A serial cross-sectional study with data from 11 Spanish universities was carried out. In total, 10,096 first-year university students (73.2% female, mean age = 19.0 ± 1.5 years) completed an online self-administered questionnaire between 2012 and 2022. For some analyses, questionnaires were categorized by the year in which the survey was filled out as Before COVID-19, Lockdown, and New Normal. In total, 72.9% of participants were within the normal weight range, and 17.7% of men and 11.8% of women were overweight (p < 0.001). The students who did not meet the WHO criteria of physical activity, spent more than 7 h per day sitting, and skipped breakfast had a higher prevalence of obesity (p < 0.05). According to the period of study, the prevalence of overweight/obesity Before COVID-19 was 16.1% (95% CI: 15.4–16.9%), while in Lockdown the prevalence was significantly higher (20.2, 95% CI: 17.1–23.8) and in New Normal it was 18.9% (CI: 15.7–22.5). Moreover, the study suggests that during the Lockdown period, there was a reduction in the practice of physical activity and an increase in the prevalence of a healthy diet. For all these, it is necessary to propose public health interventions that improve the lifestyles of university students.Ministerio de Sanidad, Consumo y Bienestar Social 030, 034, 145 MISANInstituto de Salud Carlos III PI16/01947 ISCIIIEuropean Social Fund EDU/842/2022 ESFConsejería de Educación, Junta de Castilla y Leó

Association of occupational heat exposure and colorectal cancer in the MCC-Spain study

Objective Heat exposure and heat stress/strain is a concern for many workers. There is increasing interest in potential chronic health effects of occupational heat exposure, including cancer risk. We examined potential associations of occupational heat exposure and colorectal cancer (CRC) risk in a large Spanish multi-case- control study.Methods We analyzed data on 1198 histologically confirmed CRC cases and 2690 frequency-matched controls. The Spanish job-exposure matrix, MatEmEsp, was used to assign heat exposure estimates to the lifetime occupa-tions of participants. Three exposure indices were assessed: ever versus never exposed, cumulative exposure and duration (years). We estimated odds ratios (OR) and 95% confidence intervals (CI) using unconditional logistic regression adjusting for potential confounders.Results Overall, there was no association of ever, compared with never, occupational heat exposure and CRC (OR 1.09, 95% CI 0.92-1.29). There were also no associations observed according to categories of cumulative exposure or duration, and there was no evidence for a trend. There was no clear association of ever occupational heat exposure and CRC in analysis conducted among either men or women when analyzed separately. Positive associations were observed among women in the highest categories of cumulative exposure (OR 1.81, 95% CI 1.09-3.03) and duration (OR 2.89, 95% CI 1.50-5.59) as well as some evidence for a trend (P<0.05).Conclusion Overall, this study provides no clear evidence for an association between occupational heat exposure and CRC

Sleep duration and napping in relation to colorectal and gastric cancer in the MCC-Spain study

Sleep duration is a novel and potentially modifiable risk factor for cancer. We evaluated the association of self-reported sleep duration and daytime napping with odds of colorectal and gastric cancer. We included 2008 incident colorectal cancer cases, 542 gastric cancer cases and 3622 frequency-matched population controls, recruited in the MCC-Spain case-control study (2008-2013). Sleep information, socio-demographic and lifestyle characteristics were obtained through personal interviews. Multivariable adjusted logistic regression models were used to estimate odds ratios (OR) with 95% confidence intervals (CI) for cancer, across categories of sleep duration (? 5, 6, 7, 8, ? 9 hours/day), daytime napping frequency (naps/week) and duration (minutes/nap). Compared to 7 hours of sleep, long sleep was associated with increased odds of colorectal (OR?9 hours: 1.59; 95%CI 1.30-1.94) and gastric cancer (OR?9 hours: 1.95; 1.37-2.76); short sleep was associated with increased odds of gastric cancer (OR?5 hours: 1.32; 0.93-1.88). Frequent and long daytime naps increased the odds of colorectal (OR6-7 naps/week, ?30 min: 1.32; 1.14-1.54) and gastric cancer (OR6-7 naps/week, ?30 min: 1.56; 1.21-2.02). Effects of short sleep and frequent long naps were stronger among participants with night shift-work history. Sleep and circadian disruption may jointly play a role in the etiology of colorectal and gastric cancer.Funding: The study was funded by the “Accion Transversal del Cancer”, approved on the Spanish Ministry Council on 11 October 2007, by the Instituto de Salud Carlos III-FEDER (PI08/1770, PI08/0533, PI08/1359, PI09/00773-Cantabria, PI09/01286-León, PI09/01903-Valencia, PI09/02078-Huelva, PI09/01662-Granada, PI11/01403, PI11/01889-FEDER, PI11/00226, PI11/01810, PI11/02213, PI12/00488, PI12/00265, PI12/01270, PI12/00715, PI12/00150), by the Fundación Marqués de Valdecilla (API 10/09), by the ICGC International Cancer Genome Consortium CLL (The ICGC CLL-Genome Project is funded by Spanish Ministerio de Economía y Competitividad (MINECO) through the Instituto de Salud Carlos III (ISCIII) and Red Temática de Investigación del Cáncer (RTICC) del ISCIII (RD12/0036/0036)), by the Junta de Castilla y León (LE22A10-2), by the Consejería de Salud of the Junta de Andalucía (2009-S0143), by the Conselleria de Sanitat of the Generalitat Valenciana (AP_061/10), by the Recercaixa (2010ACUP 00310), by the European Commission grants FOOD-CT-2006-036224-HIWATE, by the Spanish Association Against Cancer (AECC) Scientific Foundation, by the Catalan Government DURSI grant 2009SGR1489.

