Associations between food group intakes and circulating insulin‑like growth factor‑I in the UK Biobank: a cross‑sectional analysis

Purpose Circulating insulin-like growth factor-I (IGF-I) concentrations have been positively associated with risk of several common cancers and inversely associated with risk of bone fractures. Intakes of some foods have been associated with increased circulating IGF-I concentrations; however, evidence remains inconclusive. Our aim was to assess cross-sectional associations of food group intakes with circulating IGF-I concentrations in the UK Biobank. Methods At recruitment, the UK Biobank participants reported their intake of commonly consumed foods. From these questions, intakes of total vegetables, fresh fruit, red meat, processed meat, poultry, oily fish, non-oily fish, and cheese were estimated. Serum IGF-I concentrations were measured in blood samples collected at recruitment. After exclusions, a total of 438,453 participants were included in this study. Multivariable linear regression was used to assess the associations of food group intakes with circulating IGF-I concentrations. Results Compared to never consumers, participants who reported consuming oily fish or non-oily fish ≥ 2 times/week had 1.25 nmol/L (95% confidence interval:1.19–1.31) and 1.16 nmol/L (1.08–1.24) higher IGF-I concentrations, respectively. Participants who reported consuming poultry ≥ 2 times/week had 0.87 nmol/L (0.80–0.94) higher IGF-I concentrations than those who reported never consuming poultry. There were no strong associations between other food groups and IGF-I concentrations. Conclusions We found positive associations between oily and non-oily fish intake and circulating IGF-I concentrations. A weaker positive association of IGF-I with poultry intake was also observed. Further research is needed to understand the mechanisms which might explain these associations.Nuffield Department of Population Health Doctor of Philosophy student scholarshipCancer Research UK C8221/A29017Clarendon Scholarship from the University of OxfordNuffield Department of Population Health Intermediate FellowshipUK Research & Innovation (UKRI)Medical Research Council UK (MRC) MR/M012190/1Thames Valley NIHR Applied Research CentreSpanish Government Spanish State Plan for Scientific and Technical Research and Innovation RYC2020-028818-IGirdlers' New Zealand Health Research Council Fellowship 19/031Wellcome TrustOur Planet Our Health (Livestock, Environment and People -LEAP) 205212/Z/16/ZCancer Research UK Population Research Fellowship C60192/A28516World Cancer Research Fund (WCRF UK), as part of the Word Cancer Research Fund International grant programme 2019/195

On-Campus, Virtual, Blended, and Triple Systems of Teaching-Learning: Fitness and Relevance for Private Universities in Bangladesh

In the transition to the post-pandemic phase, the blended teaching-learning modality seems to be a good solution for universities. But the post-pandemic paradigm seemingly calls for a triple-system of classes, i.e., on-campus classes, blended teaching-learning, and virtual classes separately under separate plans and schedules. The paper explored a clear-cut conceptual understanding of the concepts of “virtual classes,” “blended teaching-learning,” and “triple-system of classes.” The study contributed a comprehensive framework with teaching-learning modalities, especially for private universities in Bangladesh, in the pandemic period, the transition to the post-pandemic period, and the post-pandemic paradigm. It also developed a robust model for blended learning

El Marketing Social: Evaluacion de una campana chilena

68 p.El Marketing Social, es un nuevo concepto de Marketing, el cual utiliza principios y técnicas conocidas con el objetivo de modificar una idea , conducta o practica social, que permita alcanzar el bien común, objetivo ultimo de esta disciplina. Se escogió una campana de cambio social para determinar la relación costo beneficio, para lo cual se utilizo la siguiente metodología: a) Evaluación semiológica de los spots y reportajes de dicha campana. (Modelo semiológicos tienen como finalidad el estudio del lenguaje de los signos). b) Investigación de Mercado, con elaboración de una encuesta que permitiera determinar si la campana publicitaria televisiva consiguió el cambio deseado. La campana publicitaria escogida para la realización de este estudio fue la desarrollada por la institución benefactora Hogar de Cristo, Llamada "50 mil nuevos socios". Del estudio realizado se concluye: La campana publicitaria en estudio logro el objetivo planteado de aumentar el numero de socios, sobrepasando en gran medida la meta propuesta. La televisión influyo, de manera considerable en los nuevos socios, en la decisión de ingresar al Hogar de Cristo, principalmente a través de los reportajes

El rol moderador de la eficacia percibida de las medidas de prevención frente al COVID-19 en la relación entre la percepción de riesgo y la salud mental percibida

The pandemic situation caused by COVID-19 led countries to adopt harsh and prolonged (over time) measures that—along with the high number of infections and deaths and continuous negative information—have affected the mental health of individuals. In this study, the impact on mental health of the COVID-19 health crisis in Spain was explored through the perceived efficacy of pandemic containment measures as a moderator of the relationship that COVID-19 perceived risk establishes with stress and depression. A questionnaire composed of scales conceived to measure COVID-19 perceived risk, perceived efficacy of COVID-19 prevention measures, stress, and depression was completed by 478 adults living in Spain (66.9% females, Mage= 36.30, SD= 15.32) between May 16, 2021, and June 6, 2021. The results confirmed the moderating role of per-ceived efficacy. Perceived efficacy acted as a protective factor for stress and depression by decreasing the negative impact that perceived risk had on both variables related to mentaldistress. Also, the perception that participants had about the effectiveness of prevention measures appeared to be a relevant protective factor regarding mental health during the pandemic. This study highlights the relevance of psychological interventions and government policies that improve positive risk communication and provide adequate information regarding the effectiveness of health-prevention measuresLa pandemia del COVID-19 ha llevado a los países a adoptar severas y prolongadas medidas que junto con el alto número de contagios y muertes y la continua información negativa ha afectado la salud mental de las personas. Este estudio analiza el impacto de la crisis sanitaria del COVID-19 en España explorando el rol moderador de la eficacia percibida de las medidas de contención en la relación que establece la percepción del riesgo del COVID-19 con el estrés y la depresión. Un total de 478 adultos residentes en España (un66.9% mujeres; Medad= 36.30, DT= 15.32) completaron un cuestionario con escalas concebidas para medir el riesgo percibido del COVID-19, la eficacia percibida de las medidas de protección, el estrés y la depresión entre el 16 de mayo y el 6 de junio de 2021. Los resultados confirmaron el rol moderador de la eficacia percibida, la cual actuó como un factor protector del estrés y la depresión al disminuir el impacto negativo que la percepción de riesgo del COVID-19 tiene en ambas variables relacionadas con el distrés mental. La percepción que tienen los individuos sobre la efectividad de las medidas de protección parece ser un factor protector relevante en relación con la salud mental durante una pandemia. Se subraya la relevancia de intervenciones psicológicas y de políticas gubernamentales que mejoren la comunicación positiva del riesgo y la información adecuada sobre la eficacia de las medidas de protección
