results for decision making. We used life cycle assessment and life cycle costing to evaluate their environmental and economic impacts. Results showed that both cities have a similar profile, albeit their contrasting features, that is, operation and maintenance, was the main environmental issue (50% to 70% of the impacts) and pipe installation registered the greatest economic capital expenditure (70% to 75%) due to labor. The location of the wastewater treatment plant (WWTP) is an essential factor in our analysis mainly due to the topography effects (e.g., the annual pump energy was 13 times greater in Calafell). Using the eco-efficiency portfolio, we observed that sewers might be less eco-efficient than WWTPs and that we need to envision their design in the context of an integrated WWTP-sewer management to improve sewer performance. In terms of methodological approach, the bidimensional nature of eco-efficiency enables the benchmarking of product systems and might be more easily interpreted by the general public. However, there are still some constraints that should be addressed to improve communication, such as the selection of indicators discussed in the article.Peer ReviewedPostprint (author's final draft

The evolution of the ventilatory ratio is a prognostic factor in mechanically ventilated COVID-19 ARDS patients

Background: Mortality due to COVID-19 is high, especially in patients requiring mechanical ventilation. The purpose of the study is to investigate associations between mortality and variables measured during the first three days of mechanical ventilation in patients with COVID-19 intubated at ICU admission. Methods: Multicenter, observational, cohort study includes consecutive patients with COVID-19 admitted to 44 Spanish ICUs between February 25 and July 31, 2020, who required intubation at ICU admission and mechanical ventilation for more than three days. We collected demographic and clinical data prior to admission; information about clinical evolution at days 1 and 3 of mechanical ventilation; and outcomes. Results: Of the 2,095 patients with COVID-19 admitted to the ICU, 1,118 (53.3%) were intubated at day 1 and remained under mechanical ventilation at day three. From days 1 to 3, PaO2/FiO2 increased from 115.6 [80.0-171.2] to 180.0 [135.4-227.9] mmHg and the ventilatory ratio from 1.73 [1.33-2.25] to 1.96 [1.61-2.40]. In-hospital mortality was 38.7%. A higher increase between ICU admission and day 3 in the ventilatory ratio (OR 1.04 [CI 1.01-1.07], p = 0.030) and creatinine levels (OR 1.05 [CI 1.01-1.09], p = 0.005) and a lower increase in platelet counts (OR 0.96 [CI 0.93-1.00], p = 0.037) were independently associated with a higher risk of death. No association between mortality and the PaO2/FiO2 variation was observed (OR 0.99 [CI 0.95 to 1.02], p = 0.47). Conclusions: Higher ventilatory ratio and its increase at day 3 is associated with mortality in patients with COVID-19 receiving mechanical ventilation at ICU admission. No association was found in the PaO2/FiO2 variation

Study of the B-c(+) -> J/psi D-s(+) and Bc(+) -> J/psi D-s*(+) decays with the ATLAS detector

The decays B-c(+) -> J/psi D-s(+) and B-c(+) -> J/psi D-s*(+) are studied with the ATLAS detector at the LHC using a dataset corresponding to integrated luminosities of 4.9 and 20.6 fb(-1) of pp collisions collected at centre-of-mass energies root s = 7 TeV and 8 TeV, respectively. Signal candidates are identified through J/psi -> mu(+)mu(-) and D-s(()*()+) -> phi pi(+)(gamma/pi(0)) decays. With a two-dimensional likelihood fit involving the B-c(+) reconstructed invariant mass and an angle between the mu(+) and D-s(+) candidate momenta in the muon pair rest frame, the yields of B-c(+) -> J/psi D-s(+) and B-c(+) -> J/psi D-s*(+), and the transverse polarisation fraction in B-c(+) -> J/psi D-s*(+) decay are measured. The transverse polarisation fraction is determined to be Gamma +/-+/-(B-c(+) -> J/psi D-s*(+))/Gamma(B-c(+) -> J/psi D-s*(+)) = 0.38 +/- 0.23 +/- 0.07, and the derived ratio of the branching fractions of the two modes is B-Bc+ -> J/psi D-s*+/B-Bc+ -> J/psi D-s(+) = 2.8(-0.8)(+1.2) +/- 0.3, where the first error is statistical and the second is systematic. Finally, a sample of B-c(+) -> J/psi pi(+) decays is used to derive the ratios of branching fractions B-Bc+ -> J/psi D-s*+/B-Bc+ -> J/psi pi(+) = 3.8 +/- 1.1 +/- 0.4 +/- 0.2 and B-Bc+ -> J/psi D-s*+/B-Bc+ -> J/psi pi(+) = 10.4 +/- 3.1 +/- 1.5 +/- 0.6, where the third error corresponds to the uncertainty of the branching fraction of D-s(+) -> phi(K+ K-)pi(+) decay. The available theoretical predictions are generally consistent with the measurement

Progresión de escoliosis congénita por hemivértebra

Probablemente la causa más común de anomalías congénitas de la columna vertebral es la hemivértebra, definida como un fallo congénito de una vértebra para desarrollarse completamente, causado por el fracaso completo del núcleo condral de un cuerpo vertebral. Su potencial para generar una escoliosis depende del tipo, su localización, el número de vértebras afectadas y la edad.El diagnóstico va desde el hallazgo casual radiográfico, como en nuestro caso, hasta el diagnóstico por escoliosis grave. Su evolución connúa siendo impredecible y su tratamiento y pronóstico un verdadero desafío. La escoliosis ocasionada por una hemivértebra es dificil de controlar debido a que el crecimiento de la superficie superior e inferior de la hemivértebra empeora aún más el disbalance de una columna ya alterada, la curvatura puede progresar con tratamiento conservador y aún con el quirúrgico, por lo que deben seguir controles rigurosos, con especial interés en los periodos de mayor crecimiento espinal
