Abstract Purpose: To analyze diabetes mellitus (DM) in a multifactorial manner with the consumption of sugar-sweetened beverages (SSB) and variables like nutritional status, sex, genetic predisposition, age and ethnicity; in order to determine the relationship between BGA and DM in the Mazahua Otomí (MO) community. Methodological design: This quantitative survey on social and nutritional variables was designed, validated and applied. A logistic model was developed to find the relationship of DM in relation to the variables: SSB consumption, sex, genetic predisposition, age, body mass index and ethnicity. Results: The Mazahua otomi community has a monthly family income below the extreme poverty line; they do not have disease control: 68% are obese or overweight and SSB consumption is medium to high in 90% of the population. In a multifactorial manner and according to the model, there is a probability of manifesting DM depending on the variables mentioned above; while, with the exception of nutritional status and age, the others are the most significant. In taste and preferences, 52% opt for the Coca-Cola SSB brand. Research limitations: The results found should be complemented in other case studies in communities with similar characteristics and a broader probabilistic population sample. Finding: In the MO community there is a relationship between BGA consumption and DM and there is no control of the disease. This work contributes to the design of public policies to prevent health damage because of excessive consumption of SSB and its relationship with DM; likewise, those policies that rescue and promote good nutritional practices of the communities of indigenous peoples.

Resumen Objetivo: Analizar en forma multifactorial la diabetes mellitus (DM) con el consumo de las bebidas gaseosas azucaradas (BGA) y de las variables estado nutricional, sexo, predisposición genética, edad y etnia, para determinar la relación de las BGA y la DM en la comunidad Mazahua Otomí (MO). Diseño Metodológico: El estudio fue cuantitativo. Se diseñó, validó y aplicó una encuesta estructurada sobre variables sociales y nutricionales. Se elaboró un modelo logístico para encontrar la relación de DM con las variables: consumo de BGA, sexo, predisposición genética, edad, índice de masa corporal y etnia. Resultados: En la comunidad MO que se investigó un padre de familia promedio tiene un ingreso mensual por debajo de la línea de pobreza extrema y no existe control de la enfermedad de estudio: 68% tiene obesidad o sobrepeso y el consumo de BGA es entre medio y alto en 90% de la población. En forma multifactorial, hay probabilidad de manifestar la DM en función de las variables antes señaladas; mientras que, a excepción de estado nutricional y la edad, las demás son las más significativas. En gustos y preferencias, 52% opta por la marca de BGA Coca-Cola. Limitaciones de la investigación: Los resultados encontrados deberán complementarse con estudios de caso en comunidades con características similares y una muestra poblacional probabilística más amplia. Hallazgos: En la comunidad MO existe una relación entre el consumo de BGA y la DM y no hay control de la enfermedad. Este trabajo aporta al diseño de políticas públicas de prevención del daño a la salud por el consumo excesivo de BGA y su relación con la DM. De igual manera aquellas políticas públicas que rescaten y fomenten las buenas prácticas nutritivas entre las comunidades de los pueblos originarios.

ABSTRACT Introduction: Cleft lip and palate (CLP) is a craniofacial alteration of multifactorial etiology. The diet of children with CLP can become deficient, compromising growth and development. Objective: To determine the evolution of the pre- and post-surgical nutritional status and feeding practices in infants between 6 and 24 months of age, with cleft lip and/or palate who attended the “Operation Smile” Foundation Clinic from September 2020 to May 2021. Materials and methods: This was an observational and prospective study with an analytical component. 50 children with a diagnosis of CLP from 6 to 24 months of age were included. Nutritional status was evaluated according to National Health Ministry standards. Results: 50 infants from 6 to 24 months were evaluated, 60% were between 6 -11 months, 64% were males, 54% came from the rural areas. 86% underwent primary lip closure and 12% cleft palate reconstruction. 88% of the children were breastfed. The pre-surgical nutritional status was adequate (94%) by weight for age indicator. Post surgery there was a significant difference of 0.927 kg for weight for height (p < 0.001), the same for weight for age (p < 0.001). For height for age, a difference of 0.8 cm was found (p=ns). Conclusions: The nutritional status of children with cleft lip or palate improves 4 months after reconstructive surgery for the indicators weight for age and weight for height.

