Calcium levels and calcium:available phosphorus ratios in diets for white egg layers from 42 to 58 weeks of age

The experiment was conducted to determine the nutritional requirement of calcium and the best calcium:available phosphorus ratio for commercial layers at the post-laying peak. A total of 324 Hy-Line W-36 laying hens were utilized in the period from 42 to 58 weeks of age, distributed in a completely randomized design in a 3 × 3 factorial arrangement, composed of three levels of calcium (39, 42 and 45 g/kg) and three calcium:phosphorus ratios (12.12:1; 10.53:1; and 9.30:1), totaling nine treatments with six replications and six birds per experimental unit. There was no significant effect from the calcium levels × calcium:phosphorus ratio interaction for any of the variables studied. The calcium levels and the calcium:phosphorus ratios did not affect the variables performance or egg and bone quality. At the evaluation of the calcium:phosphorus balance, as the levels of calcium of the diet were raised, the intake of calcium and phosphorus and the contents of mineral matter and calcium in the excreta increased linearly, and the retention of calcium by birds decreased linearly. With the reduction of the calcium:phosphorus ratios of the diet, intake, retention and excretion of phosphorus by layers increased. Diets containing calcium at 39 g/kg and a calcium:phosphorus ratio of 12.12:1, corresponding to an increase in calcium of 3.51 g/bird/day and available phosphorus of 289 mg/bird/day, meet the requirements of calcium and available phosphorus of white egg layers in the period from 42 to 58 weeks of age

The prevention of arboviral diseases using mobile devices: a preliminary study of the attitudes and behaviour change produced by educational interventions

Objectives In Brazil, the National Policy for Dengue Control seeks to incorporate the lessons of national and international experience in dengue control, emphasizing the need for health education activities. The objective of this study was to evaluate and compare knowledge, attitudes and behaviours related to the prevention of arboviruses before and after a two‐month educational intervention using a learning platform on mobile devices. Methods This quasi‐experimental study corresponds to the first phase of the project "Impact of mobile learning in the prevention and management of complications caused by arboviruses (Zika, Dengue, Chikungunya) – ZIKAMOB”, sponsored as part of the British Council Newton Fund. Results Thirty of the 93 participants were first‐year undergraduate university students (36.7% male) and 63 were police officers (84.1% male). The pattern of attitudes and behaviour was very similar in both groups before the intervention. The students changed their attitudes and behaviour (p=0.032) in relation to their engagements in actions for the prevention of arboviral diseases and several other activities related to house inspections and precautions with water tanks (p<0.01). However, recycling and surveillance activities were not as effective in changing behaviour. Female participants showed more motivation to participate in preventive activities, but living alone and working were barriers to participation. Individuals who already perform selective waste collection and are cultivating gardens demonstrated both a positive attitude and positive behaviour towards actions for the prevention of arboviral diseases. Conclusion Mobile learning and behaviour change theories might be successful as the basis for school‐based and community‐based interventions to avoid arboviruses. These outcomes need to be confirmed in broader future studies

The aim of this study was to evaluate the behavioural change of high school students and teachers who participated in an educational intervention for the prevention and vector control of arboviral diseases. Methods: In this school-based intervention, a self-reported questionnaire was used in a pre-post intervention methodology to assess environmental risk factors, sociodemographic variables and to measure attitudes and behaviours. In all, 883 high school students and teachers from the city of Campina Grande, in the state of Paraíba, northeastern Brazil, participated. The e-health intervention consisted of a competition between schools to comply with preventive actions via content production for social networks, and the monitoring was performed over a period of three months through the ZikaMob software developed by the researchers. Results: Out of the 883 survey participants, 690 were students ranging in age from 14 to 41 years, with an average of 17 ± 2 years; and 193 were teachers from 22 to 64 years old, averaging 38 ± 9 years. The analysis of the data shows that significant differences in most of the target behaviours were apparent after the intervention, with an increase of about 10% in the performance of inspection actions; a 7% greater separation of recyclables and a 40% increase in the screening of windows among students. Students showed lower fear of, and a lower self-perception of the risk of, acquiring arboviruses than teachers on average. Conclusions: ZikaMob is an innovative strategy with the potential to be replicated in any location that has an internet network and can involve an unlimited number of participants.This study was financed in part by the Coordenação de Aperfeiçoamento de Pessoal de Nível Superior – Brasil (CAPES) (Finance Code 001), Universidade Estadual da Paraíba (UEPB), Fundação de Apoio à Pesquisa do Estado da Paraíba (FAPESQ) (Grant 02/2017), British Council Newton Fund Institutional Links (Grant 274560199).Accepted versio

Control sustentable del vector del HLB en la Agricultura Familiar en Argentina, Uruguay, Paraguay y Bolivia

