RESUMO

This Analysis presents a recently developed food system indicator framework and holistic monitoring architecture to track food system transformation towards global development, health and sustainability goals. Five themes are considered: (1) diets, nutrition and health; (2) environment, natural resources and production; (3) livelihoods, poverty and equity; (4) governance; and (5) resilience. Each theme is divided into three to five indicator domains, and indicators were selected to reflect each domain through a consultative process. In total, 50 indicators were selected, with at least one indicator available for every domain. Harmonized data of these 50 indicators provide a baseline assessment of the world's food systems. We show that every country can claim positive outcomes in some parts of food systems, but none are among the highest ranked across all domains. Furthermore, some indicators are independent of national income, and each highlights a specific aspiration for healthy, sustainable and just food systems. The Food Systems Countdown Initiative will track food systems annually to 2030, amending the framework as new indicators or better data emerge.

RESUMO

Managing investments in dairy cow health at a national and global scale, requires an improved understanding of current on-farm expenses for cow health (e.g., expenditure for medicine and veterinary consultations). The aim of this study was to assess on-farm health investments for typical dairy farms in 15 case study countries, including Argentina, Australia, Bangladesh, Brazil, Canada, India, China, Colombia, Indonesia, Kenya, New Zealand, Uganda, UK, Uruguay, and USA. The study was conducted using a descriptive analysis of a secondary data set that was obtained from the International Farm Comparison Network (IFCN). The results suggest that health expenditures take up a relatively small proportion (<10%) of the annual total production costs per cow across all countries in the sample. The means of production costs (e.g., feed, machinery) can take up to 90% of the total production costs for highly intensive systems, while these costs can be as low as 9% for extensive systems. This study highlights the importance of understanding on-farm animal health investments as a contribution to improved national and global decision making about animal health in the dairy sector.

RESUMO

Hantavirus pulmonary syndrome (HPS) is a zoonotic emerging infectious disease caused by New World orthohantaviruses (family Hantaviridae) hosted by rodents of the family Cricetidae. In Argentina, one of its main hosts is the sigmodontine rodent Oligoryzomys flavescens, a widely distributed mouse of the Pampas, Delta and Espinal ecoregions of central-east Argentina. Because the abundance of the reservoir and its proportion in the rodent community affects both virus prevalence and human exposure risk, its estimation throughout its known geographical distribution is of key importance for the design of public health strategies to prevent HPS. The aim of this study was therefore to model the relative abundance of O. flavescens in most of the Pampas ecoregion within Buenos Aires Province, Argentina, where hantavirus pulmonary syndrome is endemic. To do this we used owl-pellet samples collected between 2006 and 2008 from 51 sites distributed throughout most of Buenos Aires province. Mammalian prey in each pellet was identified to the lowest possible taxonomic level by examination of the skulls, dentaries and molars. We modelled the frequency of O. flavescens found in each sample as a function of climatic, environmental, and topographic data of each site. The two best models were applied to a Geo referential Information System to build maps of estimated frequency (as a proxy of relative abundance) within Buenos Aires province. Estimated relative abundance of O. flavescens in Buenos Aires province was significantly associated with annual mean temperature, annual precipitation and presence of freshwater bodies, and varied among sub-regions, with the Inland and Rolling Pampas being the regions with highest frequencies. Knowing in which areas O. flavescens abundance is expected to be higher can be used to concentrate limited sanitary efforts in those areas that are most needed in order to reduce transmission and increase detection.