Resumo Objectivos: Estudar o tipo de queda de cabelo mais frequente em diferentes faixas etárias e a deficiência prevalente de micronutrientes associada à queda de cabelo. Comparar a associação dos níveis séricos de ferritina, vitamina D e vitamina B12 com queda de cabelo entre casos e controles. Métodos: Este foi um estudo transversal que incluiu um total de 100 indivíduos com 50 casos de queda de cabelo e 50 controles pareados por idade e sexo. Os níveis séricos de vitamina D, vitamina B12 e ferritina foram medidos em todos os indivíduos. Resultados: A maioria dos sujeitos tinha entre 20 e 30 anos de idade. Houve predomínio do eflúvio telógeno seguido da alopecia androgenética masculina em todas as faixas etárias. As mulheres apresentaram níveis consideravelmente mais baixos de ferritina sérica em comparação aos homens entre os casos, com valor p de 0,0001. A vitamina D, a vitamina B12 e a ferritina sérica foram significativamente baixas entre os casos em comparação aos controles, com valores de p de 0,0001, 0,01 e 0,006, respectivamente. Conclusão: Este estudo sugere que baixos níveis séricos de vitamina B12 e ferritina sérica e particularmente vitamina D podem desempenhar um papel apreciável na perda de cabelo, especialmente no eflúvio telógeno entre as mulheres. A avaliação destes parâmetros poderia ajudar o médico a optar por uma modalidade terapêutica mais precisa, mas a identificação da etiologia exacta continua a ser uma preocupação primordial, uma vez que é multifactorial, o que abre o caminho para um tratamento adequado e eficaz.

Abstract Objectives: The objective of this study was to study the most frequent type of hair loss in different age groups, and the prevalent micronutrient deficiency linked to hair loss and to compare the association of serum ferritin, vitamin D, and vitamin B12 levels with hair loss among cases and controls. Methods: This was a cross-sectional study which included a total of 100 subjects with 50 hair loss cases and 50 age and sex-matched controls. Serum levels of vitamin D, vitamin B12, and ferritin were measured in all subjects. Results: Most of the subjects were between 20 and 30 years of age. There was a predominance of telogen effluvium followed by male androgenetic alopecia in all age groups. Females had considerably lower levels of serum ferritin compared to males among cases, with p-value of 0.0001. Vitamin D, vitamin B12, and serum ferritin were significantly low among cases compared to controls, with p-values of 0.0001, 0.01, and 0.006, respectively. Conclusion: This study suggests that low levels of serum vitamin B12 and serum ferritin and particularly vitamin D might play an appreciable role in hair loss especially telogen effluvium among females. Evaluation of these parameters could aid the clinician in opting for a more precise therapeutic modality, but identification of the exact etiology remains a primary concern as it is multifactorial, which paves path to appropriate and effective treatment.

Resumen: El suicidio es un fenómeno que además de las pérdidas humanas que involucra, repercute negativamente en familiares y allegados, produciendo a su vez enormes gastos en el sistema sanitario. En Uruguay, la tasa de suicidio no solo ha experimentado un aumento sostenido, representando una preocupación constante para las autoridades, sino que suele ser una de la más altas de Latinoamérica, en 2022 fue de 23,08 cada 100.000 habitantes. Reconociendo que el suicidio es un fenómeno multifactorial grave, diversos estudios han indagado sobre la posible correlación entre la presencia de litio en agua corriente y tasas de suicidio, habiéndose observado una relación inversa, lo que permitiría considerar el litio como eventualmente protector de la conducta suicida. El presente estudio pretende abordar dicha correlación en los departamentos de Rocha y Montevideo, de Uruguay. Los resultados obtenidos no son concluyentes. En cuanto a las concentraciones de litio presentes en agua corriente, en general son menores a las señaladas en otros estudios como protectoras (30 µ/L). Es necesario profundizar en este eje de discusión, como en otros, para obtener un diagnóstico más detallado de este complejo y sentido fenómeno.

Abstract: Suicide is a phenomenon that, in addition to the human losses it involves, has a negative impact on family members and acquaintances, leading to enormous costs in the healthcare system. In Uruguay, the suicide rate has not only experienced a sustained increase, representing a constant concern for authorities, but it also tends to be one of the highest in Latin America, reaching 23.08 per 100,000 inhabitants in 2022. Recognizing that suicide is a serious multifactorial phenomenon, several studies have investigated the possible correlation between the presence of lithium in tap water and suicide rates, noting an inverse relationship. This suggests that lithium could potentially be considered protective against suicidal behavior. This study aims to address this correlation in the departments of Rocha and Montevideo, Uruguay. The results obtained are inconclusive. Regarding the concentrations of lithium present in tap water, they are generally lower than those indicated in other studies as protective (30 μg/L). It is necessary to delve deeper into this axis of discussion, as in others, to obtain a more detailed diagnosis of this complex and profound phenomenon.

Resumo: O suicídio é um fenómeno que, além das perdas humanas que envolve, tem um impacto negativo nos familiares e amigos, produzindo enormes gastos no sistema de saúde. No Uruguai, a taxa de suicídio não só tem registado um aumento sustentado, representando uma preocupação constante para as autoridades, mas geralmente é uma das mais altas da América Latina, sendo de 23,08 por 100.000 habitantes em 2022. Reconhecendo que o suicídio é um fenómeno multifatorial grave, vários estudos têm investigado a possível correlação entre a presença de lítio na água encanada e as taxas de suicídio; observa-se uma relação inversa, o que permitiria considerá-lo como um possível protetor do comportamento suicida. O presente estudo visa abordar esta correlação nos departamentos de Rocha e Montevidéu no Uruguai. Os resultados obtidos não são conclusivos. Quanto às concentrações de litio presentes na água corrente, são geralmente inferiores às indicadas em outros estudos como protetoras (30 μ/L). É necessário aprofundar esta área de discussão como em outras linhas de pesquisa, e obter um diagnóstico mais detalhado deste fenômeno complexo e significativo.

