RESUMO
Foot-and-mouth disease (FMD) is an ailment that causes serious damage to the productive chain, and its control through vaccination is of utmost importance for its eradication. Brazil initiated the National Foot-and-Mouth Disease Surveillance Program (PNEFA) with the aim of making the country FMD-free by 2026. As part of the program, notifications of vesicular lesions became mandatory for the Official Veterinary Service (OVS), which is responsible for verifying them. Due to its size, border areas with countries that do not have FMD-free status pose a risk to Brazil and require greater attention. This study described the profile of notifications of suspected outbreaks of vesicular syndrome in Brazil and analyzed the performance of the surveillance system. The results showed 7134 registered notifications of suspected vesicular syndrome outbreaks from 2018 to 2022, with 2022 having the highest number (n = 2343 or 32.85â¯%). The species that generated the most notifications were swine (90.99â¯%), cattle and buffaloes (7.54â¯%), goats and sheep (1.44â¯%), and others (0.03â¯%). The sources of notification were "Veterinary medicine professionals" (61.82â¯%), "Owners or employees" (13.66â¯%), "Third parties" (8.90â¯%), "OVS" (7.20â¯%), and "others" (2.66â¯%). 41.69â¯% of notifications originated from non-border municipalities, and 58.32â¯% from border areas. Only the state of Paraná account for 51.73â¯% of the total notifications. This state also accounted for 66.70â¯% of the 32.47â¯% of notifications with a final diagnosis of "absence of clinically compatible signs or susceptible animals", indicating a certain lack of knowledge in the area, leading to unnecessary notifications and system overload. The performance of the OVS was evaluated based on the service response time from notification registration trough Logistic and Negative binomial regressions. A total of 27.83â¯% of notifications did not meet the Brazilian legally specified time, and the zone related to the state of Parana needs improvements in performance. The presence and peaks of Senecavirus A cases may have influenced an increased number of swine notifications and led to a decrease in OVS response time. The results demonstrate better performance of surveillance in border areas. Given the vast territory of Brazil, it is not expected that 100â¯% of responses occur within the legal timeframe, however, the performance of the surveillance system proved to be adequate, with 86â¯% complied to the legislation. The performance indicators could be used as a monitoring tool, along with indicators to demonstrate system overload. Continued education actions are crucial for strengthening PNEFA.

BACKGROUND: Since 2020 in Mexico, front-of-pack warning labels (FOPWL) have been implemented in processed products. Evidence supports warning labels allow consumers to identify unhealthy products. We aimed to evaluate the hypothetical impact of the FOPWL regulation on the Mexican population's intake of critical nutrients and energy, based on the replacement of food and beverages using 4 hypothetical scenarios which represented the phases of the regulation. METHODS: Dietary data were collected using a standardized 24-h dietary recall from the 2016 Mexican National Health and Nutrition Survey (n = 4184). To evaluate the hypothetical impact of FOPWL, the nutritional content of critical nutrients in processed products was evaluated according to the Mexican Official Standard 051 (NOM-051). Then, we replaced products with several warning labels (WL) with those with a fewer number of them or with non-processed food. For the replacement, 4 hypothetical scenarios were established: scenario 1: the current consumption of the Mexican Population, scenario 2: the replacement during the first phase of the norm, scenario 3: the replacement in the second phase and scenario 4: the replacement in the last phase. We estimated the means, confidence intervals (CI 95%), and the mean percentage change of energy, saturated fat, trans-fat, added sugars, and sodium intake during the second, third, and the fourth scenarios. RESULTS: According to the norm, in the second scenario, the majority of the products presented a label for energy (52.6%) whereas in the third (56.4%) and fourth (61.2%) scenarios were for sodium. In contrast, trans-fat was the least labeled nutrient in all the scenarios (from 2.1 to 4.1%). In the fourth scenario, we observed a reduction of the intake of energy intake to 15.4% as well as saturated fat (- 20%, CI 95% - 18.4; - 21.6), trans-fat (- 8.2%, CI 95% - 6.4; - 10.1) and sodium (- 12.7%, CI 95% - 11.3; - 14.1). The most important reduction was observed for added sugars intake (until - 54.1%, CI 95% - 51; - 57.1). CONCLUSIONS: FOPWL could be an effective strategy to decrease energy consumption and nutrients of concern. If consumers use the FOPWL, it would be an important change in critical nutrients intake. These results support that FOPWL might help the Mexican population to choose healthier nutrition alternatives.

