Type of Feet in a Mexican Population: Analysis of the Footprint Morphology and Literature Review / Tipos de pies en una Población Mexicana: Análisis de la Morfología de la Huella Plantar y Revisión de la Literatura

ABSTRACT There is no specific age when the vault of the feet is completely formed. The objective of this study was to analyze the footprint morphology and obtain the Chippaux-Smirak Index in a Mexican population to identify the type of feet and its prevalence. A database of images of the soles of both feet was analyzed. The database contained images of 1,014 persons between 2 and 73 years old from Guanajuato state, Mexico. Moreover, a literature review was performed to identify the type of feet in the Mexican population. It was observed that less than 17 % of the population have cavus foot (p= 0.018). Furthermore, less than 25 % of the population between 17 and 73 years have flatfoot 3 (p= 0.0079) in the left foot. Also, only nine articles related to the type of foot in the Mexican population were found, but most of them were performed on young population. The formation of the medial arc could be beyond the first decade of life and the relatively high prevalence of flatfoot in adult life should be studied. Finally, the results found can be useful for orthopedists, physiotherapists, clinicians, and parents who are concerned about the foot health of their children.

RESUMEN No hay una edad específica en la que la bóveda de los pies esté completamente formada. El objetivo de este estudio fue analizar la morfología de la huella de los pies y obtener el Índice de Chippaux-Smirak en una población mexicana para identificar el tipo de pie y su prevalencia. Se analizó una base de datos de imágenes de las plantas de ambos pies. La base de datos contenía imágenes de 1,014 personas de entre 2 y 73 años del estado de Guanajuato, México. Además, se realizó una revisión bibliográfica para identificar el tipo de pie en la población mexicana. Se observó que menos del 17 % de la población tiene pie cavo (p= 0,018). Además, menos del 25 % de la población entre 17 y 73 años tiene pie plano 3 (p= 0,0079) en el pie izquierdo. Además, se encontraron 9 artículos relacionados con el tipo de pie en población mexicana, pero la mayoría de ellos fueron desarrollados en población joven. La formación del arco medial podría estar más allá de la primera década de vida. Se encontró una prevalencia relativamente alta de pie plano en la vida adulta que debe ser estudiada. Finalmente, los resultados encontrados pueden ser útiles para ortopedistas, fisioterapeutas, médicos y padres preocupados por la salud de los pies de sus hijos.

The rotator cuff footprint in Filipinos: A cadaveric study

Introduction@#Rotator cuff tears are one of the common etiologies of shoulder pain. Rotator cuff repair is recommended for a patient who failed conservative treatment. Proper knowledge of the rotator cuff footprint is needed in restoring correct anatomy during the repair. The size of the footprint is important in determining the kind of repair.@*Objective@#This study aimed to define the average measurements of the rotator cuff footprint on the humerus in Filipino cadavers.@*Methods@#This is a descriptive, cross-sectional study of preserved human cadaver upper extremity specimens. We measured the length, width, and shape of the supraspinatus, infraspinatus, subscapularis, and teres minor.@*Results@#We obtained 27 upper extremity specimens. The median age of the source cadavers was 50.5 years with the equal male-to-female distribution. The mean measurement of the supraspinatus is 22.92 mm in length and 10.17 mm in width. The shape of the supraspinatus was found to be trapezoidal. The infraspinatus length was found to be 17.20 mm and the width at 10.72 mm. Its shape was found to be trapezoidal. The teres minor length was measured at 15.15 mm and the width at 11.04 mm. The shape was mostly trapezoidal but some were triangular. Finally, the subscapularis length was 17.68 mm while the width was 11.26 mm. The shape was trapezoidal or comma-shaped.@*Conclusion@#The average measurement of the rotator cuff footprint was found to be smaller in our study than reported in terms of length and width. The footprint shape was similar to the studies reported.

Reservation versus sacrifice of remnants in the footprint area in arthroscopic repair of rotator cuff tear / 中华创伤骨科杂志