RESUMO

Introduction: Oral cavity cancer (OCC) is one of the 10 most common types of tumors in the world. Surgical resection is the most indicated initial treatment, followed by adjuvant therapy, depending on tumor stage. A few studies have suggested that patients treated in high-volume hospitals present better oncologic outcomes; however, particularly in continental countries, some patients are treated in regional hospitals. Objective: To evaluate the results of OCC patients treated in low-volume regional hospitals. Methods: This is a retrospective longitudinal study conducted with patients diagnosed with OCC and operated on in a low-volume hospital between January 2003 and December 2018. Results: 174 patients with OCC were treated at the institution - an average of 11 patients/year. The most common tumor location was the tongue (48.2%), followed by the lip (18.2%). Squamous cell carcinomas were the most frequent (94.7% of patients). Adjuvant radiotherapy and chemotherapy were performed in 46.7 and 31.9% of patients, respectively. Almost 21% of patients had some postoperative complication. Specific survival of 62.6% and global survival of 58.2% after 3 years were similar to the results reported in high-volume centers. Disease-free survival was 45.8% in the same period. Conclusion: Low-volume hospitals qualified for oncological treatments can present outcomes similar to those of high-volume centers, and are thus a regional option for patients with OCC.

RESUMO

Diets link human health with environmental sustainability, offering promising pressure points to enhance the sustainability of food systems. We investigated the health, environmental, and economic dimensions of the current diet in Argentina and the possible effects of six dietary change scenarios on nutrient adequacy, dietary quality, food expenditure, and six environmental impact categories (i.e., GHG emissions, total land occupation, cropland use, fossil energy use, freshwater consumption, and the emission of eutrophying pollutants). Current dietary patterns are unhealthy, unsustainable, and relatively expensive, and all things being equal, an increase in income levels would not alter the health dimension, but increase environmental impacts by 33-38%, and costs by 38%. Compared to the prevailing diet, the six healthier diet alternatives could improve health with an expenditure between + 27% (National Dietary Guidelines) to -5% (vegan diet) of the current diet. These dietary changes could result in trade-offs between different environmental impacts. Plant-based diets showed the lowest overall environmental impact, with GHG emissions and land occupation reduced by up to 79% and 88%, respectively, without significant changes in cropland demand. However, fossil energy use and freshwater consumption could increase by up to 101% and 220%, respectively. The emission of eutrophying pollutants could increase by up to 54% for all healthy diet scenarios, except for the vegan one (18% decrease). We conclude that the health and environmental crisis that Argentina (and other developing countries) currently face could be mitigated by adopting healthy diets (particularly plant-based), bringing in the process benefits to both people and nature.

RESUMO

Agriculture is the largest single source of global anthropogenic methane (CH4) emissions, with ruminants the dominant contributor. Livestock CH4 emissions are projected to grow another 30% by 2050 under current policies, yet few countries have set targets or are implementing policies to reduce emissions in absolute terms. The reason for this limited ambition may be linked not only to the underpinning role of livestock for nutrition and livelihoods in many countries but also diverging perspectives on the importance of mitigating these emissions, given the short atmospheric lifetime of CH4. Here, we show that in mitigation pathways that limit warming to 1.5°C, which include cost-effective reductions from all emission sources, the contribution of future livestock CH4 emissions to global warming in 2050 is about one-third of that from future net carbon dioxide emissions. Future livestock CH4 emissions, therefore, significantly constrain the remaining carbon budget and the ability to meet stringent temperature limits. We review options to address livestock CH4 emissions through more efficient production, technological advances and demand-side changes, and their interactions with land-based carbon sequestration. We conclude that bringing livestock into mainstream mitigation policies, while recognizing their unique social, cultural and economic roles, would make an important contribution towards reaching the temperature goal of the Paris Agreement and is vital for a limit of 1.5°C. This article is part of a discussion meeting issue 'Rising methane: is warming feeding warming? (part 1)'.