In 2011, the Chilean bovine tuberculosis (bTB) program was launched by the Livestock and Agriculture Service (SAG) as a compulsory countrywide program based on testing and culling of bTB reactors at herd-owners expense. This review outlines the rationale and key components of the bTB program, and the dynamic changes that have occurred since 2011. The paper also examines the problems identified by stakeholders and the initiatives put in place to address the constraints to achieving progress.To date, the program has shown progress in controlling bTB. However, in order to achieve bTB eradication it will be essential to improve the commitment of stakeholders, and to develop a framework of strong and workable regulations that will help to manage bTB outbreaks, particularly where clusters of bTB infection are recorded.
RESUMO
The control of Salmonella in the poultry production chain combined with biosecurity measures is an important tool to maintain and guarantee the sanitary status of Brazilian flocks. The aim of this work was to compare official laboratory data on molecular typification of Salmonella isolates from poultry breeding flocks in different Brazilian states between 2016 and 2018 and identify the production category with the most positive flocks, in light of current legislation. Surveillance data of positive samples from the official Brazilian Salmonella Control Programme sent to Federal Agricultural Defence Laboratory of São Paulo (LFDA-SP) after molecular characterization were analysed. These data were subject to an exploratory study, undergoing a descriptive statistical analysis followed by the use of frequency and non-parametric hypothesis tests. Overall, 49 serovars were detected in poultry broiler-breeder and layer-breeder flocks. Salmonella ser. Heidelberg, Salmonella ser. Anatum, Salmonella ser. Newport, Salmonella ser. Schwarzengrund and Salmonella ser. Mbandaka were the five most common isolated serovars. The data shows that there is an opportunity to improve biosecurity measures in parent breeder flocks. A total of 16 serovars were identified in turkey-breeders. Salmonella ser. Anatum, Salmonella ser. Newport, Salmonella ser. Brandenburg, Salmonella ser. Litchfield, and Salmonella ser. Livingstone were the most common ones. The four official controlled serovars represented a small part of the isolated strains. These data demonstrate the importance of an official program in Brazil for Salmonella surveillance in breeder flocks combined with biosecurity measures.(AU)

Introduction: Although the diurnal fluctuation of motor dysfunction, reversible with small doses of dopamine, is a cornerstone for the phenotype of the autosomal dominant Segawa syndrome, the non-motor symptoms of this neurotransmitter deficiency have still received limited attention. Objective: This study aims to evaluate non-motor symptoms of this dopa-responsive dystonia through an intrafamilial comparative cross-sectional study. Methods: Seventeen individuals with a c.IVS5 + 3insT (c.626 + 3insT) variation in the GTP cyclohydrolase-1 gene (GCH1, HGNC: 4193) and 34 intrafamilial controls were studied using the Beck Depression Inventory-II, the Wiener Matrizen Test 2, the Epworth Sleepiness Scale, the Pittsburgh Sleep Quality Index, the MINI/MINI PLUS Questionnaires, the World Health Organization Quality of Life - BREF Instrument and a drug use assessment questionnaire. Results: No significant difference was found between the groups in the prevalence of sleep disorders and in cognitive function. Nevertheless, generalized anxiety disorder (p = 0.050) and attention-deficit/hyperactivity disorder in childhood (p = 0.011) were observed only in individuals without the molecular variation. The group with the GCH1 variation presented a worse perception about how safe they feel in their daily lives (p = 0.034), less satisfaction with themselves (p = 0.049) and with their relationships (p = 0.029), and a higher prevalence of past major depressive episodes before use of L-Dopa (p = 0.046). Conclusion: Low dopamine could have been protective against generalized anxiety disorder and attention-deficit/hyperactivity disorder in childhood in Segawa group individuals. The prevalence of depression was higher in individuals with the molecular variant prior to the L-Dopa treatment. Considering it, the penetrance estimates for the variant carriers increased from 58.8% to up to 88% in this large studied family. Additionally, neuropsychiatric tests of all individuals with a molecular diagnosis in an affected family are a valuable instrument for its clinical management.
