Progress test as an assessment for learning approach in an Infectious Diseases Residency Program: a case study.

Assessment is an essential component for all educational programs and must check competence acquirement while foster and promote learning. Progress Test (PT) is well recognized to assess cognitive knowledge, clinical reasoning and decision making in the clinical context, offering important information about the individual performance and program quality. It is widely used in Brazilian and international medical schools; however, it still has little role in assessing medical residents in Brazil. We present the experience of a PT pilot implementation in an Infectious Diseases residency program over two years. The first, second and third-year residents did four serial exams with 40 multiple choice questions (item)/each. Preceptors were trained on best practices on item writing. All the items were reviewed by a panel of experts and, after approval, included in the item bank. All participants answered a survey on their perceptions about the experience. The final score was higher for the third-year residents in all exam applications. The level of satisfaction was high among the participants, who mentioned the learning opportunity with the exam and the feedback. PT can improve residents' assessment along the training period and residents' performance should guide review and improvement of the programs.

El progreso en medicina y la inteligencia artificial / Progress in medicine and artificial intelligence

Resumen Este ensayo cuestiona, a propósito de la medicina, la idea de progreso como desarrollo tecnológico al centrarlo en las personas y no en las cosas. Se analiza cómo el predominio de tal idea de progreso convierte a las sociedades actuales al tecno-fetichismo que degrada la vida comunitaria y la práctica médica contribuyendo a la medicalización de la vida social. Se argumenta que la realización de las potencialidades tecnológicas depende de sus formas de uso, que el móvil principal del desarrollo tecnológico es el lucro sin límites, y que los desarrollos prioritarios son los que potencian el control social que mantiene el statu quo. Se critica la idea de inteligencia como cociente intelectual al proponerla como atributo del ser humano como un todo, manifiesto en las formas pensar y proceder de las personas en sus circunstancias, donde la afectividad y el pensamiento crítico son imprescindibles para su desarrollo. Se destaca que su antecedente es el concierto armónico de la vida planetaria contrastante con la disarmonía humana imperante. Se plantea que la inteligencia artificial es la más reciente hechura del tecno-fetichismo que deposita en la tecnología atributos vitales, y que sus formas de uso acentuarán la degradación de la vida humana y planetaria. Se propone otra idea de progreso médico basado en formas de organización propicias para el desarrollo de aptitudes inquisitivas, críticas y colaborativas que impulsen la superación permanente, cuyo horizonte lejano es el progreso dignificante: sublimación espiritual, intelectual, moral y convivencial de las colectividades en armonía con el ecosistema planetario.

Abstract This essay questions, with regard to medicine, the idea of progress as technological development by focusing on people rather than things. It analyzes how the predominance of such an idea of progress converts today’s societies to techno-fetishism that degrades community life and medical practice, contributing to the medicalization of social life. It is argued that the realization of technological potentialities depends on their forms of use; that the main motive of technological development is unlimited profit and that priority developments are those that enhance the social control that maintains the status quo. The intelligence as an intelligence quotient is criticized by proposing it as an attribute of the human being as a whole, manifested in the ways of thinking and proceeding of people in their circumstances, where affectivity and critical thinking are essential for their development; it is emphasized that its antecedent is the harmonic concert of planetary life that contrasts with the prevailing human disharmony. It is proposed that artificial intelligence is the most recent creation of techno-fetishism that deposits vital attributes in technology and that its forms of use will accentuate the degradation of human and planetary life. Another idea of medical progress is proposed, based on forms of organization conducive to the development of inquisitive, critical and collaborative skills that promote permanent improvement, whose distant horizon is dignifying progress: spiritual, intellectual, moral and convivial sublimation of collectivities in harmony with the planetary ecosystem.

Progress in medicine and artificial intelligence.

This essay challenges the idea of progress as technological development in relation to medicine by focusing on people rather than things. It analyzes how the prevalence of such an idea of progress leads contemporary societies to a technofetishism that degrades community life and medical practice, contributing to the medicalization of social life. It is argued that the realization of technological potentialities depends on their forms of use, that the main motive of technological development is unlimited profit, and the priority developments are those that enhance social control which maintains the status quo. Intelligence as an intelligence quotient is criticized by proposing it as an attribute of the human being as a whole, manifested in the ways of thinking and acting of human beings in their circumstances, where affectivity and critical thinking are essential for their development; it is emphasized that its antecedent is the harmonic concert of planetary life, which contrasts with the prevailing human disharmony. It is proposed that artificial intelligence is the latest creation of technofetishism, which deposits vital attributes in technology, and that its use will accentuate the degradation of human and planetary life. Another idea of medical progress is proposed, based on forms of organization that is conducive to the development of inquisitive, critical, and collaborative skills that promote permanent improvement, whose distant horizon is dignified progress: the spiritual, intellectual, moral, and convivial sublimation of collectivities in harmony with the planetary ecosystem.