Objective:To compare the clinical efficacy between reservation and sacrifice of remnants in the footprint area in arthroscopic repair of rotator cuff tear.Methods:A retrospective study was conducted to analyze the clinical data of 32 patients with rotator cuff tear plus remnants in the footprint area (2 cm < tear size <5 cm) who had been admitted to Department of Sports Medicine, The People's Hospital of Northern Jiangsu from May 2020 to July 2021. The patients were divided into 2 groups according to reservation or sacrifice of remnants in the footprint area in arthroscopic repair of rotator cuff tear. In the remnant-reservation group (16 cases): 5 males and 11 females with an age of (61.8±9.9) years, 9 left and 7 right shoulders affected, and (3.7±1.1) cm in size of rotator cuff tear; in the remnant-sacrifice group (16 cases): 4 males and 12 females with an age of (61.3±8.8) years, 8 left and 8 right shoulders affected, and (3.9±0.9) cm in size of rotator cuff tear. The 2 groups were compared in terms of visual analogue scale (VAS), American Shoulder and Elbow Surgeons (ASES) score, Constant-Murley shoulder function score (Constant score), and range of motion of the affected shoulder before surgery, 3 months after surgery and at the last follow-up. The ratio of bilateral abductor muscle strengths (affected side/healthy side) was analyzed and compared between the 2 groups, and the healing of the rotator cuff was evaluated by MRI at the last follow-up.Results:The 2 groups were comparable because there were no significant differences in all their preoperative demographic data ( P>0.05). The 32 patients were followed up for (14.3±3.5) months after surgery. At 3 months after surgery, the VAS score in the remnant-reservation group [1.0 (0.0,1.0) point] was significantly lower than that in the remnant-sacrifice group [1.0 (1.0,1.0) point] ( P<0.05), but there was no significant difference between the 2 groups in ASES score, Constant score or range of motion of the affected shoulder ( P>0.05). At the last follow-up, the ASES score, forward flexion, abduction and ratio of bilateral abductor muscle strengths (affected side/healthy side) in the remnant-reservation group [(96.1±4.8) points, 170.0 (170.0,170.0)°, 160.0 (160.0,170.0)°, and 85.5%±13.8%]were significantly better than those in the remnant-sacrifice group [(91.4±5.9) points, 160.0 (160.0,170.0)°, 150.0 (140.0,155.0)°, and 72.6%±16.9%] ( P < 0.05), but there were no statistically significant differences between the 2 groups in VAS score, Constant score, neutral external rotation angle, or body-side internal rotation ( P>0.05). The Sugaya grading for MRI rotator cuff healing was significantly different between the 2 groups at the last follow-up ( P<0.05). Conclusion:In arthroscopic repair of rotator cuff tear, reservation of remnants in the footprint area can significantly relieve postoperative shoulder pain, and has obvious advantages in restoration of shoulder forward flexion, abduction and abductor muscle strength, leading to better healing of the rotator cuff and the large nodule than the remnant-sacrifice technique.

DETERMINATION OF SEX FROM FOOTPRINT DIMENSIONS AMONG NUPE ETHNIC GROUP IN MINNA NIGER STATE

Determination of personal identity is a basic and pivotal step in forensic investigations and medico legal practices. In anthropological cases, forensic identification is generally carried out through examination of the body or the remains for prints from the body. Thus, the footprint becomes an invaluable index of identification particularly when the whole body is very badly mutilated. This study was carried out to determine the relationship between footprint dimensions and sex among individuals of Nupe ethnic group of Niger State. Sample size of four hundred and twenty one (421) subjects, two hundred and eighty three (283) males and one hundred and thirty eight (138) females were used in this study. The footprints were gotten by placing the volunteers' foot on the ink pad and it was then transferred on an A4 paper, where the footprint dimensions were later measured with a meter rule. The results of this study show that sex differences were highly significant using toe lengths and breadth (P? 0.01) but the footprint indices shows no statistical significance. Footprint dimension is sexually dimorphic. Footprint dimensions can be used to determine sex in addition to or in absence of skeletons such as long bones and skull. It can be applied in forensics for medico legal cases, shoe designing, fashion design and industrial design to optimize products

5° Congreso Nacional y 1° Internacional de Ciencias Ambientales "Las Ciencias Ambientales en el Antropoceno". Emisiones generadas y evitadas / 5th National and 1st International Congress of Environmental Sciences "Environmental Sciences in the Anthropocene". Emissions generated and avoided

RESUMEN Las actividades académicas, como los congresos, son muy importantes para la investigación y el desarrollo; sin embargo, las emisiones de carbono derivadas de la realización de eventos presenciales han mostrado estar muy por encima de las que producen eventos en línea. El objetivo de este trabajo fue estimar las emisiones generadas por el 5º Congreso Nacional y 1º Internacional de Ciencias Ambientales "Las Ciencias Ambientales en el Antropoceno", celebrado virtualmente, en su mayor parte. Se estimaron las emisiones del uso directo de computadores y de software (emisiones de los computadores, emisiones de la transferencia de los datos) y las emisiones de otras fuentes (reuniones de los organizadores, búsquedas y visitas a la página Web, uso de monitores externos y lámparas), así como las emisiones evitadas por transporte aéreo y terrestre. El congreso emitió 4,8 tCO2eq y evitó 33 tCO2eq. El desarrollo de eventos online o híbridos es más sostenible ambientalmente y podría ser más accesibles, a un mayor número de personas.

