Percepção do peso corporal e dificuldades encontradas pelas pessoas com deficiência visual na aquisição, na preparação e no consumo dos alimentos / Perception of body weight and difficulties encounteredby people with visual impairment in acquiring, preparing and consuming food

Objetivo: investigar a percepção do peso corporal e as dificuldades encontradas pelas pessoas com deficiência visual na aquisição, na preparação e no consumo dos alimentos. Metodologia: estudo observacional transversal, com adultos e idosos com deficiência visual em Pelotas/RS, realizado no período de abril a maio de 2023. Foi utilizado um questionário composto de 42 itens. Os dados coletados foram analisados por análise descritiva e analítica, e apresentados como média ± desvio padrão ou percentual. Resultados: a amostra contou com 20 pessoas, predominantemente do sexo feminino e idosas. Em relação ao consumo alimentar, 50% dos participantes consomem feijão, 75% frutas e hortaliças, 50% bebidas adoçadas, biscoitos recheados e doces. Referente à percepção do peso corporal, percebeu-se que a maior parte do grupo sente que está acima do peso adequado e se sentem "insatisfeitos(as)". Sobre as dificuldades encontradas, 85% dos participantes relataram dificuldade extrema para identificar a validade dos alimentos, 70% para comprar alimentos frescos e perecíveis e 40% para usar a faca para cortar e descascar os alimentos. Conclusão: verificou-se que a maior parte do grupo sente que está acima do peso adequado e estão "insatisfeitos(as)" em relação ao peso corporal. Além disso, dependem de outra pessoa para escolher os alimentos a serem comprados, saber o prazo de validade, preparar alimentos que precisam ser porcionados, servir refeições no prato, cortar carnes, descascar vegetais e frutas, utilizar faca, entre outros. Esta dependência pode influenciar diretamente no seu consumo alimentar quando essas pessoas se encontram sozinhas, optando por consumir alimentos industrializados de fácil preparo ou prontos.

Objective: to investigate the perception of body weight and the difficulties encountered by people with visual impairments in acquiring, preparing and consuming food. Methodology: cross-sectional observational study, with adults and elderly people with visual impairment in Pelotas/RS, carried out from April to May 2023. A questionnaire composed of 42 items was used. The collected data were analyzed using descriptive and analytical analysis, and presented as mean ± standard deviation or percentage. Results: the sample included 20 people, predominantly female and elderly. Regarding food consumption, 50% of participants consume beans, 75% fruits and vegetables, 50% sweetened drinks, stuffed cookies and sweets. Regarding the perception of body weight, it was noticed that the majority of the group feels that they are overweight and feel "dissatisfied". Regarding the difficulties encountered, 85% of participants reported extreme difficulty in identifying the expiration date of food, 70% in purchasing fresh and perishable foods and 40% in using a knife to cut and peel food. Conclusion: it was found that the majority of the group feels that they are overweight and are "dissatisfied" with their body weight. Furthermore, they depend on someone else to choose the food to be purchased, know the expiration date, prepare food that needs to be portioned, serve meals on the plate, cut meat, peel vegetables and fruits, use a knife, among others. This dependence can directly influence their food consumption when these people are alone, choosing to consume easily prepared or ready-made processed foods.

Tratamiento de la alergia a la proteína de la leche de vaca. Consenso interdisciplinario de expertos / Cow's milk allergy treatment. An expert consensus

El tratamiento de la alergia a las proteínas de la leche de vaca se basa en la eliminación completa de las proteínas de leche de vaca de la dieta del niño y de la madre en los que reciben leche materna. Para lograr la remisión de los síntomas y la tolerancia futura, la exclusión debe ser total. En los niños que reciben fórmula, esta deberá tener hidrolizado extenso de proteínas en las formas leves o moderadas, mientras que aquellas a base de aminoácidos se reservan para los casos más graves. El tiempo de tratamiento, la adquisición de tolerancia y el momento para la prueba de provocación oral van a variar según el cuadro clínico, el mecanismo inmunológico implicado y la edad del paciente. El objetivo de este consenso ha sido reflejar el conocimiento actualizado junto con la experiencia de neonatólogos, pediatras, especialistas en alergia, nutrición y gastroenterología.