Efficacy and safety of metronomic oral vinorelbine and its combination therapy as second- and later-line regimens for advanced non-small-cell lung cancer: a retrospective analysis.

OBJECTIVE: This retrospective analysis aimed to evaluate the efficacy and adverse reactions of metronomic oral vinorelbine and its combination therapy as second- and later-line regimens for advanced non-small-cell lung cancer (NSCLC). METHODS: NSCLC patients undergoing metronomic oral vinorelbine as second- and later-line regimens in Fujian Cancer Hospital from October 2018 to October 2022 were enrolled, and patients' demographic and clinical characteristics were collected. The efficacy and safety of metronomic oral vinorelbine monotherapy and its combination therapy regimens were compared. RESULTS: Of 57 study subjects, 63.2% received third- and later-line therapy, with median progression-free survival (mPFS) of 4 months, overall response rate (ORR) of 10.5%, and disease control rate (DCR) of 80.7%. The incidence of therapy-related adverse events was 42.1%, and there was only one case presenting grades 3 and 4 adverse events (1.8%). Among driver gene-negative participants, vinorelbine combination therapy regimens achieved longer mPFS (4.6 vs. 1.2 months, hazards ratio = 0.11, P < 0.0001) and comparable toxicity in relative to metronomic oral vinorelbine, and metronomic oral vinorelbine combined with immune checkpoint inhibitors showed the highest response, with mPFS of 5.6 months (95% CI 4.8 to 6.4 months), ORR of 25%, and DCR of 81.3%. Among participants with gradual resistance to osimertinib, continuing osimertinib in combination with metronomic oral vinorelbine achieved mPFS of 6.3 months (95% CI 0.1 to 12.5 months) and DCR of 86.7%. CONCLUSION: Metronomic oral vinorelbine and its combination therapy regimens are favorable options as second- and later-line therapy for advanced NSCLC patients, with acceptable efficacy and tolerable toxicity. Vinorelbine combination therapy regimens show higher efficacy and comparable toxicity in relative to metronomic oral vinorelbine, and metronomic oral vinorelbine may have a synergistic effect with immunotherapy and EGFR-TKI targeted therapy.

Predicting students' academic progress and related attributes in first-year medical students: an analysis with artificial neural networks and Naïve Bayes.

BACKGROUND: Dropout and poor academic performance are persistent problems in medical schools in emerging economies. Identifying at-risk students early and knowing the factors that contribute to their success would be useful for designing educational interventions. Educational Data Mining (EDM) methods can identify students at risk of poor academic progress and dropping out. The main goal of this study was to use machine learning models, Artificial Neural Networks (ANN) and Naïve Bayes (NB), to identify first year medical students that succeed academically, using sociodemographic data and academic history. METHODS: Data from seven cohorts (2011 to 2017) of admitted medical students to the National Autonomous University of Mexico (UNAM) Faculty of Medicine in Mexico City were analysed. Data from 7,976 students (2011 to 2017 cohorts) of the program were included. Information from admission diagnostic exam results, academic history, sociodemographic characteristics and family environment was used. The main dataset included 48 variables. The study followed the general knowledge discovery process: pre-processing, data analysis, and validation. Artificial Neural Networks (ANN) and Naïve Bayes (NB) models were used for data mining analysis. RESULTS: ANNs models had slightly better performance in accuracy, sensitivity, and specificity. Both models had better sensitivity when classifying regular students and better specificity when classifying irregular students. Of the 25 variables with highest predictive value in the Naïve Bayes model, percentage of correct answers in the diagnostic exam was the best variable. CONCLUSIONS: Both ANN and Naïve Bayes methods can be useful for predicting medical students' academic achievement in an undergraduate program, based on information of their prior knowledge and socio-demographic factors. Although ANN offered slightly superior results, Naïve Bayes made it possible to obtain an in-depth analysis of how the different variables influenced the model. The use of educational data mining techniques and machine learning classification techniques have potential in medical education.