ABSTRACT Academic activities such as conferences are very important for research and development, however, carbon emissions derived from face-to-face events have been shown to be much higher than those produced by online events. The aim of this work was to estimate CO2 emissions generated by the 5th National Congress and 1st International Congress of Environmental Sciences "Environmental Sciences in the Anthropocene". Emissions from direct use of computers and software (emissions from computers, emissions from data transfer) and emissions from other sources (meetings of the organizers, searches and visits to the website, use of external monitors and lamps), as well as emissions avoided by air and land transport. The congress emitted 4.8 tCO2eq and avoided 33 tCO2eq. The development of online or hybrid events is more environmentally sustainable and could be more accessible to a greater number of people.

An assessment of the urban water footprint and blue water scarcity: A case study for Van (Turkey) / Uma avaliação da pegada hídrica urbana e da escassez de água azul: um estudo de caso para Van, Turquia

Today, most of the world’s population faces water scarcity, while global warming, urbanization, industrialization and population increases continue to increase the severity of the pressure on water resources. Management ofwater resources plays a key role in the sustainability of agricultural production. The water footprint (WF) is different in comparison to other water statistics because it takes direct and indirect water consumption into account, and helps in the management of water resources. Within this context, the WF of Van province, which is Turkey’s most easterly located arid region, was calculated from 2004 to 2019. The study area covers lake Van, which is Turkey's largest lake, and the Van basin with an area of 23.334km² and a population of 1.136.757 (2019). In the calculations, crop (WFcrop), livestock (WFlivestock), and domestic and industrial water footprints (WFdomestic+industrial) were evaluated separately, and blue and green water footprints (WFblue and WFgreen) were analyzed in detail. According to the results, the average WF of Van province was found to be 8.73 billionm3 year-¹. Throughout the province, 87.6% of the WF is composed of WFcrop, 4.9% is WFlivestock and 7.5% is WFdomestic+industrial. Of the WFcrop, 62.5% depends on WFblue, i.e., freshwater. Most of the WFlivestock consisted of dairy cattle (49%) and sheep (38%). The average WFdomestic+industrial for 2004 to 2019 was 0.64billion m³ year-¹. The average per capita water footprint of Van province was found to be 889.9m³ year-¹ capita-¹. In addition, the province is classified as severe water scarcity (257%). This study is one of the first province-based calculations of WF in Turkey and is the first study to bring a different aspect to published literature by including residual soil moisture from the winter months. As a result of this study, the WFblue of the [...].

A gestão dos recursos hídricos desempenha papel fundamental na sustentabilidade da produção agrícola. A pegada hídrica (WF) é diferente em comparação com outras estatísticas hídricas porque leva em consideração o consumo direto e indireto de água e auxilia na gestão dos recursos hídricos. Nesse contexto, o WF da província de Van, que é a região árida localizada mais a leste da Turquia, foi calculado de 2004 a 2019. A área de estudo cobre o lago Van, que é o maior lago da Turquia, e a bacia de Van, com uma área de 23,334 km² e uma população de 1.136.757 (2019). Nos cálculos, as pegadas hídricas de safra (WFcrop), pecuária (WFlivestock) e doméstica e industrial (WFdomestic+industrial) foram avaliadas separadamente, e as pegadas hídricas azul e verde (WFblue e WFgreen) foram analisadas em detalhes. De acordo com os resultados, o WF médio da província de Van foi encontrado em 8,73 bilhões de m³ ano-¹. Em toda a província, 87,6% do WF são compostos por WFcrop, 4,9% são WFlivestock e 7,5% são WFdomestic+industrial. Do WFcrop, 62,5% dependem do WFblue, ou seja, de água doce. A maior parte do gado WFlivestock era composto por gado leiteiro (49%) e ovelhas (38%). O WFdomestic+industrial médio de 2004 a 2019 foi de 0,64 bilhão de m³ ano-¹. A pegada hídrica per capita média da província de Van foi encontrada em 889,9 m³ ano-¹ capita-¹. Além disso, a região é classificada como grave escassez de água (257%). Este estudo é um dos primeiros cálculos de WF baseados em províncias na Turquia e é o primeiro estudo a trazer um aspecto diferente para a literatura publicada, incluindo a umidade residual do solo dos meses de inverno.