Resumo Introdução: A prevalência da infeção pelo vírus da imunodeficiência humana (VIH) parece haver estabilizado nos 0,7%, enquanto em alguns países continua a aumentar. Durante muitos anos estava apenas associada ao continente africano e a populações específicas, mas atualmente constata-se um aumento de incidência nos países desenvolvidos. Esta infeção pode ser assintomática ou ter sintomas inespecíficos. Estes dependem do estádio da doença, da carga viral ou do estado imune do hospedeiro. Este caso mostra o desafio do diagnóstico de VIH, relatando uma forma de apresentação sintomática rara. Descrição do caso: Homem de 21 anos de idade, de nacionalidade angolana, que recorre à consulta aberta nos cuidados de saúde primários por quedas frequentes no último mês associadas a sensação de falta de força nos membros inferiores. À avaliação física constata-se uma discreta diminuição global da força nas quatro extremidades, com maior tradução no membro superior esquerdo. Nega práticas sexuais de risco ou consumo de drogas parenterais. Após realização de estudo analítico, estudo eletromiográfico e tomografia computorizada crânio-encefálica, da coluna cervical e lombar, constata-se um resultado positivo para a infeção por VIH como a causa desencadeante da sintomatologia apresentada. Comentário: O que inicialmente pareciam sintomas relacionados com uma doença neuromuscular incipiente veio a revelar-se o diagnóstico de uma infeção vírica. Pela inespecificidade dos seus sintomas é importante manter um elevado nível de suspeição para a infeção por VIH. No caso relatado, a neuropatia periférica era a única manifestação desta infeção. Ainda que tenha uma prevalência de até 60% entre os infetados, é rara como manifestação isolada. A sua etiopatologia não é ainda clara, sabe-se que é multifatorial e progressiva. Presentemente o doente encontra-se estável com o início da terapêutica antirretroviral, com melhoria da sintomatologia.

Abstract Introduction: The prevalence of human immunodeficiency virus (HIV) infection seems to be stabilized at 0.7% but in some countries, it continues to rise. For many years it was only associated with the African continent and specific populations, but today there is an increase in the incidence in developed countries. This infection can be asymptomatic or have non-specific symptoms. Those depend on the stage of the disease, the viral load, or the host’s immune status. This case shows how the diagnosis of HIV remains a real challenge, reporting a rare form of symptomatic presentation. Case description: A 21-year-old male, with Angolan nationality, went to primary health care consultation due to frequent falls in the last month associated with a sensation of lack of strength in the lower limbs. During physical evaluation, a discrete global reduction of strength in the four extremities was noted, most markedly in the left upper limb. The patient denied risky sexual practices or parenteral drug consumption. After carrying out complementary analytical studies, an electromyographic study, and computed tomography of the brain, cervical, and lumbar spine, the results came back positive for HIV infection as the cause of the presented symptoms. Comment: What at first seemed to be symptoms related to an incipient neuromuscular disease turned out to be the diagnosis of a viral infection. Due to the nonspecificity of the symptoms, it is important to maintain a high level of suspicion of HIV infection. In this case, peripheral neuropathy was the only manifestation reported. Although it has a prevalence of up to 60% among the infected, it is rare as an isolated sign. Its aetiopathology is still unclear, but it is known to be multifactorial and progressive. Nowadays the patient is stable after the initiation of antiretroviral therapy, with improvement in symptomology.

Abstract Systemic Arterial Hypertension is a multifactorial clinical condition associated with severe outcomes such as stroke and death. One of the main modifiable risk factor for hypertension is an unhealthy diet, often characterized by the consumption of ultraprocessed foods such as sweetened beverages. We aimed to investigate the relationship between the consumption of sweetened beverages, both sugar-sweetened and artificially sweetened, and the prevalence of hypertension in adults. A cross-sectional, household, population-based study with 1,162 adults from two Brazilian cities were carried out. The consumption of food groups and sweetened beverages was obtained by food frequency questionnaire and other data were self-reported. Weight, height, and waist circumference were measured. The association between sweetened beverages consumption and hypertension was analyzed using Poisson regression models, expressed as Prevalence Ratio. The prevalence of hypertension was 16.7%, with no significant difference between genders. The prevalence of consumption of sweetened beverages was 70.3% in men and 54.6% in women, being significantly higher in men. Women who consumed sugar-sweetened and artificially sweetened beverages 6 to 7 days per week had 92% higher prevalence of hypertension compared to those who did not consume or consumed at a lower frequency. Furthermore, women who consumed artificially sweetened beverages at least 1 time per week had 3.36 times higher prevalence of hypertension. The habitual consumption of sweetened beverages may be an important risk factor for hypertension, especially the consumption of diet beverages, which are often marketed as healthier than sugar-sweetened beverages.