PT can improve residents' assessment along the training period and residents' performance should guide review and improvement of the programs.

Reliability across content areas in progress tests assessing medical knowledge: a Brazilian cross-sectional study with implications for medical education assessments

ABSTRACT BACKGROUND: Brazilian medical schools equitably divide their medical education assessments into five content areas: internal medicine, surgery, pediatrics, obstetrics and gynecology, and public health. However, this division does not follow international patterns and may threaten the examinations' reliability and validity. OBJECTIVE: To assess the reliability indices of the content areas of serial, cross-institutional progress test examinations. DESIGN AND SETTINGS: This was an analytical, observational, and cross-sectional study conducted at nine public medical schools (mainly from the state of São Paulo) with progress test examinations conducted between 2017 and 2023. METHODS: The examinations covered the areas of basic sciences, internal medicine, surgery, pediatrics, obstetrics and gynecology, and public health. We calculated reliability indices using Cronbach's α, which indicates the internal consistency of a test. We used simple linear regressions to analyze temporal trends. RESULTS: The results showed that the Cronbach's α for basic sciences and internal medicine presented lower values, whereas gynecology, obstetrics, and public health presented higher values. After changes in the number of items and the exclusion of basic sciences as a separate content area, internal medicine ranked highest in 2023. Individually, all content areas except pediatrics remained stable over time. CONCLUSIONS: Maintaining an equitable division in assessment content may lead to suboptimal results in terms of assessment reliability, especially for internal medicine. Therefore, content sampling of medical knowledge for general assessments should be reappraised.

Evaluation of the implementation progress through key performance indicators in a new multimorbidity patient-centered care model in Chile.

BACKGROUND: Complex health interventions involve deep organizational, structural, and cultural changes that challenge health teams and decision-makers. The explosion of chronic diseases has made the multimorbidity approach a global priority. The Centro de Innovación en Salud ANCORA UC implemented a Multimorbidity Patient-Centered Care Model in the Chilean public health system. OBJECTIVE: This study aims to evaluate the progress of the implementation of the Multimorbidity Patient-Centered Care Model in seven primary care centers through key performance indicators. METHODS: a set of indicators was designed to evaluate change management, operations, installation of new roles, and services and activities of the intervention strategy of the model. Key performance indicators were identified to monitor the implementation progress on minimal components for the model's sustainability. Each item was assigned against an expected minimum score of 67% of progress from the overall score. They were monitored twice in seven primary health centers in 2019 and 2020, which intervened 22,642 patients with the intervention. RESULTS: The results showed that six of the seven primary care centers reached the minimum implementation threshold. The main advances were in operational conditions, and those with minor progress in implementation were the clinical services. Population size, organization, coordination of the health care teams, additional training, and decision-makers support were key factors that determined the degree of progress in a complex intervention. CONCLUSION: It was possible to measure the progression of the implementation of a complex intervention through key performance indicators delivering relevant information for decision-makers that pursue a successful and faithful implementation. This study provides a valuable tool for the national scale-up of a similar model started in Chile by the Ministry of Health and other countries.

Educación y conocimiento liberador.

This essay begins with an aphorism on education: "forger of the liberating forces towards the progress of the human condition", in its spiritual, intellectual, moral and convivial connotation in harmony with the planetary ecosystem (dignifying progress). It highlights the coincidence of the highest historical levels of professional education with the extreme degradation of Western culture, which reveals the role of education that favors passivity in the face of knowledge and the prevailing order. The characteristics of passive education are contrasted with those of participatory education based on the development of critical thinking. Critical thinking is defined and the type of educational environment that stimulates and channels it is argued, in particular the complex and integrative thinking alluding to the self projected to who we are and where we are, absent in reductionist science. Liberating knowledge is specified and its purpose defined as "to understand ourselves as fraternal humanity and to find our place in harmony with the infinitely diverse concert of the living world". The theoretical revolutions -now dismissed- being seeds of liberating knowledge that revealed anthropocentrism and ethnocentrisms as "prisons of the spirit" are synthesized. It is concluded that liberating knowledge fulfills the utopian role of signaling the endless walking towards dignifying human progress.