Ultra-processed food intake and diet carbon and water footprints: a national study in Brazil

ABSTRACT OBJECTIVE To study the association between ultra-processed food consumption and carbon and water footprints of the Brazilian diet. METHODS Cross-sectional analysis on data collected in 2008-2009 on a probabilistic sample of the Brazilian population aged ≥ 10 years (n = 32,886). Individual food intake was assessed using two 24-hour food records, on non-consecutive days. The environmental impact of individual diets was calculated by multiplying the amount of each food by coefficients that quantify the atmospheric emissions of greenhouse gases in grams of carbon dioxide equivalent (carbon footprint) and freshwater use in liters (water footprint), both per gram or milliliter of food. The two coefficients consider the food life cycle 'from farm to fork.' Crude and adjusted linear regression models and tests for linear trends assessed the association between the ultra-processed food contribution to total energy intake (quintiles) and the diet carbon and water footprints. Potential confounders included age, sex, education, income, and region. Total energy intake was assessed as a potential mediation variable. RESULTS In the crude models, the dietary contribution of ultra-processed foods was linearly associated with the carbon and water footprints of the Brazilian diet. After adjustment for potential confounders, the association remained significant only regarding the diet water footprint, which increased by 10.1% between the lowest and highest quintile of the contribution of ultra-processed foods. Additional adjustment for total energy intake eliminated this association indicating that the dietary contribution of ultra-processed foods increases the diet water footprint by increasing energy intake. CONCLUSIONS The negative impact of ultra-processed foods on the diet water footprint, shown for the first time in this study, adds to the negative impacts of these foods, already demonstrated regarding dietary nutrient profiles and the risk for several chronic non-communicable diseases. This reinforces the recommendation to avoid ultra-processed foods made in the official Brazilian Dietary Guidelines and increasingly in dietary guidelines of other countries.

Food consumption in Brazil: influence of beef on environmental impact and nutritional quality of the diet / Consumo alimentar no Brasil: influência da carne bovina no impacto ambiental e na qualidade nutricional da dieta

ABSTRACT OBJECTIVE To estimate beef consumption and its influence on carbon and water footprints, as well as to improve the nutritional quality of the Brazilian diet. METHODS The amount of beef and other foods consumed was evaluated by two 24-hour food records in a representative sample of the Brazilian population ≥ 10 years of age (n = 32,853) from 2008 to 2009. The environmental impact of the diet considered the coefficients of the carbon footprint (gCO2 and/kg) and the water footprint (liters/kg) of the foods, as well as their nutritional quality considering the nutrient composition of each food associated with the prevention of nutritional deficiencies or the increase/decrease in chronic disease risk. Linear and logistic regression models, crude and adjusted for sex, age, education, income, region, and area, were used to respectively study the association of fifths of the caloric contribution of beef with the environmental impacts of the diet and inadequate nutrient intake. RESULTS Carbon and water footprints and protein, iron, zinc, vitamin B12, saturated fat, and sodium contents were higher in the fraction of the diet composed of beef, whereas fiber and added sugar contents were higher in the fraction composed by the other foods. Dietary beef contribution was directly associated with the carbon and water footprints of the diet and the risk of saturated fat and sodium excess, besides fiber insufficiency, inversely associated with the risk of protein, iron, zinc, and vitamin B12 insufficiency. CONCLUSION Reducing beef consumption in Brazil would also reduce the carbon and water footprints of the diet, as well as the risk of chronic diseases related to food. Therefore, in order not to increase the risk of nutritional deficiencies, monitoring the increased intake of other foods rich in protein, iron, zinc, and vitamin B12 is suggested.