Uso de tecnología solar en actividades agropecuarias de la Región Huetar Norte de Costa Rica (Parte I y II)

Instituto Tecnológico de Costa Rica, 2021Este manual se pretende mostrar los resultados de la aplicación de esta energía en sistemas de producción agropecuaria en la Región Huetar Norte de Costa Rica. Para ello se ha montado varios sistemas térmicos y uno fotovoltaico y se ha determinado su volumen de producción a través de un sistema computarizado de registro de datos. La primera parte del manual “Uso de tecnología solar en actividades agropecuarias de la Región Huetar Norte de Costa Rica. Manual Técnico” fue el resultado de los primeros proyectos de investigación y extensión desarrollados entre 2014 y 2017 por Grupo de Investigación en Sistemas Térmicos Solares para la Agricultura del Programa de Doctorado en Ciencias Naturales para el Desarrollo del Programa de Doctorado en Ciencias Naturales para el Desarrollo (Campus Tecnológico Local San Carlos, Instituto Tecnológico de Costa Rica), cuyos integrantes comenzaron a trabajar en la aplicación de la tecnología térmica solar en otras actividades agrícolas (secado, escaldado, entre otros) a partir de 2017. Esta segunda parte está compuesta por un compendio de artículos publicados en diferentes medios científicos, técnicos, divulgativos y memorias de eventos científicos y, también incluye algunos otros resultados producto del registro, la evaluación de los datos del funcionamiento de estos equipos y los planos de cada uno de los sistemas (Cuadro 1). El proyecto que dio inicio a la aplicación de sistemas solares en unidades de producción agrícola, especialmente en ganadería, se denominó “Implementación de tecnologías solares en actividades económicas agropecuarias en la zona Huetar Norte de Costa Rica. Programa local piloto”, el cual estuvo inscrito en el Programa de Regionalización Universitaria (PUR-CONARE) y que inició en 2014 en el Campus Tecnológico Local San Carlos (ITCR) y contó con un financiamiento de 10 millones de colones aportados por el ITCR. Ese proyecto, así como la experiencia generada por los investigadores, abrió la puerta para la ejecución de otros proyectos relacionados (cuadro 2) que lograron atraer más de 200 millones de colones de fondos externos (MAG- FITTACORI, INDER, Fundación CRUSA) para la utilización de energía solar en las actividades de pequeños y medianos productores agropecuarios y agroindustriales, comunidades, así como a cooperativas y asociaciones de productores legalmente constituidos principalmente en la región Huetar Norte de Costa Rica (Cuadro 3). Estos proyectos han permitido mejorar la calidad de los procesos de producción, tanto agrícola como agroindustrial, en los procesos de esterilización, pasteurización, secado y escaldado, el uso de sistemas limpios de producción y la mejora de las condiciones ambientales, por la reducción de la huella de carbono y de la emisión de gases de efecto de invernadero gracias a la transferencia de esta tecnología avanzadas a los procesos de producción rural del país, por lo que los productores de otras zonas del país (Dota, Zarcero, Pérez Zeledón y zona Sur, entre otras) reclamen la aplicación de estos sistemas. Esta vinculación academia-sector productivo-gobierno (instituciones públicas) han permitido la participación tanto de estudiantes costarricenses como de diferentes países, entre ellos España y México y, por medio de una propuesta robusta, solucionar problemas concretos de la práctica productiva de las pequeñas y medianas empresas o asociaciones, lo que constituye clave del éxito de estos proyectos. El grupo de investigación fue galardonado con el premio “National Energy Globe”, de la Fundación Energy Globe (Austria) en 2018 y 2019 por los proyectos “Sistemas solares térmicos para operaciones agrícolas” (Thermal solar systems for farming operations) y “Utilización de energía solar en el proceso de secado de productos agrícolas” (Use of solar energy in the drying process of agricultural products), respectivamente, con los cuales representaron al ITCR. Esperamos que el mismo sea de utilidad para técnicos, ingenieros, productores, empresas, y el sector público