The treatment of cow's milk protein allergy is based on the complete elimination of cow's milk protein from the diet. To achieve remission of symptoms and future tolerance, exclusion must be total. In formula fed infants the extensively hydrolysed formula is the most appropriate option in mild or moderate forms, while those based on amino acids are reserved for the most severe cases. The treatment time, the acquisition of tolerance and the moment for the oral provocation test will vary according to the clinical picture, the immunological mechanism involved and the age of the patient. The aim of this consensus has been to reflect the updated knowledge together with the experience of neonatologists, pediatricians, experts in allergy, nutrition and gastroenterology

Introduction. Etymologically the word ileus comes from the Greek eileos, which means rolling or turning. It is described as the temporary delay of gastrointestinal motility. It is recognized worldwide that postoperative ileus is one of the main complications after surgery and represents an important problem due to its high healthcare cost. Research has been done regarding the preventive use of physical and pharmacological measures, such as prokinetics, for the management of postoperative ileus.Methods. Clinical-therapeutic, comparative, prospective longitudinal follow-up research, with non-probabilistic convenience sampling, made up of four groups with 25 patients each, treated in the General Surgery Service between May and August 2021. Results. The patients had a mean age of 49.4 ± 19.6 years and 53% were male; 86% of patients had bowel sounds within 24 hours after the operation. The first bowel movement in patients who ingested espresso coffee was 42.6 hours and for those in the American coffee group it was at 43.4 hours compared to 89.4 hours in the control group (p < 0.001). Conclusion. The use of coffee is recommended as a safe and economical measure to start the diet as an alternative to the traditional fashion, becoming an option for the management of postoperative ileus.

Type 2 diabetes mellitus, obesity, cesarean section delivery, and lack of exclusive breastfeeding exposure in patients from the Guadalajara Metropolitan Area, Mexico.

Introduction: Introduction: the combination of cesarean section delivery and limited exposure to full breastfeeding (FBF) in the first six months of life may increase the risk of obesity and diabetes mellitus. This study aimed to establish an association between type 2 diabetes mellitus (T2DM) in adulthood, cesarean section delivery and incomplete full breastfeeding (FBF) in individuals from the metropolitan area of Guadalajara, Mexico. Methodology: this analytical cross-sectional study included patients over 18 years of age with T2DM and normal weight, overweight or obesity, regardless of sex. Informed consent was obtained. Variables encompassed T2DM, type of delivery method, first-year diet, family history, demographic, socioeconomic, and educational characteristics, and anthropometric measurements. For statistical analysis, Student's t test, chi-square tests and odds ratios were employed. Results: the study evaluated 218 patients with an average age of 57.8 years (± 12.7) and an average age at T2DM diagnosis of 46.2 years (± 12.5). FBF (65.6 %) and partial breastfeeding (PBF) (23.8 %) prevailed in the first six months. The average age at T2DM diagnosis was 46.7 years (± 12.1) for vaginally born patients and 30.7 years (± 15.5) for cesarean-born patients (p = 0.001). Cesarean delivery increased obesity risk by nine times in patients with T2DM [OR = 8.9 (CI, 1.05, 75.2), p = 0.02]. Conclusion: prioritizing the limitation of nonmedically justified cesarean section deliveries is crucial to mitigate the risk of obesity and T2DM in adulthood. .