RESUMO OBJETIVO Estimar o consumo de carne bovina e a sua influência nas pegadas de carbono e na pegada hídrica, bem como mesurar a qualidade nutricional da dieta no Brasil. MÉTODOS A quantidade consumida de carne bovina e dos demais alimentos foi avaliada por dois registros alimentares de 24 horas em amostra representativa da população brasileira ≥ 10 anos de idade (n = 32.853) entre 2008 e 2009. O impacto ambiental da dieta considerou os coeficientes da pegada de carbono (gCO2e/kg) e da pegada hídrica (litros/kg) dos alimentos, bem como sua qualidade nutricional considerando a composição de cada alimento em nutrientes associados à prevenção de deficiências nutricionais ou ao aumento/diminuição do risco de doenças crônicas. Modelos de regressão linear e logística, brutos e ajustados para sexo, idade, escolaridade, renda, região e área, foram utilizados para estudar, respectivamente, a associação de quintos da contribuição calórica de carne bovina com os impactos ambientais da dieta e com a ingestão inadequada de nutrientes. RESULTADOS As pegadas de carbono e hídrica e os teores de proteína, ferro, zinco, vitamina B12, gordura saturada e sódio foram maiores na fração da dieta composta por carnes bovinas, enquanto o teor de fibra e de açúcar de adição foram maiores na fração composta pelos demais alimentos. A contribuição dietética de carne bovina mostrou-se associada diretamente com as pegadas de carbono e hídrica da dieta e com o risco de ingestão excessiva de gordura saturada e de sódio, além de ingestão insuficiente de fibra, associando-se inversamente com o risco de ingestão insuficiente de proteína, ferro, zinco e vitamina B12. CONCLUSÃO A redução no consumo de carne bovina no Brasil diminuiria as pegadas de carbono e hídrica da dieta, assim como o risco de doenças crônicas relacionadas à alimentação. Portanto, para não aumentar o risco de deficiências nutricionais, é sugerido o acompanhamento do aumento da ingestão de outros alimentos fontes de proteína, ferro, zinco e vitamina B12.

Feature Extraction of Foot Movement Based on Plantar Pressure Distributions / 医用生物力学

Objective To analyze the statistical behavior of plantar pressure distribution, extract the characteristics of foot movement, and provide references for application of gait recognition in medical clinical diagnosis, rehabilitation training and public health. Methods The collected foot pressure data were prepossessed, statistical analysis on the data was performed, the footprint reconstruction was realized, and the pressure distribution rates of the footprints, segmented regions and each region were compared and analyzed, so as to decompose the foot motion characteristics. Results Based on the cross point of pressure peak curve in different regions, the plantar region was divided into toe region, metatarsal region, arch region and heel region, which could accurately extract the foot movement characteristics. Conclusions The peak plantar pressure is used to extract the characteristics of foot movement, which is divided into landing stage, whole foot contact stage, heel tiptoe stage and ground off stage.

Assessment of environmental sustainability in renal healthcare / Journal of Rural Medicine

The health effects of climate change are becoming increasingly important; there are direct effects from heatwaves and floods, and indirect effects from the altered distribution of infectious diseases and changes in crop yield. Ironically, the healthcare system itself carries an environmental burden, contributing to environmental health impacts. Life cycle assessment is a widely accepted and well-established method that quantitatively evaluates environmental impact. Given that monetary evaluations have the potential to motivate private companies and societies to reduce greenhouse gas emissions using market mechanisms, instead of assessing the carbon footprint alone, we previously developed a life cycle impact assessment method based on an endpoint that integrates comprehensive environmental burdens into a single index—the monetary cost. Previous investigations estimated that therapy for chronic kidney disease had a significant carbon footprint in the healthcare sector. We have been aiming to investigate on the environmental impact of chronic kidney disease based on field surveys from the renal department in a hospital and several health clinics in Japan. To live sustainably, it is necessary to establish cultures, practices, and research that aims to conserve resources to provide environmentally friendly healthcare in Japan.

Carbon footprint of the Brazilian diet / Pegada de carbono da dieta no Brasil

ABSTRACT OBJECTIVE: To estimate the carbon footprint of the Brazilian diet and of sociodemographic strata of this population. METHODS: Carbon footprint of the diet was estimated based on data from two 24-hour diet records, obtained in 2008 and 2009, from a probabilistic sample of the Brazilian population aged 10 years and over (n = 34,003) and on environmental impact coefficients of food and culinary preparations consumed in Brazil (gCO2e/kg). Means with 95% confidence intervals of food consumption (kcal/person/day) and the carbon footprint of the diet (gCO2e/person/day and in gCO2e/2,000kcal) were calculated for the population as a whole and for strata according to sex, age, income, education, macro-regions and Federative Unit. Linear regression models were used to identify significant differences (p < 0.05) in the dietary carbon footprint of different sociodemographic strata. RESULTS: The average carbon footprint of the Brazilian diet was 4,489gCO2e/person/day. It was higher for males, for the age group from 20 to 49 years and for the North and Midwest regions, and tended to increase with income and education. The pattern of association of footprint with sociodemographic variables did not change substantially with adjustment for differences in the amount of food consumed, except for a reduction in the relative excess of the footprint among males and an increase in the relative excess of the footprint in the Midwest region. CONCLUSION: The carbon footprint of the Brazilian diet exceeds by about 30% the footprint of the human diet, which could simultaneously meet the nutritional requirements of a healthy diet and the global goal of containing the increase in the planet's average temperature. The pattern of association of this footprint with sociodemographic variables can help identify priority targets for public actions aimed at reducing the environmental impacts of food consumption in Brazil.