RESUMO
Navicula incerta is a marine microalga distributed in Baja California, México, commonly used in aquaculture nutrition, and has been extended to human food, biomedical, and pharmaceutical industries due to its high biological activity. Therefore, the study aimed to optimize culture conditions to produce antioxidant pigments. A central composite experimental design and response surface methodology (RSM) was employed to analyze the best culture conditions. The medium (nitrogen-deficient concentrations), salinity (PSU = Practical Salinity Unity [g/kg]), age of culture (days), and solvent extraction (ethanol, methanol, and acetone) were the factors used for the experiment. Chlorophyll a (Chl a) and total carotenoids (T-Car), determined spectroscopically, were used as the response variables. The antioxidant capacity was evaluated by DPPH⢠and ABTSâ¢+ radical inhibition, FRAP, and anti-hemolytic activity. According to the overlay plots, the optimum growth conditions for Chl a and T-Car production were the following conditions: medium = 0.44 mol·L-1 of NaNO3, salinity = 40 PSU, age of culture: 3.5 days, and solvent = methanol. The pigment extracts obtained in these optimized conditions had high antioxidant activity in ABTSâ¢+ (86.2-92.1% of inhibition) and anti-hemolytic activity (81.8-96.7% of hemolysis inhibition). Low inhibition (33-35%) was observed in DPPHâ¢. The highest value of FRAP (766.03 ± 16.62 µmol TE/g) was observed in the acetonic extract. The results demonstrated that RSM could obtain an extract with high antioxidant capacity with potential applications in the biomedical and pharmaceutical industry, which encourages the use of natural resources for chemoprevention of chronic-degenerative pathologies.
RESUMO
Infectious laryngotracheitis (ILT), caused by an Alphaherpesvirus (Gallid herpesvirus-1; GaHV-1), has been noticed in the region of the Terras Altas da Mantiqueira, Minas Gerais. From 2010 to 2018, the "Serviço Veterinário Oficial" (SVO) of the "Instituto Mineiro Agropecuário" (IMA), implemented measures to prevent spread of the virus to other regions and control the disease in the area. Due to the close proximity and consequent epidemiological link among farms, the region was considered a unique epidemiological unit. To check the efficiency of the ILT control measures, we carried out: (1) a seroepidemiological survey, (2) questionnaires for evaluating biosecurity measures; and (3) an evaluation of the influence of farm population density on the occurrence of ILT. In 2016, 2017, and 2018, ILT was investigated using epidemiological and clinicopathological methods, along with GaHV-1 molecular detection. Serological survey was carried out on 24 farms in the quarantined region and on 13 farms from other regions of the state. In 2010 and 2018, questionnaires were applied to collect data and determine indicators of biosecurity practices in all farms of the quarantined area. The differences were then assessed (Wilcoxon's p<0.05). The results indicated positive serology throughout the region, although only on four farms (16.6%) the chickens have clinical signs, macroscopic and histological lesions of ILT. The prevalence of viral infection increased from 2016 (27%) to 2017 (50%) and was higher in farms with a high stock density (p=0.033). No disease, virus or antibodies were detected in the farms outside of the quarantined area. Although the biosecurity indicators had improved on all farms in the quarantined area (p<0.05), the virus was active and circulating in the region. The contingency measures have contained the outbreak, but biosecurity practices are paramount in the control of new outbreaks. Official control will be maintained in the region, including surveillance of new cases and biosecurity procedures to mitigate the risk of the virus reaching other regions.(AU)

Em 2016, 2017 e 2018, a LTI foi investigada usando métodos epidemiológicos e clínico-patológicos, com a detecção molecular de GaHV-1. O levantamento sorológico foi realizado em 24 granjas da região interditada e em 13 granjas de outras regiões do estado. Em 2010 e 2018, foram aplicados questionários para coletar dados e determinar indicadores de medidas de biosseguridade em todas as granjas da área interditada. As diferenças foram avaliadas (p<0,05 de Wilcoxon). Os resultados indicaram sorologia positiva em toda a região, embora apenas em quatro granjas (16,6%) as galinhas apresentaram sinais clínicos, lesões macroscópicas e histológicas da LTI. A prevalência de infecção viral aumentou de 2016 (27%) para 2017 (50%) e foi maior em fazendas com alta densidade de alojamento (p=0,033). Presença da doença, vírus ou anticorpos foram detectados nas granjas fora da área interditada. Embora os indicadores de biosseguridade tenham melhorado em todas as fazendas da área interditada (p<0,05), o vírus está ativo e circulava na região. As medidas de contingência contiveram o surto, mas as práticas de biosseguridade são fundamentais para o controle de novos surtos. O controle oficial será mantido na região, incluindo a vigilância de novos casos e procedimentos de biosseguridade para mitigar o risco de transmissão do vírus para outras regiões.(AU)