RESUMO

Dietary transitions, such as eliminating meat consumption, have been proposed as one way to reduce the climate impact of the global and regional food systems. However, it should be ensured that replacement diets are indeed nutritious and that climate benefits are accurately accounted for. This study uses New Zealand food consumption as a case study for exploring the cumulative climate impact of adopting the national dietary guidelines and the substitution of meat from hypothetical diets. The new GWP* metric is used as it was designed to better reflect the climate impacts of the release of methane than the de facto standard 100-year Global Warming Potential metric (GWP100). A transition at age 25 to the hypothetical dietary guideline diet reduces cumulative warming associated with diet by 7 to 9% at the 100th year compared with consuming the average New Zealand diet. The reduction in diet-related cumulative warming from the transition to a hypothetical meat-substituted diet varied between 12 and 15%. This is equivalent to reducing an average individual's lifetime warming contribution by 2 to 4%. General improvements are achieved for nutrient intakes by adopting the dietary guidelines compared with the average New Zealand diet; however, the substitution of meat items results in characteristic nutrient differences, and these differences must be considered alongside changes in emission profiles.

RESUMO

PURPOSE: There are no randomized trials comparing the incidence or severity of facial nerve dysfunction after superficial parotidectomy with or without continuous intraoperative electromyographic neuromonitoring. This pilot study aimed to assess the variability in outcomes to help determine the needs and possible ethical issues in a full-scale study. METHODS: Prospective randomized pilot study comparing the incidence and grade of facial nerve dysfunction among 106 patients subjected to superficial parotidectomy with or without continuous four channels electromyographic neuromonitoring (52 monitored patients and 54 controls). RESULTS: The incidences of immediate (38.3% vs. 51.8%, p = 0.1) and late facial dysfunction, up to 180 days following surgery, (3.8% vs. 5.5%, p = 0.4) were similar between monitored patients and controls. Immediate facial nerve dysfunction with a House-Brackmann ≥ grade III was more frequent among the non-monitored patients (57.8% vs. 30%, p = 0.2), and outcomes were significantly poorer in this group (mean sum score of 68.7 vs. 81.5, p = 0.002), when assessed with the regional Sunnybrook scale. A full-scale prospective randomized study to detect a significant reduction in the incidence of immediate facial nerve dysfunction with the use of continuous intraoperative electromyographic neuromonitoring, with 80% power and a 5% significant level, would require 560 patients allocated to the monitored and control groups. Considering a mean rate of 30 patients/year/center, such a study would require the participation of five centers for 4 years. CONCLUSIONS: In the present pilot study, the incidences of immediate and late facial nerve dysfunction were similar between patients with benign parotid tumors subjected to superficial parotidectomy with or without continuous intraoperative electromyographic neuromonitoring. However, immediate facial dysfunction was more severe among the non-monitored patients.

RESUMO

Transposable elements (TEs) are repetitive nucleotide sequences that make up a large portion of eukaryotic genomes. They can move and duplicate within a genome, increasing genome size and contributing to genetic diversity within and across species. Accurate identification and classification of TEs present in a genome is an important step towards understanding their effects on genes and their role in genome evolution. We introduce TE-Learner, a framework based on machine learning that automatically identifies TEs in a given genome and assigns a classification to them. We present an implementation of our framework towards LTR retrotransposons, a particular type of TEs characterized by having long terminal repeats (LTRs) at their boundaries. We evaluate the predictive performance of our framework on the well-annotated genomes of Drosophila melanogaster and Arabidopsis thaliana and we compare our results for three LTR retrotransposon superfamilies with the results of three widely used methods for TE identification or classification: RepeatMasker, Censor and LtrDigest. In contrast to these methods, TE-Learner is the first to incorporate machine learning techniques, outperforming these methods in terms of predictive performance, while able to learn models and make predictions efficiently. Moreover, we show that our method was able to identify TEs that none of the above method could find, and we investigated TE-Learner's predictions which did not correspond to an official annotation. It turns out that many of these predictions are in fact strongly homologous to a known TE.