RESUMO OBJETIVO: Estimar a pegada de carbono da dieta brasileira e de estratos sociodemográficos dessa população. MÉTODOS: A pegada de carbono da dieta foi estimada com base nos dados de dois registros alimentares de 24 horas, obtidos em 2008 e 2009, de uma amostra probabilística da população brasileira com 10 ou mais anos de idade (n = 34.003) e em coeficientes de impacto ambiental de alimentos e preparações culinárias consumidos no Brasil (gCO2e/kg). Médias com intervalos de confiança de 95% do consumo alimentar (kcal/pessoa/dia) e da pegada de carbono da dieta (gCO2e/pessoa/dia e em gCO2e/2.000kcal) foram calculadas para o conjunto da população e para estratos segundo sexo, idade, renda, escolaridade, macrorregiões e Unidade Federativa. Modelos de regressão linear foram utilizados para identificar diferenças significativas (p < 0,05) na pegada de carbono da dieta de diferentes estratos sociodemográficos. RESULTADOS: A pegada média de carbono da dieta brasileira foi de 4.489gCO2e/pessoa/dia. Foi maior para o sexo masculino, para a faixa etária de 20 a 49 anos e para as regiões Norte e Centro-Oeste, e tendeu a aumentar com a renda e a escolaridade. O padrão de associação da pegada a variáveis sociodemográficas não se alterou substancialmente com o ajuste para diferenças na quantidade consumida de alimentos, exceto por uma redução no excesso relativo da pegada entre homens e pelo aumento no excesso relativo da pegada na região Centro-Oeste. CONCLUSÃO: A pegada de carbono da dieta brasileira excede em cerca de 30% a pegada da dieta humana que poderia atender, simultaneamente, os requisitos nutricionais de uma dieta saudável e a meta global de contenção do aumento da temperatura média do planeta. O padrão de associação dessa pegada às variáveis sociodemográficas pode auxiliar na identificação de alvos prioritários para ações públicas que visem a reduzir os impactos ambientais do consumo alimentar no Brasil.

Distribution update, conservation status and color in life of the rare Amazonian snake, Eutrachelophis papilio Zaher and Prudente 2019 (Serpentes: Xenodontini)

The rare Amazonian snake Eutrachelophis papilio is known from only five individuals, from four localities, belonging to its type-series, the more recent collected over 10 years ago. Here, we expand its distribution and describe its color in life for the first time. We also provide an estimate of its distribution area using the minimum convex polygon method and identify the values of anthropic pressure within its known distribution range with the Human Footprint Index. The new occurrence is located 291 km from the nearest known locality and its distribution is associated with pristine forests. Considering its rarity, and the absence of demographic and biological data, we suggest that the species should be classified as Data Deficient by IUCN criteria. (AU)

Estimativa do dispêndio de água virtual nas exportações brasileiras no período de 2003 a 2014 / Estimation of virtual water use in Brazilian exports from 2003 to 2014

RESUMO O conceito de água virtual tem sido muito utilizado como importante indicador de consumo, sendo cada vez mais aceito na literatura, constituindo-se da água incorporada à produção de um bem ou serviço. Visando a estimar o volume de água virtual presente nos 25 principais produtos da pauta de exportação brasileira no período 2003-2014, utilizou-se o método de pesquisa exploratória a partir dos principais produtos que representavam aproximadamente 60% do montante arrecadado. Os resultados indicaram inflexão entre a relevância dos produtos manufaturados e dos produtos básicos (principalmente minério de ferro e soja) no período de 2009-2010, com apenas quatro produtos respondendo, em 2014, por 32% da receita auferida pelo País. Como consequência, a estimativa do dispêndio de água virtual realizada para os produtos avaliados indicou que o Brasil despendeu, em média, 191 Gm3.ano-1 (6.025 m3.s-1), com os produtos básicos respondendo por 95% desse volume. Considerando-se apenas 2014, essa vazão elevou-se para 7.836 m3.s-1, aproximadamente 14 vezes superior à demanda para abastecimento da população urbana brasileira.