Vegetables are one of the most important components in the human diet, but despite their multiple nutritional components, studies have demonstrated the presence of trace metals in their edible parts. In Ecuador, two of the most consumed crops are tomato (Solanum lycopersicum) and lettuce (Lactuca sativa). The importance of these two crops in the Ecuadorian diet, especially in large and touristic locations like the Metropolitan District of Quito, implies food safety-related concerns for locals and visitors. However, no previous studies have quantified the cadmium and lead levels in these two vegetables using samples from Quito markets. Thus, the aim of this study was to determine the cadmium and lead content in both tomato and lettuce products from main nonorganic and organic markets in Quito using a graphite furnace atomic absorption spectrophotometer. The results showed that the cadmium levels were lower than 0.058 in tomatoes and 0.034 mg/kg in lettuce, which are under the respective threshold values (0.100 and 0.200 mg/kg). Regarding lead, levels lower than 0.066 mg/kg were detected in lettuce, which did not exceed the CXS 193-1995 threshold value, while levels in tomatoes were near or exceeded the threshold value (0.100 mg/kg) from four markets (0.209, 0.162, 0.110, 0.099 mg/kg), suggesting a possible risk from tomato consumption. In addition, most vegetables marketed as organic had higher metal content than those coming from nonorganic markets. Based on these results, local health and commercial control authorities should monitor contaminants in food products sold in Quito and other places in Ecuador to ensure their safety.
RESUMO
According to the World Organisation for Animal Health (OIE), zoning is a risk management strategy for achieving the progressive control and eradication of animal diseases, and for providing guarantees for international trade. The implementation and effectiveness of zoning relies on the quality of Veterinary Services. Eradicating a disease and securing trading partners' recognition of this disease-free status demands resources, and promotes economic and fruitful development. It also guarantees the sanitary safety of trade, provided that OIE standards are applied and the World Trade Organization (WTO) Agreement on the Application of Sanitary and Phytosanitary Measures (SPS Agreement) is complied with. The OIE international standards and the SPS Agreement lay down provisions for the effective implementation of zoning and the recognition of disease-free zones. Although animal-disease-free statuses place such zones in a favourable position with regard to exporting their products to the international market, they can create internal restrictions between regions of the same country with differing statuses. As a general rule, each importing country implements its own evaluation procedure, independent of OIE official recognition. While this usually provides for information evaluation and an on-site inspection mission, there is no harmonisation between countries regarding the methodology or the information required for risk assessment. Recognition of a disease-free zone does not imply automatic permission to export any product from that zone. Firstly, it is necessary to request that the market be opened for each product in question, guaranteeing the conditions demanded by the target market (risk analysis and animal health certification). To benefit from external markets, there are ways of speeding up bilateral recognition of disease-free zones, such as bilateral veterinary agreements or free trade agreements that establish clear areas and procedures to be implemented by trading partner countries. The ongoing exchange of information among countries builds trust among their Veterinary Services and authorities, which leads to expedited recognition procedures. The work of the OIE (Pathway for the Evaluation of Performance of Veterinary Services [PVS Pathway], OIE Observatory) and the WTO Committee on Sanitary and Phytosanitary Measures (SPS Committee) (enforcement mechanisms) should be strengthened to assist countries in implementing zoning.