Introducción: Introducción: la combinación de parto por cesárea y exposición limitada a la lactancia materna completa (LMC) en los primeros seis meses de vida puede aumentar el riesgo de obesidad y diabetes mellitus. Este estudio tuvo como objetivo establecer una asociación entre la diabetes mellitus de tipo 2 (DM2) en la edad adulta, el parto por cesárea y la lactancia materna incompleta (LMI) en individuos del área metropolitana de Guadalajara. Metodología: este estudio transversal y analítico incluyó pacientes mayores de 18 años con DM2 y normopeso, sobrepeso u obesidad, independientemente del sexo. Las variables abarcaron la DM2, el tipo de método de parto, la dieta del primer año, los antecedentes familiares, las características demográficas, socioeconómicas y educativas, y las medidas antropométricas. Se utilizaron las pruebas t de Student, chi-cuadrada y odds ratio. Resultados: el estudio evaluó a 218 pacientes con una edad promedio de 57,8 años (± 12,7) y una edad promedio al diagnóstico de DM2 de 46,2 años (± 12,5). En los primeros seis meses prevalecieron la lactancia materna (65,6 %) y la lactancia materna parcial (23,8 %). La edad promedio al diagnóstico de DM2 fue de 46,7 años (± 12,1) para los pacientes nacidos por vía vaginal y de 30,7 años (± 15,5) para los pacientes nacidos por cesárea (p = 0,001). El parto por cesárea aumentó nueve veces el riesgo de obesidad en pacientes con DM2 [OR = 8,9 (IC: 1,05, 75,2), p = 0,02]. Conclusión: es crucial priorizar la limitación de los partos por cesárea no justificados por razones médicas para mitigar el riesgo de obesidad y DM2 en la edad adulta.

Existem diferenças entre homens e mulheres quanto aos fatores associados à ingestão de cálcio? / Are there differences between men and women with respect to the factors associated with calcium intake?

Resumo O objetivo do artigo é verificar se existem diferenças entre os sexos quanto aos fatores que se associam à ingestão de cálcio. Estudo realizado com dados de inquérito de saúde, em amostra de 1.640 indivíduos de 20 anos ou mais residentes no município de Campinas-SP. A ingestão de cálcio foi obtida por meio de um recordatório de 24 horas (R24h) e analisada segundo variáveis sociodemográficas, de comportamentos de saúde, frequência de refeições e índice de massa corporal (IMC); a presença de associações foi verificada por meio de testes de regressão linear múltipla. O perfil de fatores associados à ingestão de cálcio diferiu entre os sexos. A prática de atividade física no contexto de lazer só se associou ao consumo de cálcio no sexo masculino, enquanto cor da pele, tabagismo, renda, excesso de peso e frequência do café da manhã mostraram associação apenas no sexo feminino. Escolaridade e realização de lanches intermediários mostraram-se associadas à ingestão de cálcio em ambos os sexos. A análise aponta segmentos da população feminina e masculina em que a importância da ingestão de cálcio precisa ser mais enfatizada; além disso, alerta para a importância do desenvolvimento de análises de saúde estratificadas por sexo em decorrência de diferentes padrões comportamentais que prevalecem entre os sexos.

Abstract The scope of this article is to verify if there are differences in factors associated with calcium intake between men and women. It is based on a study conducted with data from a health survey in a sample of 1641 individuals aged 20 years or more living in the urban area of the city of Campinas, in the State of São Paulo. Calcium intake was obtained from a 24-hour recall (24hr recall method) and analyzed according to sociodemographic variables, health behavior, frequency of meals and body mass index (BMI). The existence of associations was verified by multiple linear regression tests, and it was detected that the profile of associated factors differed between genders. Physical exercise in the leisure context was only associated with calcium intake in males, while skin color, smoking, income, overweight/obesity, and frequency of having breakfast only revealed an association in females. Schooling and having snacks were associated with calcium intake in both sexes. The analysis of the associated factors indicates segments of the female and male population in which the importance of calcium intake needs to be more closely examined. Furthermore, it highlights the importance of conducting health analyses stratified by sex due to the different behavioral patterns that prevail between the sexes.

Predictors of response to a dietary intervention in patients with irritable bowel syndrome.