ABSTRACT The Virtual Water concept has long been used as an important indicator of water consumption, increasingly being accepted in the literature, becoming the embedded water in the production of a good or service. In order to estimate the volume of virtual water present in the top 25 products of Brazilian exports in the period 2003-2014, we used the exploratory method from the main products that represented approximately 60% of the collected amount. Results indicated a shift between the relevance of manufactured products and commodities (mainly iron ore and soybeans) in the 2009-2010 period, with only four products accounting in 2014 for 32% of the revenue earned by the country. As a result, the estimated virtual water expenditure for the products evaluated indicated that Brazil spent, on average, 191 Gm3.year-1 (about 6,025 m3.s-1), with commodities accounting for 95% of this volume. Considering only 2014, this flow increased to about 7,836 m3.s-1, 14 times higher than the supply demand of the Brazilian urban population.

Diferencia de la huella plantar (antes y después de realizar ejercicio físico) de estudiantes de primer semestre, aparentemente sanos, de la facultad de cultura física deporte y recreación de la universidad santo tomás de colombia, sede campus san alberto magno

Introducción. Durante la evaluación funcional es necesario diagnosticar la distribución de las cargas corporales de los sujetos, uno de los mecanismos más efectivos para dicha evaluación es el protocolo del fotopodograma, en el cual se evalúa la huella plantar antes y después de realizar ejercicio físico. Métodos. Se realizó el protocolo del fotopodograma a veinte y ocho estudiantes universitarios, la actividad física de intensidad moderada consistió en una carrera continua, con intensidad moderada durante 15 minutos alrededor de la pista de atletismo. Resultados. Se encontró que hubo un mayor promedio en el tipo de pie normal antes y después de hacer actividad física, así mismo se encontró cambios de la huella con la actividad física aunque estos no son estadisticamente significativos. Conclusiones. A pesar de que no hubo cambios significativos en las tomas pre y pos, sí se evidencia que esta evaluación se debe realizar después de la actividad física para reconocer con mayor precisión las cargas que se acomodan en la huella plantar.

Introduction: During functional evaluation, it is necessary to diagnose the distribution of body burden in the subjects. One of the most effective mechanisms to do so, is the protocol of photopodogram, which evaluates footprint before and after doing exercise. Method: Photopodogram protocol was carried out. Twenty-eight undergraduate students took part. The physical activity consisted of a continuous race, with a moderate intensity during 15 mins, around the running tracks. Results: It was found that there was a higher average in the type of normal cake before and after doing physical activity, likewise there were changes in the footprint with physical activity although these are not statistically significant. Conclusions: Even though no significant changes appeared in the pre and post intakes, there is an evidence that this evaluation must be carried out after the physical exercise, to detail, with much more precision, the loads that settle in the footprint.

Resumen: Introducción: Las alteraciones de la huella plantar en el niño es causa de preocupación en los padres de familia. Objetivo: Determinar la frecuencia de alteraciones de la huella plantar en escolares. Determinar si existe relación entre el sobrepeso y la obesidad con la presencia de alteraciones de la huella plantar. Material y métodos: Estudio observacional, transversal y prospectivo. Se evaluaron 959 escolares de seis a 13 años de edad. Se registró peso, talla, índice de masa corporal para la edad. La huella plantar se catalogó en pie plano y pie cavo utilizando el índice del arco. Para el análisis y comparación estadística se utilizó el programa SPSS versión 24 con las pruebas χ2 y ANOVA. Resultados: Se revisaron 530 niños (55.3%) y 429 niñas (44.7%). La media de edad fue de 8.97 años. Se observaron 182 niños (19%) con alteración de la huella plantar, 42.3% con pie plano y 57.7% con pie cavo. Ninguno mostró sintomatología del pie. Ciento treinta y un niños tenían sobrepeso y 52 obesidad, sin influir en la presencia de alguna alteración de la huella plantar (p = 0.20). La relación de pie plano fue mayor en los hombres (2.5:1) y de pie cavo fue mayor en las mujeres (1.3:1). Conclusiones: En nuestro grupo de estudio se encontró mayor prevalencia del pie cavo en comparación con el pie plano. El peso corporal no influyó en las alteraciones de la huella plantar.