D'après l'Organisation mondiale de la santé animale (OIE), le « zonage ¼ est une stratégie de gestion du risque permettant d'avancer sur la voie du contrôle progressif des maladies animales et de leur éradication tout en fournissant des garanties dans le cadre des échanges internationaux. Sa mise en oeuvre et son efficacité sont tributaires de la qualité des Services vétérinaires. Si l'éradication réussie d'une maladie et la reconnaissance du statut indemne par les partenaires commerciaux mobilisent des ressources, elles constituent également une incitation majeure au développement productif et économique. En outre, elles garantissent la sécurité sanitaire des échanges internationaux, à condition d'appliquer les normes de l'OIE et de respecter les dispositions de l'Accord sur l'application des sanitaires et phytosanitaires (Accord SPS) de l'Organisation mondiale du commerce (OMC). L'OIE et l'Accord SPS établissent des dispositions pour la mise en oeuvre effective du « zonage ¼ et la reconnaissance des zones indemnes de maladies. Ce statut sanitaire place les zones qui en bénéficient en position favorable pour exporter leurs produits vers les marchés internationaux, mais il peut aussi entraîner des restrictions au niveau national par rapport aux zones du pays dotées d'un statut différent. Il est d'usage que chaque pays applique ses propres procédures indépendamment de la reconnaissance par l'OIE. Cela passe généralement par une évaluation de l'information fournie et par une mission d'inspection in situ, mais ni la méthodologie ni les informations requises pour mener à bien l'évaluation du risque n'ont fait l'objet d'une harmonisation de la part des pays. La reconnaissance d'une zone indemne ne vaut pas autorisation automatique d'exporter tout produit à partir de cette zone, car il faut encore, pour chaque produit, solliciter l'ouverture du marché et présenter des garanties démontrant que les conditions imposées par le marché de destination sont satisfaites (analyse du risque et certification sanitaire). Des méthodes existent pour bénéficier des marchés extérieurs en accélérant les reconnaissances bilatérales des zones indemnes de maladies ; il s'agit notamment des accords vétérinaires bilatéraux ou des accords de libre-échange, qui définissent clairement les cadres d'application et les procédures à mettre en place par les pays partenaires commerciaux. L'échange permanent d'informations entre les pays partenaires favorise la confiance entre leurs Services et Autorités vétérinaires respectifs, ce qui facilite d'autant ces procédures. Il convient de renforcer les travaux de l'OIE (Processus d'évaluation des performances des Services vétérinaires [Processus PVS], Observatoire des normes de l'OMC) et du Comité SPS de l'OMC (mécanismes d'évaluation de la conformité) afin d'aider les pays à mettre en oeuvre le « zonage ¼.
Según la Organización Mundial de Sanidad Animal (OIE), la «zonificación¼ es una estrategia de gestión del riesgo para avanzar en el control progresivo y la erradicación de enfermedades animales y para dar garantías al comercio internacional. Su implementación y eficacia dependen de la calidad de los Servicios Veterinarios. Erradicar una enfermedad y lograr el reconocimiento de tal situación por parte de socios comerciales implica recursos e incentiva el desarrollo productivo y económico. También garantiza la seguridad sanitaria del comercio siempre que se apliquen las normas de la OIE y se respete el Acuerdo sobre la Aplicación de Medidas Sanitarias y Fitosanitarias de la Organización Mundial del Comercio (OMC) (Acuerdo MSF). Las normas internacionales de la OIE y el Acuerdo MSF establecen disposiciones para una implementación efectiva de la «zonificación¼ y el reconocimiento de zonas libres de enfermedades. Este estatus sanitario posiciona favorablemente a dichas zonas para exportar sus productos al mercado internacional, pero puede generar restricciones internas respecto a regiones del mismo país con estatus diferentes. Lo habitual es que cada país aplique un proceso propio, independientemente del reconocimiento de la OIE. En general, contemplan una evaluación de la información y una misión de inspección in situ, pero no existe una armonización entre países ni respecto a la metodología ni respecto a la información requerida para la evaluación de riesgos. Este reconocimiento no implica el permiso automático para exportar cualquier producto desde esa zona, sino que se debe solicitar la apertura del mercado para cada producto en cuestión garantizando las condiciones exigidas por el mercado de destino (análisis del riesgo y certificación sanitaria). Para beneficiarse de los mercados externos, existen formas de agilizar los reconocimientos bilaterales de las zonas libres de enfermedades, como los acuerdos bilaterales veterinarios o los Acuerdos de Libre Comercio, mediante los cuales se establecen ámbitos y procedimientos claros a implementar por parte de los países socios comerciales. El intercambio de información permanente entre los países genera confianza entre sus Servicios y Autoridades Veterinarias, lo cual redunda en la agilización de estos procesos. Se debe reforzar el trabajo de la OIE (Proceso de Prestaciones de los Servicios Veterinarios [Proceso PVS], Observatorio de la OIE) y del Comité MSF de la OMC (mecanismos de observancia) para ayudar a los países a implementar la «zonificación¼.