Resumen La Hipertensión Arterial Sistémica es una condición clínica multifactorial asociada a resultados graves como el ictus y la muerte. Uno de los principales factores de riesgo modificables de la hipertensión es una dieta poco saludable, a menudo caracterizada por el consumo de alimentos ultraprocesados como las bebidas endulzadas. Nuestro objetivo fue investigar la relación entre el consumo de bebidas endulzadas, tanto azucaradas como edulcoradas artificialmente, y la prevalencia de hipertensión en adultos. Se realizó un estudio transversal, domiciliario y poblacional con 1,162 adultos de dos ciudades brasileñas. El consumo de grupos de alimentos y bebidas endulzadas se obtuvo mediante cuestionario de frecuencia de alimentos y los demás datos fueron autoinformados. Se midieron el peso, la talla y el perímetro de la cintura. La asociación entre el consumo de bebidas endulzadas y la hipertensión se analizó mediante modelos de regresión de Poisson, expresados como Ratio de Prevalencia. La prevalencia de hipertensión fue del 16,7%, sin diferencias significativas entre géneros. La prevalencia de consumo de bebidas endulzadas fue del 70,3% en los hombres y del 54,6% en las mujeres, siendo significativamente mayor en los hombres. Las mujeres que consumían bebidas azucaradas y edulcoradas artificialmente entre 6 y 7 días a la semana tenían 92% mayor prevalencia de hipertensión que las que no consumían o consumían con una frecuencia menor. Además, las mujeres que consumían bebidas edulcoradas al menos 1 vez por semana tenían una prevalencia de hipertensión 3,36 veces mayor. Así pues, el consumo habitual de bebidas endulzadas puede ser un importante factor de riesgo de hipertensión, especialmente el consumo de bebidas dietéticas, que a menudo se comercializan como más saludables que las bebidas azucaradas.

SYNOPSIS The large scale of cave mines leads to many challenges, including operational logistics and geomechanics design. In current practice, pillar stability assessment relies almost exclusively on stress analysis. However, stability is also affected by other factors including those related to operational aspects of the mining method, the effects of which are difficult to account for during the design stages. In this paper we present a case study of the application of a machine learning approach to evaluate the influence of these operational factors on pillar stability at the Chuquicamata underground cave mine in northern Chile. Due to the likely multi-factorial damage process leading to collapses and considering the different pillar conditions, a tree-based machine learning method was used and analysed to improve the understanding of the relative importance of the various contributing factors. Unlike stress analysis methods, it does not require any a priori knowledge of failure mechanisms, nor the calibration of associated controlling parameters. The proposed random forest model predicted pillar collapses with 80% accuracy despite limited samples to model from. The main contributing factors to collapses were found to be related to available pillar volume, cave front geometry, and time under abutment stress conditions. The effects and interactions of such factors were also studied, showing that careful and improved control over operational conditions can significantly reduce the likelihood of pillar collapses. These conclusions could not have been obtained from stress analysis alone, illustrating the complementary nature of conventional stress analysis and machine learning approaches.

■ ABSTRACT Introduction: Facial aging is a gradual, complex, and multifactorial process. It is the result of changes in the quality, volume, and positioning of tissues. Plastic surgeons have modified their approach to facial rejuvenation surgery, opting for the subaponeurotic plane (SMAS). The objective of this study is to analyze 100 cases of patients operated on using the deep SMAS technique, evaluating its applicability and effectiveness. Method: 100 patients were evaluated, undergoing facial plastic surgery using the deep SMAS technique - “Deep Smas”, and followed up for 6 months. Patient satisfaction, number of complications, number of reoperations, risks, and advantages of the technique were observed. Results: 100 patients were operated on over 3 years. Age ranged from 41 to 79 years, with 95% being female. The complications were 8 cases (8%) of injuries to branches of the facial nerve, of which 4 cases of zygomatic injury, 3 cases of mandibular injury, and 1 case of buccal injury; there was 1 case (1%) of post-auricular keloid; 1 case (1%) of hematoma. Regarding surgical revisions, there were 8 cases (8%) of surgical completion due to patient dissatisfaction. There were 15% of nerve injuries between the 1st and 40th surgery, 5% between the 41st and 80th, and no injuries between the 81st and 100th patient. Conclusion: Deep facial lifting or subSMAS has proven to be effective, providing good aesthetic results. It has a low recurrence rate and low morbidity rate; however, it requires a long learning curve.