RESUMO

Profile hidden Markov models (pHMMs) have been used to search for transposable elements (TEs) in genomes. For the learning of pHMMs aimed to search for TEs of the retrotransposon class, the conventional protocol is to use the whole internal nucleotide portions of these elements as representative sequences. To further explore the potential of pHMMs in such a search, we propose five alternative ways to obtain the sets of representative sequences of TEs other than the conventional protocol. In this study, we are interested in Bel-PAO, Copia, Gypsy, and DIRS superfamilies from the retrotransposon class. We compared the pHMMs of all six protocols. The test results show that, for each TE superfamily, the pHMMs of at least two of the proposed protocols performed better than the conventional one and that the number of correct predictions provided by the latter can be improved by considering together the results of one or more of the alternative protocols.

RESUMO

BACKGROUND: There are a growing number of thyroid ultrasound courses to train endocrinologists, pathologists, and surgeons to perform ultrasound-guided fine-needle aspiration (FNA). However, there are limited data to support the efficacy of ultrasound-guided FNA performed by nonradiologists. METHODS: We compared the efficacy of ultrasound-guided FNA performed by surgeons newly trained in thyroid ultrasound with that of the same technique performed by 1 experienced radiologist. The ratio of nondiagnostic examinations was used to compare the 2 groups. RESULTS: A total of 197 ultrasound-guided FNAs were performed on 172 women (95.53%) and 8 men (4.47%) over a 12-month period. The efficacy of ultrasound-guided FNA did not differ between groups. A nondiagnostic report was found in 23% and 25.7% of the examinations performed by the radiologist and surgeons, respectively. CONCLUSION: The efficacy of ultrasound-guided FNAs performed by our 2 surgeons was similar to that of our radiologist. © 2016 Wiley Periodicals, Inc. Head Neck 39: 439-442, 2017.

RESUMO

ABSTRACT INTRODUCTION: Most patients with laryngeal carcinoma present tumors in the glottis that can be treated by different treatment modalities. Some authors consider open partial laryngectomy as obsolete, while others still deem this as a viable and cost-efficient option. OBJECTIVES: To compare the oncological and functional results of a series of patients undergoing partial laryngectomy vs. external radiotherapy for the treatment of glottic cancer. METHODS: Historical cohort study with a series of glottic carcinoma patients undergoing partial laryngectomy or external radiotherapy during a period of ten years. RESULTS: Sixty-two patients with glottic carcinoma were included. Group A comprised those submitted to partial laryngectomy (n = 30), and Group B, those who underwent radiotherapy (n = 32). They were homogeneous in the comparison of mean age, 56.4 vs. 60.4 years (p = 0.12) and distribution in pathological stage (p = 0.91). With regard to oncological outcome, there were no differences in distant metastasis rates, or second primary tumor between groups (p = 1.0), as well as in disease-free time, laryngeal rescue-free time, and overall five-year survival. Severe complication rates were also similar between groups. CONCLUSION: Open partial laryngectomy had complication rates and oncological results similar to those of radiotherapy for patients with glottic carcinomas and should still be considered among the main available therapeutic options.


Resumo Introdução: A maioria dos pacientes com carcinoma de laringe apresentam tumores na região glótica suscetíveis a diferentes modalidades de tratamento. Alguns autores consideram a laringectomia parcial aberta em desuso enquanto outros ainda a indicam como uma opção viável e custo eficiente. Objetivos: Comparar os resultados oncológicos e funcionais de uma série de pacientes submetidos à laringectomia parcial versus radioterapia externa para o tratamento do câncer glótico. Método: Estudo tipo coorte histórica com uma série de pacientes com carcinoma glótico submetidos à laringectomia parcial ou radioterapia externa em período de 10 anos. Resultados: Foram incluídos 62 pacientes com carcinoma glótico distribuídos em Grupo A: submetido à laringectomia parcial (n = 30) e Grupo B submetido a radioterapia (n = 32) que se mostraram homogêneos na comparação de média de idade de 56,4 vs. 60,4 (p = 0,12) e distribuição em estadios patológicos (p = 0,91). Com relação ao desfecho oncológico, não foram observadas diferenças nas taxas de metástase à distancia, ou segundo primário entre os grupos (p = 1,0) assim como no tempo livre de doença, tempo livre de resgate laríngeo e sobrevida geral em 5 anos. As taxas de complicações severas também foram semelhantes entre os grupos. Conclusão: A laringectomia parcial aberta apresentou taxas de complicações e resultados oncológicos semelhante àqueles do tratamento radioterápico para pacientes com carcinomas glóticos e ainda deve ser considera entre as principais opções terapêuticas disponíveis.

