Global disparities in surgeons’ workloads, academic engagement and rest periods: the on-calL shIft fOr geNEral SurgeonS (LIONESS) study

: The workload of general surgeons is multifaceted, encompassing not only surgical procedures but also a myriad of other responsibilities. From April to May 2023, we conducted a CHERRIES-compliant internet-based survey analyzing clinical practice, academic engagement, and post-on-call rest. The questionnaire featured six sections with 35 questions. Statistical analysis used Chi-square tests, ANOVA, and logistic regression (SPSS® v. 28). The survey received a total of 1.046 responses (65.4%). Over 78.0% of responders came from Europe, 65.1% came from a general surgery unit; 92.8% of European and 87.5% of North American respondents were involved in research, compared to 71.7% in Africa. Europe led in publishing research studies (6.6 ± 8.6 yearly). Teaching involvement was high in North America (100%) and Africa (91.7%). Surgeons reported an average of 6.7 ± 4.9 on-call shifts per month, with European and North American surgeons experiencing 6.5 ± 4.9 and 7.8 ± 4.1 on-calls monthly, respectively. African surgeons had the highest on-call frequency (8.7 ± 6.1). Post-on-call, only 35.1% of respondents received a day off. Europeans were most likely (40%) to have a day off, while African surgeons were least likely (6.7%). On the adjusted multivariable analysis HDI (Human Development Index) (aOR 1.993) hospital capacity > 400 beds (aOR 2.423), working in a specialty surgery unit (aOR 2.087), and making the on-call in-house (aOR 5.446), significantly predicted the likelihood of having a day off after an on-call shift. Our study revealed critical insights into the disparities in workload, access to research, and professional opportunities for surgeons across different continents, underscored by the HDI

CRISP1 as a novel CatSper regulator that modulates sperm motility and orientation during fertilization

Calcium-dependent mechanisms are critical for successful completion of fertilization. Here, we demonstrate that CRISP1, a sperm protein involved in mammalian fertilization, is also present in the female gamete and capable of modulating key sperm Ca2+ channels. Specifically, we show that CRISP1 is expressed by the cumulus cells that surround the egg and that fertilization of cumulus-oocyte complexes from CRISP1-knockout females is impaired due to a failure of sperm to penetrate the cumulus. We provide evidence that CRISP1 stimulates sperm orientation by modulating sperm hyperactivation, a vigorous motility required for penetration of the egg vestments. Moreover, patch-clamping of sperm revealed that CRISP1 has the ability to regulate CatSper, the principal sperm Ca2+ channel involved in hyperactivation and essential for fertility. Given the critical role of Ca2+ forsperm motility, we propose a novel CRISP1-mediated fine-tuning mechanism to regulatesperm hyperactivation and orientation for successful penetration of the cumulus during fertilization.Fil: Ernesto, Juan Ignacio.

Visiones en educación sin barreras ni fronteras: Un homenaje al Maestro Lorenzo García Aretio

In this paper, the authors will talk about the development of technological platforms and tools that will support the creation and implementation of techno-pedagogical paradigms to tech the XXI Century generations. By proving how the innovative model of the open and distance learning universities (UNAD, for its Spanish acronym) is not run out and can be renewed, taking as an example the COVID-19 pandemic and analyzing the carriers that provide change to a new education, where the need of innovation in higher education in open and distance modalities is an urgent matter. Undoubtedly, learning is one of the human capacities that has most influenced their development and evolution. Thus, the e-education concept is presented as an effort to develop talents and human capacities using the Internet and new information and communication technologies (ICT). This will allow introducing a generalized remote mode, which will create a different culture adjusting the school curriculum to an online strategy, and not a rigid one, that involves technological improvements, so general and specialized knowledge are combined to the needs of scientific, technological, and social development. Teachers work with students differently and provide help through more knowledge and experience. Recent studies are showing that there are more open and online options for teacher professional development and teachers access the Internet to expand their development opportunities through social media platforms. In this sense, the non-attendance process of education has improved its relevance globally. Although, the COVID-19 pandemic caused an accelerator effect on the digital transformation of the educational institutions.   En Visiones en educación sin barreras ni fronteras participaron para su elaboración más de 35 importantes y reconocidos académicos como autores provenientes de toda Iberoamérica, solo por mencionar algunas personalidades que se unieron a este libro homenaje nombraré algunos maestros como Claudio Rama, Julio Cabero, Marta Mena, Santiago Acosta, Francisco Cervantes, Magdalena Cruz, Josep Duart y Antonio Moreira y otros excelsos intelectuales iberoamericanos. Cada análisis que ellos referencian se basa en los diversos tópicos y siempre rigurosos estudios que sobre este apasionante mundo de la innovación educativa ha realizado el Dr. García Aretio y que aparecen reseñados en sus diversos libros y en particular en la insigne revista RIED que hoy él y su equipo han posicionado en lo más alto de los más reconocidos rankings de la élite académica e investigativa mundial.No texto os autores nos falarão do desenvolvimento de plataformas e ferramentas tecnológicas que apoiarão a criação e implantação de paradigmas tecnopedagógicos para educar as gerações do Século XXI, demonstrando como o modelo inovador das universidades abertas e à distância (UNAD) não está esgotado e pode ser renovado, mostrando como exemplo o que aconteceu durante a pandemia de covid-19, analisado os vetores que estão propiciando a mudança para uma nova educação, onde a necessidade de inovação no ensino superior em modalidades abertas e à distância numa questão urgente. A aprendizagem é sem dúvida uma das capacidades humanas que mais influiu no seu desenvolvimento e evolução; por isso, apresentam-nos, a concepção da cibereducação, como um esforço orientado para o desenvolvimento dos talentos e capacidades humanas, com a utilização da Internet e das novas tecnologias da informação e da comunicação (TIC). Isto permitiria implantar uma modalidade à distância generalizada, o que criaria uma cultura diferente, adequando o currículo escolar a uma estratégia digital, e nada rígida, que integre os avanços tecnológicos de uma forma que combina conhecimentos gerais e especializados com as necessidades do desenvolvimento científico, tecnológico e social. Os docentes trabalham com os estudantes de forma diferente e prestam-lhes ajuda com mais conhecimentos e experiência. Os estudos mais recentes mostram que há cada vez mais opções abertas, e on-line, para o desenvolvimento profissional docente, os professores acessam a Internet para ampliar suas oportunidades de desenvolvimento através de plataformas sociais. Neste sentido, as modalidades de ensino não presenciais têm-se tornado cada vez mais importantes a nível mundial. No entanto, foi na sequência da pandemia causada pela covid-19 que se produziu um efeito acelerador na transformação digital das instituições de ensino

Proteasomal degradation of Sfp1 contributes to the repression of ribosome biogenesis during starvation and is mediated by the proteasome activator Blm10

The ribosome transcription activator Sfp1 is degraded by Blm10-proteasomes. Loss of BLM10 results in increased Sfp1 protein levels, increased transcription of ribosomal genes, and increased ribosome levels upon nutrient depletion. Thus Blm10-proteasome-mediated turnover of Sfp1 is a regulatory mechanism for ribosome biosynthesis repression