Este ensayo inicia con un aforismo sobre la educación: «forjadora de las fuerzas liberadoras hacia el progreso de la condición humana¼, en su connotación espiritual, intelectual, moral y convivencial en armonía con el ecosistema planetario (progreso dignificante). Se realza la coincidencia de las mayores cotas históricas de educación profesional con la extrema degradación de la cultura occidental, reveladora del papel de la educación que favorece la pasividad ante el conocimiento y el orden imperante. Se contrastan los caracteres de la educación pasiva con los de la participativa basada en el desarrollo del pensamiento crítico. Se define el pensamiento crítico y se argumenta el tipo de ambiente educativo que lo estimula y encauza, en particular, el pensamiento complejo e integrador alusivo al sí mismo proyectado al quiénes somos y dónde estamos, ignorado por la ciencia reduccionista. Se especifican el conocimiento liberador y su finalidad: «entendernos como humanidad fraterna y encontrar nuestro lugar en armonía con el concierto infinitamente diverso del mundo viviente¼. Se sintetizan las revoluciones teóricas ­hoy desestimadas­, simientes del conocimiento liberador que develaron al antropocentrismo y a los etnocentrismos como «prisiones del espíritu¼. Se concluye que el conocimiento liberador cumple el papel utópico de orientar y señalizar el caminar interminable hacia el progreso dignificante.

Reflexões sobre a utilização do Teste de Progresso na avaliação programática do estudante / Reflections on the use of the Progress Test in the programmatic student assessment

Resumo: Introdução: O Teste de Progresso (TP) constitui modalidade estabelecida e bem-sucedida de avaliação de conhecimentos do estudante das profissões da saúde, principalmente os de Medicina, com potencial de contribuir substancialmente para as finalidades formativa e informativa (controle de qualidade e indicação de melhoria nos processos de ensino e aprendizagem). Adicionalmente, o TP apresenta características adequadas à sua inclusão em sistemas institucionais de avaliação que privilegiem a finalidade formativa, como a avaliação programática (AP), mas que cumprem também a somativa. Nas escolas que vêm definindo ações visando à introdução da AP em seus cursos de graduação, é necessária a reflexão sobre as fortalezas e limitações da utilização do TP no sistema de avaliação. Desenvolvimento: A partir das considerações de um grupo de trabalho representativo de toda a instituição, incumbido de propor meios de introdução da AP em um novo currículo para o curso de Medicina, contando com assessoria internacional com experiência tanto no TP como na AP, elaborou-se reflexão sobre esse tema, baseada na experiência dos autores e em dados da literatura. Propõe-se que, dentro da perspectiva longitudinal da AP, o TP constitua um dos pilares na avaliação de conhecimentos. O TP pode servir de base para acompanhamento do estudante, no contexto da sua turma (coorte), e seus resultados devem ser discutidos com o mentor que o acompanha e lhe dá suporte. O TP deve ter também papel central na gestão, como fonte de informações para eventual revisão e qualificação do currículo e das suas atividades de ensino e aprendizagem. É previsível que a utilização do TP na AP traga diferentes desafios e barreiras, que serão mais facilmente superados se houver na instituição experiências já consolidadas de aplicação de exames institucionais e de desenvolvimento docente para a elaboração de questões objetivas de boa qualidade. Conclusão: A efetividade do TP dentro do sistema institucional de AP vai depender de medidas que visem aumentar a sua efetividade na avaliação e que estimulem a participação ativa do estudante, refletindo sobre seu desempenho no TP, com o apoio do seu mentor, de modo a se engajar em ações que fomentem a autorregulação da aprendizagem.