Although Northeast Brazil is considered free of foot and mouth disease (FMD) with vaccination, several economic and health damages are still recorded due to the occurrence of vesicular syndromes that can be evaluated, such as Vesicular Stomatitis (VS). Therefore, this study aimed to confirm the occurrence of this disease and to determine the predominant viral serotype in suspected cases notified to the Official Veterinary Service of Ceará in 2013 performing official diagnostic protocols recommended by the World Organization for Animal Health. After clinical and epidemiological investigation in 46 farms, 32 probable cases of VS were considered with 78 sampled animals, 65 bovines and 13 equines. Serum (54) and epithelium (24) samples were collected. Six (14.6%) of 41 bovines and 8 (61.5%) of 13 equines described seroconversion to Indiana Vesiculovirus (IVV) by viral neutralization. The IVV was detected in 15 (62.5%) of 24 bovines epithelia using the indirect sandwich ELISA. Finally, positive epithelium underwent complement fixation test viral subtyping that identified the occurrence of Indiana III serotype (Alagoas/IVV-3) in 11 (73.3%) of 15 previous positives cattle. These were the first confirmed cases of VS in Ceará with an official diagnosis of IVV-3, confirming the endemic character attributed to the state through previous unofficial serological surveys. The presence of VS is a continuing diagnostic challenge, given the risk of possible incursions of FMD. Vesicular stomatitis is recurrent and is a worrying in this area free of foot and mouth disease with vaccination that bring damage to producers and a maximum alert to the Sanitary Defense Organs in the face of a probable case of vesicular syndrome.(AU)
Embora o Nordeste do Brasil seja considerado livre de Febre Aftosa (FA) com a vacinacao, ainda sao registrados varios prejuízos econômicos e sanitários devido a ocorrencia de sindromes vesiculares que precisam ser adequadamente avaliadas, como Estomatite Vesicular (EV). Portanto, este estudo teve como objetivo confirmar a ocorrencia desta doenca e determinar o sorotipo viral predominante em casos suspeitos notificados ao Servico Veterinario Oficial do Ceara no ano de 2013 realizando protocolos oficiais de diagnóstico recomendados pela Organizacao Mundial de Saude Animal. Após investigação clínica e epidemiológica em 46 propriedades rurais, foram considerados 32 casos prováveis de propriedade foco de EV com 78 animais amostrados, sendo 65 bovinos e 13 equídeos. Amostras de soro (54) e epitelio (24) foram coletadas. Analises sorologicas de 6 (14,6%) de 41 bovinos e 8 (61,5%) de 13 equídeos apresentaram soroconversao ao Vesiculovirus Indiana (VVI) por neutralizacao viral. O VVI foi detectado em 15 (62,5%) de 24 epitélios bovinos usando ELISA indireto sanduiche. Por fim, amostras de epitélio positivas foram submetidas a subtipagem viral por fixacao do complemento que identificou a ocorrência do sorotipo Indiana III (Alagoas/VVI-3) em 11 (73,3%) de bovinos. Estes foram os primeiros casos confirmados de EV no estado do Ceara com diagnostico oficial de VVI-3 confirmando o carater endemico atribuido ao Estado por meio de levantamentos sorologicos nao oficiais anteriores. A presença de EV é um desafio diagnóstico contínuo, dado o risco de possíveis incursões de FA. A Estomatite Vesicular é recorrente e preocupante nesta área livre de FA com vacinação pois, além de prejuízos aos produtores, traz um alerta máximo aos Órgãos de Defesa Sanitária diante de um caso provável de síndrome vesicular.(AU)