ABSTRACT Introduction: Talent detection is a dynamic and multifactorial process that must start at school. Objective: Create a mathematical model for evaluating the sporting potential of schoolchildren for athletics in speed, throwing, and endurance events and to test its psychometric properties. Methods: 2871 schoolchildren of both sexes, from 11 to 17 years old, from a military school participated. Between 2015 and 2019, students were submitted to a multidimensional battery of tests containing anthropometric, physical-motor, psychological, socio-environmental, maturational, and performance indicators. In addition, ten teachers evaluated the students regarding the intangibles aspects of their sporting potential and the expectation of future success during this period. Adopting analytical and heuristic procedures, the Gold Score Athletics was created – linear, hybrid (tests + coaches´ eye), and weighted index, according to each indicator's importance, depending on the event type. Results: In the model validation sample (n = 1384), 13.9%, 16.6%, and 11.7% of boys and 10.9%, 10.1%, and 9.1% of girls were classified as high potential (Gold Score ≥ 60) for speed, throwing and endurance events, respectively. Internal consistency (r = 0.76 to 0.82) and diagnostic stability were high (r = 0.72 to 0.81). The Gold Score Athletics for sprinters, throwers, and long-distance runners, both for boys and girls, was higher in students selected for a national competition when compared to those not selected (p < 0.001; d: 0.95 a 1.44) – construct validity – and higher in medalists in an athletics competition, held two years after diagnosis, when compared to non-medalists (p < 0.05; d: 0.62 a 1.87) – predictive validity. Conclusion: The Gold Score Athletics is a valid and reliable scientific model for evaluating the sport's potential of schoolchildren, being useful in the talents detection for Athletics. Level of Evidence II; Diagnostic study.

RESUMEN Introducción: La detección de talentos es un proceso dinámico y multifactorial que debe iniciarse en la escuela. Objetivo: Crear un modelo matemático para evaluar el potencial deportivo de escolares para pruebas de velocidad, lanzamiento y resistencia en atletismo, y probar sus propiedades psicométricas. Métodos: Participaron 2871 escolares de ambos sexos de 11 a 17 años de una escuela militar. Los estudiantes fueron sometidos a una batería de pruebas multidimensionales, que contenían indicadores antropométricos, físico-motores, psicológicos, socioambientales, madurativos y de desempeño. 10 docentes evaluaron a los alumnos sobre los aspectos intangibles del potencial deportivo y la expectativa de éxito futuro. Adoptando procedimientos analíticos y heurísticos, se creó el Gold Score Athletics, índice lineal, híbrido (pruebas + mirada del profesor) y ponderado, según la importancia de cada indicador según el tipo de prueba. Resultados: En la muestra de validación del modelo (n = 1384), el 13,9%, 16,6% y 11,7% de los niños y el 10,9%, 10,1% y 9,1% de las niñas fueron clasificados como de alto potencial (Gold Score ≥ 60) en velocidad, lanzamiento y eventos de resistencia. La consistencia interna (r = 0,76 a 0,82) y la estabilidad diagnóstica fueron altas (r = 0,72 a 0,81). El Gold Score Athletics para velocistas, lanzadores y corredores de fondo, para ambos sexos, fue mayor en los estudiantes seleccionados para una competición nacional en comparación con los no seleccionados (p < 0.001; d: 0,95 a 1,44) – validez del constructo – y mayor en medallistas en una competición de atletismo, realizada dos años después del diagnóstico, en comparación con los no medallistas (p < 0,05; d: 0,62 a 1,87) – validez predictiva. Conclusión: El Gold Score Athletics es un modelo científico válido y fiable para evaluar el potencial deportivo de los escolares, siendo útil en la detección de talentos para el Atletismo.

ABSTRACT Purpose: Dry eye disease is a multifactorial disease that is very common in clinical ophthalmic practice. The use of validated dry eye questionnaires makes it possible to screen this disease in the general population and assess the prevalence of symptoms and frequency of diagnosis, allowing early and appropriate treatment for this condition. The 5-Item Dry Eye Questionnaire (DEQ-5) is a tool that is used to assess the frequency and intensity of ocular discomfort and dryness and the frequency of tearing, which has already been validated in English and Spanish, but not in Portuguese. The aim of this study is to translate and validate the DEQ-5 to Portuguese. Methods: The DEQ-5 was used, consisting of five simple and direct questions: two questions for ocular discomfort, two for ocular dryness, and one for tearing. The initial translation of the English version of the questionnaire into Portuguese was conducted by two Portuguese native-speaking translators, followed by an evaluation and compilation of a single version by an interdisciplinary committee of the translated versions. Furthermore, this version was translated back into English by two individuals whose first language was English, followed by the evaluation and comparison with the original version in English by the same interdisciplinary committee. Afterwards, the final version of the questionnaire was administered to 31 volunteers at two different times. Results: The interobserver reliability of the five questions ranged from 0.584-0.813, and the Pearson correlation from 0.755-0.935, with a p-value of <0.0001. Internal consistency was α=0.887. All questions had moderate to high agreement. Conclusions: The statistical analysis of the collected data found excellent concordance rates (moderate to high for all analyzed questions), allowing the use of the Portuguese version of DEQ-5 in research as a screening test for dry eye disease and tool used to monitor the symptoms.