Consumption of aspartame and other artificial sweeteners and risk of cancer in the Spanish multicase‐control study (MCC‐Spain)

Use of artificial sweeteners (AS) such as aspartame, cyclamate, saccharin and sucralose is widespread. We evaluated the association of use of aspartame and other AS with cancer. In total 1881 colorectal, 1510 breast, 972 prostate and 351 stomach cancer and 109 chronic lymphocytic leukaemia (CLL) cases and 3629 population controls from the Spanish Multicase-Control (MCC-Spain) study were recruited (2008-2013). The consumption of AS, from table-top sweeteners and artificially sweetened beverages, was assessed through a self-administered and validated food frequency questionnaire (FFQ). Sex-specific quartiles among controls were determined to compare moderate consumers ( third quartile) vs non consumers (reference category), distinguishing aspartame-containing products and other AS. Unconditional logistic regression models were used to estimate adjusted OR and 95%CI, and results were stratified by diabetes status. Overall, we found no associations between the consumption of aspartame or other AS and cancer. Among participants with diabetes, high consumption of other AS was associated with colorectal cancer (OR=1.58, 95% CI 1.05-2.41, P trend=.03) and stomach cancer (OR=2.27 [0.99-5.44], P trend=.06). High consumption of aspartame, was associated with stomach cancer (OR=2.04 [0.7-5.4], P trend=.05), while a lower risk was observed for breast cancer (OR=0.28 [0.08-0.83], P trend=.03). In some cancers, the number of cases in participants with diabetes were small and results should be interpreted cautiously. We did not find associations between use of AS and cancer, but found associations between high consumption of aspartame and other AS and different cancer types among participants with diabetes

Relevance of gastrointestinal manifestations in a large Spanish cohort of patients with systemic lupus erythematosus: what do we know?

SLE can affect any part of the gastrointestinal (GI) tract. GI symptoms are reported to occur in >50% of SLE patients. To describe the GI manifestations of SLE in the RELESSER (Registry of SLE Patients of the Spanish Society of Rheumatology) cohort and to determine whether these are associated with a more severe disease, damage accrual and a worse prognosis. METHODS: We conducted a nationwide, retrospective, multicentre, cross-sectional cohort study of 3658 SLE patients who fulfil =4 ACR-97 criteria. Data on demographics, disease characteristics, activity (SLEDAI-2K or BILAG), damage (SLICC/ACR/DI) and therapies were collected. Demographic and clinical characteristics were compared between lupus patients with and without GI damage to establish whether GI damage is associated with a more severe disease. RESULTS: From 3654 lupus patients, 3.7% developed GI damage. Patients in this group (group 1) were older, they had longer disease duration, and were more likely to have vasculitis, renal disease and serositis than patients without GI damage (group 2). Hospitalizations and mortality were significantly higher in group 1. Patients in group 1 had higher modified SDI (SLICC Damage Index). The presence of oral ulcers reduced the risk of developing damage in 33% of patients. CONCLUSION: Having GI damage is associated with a worse prognosis. Patients on a high dose of glucocorticoids are at higher risk of developing GI damage which reinforces the strategy of minimizing glucocorticoids. Oral ulcers appear to decrease the risk of GI damage. © The Author(s) 2021. Published by Oxford University Press on behalf of the British Society for Rheumatology

Clonal chromosomal mosaicism and loss of chromosome Y in elderly men increase vulnerability for SARS-CoV-2

The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, COVID-19) had an estimated overall case fatality ratio of 1.38% (pre-vaccination), being 53% higher in males and increasing exponentially with age. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, we found 133 cases (1.42%) with detectable clonal mosaicism for chromosome alterations (mCA) and 226 males (5.08%) with acquired loss of chromosome Y (LOY). Individuals with clonal mosaic events (mCA and/or LOY) showed a 54% increase in the risk of COVID-19 lethality. LOY is associated with transcriptomic biomarkers of immune dysfunction, pro-coagulation activity and cardiovascular risk. Interferon-induced genes involved in the initial immune response to SARS-CoV-2 are also down-regulated in LOY. Thus, mCA and LOY underlie at least part of the sex-biased severity and mortality of COVID-19 in aging patients. Given its potential therapeutic and prognostic relevance, evaluation of clonal mosaicism should be implemented as biomarker of COVID-19 severity in elderly people. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, individuals with clonal mosaic events (clonal mosaicism for chromosome alterations and/or loss of chromosome Y) showed an increased risk of COVID-19 lethality