This study aimed to evaluate the effectiveness of a school-based mental health education program in preventing adolescent suicide attempts in an impoverished urban area in Peru, as part of an Official Development Assistance project by the Korea International Cooperation Agency. The PRECEDE-PROCEED model informed the effectiveness study. In this intervention, the participants were first to fifth grade students in public secondary schools. The pre-post intervention survey was conducted with a stratified random sampling method. A sample of 768 and 738 students in experimental and control groups was analyzed comparatively, using chi-squared tests and logistic regression. This study found that the program had a positive effect on adolescent mental health-related risk behaviors and suicide attempts in the experimental group compared to the control group. Thus, the intervention may have helped prevent the increase in mental health-related risk behaviors and suicide attempts. Further, parental affection, when included in the intervention, had a significant effect on suicide attempts. As such, the involvement of parental affection in the intervention might be effective in preventing suicide attempts. To enhance the effectiveness of interventions aiming to prevent adolescent suicide, the participation and attention of parents, as well as adolescents, must be encouraged. Further, to maintain the effectiveness of the intervention and expand coverage to other schools in the neighborhood, a strategy for project sustainability is needed, particularly with regards to capacity-building in schools and communities.

RESUMO
La crisis iniciada en Venezuela a mediados de 1983 provocó un manifiesto deterioro en la cantidad y calidad del consumo de alimentos por parte de los sectores de mas bajos recursos. Los porcentajes de adecuación más bajos respecto a los Requerimientos de Energía y Nutrientes de la Población Venezolana corresponden a hierro, vitamina A y en menor grado a vitaminas del complejo B. El Instituto Nacional de Nutrición inició en 1990 la factibilidad de enriquecer la harina de maíz precocida, HMP, responsable por un 40 % de las Calorías derivadas de los cereales y de un 15 - 16 % del total de calorías de la dieta, con hierro (fumarato ferroso), vitamina A, tiamina, riboflavina y niacina. En 1992 se propuso un perfil de enriquecimiento requerido para que 50 g de HMP cubriese un 25 % de los requerimientos de estos nutrientes, ya tomados en cuenta las pérdidas durante la preparación de la arepa. El conocimiento de esta medida como política oficial, causó cierta molestia en el sector privado. En Agosto 1992, por Decreto Presidencial No 2.492 se crea la Comisión para el Enriquecimiento Nutricional de los Alimentos, CENA, con el específico propósito del enriquecimiento de la HMP. Con los esfuerzos coordinados del sector oficial y de la industria privada, se pudo llegar a un consenso sobre el perfil de enriquecimiento de la HMP, el cual fue anunciado por la CENA. (por kg): vitamina A: 2.700 ER; tiamina: 3,1 mg; riboflavina: 2,5 mg; niacina: 51 mg; hierro: 50 mg. Comisión Venezolana de Normas Industriales. COVENIN. Harina de maíz precocida. (3 era. Revisión) 2135:1996. Obligatorio cumplimento. Desde febrero 1993 toda la HMP comercializada en Venezuela debe estar enriquecida. Harina de trigo. HT. En noviembre 1992, la Asociación Venezolana de Productores de Trigo, AVPT, presentó un proyecto no obligatorio de fortificación. En Marzo la CENA rechazó el carácter no obligatorio y de acuerdo con la AVPT se acordó un perfil de enriquecimiento para la HT: (por kg): tiamina: 1,5 mg; riboflavina: 2,0 mg; niacina: 20 mg; hierro: 20 mg (como fumarato ferroso). Comisión Venezolana de Normas Industriales. COVENIN. Harina de trigo (4 ta. Revisión) 217: 2001. Obligatorio cumplimiento. Desde agosto 1993 toda la HT comercializada en Venezuela debe estar enriquecida(AU)
TIn Venezuela a severe economic crisis beginning in 1983 provoked a progressive reduction of the quality and quantity of food consumed by the low socioecnomic strata of the population. The lowest adequacy percentages with respect to Venezuelan RDAs were for iron, vitamin A and to a lesser extent, for vitamin B complex. Being precooked corn flour, PCF, responsible for 40 % of the Calories derived from cereals and for 15 -16 % of the total calories intake in the diet, an excellent and unique vehicle for enrichment, the National Institute of Nutrition, NIN, started the investigations toward its fortification with iron (as ferrous fumarate), vitamin A, thiamin, riboflavin and niacin. In 1992 a fortification profile was developed in such a way that 50 g of PCF (amount needed for a 110 g ready-to-eat arepa) covered approximately 