RESUMO Ojetivos: O olho seco é uma doença multifatorial, muito comum na prática clínica oftalmológica. A utilização de questionários validados de sintomas de olho seco permite rastrear de maneira mais objetiva essa doença na população geral, avaliar a prevalência dos sintomas e frequência de diagnóstico, permitindo o tratamento precoce e adequado dessa condição. O 5-Item Dry Eye Questionnaire (DEQ-5) é um questionário em inglês que avalia a frequência e a intensidade do desconforto e ressecamento ocular e a frequência do lacrimejamento, já validado no inglês e espanhol, porém não no português até o presente momento. O objetivo deste estudo foi traduzir e validar o questionário DEQ-5 para a língua portuguesa. Métodos: Foi utilizado o questionário DEQ-5, composto por 5 perguntas simples e diretas - 2 relacionadas ao desconforto ocular, 2 ao ressecamento ocular e 1 ao lacrimejamento. Foi realizada a tradução inicial da versão em inglês para o português por dois tradutores de língua materna portuguesa, seguido de uma avaliação e compilação de uma versão única por um comitê interdisciplinar das versões traduzidas. Em seguida, tal versão foi traduzida de volta para o inglês por 2 indivíduos que possuíam o inglês como primeira língua, seguido de avaliação e comparação com a versão original em língua inglesa pelo mesmo comitê interdisciplinar. Após, a versão final do questionário foi aplicada em 31 voluntários em dois momentos differentes.

BACKGROUND: Meibomian gland dysfunction (MGD) is one of the most encountered diseases in the clinical practice but appears to be underappreciated as it does not cause blindness. Meibomian gland dysfunction is a multifactorial and complex disorder of the ocular surface. AIM: This study aims to evaluate the characteristics of the meibomian glands in individuals living with HIV and AIDS undergoing antiretroviral therapy. SETTING: The study was conducted at the antiretroviral (ARV) clinic, Mankweng Hospital. METHODS: This was a prospective study conducted with 37 HIV and AIDS participants and 20 healthy controls. All participants were assessed using the Ocular Surface Diseases Index (OSDI) score and, tear break-up time and lid margin regularity (using the slit-lamp biomicroscopy). The loss of the meibomian glands was evaluated using the Marx's line. For this study, this line represented a clinical parameter of meibomian function. RESULTS: The OSDI score was significantly higher in the HIV and AIDS group than that of the control participants (39.95 ± 18.65 and 13.00 ± 9.09, respectively, P < 0.05). The tear breakup time (TBUT) for the HIV and AIDS study group was lower than that of the control group (7.95 ± 3.54 and 9.90 ± 3.70, respectively, P < 0.05). The HIV and AIDS participants showed greater meibomian gland loss relative to the healthy controls (9.30 ± 4.97 and 5.70 ± 2.1, P < 0.05. CONCLUSION: The loss of eyelid meibomian glands is common in people living with HIV and AIDS in comparison with healthy controls. CONTRIBUTION: Although there is a decrease in sight-threatening complications in the era of ARVs, ocular surface disorders (OSD) are still commonly found, which may reduce the quality of life of HIV and AIDS individuals.

Summary: Bioremediation with humic substances is one of the recent and promising techniques for the restoration of soils contaminated by hydrocarbons, but little information is available on its behavior in different types of soil. For these reasons, this research aimed to evaluate the removal of total petroleum hydrocarbons (HTP) in three types of soil with different textures (S1, S2 and S3) and treated with organic vermicompost amendments (cocoa husks, Theobroma cacao; rice, Oriza sativa; sugarcane bagasse, Saccharum officinarum; cow manure) and commercial humic substances (potassium humate). A randomized multifactorial experimental design (3 × 3 × 2) was proposed, which consisted of the type of soil, organic amendment (without vermicompost, with organic vermicompost, commercial humic substances) and microbial load (with microorganisms, without microorganisms). The results were analyzed using the ANOVA-Tukey tests in the Statgraphics CenturionTM V.18 program (α = 0.05) in order to evaluate significant differences between treatments. The results show that S2 with the addition of organic matter had the highest removal (86% of HTP) after 60 days of incubation, compared to the treatment with commercial humic substances, which are related to the low bioavailability of the microorganisms. This behavior was also observed in S3 with a TPH percentage removal of 77.52 and 63.4% for S1. Finally, the cell growth rate was better in S2 with commercial humic substances. An average growth of 94 × 104 CFU g-1 of soil was obtained during the 60 days of evaluation of the experiment, and a maximum of 98×105 CFU g-1 of soil in the 45 days of treatment. To conclude, the use of vermicompost is adequate for clayey soils, since the degradation rates are higher in them. In addition, they represent a cheaper alternative to synthetic treatments and revaluation of organic waste.