Abstract: Introduction: The Progress Test (PT) is a well-established and mostly successful modality of student knowledge assessment in the health professions, mainly those in the medical area, with the potential to contribute substantially to the formative and informative purposes (quality control and indication of improvement in the teaching-learning processes). Additionally, the PT has characteristics that are adequate for its inclusion in institutional evaluation systems that facilitate the formative purpose, such as programmatic assessment (PA), but that also meet the summative purpose. In schools that have defined actions aimed at introducing PA in their undergraduate courses, it is necessary to reflect on the strengths and limitations of using PT in the evaluation system. Development: based on the considerations of a working group representative of the entire institution, tasked with proposing means of introducing PA in a new curriculum for the medical course, with international advice with experience in both PT and PA, we generated a reflection on this topic, based on the authors' experience and data from the literature. It is proposed that, within the longitudinal perspective of the PA, the PT constitutes one of the pillars in the assessment of knowledge. The PT can be used as a basis for monitoring the students, in the context of their class (cohort), and its results should be discussed with the mentors who accompanies and supports them. The PT must also play a central role in management, as a source of information for eventual review and qualification of the curriculum and its teaching-learning activities. It is predictable that the use of the PT in PA will bring different challenges and barriers, which will be more easily overcome if the institution has already consolidated experiences in the application of institutional exams and in faculty development for the production of good quality objective questions. Conclusion: the effectiveness of the PT within the institutional PA system will depend on measures aimed at increasing its effectiveness in the assessment and that encourage the student's active participation, reflecting on their performance in the PT, with the support of their mentor, aiming to engage in actions that encourage learning self-regulation.

Genetic parameters and genetic trends for production traits in dairy Gir cattle / Parâmetros genéticos e tendências genéticas de características de produção de bovinos Gir Leiteiro

The objective of this research was to estimate genetic parameters and genetic trends (GT) for 305-day milk yield (MY305) and 305-day fat yield (FY305) of purebred Dairy Gir animals of the National Dairy Gir Breeding Program. The restricted maximum likelihood method was used in an animal model. GT were obtained via linear regression and divided into two periods (1935-1992 and 1993-2013 for PL305; 1935-1992 and 1993-2010 for MY305). The estimated heritabilities were 0.23 (MY305) and 0.10 (FY305). The GT (kg/year) values for MY305 in the 2nd period for measured females (25.49), females (26.11), and males (35.13) were higher than those found in the 1st period (2.52; 2.06, and 1.00, respectively). The heritability estimated for MY305 confirmed the possibility of genetic improvement by selection and indicated a lower additive genetic effect on FY305 of purebred animals. The genetic progress for MY305 in all purebred population is denoted by the more expressive gains found from 1990's, when the first bull catalogs were published.

Objetivou-se estimar os parâmetros genéticos e tendências genéticas (GT) para produção de leite (MY305) e produção de gordura (FY305), ambas em 305 dias, de animais puros Gir Leiteiro, integrantes do Programa Nacional de Melhoramento do Gir Leiteiro. Foi utilizada a metodologia da máxima verossimilhança restrita em modelo animal. As GT foram obtidas via regressão linear e divididas em dois períodos (1935-1992 e 1993-2013 para PL305; 1935-1992 e 1993-2010 para MY305). As herdabilidades foram de 0,23 (MY305) e 0,10 (FY305). Para PL305, as GT (kg/ano) do 2º período para fêmeas mensuradas (25,49), fêmeas (26,11) e, machos (35,13) foram claramente superiores às do 1º período (2,52; 2,06 e 1,00; respectivamente). A estimativa de herdabilidade para MY305 reafirma ser possível melhoramento genético por meio de seleção, enquanto para FY305 sugere uma menor influência genética aditiva em animais puros. O progresso genético para MY305 em toda a população pura está evidenciado pelos ganhos mais expressivos, observados a partir da década de 90, quando foram divulgados os primeiros sumários de touros.

The contribution of a MOET nucleus scheme for the improvement of Guzerá (Bos indicus) cattle for milk traits in Brazil.

The Guzerá breed evolved from the introduction of breeds from India, mainly the Kankrej breed, into Brazilian livestock at the end of the 19th century. Guzerá adapted well to the climatic conditions of Brazil, where it is considered a dual-purpose breed and has been used for pasture-based beef, milk or dual-purpose production systems with the use of low-medium inputs. The importance of this genetic resource for milk production in tropical regions moved breeders to implement the National Breeding Program for the Improvement of Guzerá in 1994, based on both progeny testing and MOET nucleus schemes. We sought to evaluate the role of the MOET nucleus scheme in the phenotypic and genetic progress for milk traits in this breed. The initial database used in the present study consisted of 6,513 cows, daughters of 761 bulls. We performed genetic evaluations with different datasets using a linear mixed model in a single trait analysis, including the relationship matrix, in order to estimate breeding values. Inbreeding coefficients were also calculated using the relationship of descent between two parents. Annual phenotypic, genetic and inbreeding trends were obtained for each dataset, considering the genetic pathways of both the bull and the cow. The low genetic progress found for milk yield in the whole population (5.27 ± 0.30 kg/year) partially accounted for the dual-purpose selection goal, despite the higher genetic progress in the MOET nucleus (9.39 ± 0.79 kg/year). The inbreeding coefficient was minimized at the beginning of the breeding program based on the use of new lineages. Posteriorly, it started increasing again from 0.002 in 1991 to 0.008 in 2019. The results provided evidence of the significant contribution of the MOET nucleus scheme for the phenotypic and genetic progress of Guzerá breed for milk traits, as well as of the impact of the breeding program on the inbreeding coefficient rate in the early years. New strategies need to be designed for the Guzerá breed, to allow for greater improvement of milk traits and minimizing the rate of the inbreeding coefficient.