Abstract: Introduction: Alterations in the plantar footprint in the child are a cause for concern in parents. Objective: Determine the frequency of plantar footprint alterations in school children. Determine if there is a relationship between overweight and obesity with the presence of alterations of the plantar footprint. Material and methods: Observational, transversal and prospective study. 959 schoolchildren aged six to 13 were evaluated. Weight, size, body mass index for age were recorded. The plantar footprint was cataloged on flat foot and cavus foot using the arch index. For statistical analysis and comparison, the SPSS version 24 program was used with the χ2 and ANOVA tests. Results: 530 children (55.3%) and 429 girls (44.7%). The median age was 8.97 years. 182 children were found (19%) with alteration of the plantar footprint, 42.3% with flat foot and 57.7% with cavus foot. None of them had foot symptoms. 131 children were overweight and 52 obese, without influencing the presence of any alteration of the plantar footprint (p = 0.20). The flat-foot ratio was higher in men (2.5:1) and standing cavus major in women (1.3:1). Conclusions: In our study group we find a higher prevalence of the cavus foot compared to the flat foot. Body weight did not influence plantar footprint alterations.

Methane emissions of extensive grazing breeding herds in relation to the weaning and yearling stages in the Eastern Plains of Colombia / Emisiones de metano en hatos de carne en pastoreo extensivo relacionadas con los períodos de destete y levante en los Llanos

ABSTRACT A substantial proportion of beef production in Colombia originates in its extensive Eastern Plains. However, in this scenario and in a global context, demand for cattle production increasingly requests that it satisfies social and environmental expectations in addition to being economically efficient. A dataset containing five-year long records of cow-calf production systems collected at Carimagua Research Centre located in the Meta Department was retrospectively interrogated to understand the liveweight (LW)-derived flux matrix dynamics of methane (CH4) emissions. Estimated total CH4 (kg) emissions during the gestation period, were similar between conventional weaned (CW; 37.86 ± 0.506 kg) and early weaned (EW; 37.47 ± 0.476 kg) cows. However, averaged over two lactations, total CH4 emissions were larger (p < 0.0001) in CW cows (38.67 ± 0.456 kg) than in their EW (14.40 ± 0.435 kg) counterparts. Total gas emissions from birth to comparable commercial yearlings age were higher (p < 0.0001) for CW (43.11 ± 0.498 kg) calves than for EW (40.27 ± 0.472 kg) calves. It was concluded that mid and long-term pastoral datasets and new concerns are well suited to understand different contexts and adaptations to the contemporary weather conditions. Nevertheless, conventional farming systems will be less environmentally vulnerable if EW management practices involve the strategic and temporal use of improved pastures. The roles of veterinary medicine and animal sciences are briefly discussed in the context of unprecedented climate variability to provide a guide to the uncertain future.

RESUMEN Una proporción substancial de la producción de carne de res en Colombia se origina en sus Llanos Orientales. Sin embargo, allí, así como en un contexto global, dicha producción ganadera debe ser económicamente eficiente y satisfacer expectativas sociales y ambientales. Considerando algunos de esos intereses, se analizaron cinco años de eventos productivos y de manejo del destete implementados en el Centro de Investigaciones Carimagua, localizado en el departamento del Meta, para interpretar en vacas de carne y sus crías las dinámicas de peso vivo asociadas con emisiones derivadas de metano (CH4). Emisiones totales de CH4 (kg) durante la gestación fueron similares entre las vacas destetadas convencionalmente (CW; 37.86 ± 0.506 kg) y aquellas destetadas tempranamente (EW; 37.47 ± 0.476 kg). Sin embargo, el promedio de dos lactancias demostró mayores (p < 0.0001) emisiones en vacas CW (38.67 ± 0.456 kg) que en vacas EW (14.40 ± 0.435 kg). Emisiones acumuladas entre el nacimiento y el levante fueron mayores (p < 0.0001) en terneros CW (43.11 ± 0.498 kg) que en terneros EW (40.27 ± 0.472 kg). Se concluyó que nuevos cuestionamientos y datos de pastoreo de mediano y largo plazo son apropiados para entender contextos innovadores y adaptaciones a las condiciones climáticas actuales. Sin embargo, el manejo convencional en las fincas será menos vulnerable al medio ambiente si prácticas de destete temprano son introducidas considerando el uso estratégico y temporal de pastos mejorados. Los roles de la medicina veterinaria y las ciencias animales se discuten brevemente en el contexto de la variabilidad climática existente.

Footprint lesion: a mirror image of an endometrial polyp

Endometrial polyps may present with a variety of symptomatology. They are mostly benign and commonly encountered in the reproductive age group. Hysteroscopy is an emerging tool for diagnostic as well as a therapeutic purposes. We report a case of endometrial polyp diagnosed on hysteroscopy, with a “footprint”, that is contact lesion visible. This is a relatively rare phenomenon, and there is sparse information and literature regarding this entity. Hence the true nature of its effects is yet unknown.