BACKGROUND: Different diets have emerged as potential therapeutic options for patients with irritable bowel syndrome (IBS). OBJECTIVE: To identify predictors of improvement after a low-FODMAP, low-starch and low-sucrose diet among patients with IBS. METHODS: We performed a descriptive cross-sectional study including patients with IBS according to Rome IV criteria undertaking a social-media based program with a two-week dietary intervention. Patients completed an online survey before and after the intervention including the presence of intestinal and extra-intestinal symptoms, the IBS-SSS (irritable bowel syndrome symptoms severity scale) and the PHQ-9 (patient health questionnaire-9). Clinical improvement was defined as a decrease of at least 50% in IBS-SSS post dietary intervention. Variables associated with symptomatic response were identified with logistic regression analysis. A clinical score to predict response was created and tested with a with a receiver operating characteristic (ROC) curve analysis. RESULTS: A total of 3583 patients with IBS were included. Mean IBS-SSS before and after dietary intervention was 295.5±52.32 and 240±48.66, respectively (p=0.01); 1178 (32.8%) patients showed clinical improvement. A mean basal IBS-SSS >400 (OR 3.04), chronic headache (OR 1.96), and chronic fatigue (OR 1.81) were significantly associated with symptomatic response. Patients with arthralgia (OR 0.41) and/or fibromyalgia (OR 0.33) were less likely to improve. Each variable received the following individuals scores: IBS-SSS >400: +2, chronic headache: +1.5, chronic fatigue: +1, arthralgia: -1, and fibromyalgia: -1. The ROC curve analysis of the proposed score showed an area under the curve of 0.72 (95% CI 0.69-0.76). A score ≥3 had a sensitivity of 72.64% and specificity of 60.56% for predicting symptomatic improvement. CONCLUSIONS: There are clinical variables that could serve as reliable predictors of response to a low-FODMAP, low-sucrose, low-starch diet among patients with IBS. Further research is needed to understand the link between the presence of extra-intestinal symptoms and clinical improvement after dietary interventions for IBS.

Manejo quirúrgico en el estado epiléptico superrefractario / Surgical management in Super-refractory epilepticus status

Resumen Introducción: El estado epiléptico refractario (EER) constituye una emergencia médica grave, donde la crisis no cede a pesar del tratamiento farmacológico convencional. Se describe como estado epiléptico superrefractario (EESR) la continua presencia de episodios con una duración de 24 horas o más. Este reporte de caso detalla la complejidad en el manejo y explora un enfoque multidisciplinario. Presentación del caso: Paciente masculino de 32 años con antecedente de epilepsia focal secundaria a traumatismo craneoencefálico en la niñez, quien ingresó en contexto de EESR, el cual recibió coma barbitúrico, plasmaféresis y dieta cetogénica. En los exámenes, la resonancia magnética reveló una lesión en la región frontotemporal insular derecha; en la tomografía por emisión de positrones se observaron zonas de hipermetabolismo y en el videoelectroencefalograma una continua actividad epileptiforme. Se optó por la cirugía paliativa, logrando la resolución exitosa del EESR y una clasificación Engels IA a los 14 meses. Discusión: El EESR es un evento neurológico crítico con pronóstico reservado y opciones terapéuticas desafiantes. Se describen opciones terapéuticas desde anticonvulsivantes, inmunoterapia y cirugía, donde el abordaje quirúrgico emerge como una opción eficaz, especialmente en casos con lesiones estructurales. La identificación temprana y la terapia adecuada son vitales para prevenir complicaciones. Conclusiones: El EESR representa un desafío crítico con alta carga de morbimortalidad, sin embargo, la cirugía de epilepsia muestra promisorios resultados en el contexto de causa cerebral estructural, responsable de la actividad epileptiforme. Se destaca la importancia de la identificación temprana y el manejo quirúrgico paliativo como opción viable, mejorando la calidad de vida de los pacientes.