A social cognitive perspective on occupational identity development in college students.

Occupational identity is a central concept of career development, by providing a sense of direction and meaning across career development. This study aimed to examine how this concept can be associated with career processes through model formed by a set of socio-cognitive factors. The participants were 358 college students at a Brazilian university who completed measures of occupational identity, environmental supports and barriers, self-efficacy, goal progress, and academic satisfaction. Analysis indicates that the occupational identity status was partially well predicted by the combination of self-efficacy to cope with barriers, supports, academic satisfaction, and goal progress. These results highlight that students with a positive sense of competencies to deal with barriers and adequate levels of academic satisfaction would easily establish an occupational identity.

Tendencias actuales en la enseñanza de la reanimación cardiopulmonar básica / Current trends in the teaching of basic cardiopulmonary resuscitation / Current trends in the teaching of basic cardiopulmonary resuscitation

Introducción: La enseñanza de la reanimación cardiopulmonar se basa en el estudio de conceptos, teorías y prácticas que son evaluados con el objetivo de medir el nivel de retención de los individuos. Objetivo: Caracterizar el impacto de las tendencias actuales en la enseñanza de la reanimación cardiopulmonar básica. Métodos: Se realizó una revisión bibliográfica de artículos científicos pertenecientes a las bases de datos Medline, PubMed, SciELO Regional y SciELO Cuba. Se utilizaron descriptores en español e inglés y se revisaron 29 citas. Resultados: Las tendencias actuales implican la aplicación de las nuevas tecnologías, la autopreparación y el poco desarrollo de entornos presenciales. Se consideran las escuelas como lugares clave para las nuevas formas de enseñanza. Los simuladores permiten la formación bajo situaciones clínicas reales. El autoaprendizaje garantiza la consolidación de las habilidades prácticas trasmitidas por el instructor y asimiladas por el estudiante. Conclusiones: La reanimación cardiopulmonar garantiza una mejor calidad de vida de la población en general. Con el avance tecnológico se ha abierto una nueva etapa en la formación de habilidades, donde ha primado la autonomía; aunque existen notables desventajas. Entonces se necesita un asesoramiento con instructor, que ofrezca los conocimientos teóricos y prácticos básicos compaginados con un nivel de autonomía del aprendizaje. Este proceso debe seguirse y controlarse. A la vez que la formación no se detiene ahí, la formación sistemática en cualquier lugar permite la reafirmación de lo aprendido. De este modo, los avances tecnológicos desempeñarán su mejor beneficio(AU)

Descriptors in Spanish and English were used, as well as 29 citations were reviewed. Results: Current trends involve the application of new technologies, self-training and little development of face-to-face settings. Schools are considered as key places for new forms of teaching. Simulators allow training under real clinical situations. Self-learning guarantees the consolidation of practical skills transmitted by the instructor and assimilated by the student. Conclusions: Cardiopulmonary resuscitation guarantees better quality of life for the general population. Technological progress has opened a new stage in the training of skills, in which autonomy has prevailed; however, there are significant disadvantages. Therefore, there is a need for instructor-led counseling, offering basic theoretical and practical knowledge combined with a level of learning autonomy. This process must be monitored and controlled. While training does not stop at such point, systematic training at any location allows reaffirmation of what has been learned. In this way, technological advances will permit to take the best advantage(AU)

Dataset of historic and modern bread and durum wheat cultivar performance under conventional and reduced tillage with full and reduced irrigation.