RESUMO

Profile hidden Markov models (profile HMMs) are known to efficiently predict whether an amino acid (AA) sequence belongs to a specific protein family. Profile HMMs can also be used to search for protein domains in genome sequences. In this case, HMMs are typically learned from AA sequences and then used to search on the six-frame translation of nucleotide (NT) sequences. However, this approach demands additional processing of the original data and search results. Here, we propose an alternative and more direct method which converts an AA alignment into an NT one, after which an NT-based HMM is trained to be applied directly on a genome.

RESUMO

INTRODUCTION: The recently-proposed Bethesda reporting system has offered clinical recommendations for each category of reported thyroid cytology, including repeated fine-needle aspiration (FNA) for non-diagnostic and atypia/follicular lesions of undetermined significance, but there are no sound indications for repeated examination after an initial benign exam. OBJECTIVE: To investigate the clinical validity of repeated FNA in the management of patients with thyroid nodules. METHOD: The present study evaluated 412 consecutive patients who had repeated aspiration biopsies of thyroid nodules after an initial non-diagnostic, atypia/follicular lesion of undetermined significance, or benign cytology. RESULTS: The majority of patients were female (93.5%) ranging from 13 to 83 years. Non-diagnostic cytology was the most common indication for a repeated examination in 237 patients (57.5%), followed by benign (36.8%), and A/FLUS (5.6%) cytology. A repeated examination altered the initial diagnosis in 70.5% and 78.3% of the non-diagnostic and A/FLUS patients, respectively, whereas only 28.9% of patients with a benign cytology presented with a different diagnosis on a sequential FNA. CONCLUSIONS: Repeat FNA is a valuable procedure in cases with initial non-diagnostic or A/FLUS cytology, but its routine use for patients with an initial benign examination appears to not increase the expected likelihood of a malignant finding.

MÉTODO: Estudo longitudinal histórico avaliando 412 pacientes consecutivos com biópsias aspirativas repetidas de nódulos da tireoide após exame inicial ND, A/FLUS, ou benigno. RESULTADOS: A citologia não diagnóstica foi a indicação mais comum para um exame repetido em 237 pacientes (57,5%), seguida por citologia inicial benigna (36,8%) e A/FLUS (5,6%). Um exame repetido alterou o diagnóstico inicial de 70,5% e 78,3% dos pacientes com citologia inicial não diagnóstica e A/FLUS, respectivamente, enquanto apenas 28,9% dos pacientes com uma citologia inicial benigna apresentaram um diagnóstico diferente em uma punção sequencial. CONCLUSÕES: Repetir a punção aspirativa é um procedimento válido para pacientes com citologia inicial não diagnóstica ou atipia/lesão folicular de significado indeterminado, mas seu uso rotineiro em pacientes com exame inicial benigno parece não aumentar a probabilidade de malignidade para este grupo. .

RESUMO

Developmental Coordination Disorder (DCD), a chronic and usually permanent condition found in children, is characterized by motor impairment that interferes with a child's activities of daily living and with academic achievement. One of the most popular tests for the quantitative diagnosis of DCD is the Movement Assessment Battery for Children (MABC). Based on the Battery's standardized scores, it is possible to identify children with typical development, children at risk of developing DCD, and children with DCD. This article describes a computational system we developed to assist with the analysis of results obtained in the MABC test. The tool was developed for the web environment and its database provides integration of MABC data. Thus, researchers around the world can share data and develop collaborative work in the DCD field. In order to help analysis processes, our system provides services for filtering data to show more specific sets of information and present the results in textual, table, and graphic formats, allowing easier and more comprehensive evaluation of the results.