Resumen: La biorremediación utilizando sustancias húmicas es una de las técnicas recientes y prometedoras para la restauración de suelos contaminados por hidrocarburos, pero existe poca información sobre su comportamiento en los diversos tipos de suelo. Por estas razones, esta investigación tuvo como objetivo evaluar la remoción de hidrocarburos totales del petróleo o HTP en tres suelos con diferentes texturas (S1, S2 y S3) y tratados con enmiendas orgánicas de vermicomposta (cascarillas de cacao, Theobroma cacao; arroz, Oriza sativa; bagazo de caña, Saccharum officinarum; estiércol de vaca) y sustancias húmicas comerciales (humato de potasio). Se planteó un diseño experimental multifactorial aleatorio (3 × 3 × 2), constituido por tipo de suelo, enmienda orgánica (sin vermicomposta, con vermicomposta orgánica, con sustancias húmicas comerciales), y carga microbiana (con microorganismos, sin microorganismos). Los resultados fueron analizados mediante las pruebas ANOVA-Tukey en el programa Statgraphics Centurion TM V.18 (α = 0.05) con el fin de evaluar diferencias significativas entre los tratamientos. Los resultados muestran que S2 con vermicomposta orgánica tuvo la mayor remoción (86% de HTP) luego de 60 días de incubación, en comparación con el tratamiento con sustancias húmicas comerciales, relacionándose con la baja biodisponibilidad de microorganismos. Este comportamiento también se observó en S3, el cual tuvo un porcentaje de remoción de HTP de 77.52 y 63.4%. Finalmente, la tasa de crecimiento celular fue mejor en S2 con sustancias húmicas comerciales. Se obtuvo un crecimiento promedio de 94×104 UFC g-1 de suelo durante los 60 días de evaluación del experimento, y un máximo de 98×105 UFC g-1 de suelo a los 45 días de tratamiento. Se concluye que el uso de vermicomposta es adecuada para suelos arcillosos, ya que las tasas de degradación son mayores en ellos. Además, representan una alternativa de menor costo que los tratamientos sintéticos y de revalorización de residuos orgánicos.

Resumen Antecedentes: La obesidad es un trastorno multifactorial caracterizado por un aumento en la adiposidad corporal, de amplia prevalencia en nuestro país, a cualquier edad y ligada a grandes consecuencias adversas, incluyendo el desarrollo de cardiopatías. Los programas de rehabilitación cardiaca (RC) son intervenciones interdisciplinarias encaminadas no solo a restaurar la funcionalidad perdida de los pacientes que han sufrido un desenlace cardiovascular, sino también a corregir aquellos factores de riesgo que lo propiciaron y que interfieren en los resultados adaptativos del mismo. La obesidad contribuye a perpetuar el riesgo de cardiopatía y suele ser resistente a las modificaciones del estilo de vida de manera convencional. Objetivo: Establecer pautas en el reconocimiento de la obesidad con directrices de atención al paciente con cardiopatía dentro de los programas de RC y su abordaje interdisciplinario. Método: A través de una extensiva revisión bibliográfica y después de una discusión interdisciplinaria, se elaboró el presente documento para fijar una postura sobre el abordaje de la obesidad en el contexto de los programas de RC en pacientes con cardiopatía. Resultados y conclusiones: Nuestra Sociedad reconoce el abordaje interdisciplinario de los pacientes con obesidad y cardiopatía en su prevención primaria y secundaria, insta a la precisión en su diagnóstico y valoración, y recomienda que su eje primario debe estar basado en primera instancia en las modificaciones del estilo de vida (entrenamiento físico, atención nutricional e intervención psicoemocional), en tanto que la terapia farmacológica y la cirugía bariátrica pudieran ser coadyuvantes en la optimización de los resultados en pacientes selectos.

Abstract Background: Obesity is a multifactorial disorder characterized by increased body adiposity with a wide prevalence in our country, at any age, and linked to major adverse consequences, including the development of heart disease. Cardiac rehabilitation (CR) programs are interdisciplinary interventions aimed not only at restoring the lost functionality of patients who have suffered a cardiovascular outcome, but also at correcting those risk factors that led to it and that interfere with its adaptive results. Obesity contributes to perpetuating heart disease risk and is often resistant to conventional lifestyle modifications. Objective: Establish guidelines in the recognition of obesity with care guidelines for patients with heart disease within CR programs and their interdisciplinary approach. Method: Through an extensive bibliographical review and after an interdisciplinary discussion, this document was prepared to establish a position on the approach to obesity in the context of CR programs in patients with heart disease. Results and conclusions: Our Society recognizes the interdisciplinary approach of our patients with obesity and heart disease in its primary and secondary prevention, urges precision in its diagnosis and assessment, recommends that its primary axis must be based in the first instance on lifestyle modifications (physical training, nutritional care and psycho-emotional intervention), while pharmacological therapy and bariatric surgery could be coadjuvants in optimizing the results in selected patients.