25 % of the RDAs for the mentioned nutrients, after taking into consideration the losses due to the cooking process. The announcement of this measure as an official policy, provoked some adverse reactions among the private sector. In August 1992, by Presidential Decree No 2.492, the Commission for the Nutritional Enrichment of Foods, CENA, was created with the specific task of reconciling efforts and carry forward the enrichment of the PCF. With the attendance of key representatives of the corn and wheat industries, the government and the media, the CENA announced the official fortification profile of the PCF (per kg) : vitamin A: 2,700 RE; thiamin: 3.1 mg; riboflavin: 2.5 mg; niacin: 51 mg; iron: 50 mg. Official Venezuelan Bureau of Standars (COVENIN), mandatory Standard No 2135-1996. Since February 1993 all the PCF sold in Venezuela must be enriched. Wheat flour. WF. The Venezuelan Wheat Producers Association, VWPA, presented in november 1992 a tentative and non compulsory fortification profile. In march the CENA voted against the non compulsory character of the fortification of WF and upon agreement with the VWPA, set in force the mandatory fortification profile as follow (per kg): thiamin: 1.5 mg; riboflavin: 2.0 mg; niacin: 20 mg; iron: 20 mg (as ferrous fumarate). COVENIN mandatory Standard No 217:2001. Since august 1993 all the WF sold in Venezuela must be enriched(AU)

The detection of pesticide residues in leafy vegetables has been a relevant concern in Chile over the last years. There is also a priority at the national level to propose a methodology to assess health risks. The aim of this study was to evaluate the presence of pesticide residues in ready-to-eat leafy vegetables in order to evaluate different models for health risk assessment. The models considered data of the World Health Organization (WHO) and the Ministry of Health of Chile (MINSAL). The Hazard Quotients and Hazard Indexes for the pesticides evaluated in all models decreased in the following order: methamidophos>lambda-cyhalothrin> chlorpyrifos. From a food safety perspective, the investigated samples suggest the presence of a greater health risk to consumers when compared using the official data of MINSAL, which needs appropriate attention.

A Instrução Normativa nº 46, de 28 de agosto de 2018, regulamenta a exportação de bovinos, bubalinos, ovinos e caprinos vivos destinados ao abate imediato, engorda ou reprodução e estabelece normas e procedimentos básicos para a preparação de animais vivos para exportação por via marítima, fluvial, aérea ou terrestre. Neste artigo, abordam-se seus principais tópicos em relação ao bem-estar dos animais. Visto o aumento desta atividade nos últimos anos no Brasil, a nova legislação representa um avanço na área de transporte de animais vivos, pois até então a legislação era ausente. Contudo, esta é uma atividade complexa e que envolve uma das etapas mais estressantes aos animais de produção, o manejo pré-abate. Mesmo com este avanço, devemos atentar aos pontos ainda deficientes e que poderão ser melhorados nos próximos anos, eliminando ou minimizando falhas que ainda persistem, embasados em estudos técnicos e científicos.
Normative Instruction No. 46 from August 28, 2018, which regulates the exportation of cattle, buffalos, sheep and goats for immediate slaughter, fattening or reproduction, establishes the norms and procedures for the preparation of live animals for exportation by sea, river, air or land. In this article, we discuss the main topics related to animal well-being within this context. Considering the increase of this activity in recent years in Brazil, the new legislation represents an improvement in the area of transportation of live animals, given that until then there was no legislation. However, this is a complex activity that involves one of the most stressful stages for animals, the pre-slaughter management. Even with this improvement, we must take into account the areas that are still deficient and that can be improved in the coming years, eliminating and/or minimizing failures that still persist, based on technical and scientific studies.
