Topological Andr\'e-Quillen homology for cellular commutative SS-algebras

Topological Andr\'e-Quillen homology for commutative $S$-algebras was introduced by Basterra following work of Kriz, and has been intensively studied by several authors. In this paper we discuss it as a homology theory on CW $S$-algebras and apply it to obtain results on minimal atomic $p$-local $S$-algebras which generalise those of Baker and May for $p$-local spectra and simply connected spaces. We exhibit some new examples of minimal atomic $S$-algebras.Comment: Final revision, a version will appear in Abhandlungen aus dem Mathematischen Seminar der Universitaet Hambur

Malignant fibrous histiocytoma of the head and neck. Case report

Malignant fibrous histiocytoma (MFH) is a rare tumor included in the group of soft tissue sarcomas. Approximately 1-3% of these tumors affect the head and neck, with about 100 cases reported to date. A case affecting the retromolar trigone and involving the postero-lateral portion of the left hemi-tongue is reported. Etiological and pathological aspects are discussed. Diagnosis, treatment and prognosis of this neoplasm are reviewed.Le fibro-histiocytome malin est une tumeur rare faisant partie du groupe des sarcomes des tissus mous. Environ 1-3% de ce type de tumeur est localisé dans la région de la tête et cou, dont 100 cas ont été rapportés à ce jour. Le cas rapporté affecte le trigone rétromolaire envahissant la portion postéro-latérale de l’hémi-langue. Les aspects étiologiques et pathologiques sont discutés.

El desarrollo de la epigrafía pública indígena en el mediterráneo occidental: la base de datos Enceom

Durante los tres siglos anteriores al cambio de Era el Mediterráneo Occidental fue testigo de dos procesos paralelos: la creación de un imperio territorial impulsado por Roma y la aparición de una epigrafía expuesta en los territorios bajo su control, en unos casos recurriendo al latín y en otros a las lenguas y/o escrituras locales. El proceso fue desigual y heterogéneo: en algunos lugares la escritura había tenido previamente unos usos en el ámbito privado que se amplían a partir de esos momentos a contextos públicos. En otros puntos parece que escritura y epigrafía son introducidos al mismo tiempo. Hay diferencias también cuantitativas, ya que el fenómeno no tuvo la misma intensidad en todos los territorios. Pero lo que es común a toda el área es el importante crecimiento de la epigrafía expuesta... The aim of this article is to present the preliminary results of the ENCEOM database. Created as one of the main objectives of the Spanish research project "El nacimiento de las culturas epigraficas del Mediterraneo Occidental", the database looks for the compilation of public displayed inscriptions in indigenous languages and writings and its relationship with the Romanization process. The description of the database and the inclusion criteria used throughout this work will follow a brief introduction covering the development of the different epigraphic cultures. Then, the specific results for each one of the epigraphic spaces included until now in the database (Paleohispanic, Gaulish and Osco-Umbrian) will be presented. The article finishes with a general comparative which shows the potential of this new epigraphic cataloguing too

Ultra-processed foods and type-2 diabetes risk in the sun project: A prospective cohort study

The association between ultra-processed foods (UPF) consumption and the risk of type 2 diabetes (T2D) has not been much explored. We aimed to evaluate the association between consumption of UPF and the incidence of T2D

Inverse-probability weighting and multiple imputation for evaluating selection bias in the estimation of childhood obesity prevalence using data from electronic health records

Background and objectives: Height and weight data from electronic health records are increasingly being used to estimate the prevalence of childhood obesity. Here, we aim to assess the selection bias due to missing weight and height data from electronic health records in children older than five. Methods: Cohort study of 10,811 children born in Navarra (Spain) between 2002 and 2003, who were still living in this region by December 2016. We examined the differences between measured and non-measured children older than 5 years considering weight-associated variables (sex, rural or urban residence, family income and weight status at 2–5 yrs). These variables were used to calculate stabilized weights for inverse-probability weighting and to conduct multiple imputation for the missing data. We calculated complete data prevalence and adjusted prevalence considering the missing data using inverse-probability weighting and multiple imputation for ages 6 to 14 and group ages 6 to 9 and 10 to 14. Results: For 6–9 years, complete data, inverse-probability weighting and multiple imputation obesity age-adjusted prevalence were 13.18% (95% CI: 12.54–13.85), 13.22% (95% CI: 12.57–13.89) and 13.02% (95% CI: 12.38–13.66) and for 10–14 years 8.61% (95% CI: 8.06–9.18), 8.62% (95% CI: 8.06–9.20) and 8.24% (95% CI: 7.70–8.78), respectively. Conclusions: Ages at which well-child visits are scheduled and for the 6 to 9 and 10 to 14 age groups, weight status estimations are similar using complete data, multiple imputation and inverse-probability weighting. Readily available electronic health record data may be a tool to monitor the weight status in children