Abstract Introduction: Refractory Status Epilepticus (RSE) is a serious medical emergency where the seizure does not subside despite conventional pharmacological treatment. The continuous presence of episodes lasting 24 hours or more is described as super-refractory status epilepticus (SRSE). This case report details the complex in teraphy management and explores a multidisciplinary approach. Case presentation: A 32-year-old male with a history of focal epilepsy secondary to head trauma in childhood. Enters emergency with a RSE episode. Barbiturate coma, plasmapheresis and ketogenic diet were administered. The Magnetic Resonance Imaging revealed a lesion in the right fronto-temporo-insular cortex, areas of hypermetabolism on Positron Emission Tomography and continuous epileptiform activity on video-electroencephalogram. Palliative surgery was chosen, achieving successful resolution of the SRSE and Engel Scale IA classification at 14 months of follow up. Discussion: The SRSE is a critical neurological event with a guarded prognosis and complex therapeutic options. Therapeutic options are described from anticonvulsants, immunotherapy and surgery. The surgical approach emerges as an effective option, especially in cases with structural injuries. Early identification and appropriate therapy are vital to prevent complications. Conclusions: SRSE represents a critical challenge with a high burden of morbidity and mortality. However, epilepsy surgery shows promising results in the context of the structural brain cause responsible for epileptiform activity. The importance of early identification and palliative surgical management as a viable option is highlighted, improving the quality of life of patients.

Celiac Disease, A Silent Enemy: A Case Report / Enfermedad celiaca, un enemigo silencioso: a propósito de un caso

Abstract Celiac disease (CD) is an immune-mediated enteropathy with systemic compromise in genetically susceptible individuals, caused by an immune response to ingested gluten. The only therapy for CD is a gluten-free diet (GFD). A case of a 55-year-old woman who reported to the emergency room for early satiety, intolerance to legumes, abdominal distension, and chronic diarrhea, including paresthesias in the upper and lower limbs, was presented. In addition, she described a functional decline due to dyspnea and involuntary weight loss of approximately 20 kilograms in the last 2 years. An esophagogastroduodenoscopy with CD protocol was performed, along with serology for CD, which confirmed the initial diagnostic suspicion. Treatment with a gluten-free diet and nutritional supplementation was indicated, which yielded a significant improvement in the clinical picture.

Resumen La enfermedad celiaca (EC) es una enteropatía inmunomediada con compromiso sistémico en individuos genéticamente susceptibles, causada por una respuesta inmunitaria al gluten ingerido. La única terapia para la EC es una dieta libre de gluten (DLG). Se presenta el caso de una mujer de 55 años que acudió al servicio de urgencias por saciedad precoz, intolerancia a las leguminosas, distensión abdominal y diarrea crónica, además de parestesias en los miembros superiores e inferiores. Adicionalmente, describió una disminución de la clase funcional por disnea y pérdida involuntaria de aproximadamente 20 kilogramos de peso en los últimos 2 años. Se realizó una esofagogastroduodenoscopia con protocolo para EC, junto con serología para la misma, lo cual confirmó la sospecha diagnóstica inicial. Se indicó tratamiento con dieta libre de gluten y suplementación nutricional, que produjo una mejoría significativa del cuadro clínico.

Resumo Fundamento Alcançar as metas nutricionais estabelecidas pelas sociedades científicas é um desafio constante e nem sempre alcançado. Objetivo Investigar a adequação alimentar de indivíduos com doença cardiovascular (DCV), participantes do Programa Alimentar Brasileiro Cardioprotetor residentes da região Nordeste do Brasil, segundo as recomendações da Sociedade Brasileira de Cardiologia (SBC). Métodos Análise transversal com dados do estudo de implementação da Dieta Cardioprotetora Brasileira (DICA BR) que avaliou indivíduos com DCV, atendidos em centros especializados em saúde cardiovascular em oito estados do Nordeste. O consumo alimentar foi obtido por recordatório alimentar de 24 horas e a adequação da dieta seguiu as recomendações da SBC. Foram considerados significantes valores de p < 0,05. Resultados Foram estudados 647 pacientes, com média (desvio padrão) de idade de 63,1 (9,4) anos, sendo 50,2% do sexo feminino. Na avaliação da ingestão alimentar, observou-se baixa adequação de carboidratos (52,3%), proteínas (70,9%), lipídios (38,8%) e fibras (22,4%). Observou-se que a maioria das mulheres consumia dieta hipoproteica (59,2%) e idosos tinham maior inadequação no consumo de carboidratos (52,6%). Em relação a ingestão de sódio, os homens apresentaram maior ingestão (72,9%), enquanto os idosos apresentaram redução de 13%. Além disso, foi demonstrado que os homens ingeriam mais fibras (28,1%) e indivíduos com maior escolaridade tinham um consumo elevado de ácidos graxos saturados (70,5%). Conclusões A maioria dos indivíduos não alcançou as metas dietoterápicas preconizadas para prevenção cardiovascular secundária. Os achados do presente estudo reforçam a necessidade de implementação de estratégias estruturadas, a fim de estimular hábitos alimentares saudáveis nesses indivíduos.