Conservation agriculture (CA) is an agronomic management system based on zero tillage and residue retention. Due to its potential for climate change adaptation through the reduction of soil erosion and improved water availability, CA is becoming more important in many regions of the world. However, increased bulk density and large amounts of crop residues may be a constraint for early plant establishment. This holds especially true under irrigated production areas with high yield potential. Genotype × tillage effects on yield are not well understood and it is unclear whether tillage should be an evaluation factor in breeding programs. Fourteen CIMMYT bread (Triticum aestivum) and thirteen durum (Triticum turgidum) wheat genotypes, created between 1964 and 2011, were tested for yield and agronomic performance at CIMMYT's experimental station near Ciudad Obregon, Mexico, during nine seasons. The genotypes were subjected to different tillage and irrigation treatments which consisted of conventional and permanent raised beds with full and reduced irrigation. The dataset includes traits collected during the growing period (days to emergence, days to flowering, maturity, plant height, NDVI, days from flowering to maturity, grain production rate) and at harvest (yield, harvest index, thousand grain weight, spikes/m², grains/m², test weight) and weather data (daily minimum and maximum temperature, rainfall). Six years of data of 26 genotypes were published along with the Honsdorf et al. (2018) paper in Field Crops Research (DOI: s10.1016/j.fcr.2017.11.011). This updated dataset includes three additional seasons of data (harvest years 2016 to 2018) and an additional bread wheat genotype (Borlaug100).

Ramularia leaf spot and boll rot are affected differently by organic and inorganic nitrogen fertilization in cotton plants

Interaction among nitrogen fertilization using bovine manure, poultry manure, Jatropha curcas seed cake and urea, and the diseases Ramularia leaf spot (RLS) and Boll rot (BR), caused by Ramulariopsis pseudoglycines and Diplodia gossypina, respectively, in cotton plants (Gossypium hirsutum L.), was studied under field conditions. Intensity (incidence and severity in percentage) of RLS and incidence (%) of BR were evaluated over time, starting in reproductive stage B1 (first visible flower bud). A randomized complete block design with a 4x4 factorial arrangement was used (fertilizers x doses), totaling 16 treatments with four replications. Disease progress was analyzed with the nonlinear Logistic and Gompertz models, obtaining the epidemiological parameters amount of initial disease (Y0) and progress rate (r). Plants fertilized with 50 kg N ha-1, presented an incidence twice greater than those obtained with other fertilizers. The Logistic model better fits RLS, but no model could represent BR. Only the epidemiological parameters of RLS were affected differently in this experiment compared to BR disease. The possible role of organic and inorganic nitrogen fertilization in the RLS and BR management is discussed.

Factor analysis of the performance at the medical residency exam, progress test and clerkship rotations performance coefficient / Análise fatorial do desempenho no exame de residência médica, teste de progresso e coeficiente de desempenho nos estágios do internato

Abstract: Introduction: The relationships between the students' performance on medical residency exams and progress tests and medical clerkship rotations are not well established. Objective: The objective of this study was to measure the correlations between grades on progress tests and clerkship rotations assessments and the medical residency exam and determine which performance had the strongest correlation with the final medical residency exam. Methods: This was a retrospective and longitudinal study with correlation analyses of grades on progress tests from the 1st to 6th year of medical school, the clerkship rotations performance coefficient (5th and 6th years of school) and the final medical residency exam in a cohort of students enrolled in a federal public medical school using factor analysis. Students who performed the progress tests from the 1st to 6th year were included. Results: Of 123 students enrolled in the first year of medical school in 2009, 114 (92.7%) performed the progress tests during the six years and were included. The average grades on the progress tests from 1 to 10 were 2.67 (1st year), 3.01 (2nd year), 4.19 (3rd year), 4.01 (4th year), 5.19 (5th year), and 6.38 (6th year). The average grades in the clerkship rotations were 8.32 (5th year) and 8.26 (6th year). The average score on the theoretical medical residency exam was 7.53 and the final result of the medical residency exam was 8.05. Factor analysis detected three domains with greater correlation strength that accounted for 76.3% of the model variance. Component 1 was identified as the coefficient of academic performance (CAP) 5th, CAP 6th and final medical residency exam grades, whereas component 2 was constituted by the grades of the 5th and 6th years progress tests and the third component comprised the progress tests of the 2nd, 3rd and 4th years. Conclusions: Grades on the progress tests, the clerkship rotations assessments and the final medical residency exam were correlated. Moreover, the performance during the medical clerkship rotations showed the strongest correlations with medical residency exam grades.