Loot box purchases and their relationship with internet gaming disorder and online gambling disorder in adolescents: a prospective study

In recent years, the video game industry has introduced Loot Box (LB), a new type of microtransaction in which a gamer uses real currency to purchase a random virtual item within a video game. Recently, LBs became more widespread and there is evidence suggesting their similarity to online gambling. Although some studies have investigated the association between LBs with disordered gaming and disordered gambling, very few have done so with clinical indicators of these problems. Furthermore, to the best of our knowledge no longitudinal evidence of such relationships currently exists in the literature. Therefore, the present study aimed to 1) ascertain the stability of LB purchasing in minors and 2) investigate the associations between LB purchasing with gambling online and online gambling disorder within six months. A prospective cohort study was conducted at two time points six months apart. In total, 2.213 Spanish adolescents (1.067 [48.9%] boys) aged between 11 and 17 years participated in both waves. The purchase of LBs was prevalent and stable in the sample across the six months. While a positive relationship was found between purchasing LBs and online gambling six months later, the relationships between purchasing LBs and the presentation of online gambling disorder and gaming disorder require further study

Virtual meeting, real and sound science: report of the 17 th Meeting of the Spanish Society for Developmental Biology (SEBD-2020)

The Spanish Society for Developmental Biology (SEBD) organized its 17th meeting in November 2020 (herein referred to as SEBD2020).This meeting, originally programmed to take place in the city of Bilbao, was forced onto an online format due to the SARS-CoV2, COVID-19 pandemic. Although, we missed the live personal interactions and missed out on the Bilbao social scene, we were able to meet online to pres- ent our work and discuss our latest results. An overview of the activities that took place around the meeting, the different scientific sessions and the speakers involved are presented here. The pros and cons of virtual meetings are discussed

Fast food consumption and gestational diabetes incidence in the SUN project

Background: Gestational diabetes prevalence is increasing, mostly because obesity among women of reproductive age is continuously escalating. We aimed to investigate the incidence of gestational diabetes according to the consumption of fast food in a cohort of university graduates. Methods: The prospective dynamic ‘‘Seguimiento Universidad de Navarra’’ (SUN) cohort included data of 3,048 women initially free of diabetes or previous gestational diabetes who reported at least one pregnancy between December 1999 and March 2011. Fast food consumption was assessed through a validated 136-item semi-quantitative food frequency questionnaire. Fast food was defined as the consumption of hamburgers, sausages, and pizza. Three categories of fast food were established: low (0–3 servings/month), intermediate (.3 servings/month and #2 servings/week) and high (.2 servings/week). Non-conditional logistic regression models were used to adjust for potential confounders. Results: We identified 159 incident cases of gestational diabetes during follow-up. After adjusting for age, baseline body mass index, total energy intake, smoking, physical activity, family history of diabetes, cardiovascular disease/hypertension at baseline, parity, adherence to Mediterranean dietary pattern, alcohol intake, fiber intake, and sugar-sweetened soft drinks consumption, fast food consumption was significantly associated with a higher risk of incident gestational diabetes, with multivariate adjusted OR of 1.31 (95% conficence interval [CI]:0.81–2.13) and 1.86 (95% CI: 1.13–3.06) for the intermediate and high categories, respectively, versus the lowest category of baseline fast food consumption (p for linear trend: 0.007). Conclusion: Our results suggest that pre-pregnancy higher consumption of fast food is an independent risk factor for gestational diabetes

Feasibility of large-scale population testing for SARS-CoV-2 detection by self-testing at home

The simplicity and low cost of rapid point-of-care tests greatly facilitate large-scale population testing, which can contribute to controlling the spread of the COVID-19 virus. We evaluated the applicability of a self-testing strategy for SARS-CoV2 in a population-based, cross-sectional study in Cantabria, Spain, between April and May 2020. For the self-testing strategy, participants received the necessary material for the self-collection of blood and performance of a rapid antibody test using lateral flow immunoassay at home without the supervision of healthcare personnel. A total of 1,022 participants were enrolled. Most participants correctly performed the COVID-19 self-test the first time (91.3% [95% CI 89.4-92.9]). Only a minority of the participants (0.7%) needed the help of healthcare personnel, while 6.9% required a second kit delivery, for a total valid test result in 96.9% of the participants. Incorrect use of the self-test was not associated with the educational level, age over 65, or housing area. Prevalence of IgG antibodies against SARS-CoV2 for subjects with a valid rapid test result was 3.1% (95% CI 2.2-4.4), similar to the seroprevalence result obtained using a conventional approach carried out by healthcare professionals. In conclusion, COVID-19 self-testing should be considered as a screening tool.Acknowledgements: We would like to acknowledge the participation of all the individuals in this study.