Abstract Background Achieving nutritional goals established by scientific societies is a constant challenge and not always achieved. Objective To investigate the dietary adequacy of individuals with cardiovascular disease (CVD), participants in the Cardioprotective Brazilian Food Program residing in the Northeast region of Brazil, according to the recommendations of the Brazilian Society of Cardiology (SBC). Methods Cross-sectional analysis with data from the study implementing the Brazilian Cardioprotective Diet (DICA BR), which evaluated individuals with CVD treated in specialized cardiovascular health centers in eight states in the Northeast region. Food consumption was obtained by 24-hour dietary records and dietary adequacy followed SBC recommendations. Values of p < 0.05 were considered significant. Results 647 patients were studied, with a mean (standard deviation) age of 63.1 (9.4) years, 50.2% of whom were female. When evaluating food intake, a low adequacy of carbohydrates (52.3%), proteins (70.9%), lipids (38.8%), and fiber (22.4%) was observed. It was observed that the majority of women consumed a low-protein diet (59.2%) and the elderly had a greater inadequacy in carbohydrate consumption (52.6%). Regarding sodium intake, men had a higher intake (72.9%), while the elderly showed a 13% reduction. Furthermore, it was shown that men ate more fiber (28.1%) and individuals with higher education had a high consumption of saturated fatty acids (70.5%). Conclusions Most individuals did not achieve the recommended dietary therapy goals for secondary cardiovascular prevention. The findings of the present study reinforce the need to implement structured strategies to encourage healthy eating habits in these individuals.

Effects of glyphosate herbicide ingestion on kidney function in rats on a balanced diet / Efeitos da ingestão do herbicida glifosato na função renal de ratos em uma dieta balanceada

Abstract Introduction: Glyphosate is the most widely used herbicide worldwide and in Brazil. There is currently increasing concern about the effects of glyphosate on human health. The Brazilian Institute for Consumer Protection showed data on the presence of glyphosate in some of Brazil's most consumed ultra-processed products. Currently, regulations on the upper limit for these residues in ultra-processed foods have yet to be established by the National Health Surveillance, and ultra-processed food consumption is independently associated with an increased risk of incident chronic kidney disease. Methods: Since an unbalanced diet can interfere with kidney function, this study aims to investigate the effect of daily intake of 5 mg/kg bw glyphosate in conjunction with a balanced diet and the possible impact on renal function in rats. Kidney function, kidney weight, markers of renal injury, and oxidative stress were evaluated. Results: There was a decrease in kidney weight. The main histopathological alterations in renal tissues were vacuolation in the initial stage and upregulation of the kidney injury marker KIM-1. Renal injury is associated with increased production of reactive oxygen species in mitochondria. Conclusion: This study showed changes in the kidney of rats exposed to a balanced diet with glyphosate, suggesting a potential risk to human kidney. Presumably, ultra-processed food that contain glyphosate can potentiate this risk. The relevance of these results lies in drawing attention to the need to regulate glyphosate concentration in ultra-processed foods in the future.