Abstract: Introduction: In Uruguay, breast cancer (BC) ranks first in incidence and mortality from cancer in women. It is a multifactorial disease that is related to genetic inheritance, estrogenic hormonal history, lifestyle, environmental and cultural factors. Objectives: to investigate the clinicopathological characteristics of patients with BC diagnosed at the Hospital de Clínicas and to evaluate the overall overall survival (SVG) and according to the biological subtype. Metodology: data related to the clinicopathological characteristics and the evolution of patients treated for BC in the period between January 1, 2011 and December 31, 2020 assisted in the Mastology Unit of the Hospital de Clínicas were collected. Overall survival (SVG) was calculated for all patients, globally, and according to biological subtype. Results: 390 patients were included. The clinicopathological characteristics were: ductal carcinoma: 83%, stage: in situ (1.8%), I (27.7%), II (29.7%), III (23.6%), IV (12.6%). Regarding the biological profile: 235 tumors (60.3%) were HR+ HER 2−, 88 tumors (22.6%) were HER2 +, while another 41 tumors (10.5%) were classified as triple negative (TN). The SVG for all the patients had a median of 92 months. SVG rates at 2 and 5 years were 92% and 64% for luminals; in TN the 24-month survival rate was 69%, being 53.3% at 5 years and in HER2 + 76.6% and 67.3% respectively. Conclusions: Most of the tumors were diagnosed in early stages, these data being consistent with those reported in studies carried out at the national level. The frequency of ER/RP+ tumors was somewhat lower than that reported in previous studies (70%) at the national level, while that of HER 2 + TN tumors was similar to that reported in European, North American and Latin American studies where the prevalence found is 20%

Resumen Introducción: entre los retos epidemiológicos de la sociedad española de la primera mitad del siglo XX, destacaba el problema de la malnutrición. Aunque eran el hambre y la desnutrición las formas más prevalentes, el sobrepeso y la obesidad empezaban a emerger entre las clases acomodadas. En todos los casos y, sobre todo, en el escenario de la sobrealimentación, la cuestión no era tanto económica como de falta de conocimientos. Por esta razón, para los higienistas eran fundamentales la divulgación y la educación en alimentación y nutrición. En este ámbito, destaca la aportación del endocrinólogo catalán Jesús Noguer Moré (1903-1983). El objetivo es analizar los trabajos que dedicó a la obesidad. Material y método: análisis bibliográfico de las obras de Jesús Noguer Moré. Resultados y conclusión: consideraba la obesidad una patología de etiología multifactorial con graves consecuencias para la morbimortalidad. Intervendrían desde la genética hasta patologías previas, pasando por hábitos alimentarios y de vida inadecuados. Su abordaje terapéutico debía basarse en restricciones calóricas y actividad física. Subrayaba el papel de determinados tipos de actividades familiares o profesionales en el fomento del sobrepeso y la obesidad. En materia preventiva, resaltaba la importancia de las prácticas culinarias y gastronómicas, al mismo tiempo que hacía recaer la responsabilidad de las mismas en las amas de casa, un discurso de género que llevó a Noguer a situar a las mujeres como colectivo diana de su acción divulgadora y donde estuvo muy presente el ideal de belleza femenina vigente en el periodo de entreguerras.

Abstract Introduction: among the epidemiological challenges facing Spanish society in the first half of the 20th century, the problem of malnutrition stood out. Although hunger and malnutrition were the most prevalent forms, overweight and obesity were beginning to emerge, particularly among the wealthier classes. In all cases, and especially in the overnutrition situation, the issue was not so much economic as one of lack of knowledge. For this reason, for the hygienists, dissemination and education in food and nutrition was fundamental. In this field, the contribution of the Catalan endocrinologist Jesús Noguer Moré (1903-1983) stands out. The aim is to analyze the work he devoted to obesity. Material and methods: bibliographic analysis of the works of Jesús Noguer Moré. Results and conclusion: he considered obesity as a pathology of multifactorial etiology with serious consequences for morbidity and mortality. It would involve everything from genetics to previous pathologies, as well as inadequate dietary and lifestyle habits. Its therapeutic approach should be based on calorie restriction and physical activity. He underlined the role of certain types of family or professional activities in promoting overweight and obesity. In terms of prevention, he emphasized the importance of culinary and gastronomic practices, while at the same time placing the responsibility for these practices on housewives. A gender discourse that led Noguer to place women as the target group for his dissemination activities and where the ideal of feminine beauty in force in the inter-war period was very much present.