Póster presentado en el IX Congreso Argentino de Citricultura, 11 al 14 de junio de 2019, San Miguel de Tucumán, Tucumán, Argentina.El Huanglongbing (HLB), enfermedad causada por una bacteria (Candidatus Liberibacter spp), es la más importante de la citricultura mundial debido a que no tiene cura. La prevención se basa en uso de material sano, el monitoreo constante del cultivo, el insecto vector (Diaphorina citri) y su control. La identificación temprana de la planta infectada y su eliminación contribuye a disminuir la diseminación de esta enfermedad. Se presentó un proyecto para abordar esta problemática en la convocatoria Fontagro 2018, mediante la conformación de una plataforma integrada por INTA/Fundación ArgenINTA (Argentina) como ejecutor, e INIA (Uruguay), la Universidad Nacional de Itapuá (Paraguay) y el Gobierno Autónomo de Bermejo (Bolivia) como co-ejecutores. Participan además como Organismos Asociados al proyecto: SENASA y FEDERCITRUS de Argentina y UPEFRUY de Uruguay y se cuenta con 26 notas de adhesión de otras instituciones públicas y privadas. La finalidad del proyecto es prevenir el avance del HLB en la región para evitar la ruptura del entramado socioeconómico y productivo que constituye la cadena citrícola, que en su etapa primaria cuenta con 180 mil ha con cítricos y más de 6.000 agricultores familiares. Para ello se propone adaptar, difundir y concientizar la tecnología de manejo integrado de plagas (MIP) en el control del vector del HLB de los cítricos en la agricultura familiar (AF) en países de la plataforma.El proyecto se organiza en cuatro componentes: 1. Control del vector del HLB en un contexto de adaptación local de manejo integrado, mediante instalación de 17 lotes demostradores (LD) en establecimientos de productores familiares de los países de la plataforma; 2. Capacitación a familias productoras y profesiones, formación de monitoreadores con certificación, comunicación y concientización social; 3. Monitoreo de sustentabilidad, calidad y análisis económico en los LD; y 4. Gestión colectiva de la innovación. Inicio a mediados de 2019.

Association between biopsychosocial factors and self-reported COVID-19 clinical complications in a Brazilian city

Funding Information: This research was funded by the Office of Research and Graduate Studies of the Universidade Federal de Alfenas (MG), grant number 002/2020. Publisher Copyright: © 2022 Epidemio is a publication of Associação Brasileira de Saúde Coletiva - ABRASCO.Objective: This study aimed to analyze the existence of an association between the biopsychosocial profile of people affected and the number of self-reported clinical complications from COVID-19 in a Brazilian city. Methods: This is a cross-sectional (baseline) study, nested in a cohort study, carried out with 217 confirmed cases of COVID-19, interviewed from January to October 2021, during home visits, in a city in the south of Minas Gerais, Brazil. A structured questionnaire with the KoboToolbox resource was used. The independent variables were sociodemographic and clinical profile (comorbidities), quality of life, post-traumatic stress, anxiety, depression, and social support. The dependent variable was the number of self-reported clinical complications from COVID-19. The multivariate linear regression technique was adopted for the analyses. Results: The participants reported multiple clinical complications from COVID-19. There were “four or more” complications in 94.6% of the cases. Having a history of high blood pressure was associated with more complications post-SARS-CoV-2 infection, whereas having a caregiver and presenting with post-traumatic stress were associated with fewer COVID-19 complications. Conclusion: The multisystemic nature of the complications caused by COVID-19 and the associations identified emphasizes the need for an integrated approach to patients and for studies that monitor the effects of the disease on the demands placed on health systems, aiming to better understand and address them.publishersversionpublishe

The published version can be accessed at the following link on the publisher’s website: https://ccsenet.org/journal/index.php/gjhs/article/view/0/47625According to the World Health Organization, intervention actions and Health Education achieve better performance when based on Behavior Change Theories associated with new technologies. This work aimed to build and validate an Audiovisual Production Assessment Scale (APAS) for use in educational interventions. One hundred videos of up to 90 seconds in length, produced by high school students from Northeast Brazil, were analyzed. The APAS contains twenty statements, grouped into five sections, some of which are based on the Social Cognitive Theory (observational learning; facilitators) and others, such as the halo effect and cognitive comfort, were proposed by Daniel Kahneman. It was found that, of the twenty statements, 15 of them had no significant difference between different evaluators; having obtained a value of 0.941 for Cronbach&amp;#39;s Alpha, showing excellent internal reliability of the APAS. On average, 22 (33.8%) videos received a score greater than 60 points, indicating that they have the potential to significantly contribute to population behavior change in relation to the prevention of mosquito-borne arboviruses; 28 (41.3%) contribute satisfactorily; 15 (22.9%), partially and from one to two videos were scored with values lower than 19 points. Altogether, 12% of the videos received maximum scores in relation to the total score and subjective score. The APAS is, therefore, an example of an effective tool for assessing audiovisual content that can be used in educational interventions in health, with good internal reliability. The scale allows evaluating any content, classifying the production into categories that reveal its potential to promote behavior change.This study was financed in part by the Coordenação de Aperfeiçoamento de Pessoal de Nível Superior – Brasil (CAPES) (Finance Code 001), Universidade Estadual da Paraíba (UEPB), Fundação de Apoio à Pesquisa do Estado da Paraíba (FAPESQ) (Grant 02/2017; 005/2020), British Council Newton Fund Institutional Links (Grant 274560199).Published onlin