O Transtorno do Desenvolvimento da Coordenação (TDC), uma condição crônica e, geralmente, encontrada em crianças, é caracterizado por comprometimento motor que interfere nas atividades de vida diária de uma criança e em seu desempenho acadêmico. Um dos testes mais populares para o diagnóstico quantitativo do TDC é a bateria Movement Assessment Battery for Children (MABC). Com base em escores padronizados da bateria, é possível identificar as crianças com desenvolvimento típico, crianças com risco de desenvolver o TDC e crianças com TDC. Este artigo descreve um sistema computacional que desenvolvemos para ajudar com a análise dos resultados obtidos na bateria MABC. A ferramenta foi desenvolvida para o ambiente web e sua base de dados fornece integração dos dados da MABC. Assim, pesquisadores de todo o mundo podem compartilhar dados e desenvolver trabalho colaborativo na área do TDC. A fim de ajudar os processos de análise, nosso sistema fornece serviços de filtragem de dados para mostrar conjuntos mais específicos de informação e apresentar os resultados em formato de texto, tabela e gráficos, permitindo a avaliação mais fácil e mais abrangente dos resultados.

RESUMO

UNLABELLED: The modified rhytidectomy incision is an alternative to the classic cervicomastoidfacial approach for parotid surgery, camouflaging the scar in barely visible areas, resulting in better cosmesis. However, there are very few studies comparing the incidence of complications and functional results of patients submitted to parotidectomy through these two different approaches. OBJECTIVE: Compare the incidence of complications and functional results of patients with benign parotid neoplasms submitted to surgery through the classical incision versus the modified rhytidectomy approach. METHOD: Retrospective cohort study evaluating the demographics, surgical and post-operative characteristics of an equally distributed group of sixty patients submitted to parotidectomy via cervicomastoidfacial incision or modified rhytidectomy approach. RESULTS: There were no significant differences in complications rates and functional results between the groups, except for a lower incidence of early facial movement dysfunction for the modified rhytidectomy approach - which was 86% lower in this group of patients. CONCLUSION: Modified rhytidectomy incision has shown comparable complication rates to those of the classic approach and a lower incidence of immediate facial movement impairment.

RESUMO

Aincisão tipo ritidectomia modificada para a abordagem da glândula parótida mostrou-se uma alternativa à clássica incisão cervicomastóideofacial, permitindo-se camuflar a cicatriz em áreas pouco visíveis com melhor resultado estético. Todavia, ainda existem poucos estudos comparando os resultados funcionais e a incidência de complicações em pacientes submetidos à parotidectomia utilizando-se essas diferentes vias de acesso. OBJETIVO: Comparar a incidência de complicações e os resultados funcionais de pacientes com neoplasias benignas da parótida abordados pela incisão clássica ou ritidectomia modificada. MÉTODO: Estudo de casos tipo coorte histórica longitudinal incluindo sessenta pacientes submetidos à parotidectomia e igualmente distribuídos entre as duas formas de incisão avaliadas, comparando-se os dados de idade, sexo, tempo de internação, volume drenado, tamanho tumoral, volume da parótida ressecada, ocorrência de disfunção de motricidade facial e fístula salivar pós-operatória. RESULTADOS: Não foram observadas diferenças significativas para complicações e resultados funcionais entre os dois grupos, exceto pela menor ocorrência de disfunção da motricidade facial imediata em pacientes submetidos à cirurgia via ritidectomia modificada, com a chance desta ocorrência ser 86% menos frequente neste grupo. CONCLUSÃO: A incisão tipo ritidectomia modificada apresenta incidência de complicações comparáveis à abordagem clássica, associada a menor ocorrência de disfunção da motricidade facial imediata.