RESUMO Introdução: O glifosato é o herbicida mais utilizado no mundo e no Brasil. Atualmente, há uma preocupação crescente com os efeitos do glifosato na saúde humana. O Instituto Brasileiro de Defesa do Consumidor apresentou dados sobre a presença de glifosato em alguns dos produtos ultraprocessados mais consumidos no Brasil. Atualmente, as regulamentações sobre o limite máximo desses resíduos em alimentos ultraprocessados ainda não foram estabelecidas pela Vigilância Sanitária Nacional, e o consumo de alimentos ultraprocessados está indepen­dentemente associado a um risco maior de doença renal crônica incidente. Métodos: Como uma dieta desbalanceada pode interferir na função renal, este estudo tem como objetivo investigar o efeito da ingestão diária de 5 mg/kg pc de glifosato em conjunto com uma dieta equilibrada e o possível impacto na função renal em ratos. Foram avaliados função renal, peso dos rins, marcadores de lesão renal e estresse oxidativo. Resultados: Houve redução no peso dos rins. As principais alterações histopatológicas nos tecidos renais foram vacuolização no estágio inicial e regulação positiva do marcador de lesão renal KIM-1. A lesão renal está associada à produção aumentada de espécies reativas de oxigênio nas mitocôndrias. Conclusão: Esse estudo mostrou alterações nos rins de ratos expostos a uma dieta balanceada com glifosato, sugerindo um risco potencial ao rim humano. Presumivelmente, alimentos ultraprocessados que contenham glifosato podem potencializar esse risco. A relevância desses resultados está no fato de chamar a atenção para a necessidade de regulamentar a concentração de glifosato em alimentos ultraprocessados no futuro.

Percepção e satisfação corporal de estudantes universitários vegetarianos / Perception and body satisfaction of vegetarian students / Percepción y satisfacción corporal de los estudiantes vegetarianos

INTRODUÇÃO: A percepção e satisfação corporal têm sido amplamente estudadas em diversos públicos, principalmente em estudantes universitários; porém, existem poucas investigações com vegetarianos, sendo assim, torna-se necessário avaliar se o padrão alimentar vegetariano está relacionado com os fenômenos inerentes à imagem corporal. OBJETIVO: Avaliar a percepção e a satisfação corporal entre estudantes universitários vegetarianos. MÉTODO: Trata-se de um estudo transversal com 123 participantes, no qual foram aplicados o Questionário de Imagem Corporal - BSQ (Body Shape Questionnaire) e a Escala de Silhuetas de Stunkard. RESULTADOS: Os dados mostraram que 86,2% dos participantes eram eutróficos (IMC=22,4±3,3), sendo o score obtido no BSQ foi de 84,6 pontos (±36,0) correspondente à leve insatisfação com a imagem corporal. Cerca de 82,1% dos estudantes se mostravam insatisfeitos com a silhueta, dentre estes, 61,4% desejavam diminuí-la. CONCLUSÃO: O padrão alimentar (ovolactovegetariano, lactovegetariano, vegetariano estrito e vegano) não se relacionou com a insatisfação corporal, mas sim o desejo de ter silhuetas magras que são valorizadas pelo padrão de beleza vigente.

INTRODUCTION: For Body perception and satisfaction have been widely studied among different publics, especially among college students; however, there are few investigations with vegetarians. Therefore, it is necessary to evaluate whether the vegetarian eating pattern is related to the phenomena inherent to body image. OBJECTIVE: To evaluate body perception and body satisfaction among vegetarian college students. METHOD: This is a cross-sectional study with 123 participants, in which the Body Image Questionnaire (BSQ) and the Stunkard Silhouette Scale were applied. RESULTS: The data showed that 86.2% of the participants were eutrophic (BMI=22.4±3.3), and the score obtained in the BSQ was 84.6 points (±36.0) corresponding to a mild dissatisfaction with body image. About 82.1% of the students were dissatisfied with their silhouette, and 61.4% of them wanted to reduce it. CONCLUSION: Dietary patterns (ovolactovegetarian, lactovegetarian, strict vegetarian, and vegan) were not related to body dissatisfaction, but rather the desire to have thin silhouettes that are valued by the prevailing beauty standard.

Impact of memory bias in the dietary estimation of older adults measured through a food frequency questionnaire and weighed food records: A cross-sectional study in older adults and primary caregivers.

Introduction: Introduction: changes in cognitive performance and memory of older adults (OA) can interfere in their reporting their diet. Objective: to evaluate the impact of memory bias in dietary estimation between OA and their primary caregivers (PC) through the food frequency questionnaire (FFQ) for Mexican OA and weighed food records (WFR). Methods: the present analysis uses the estimated dietary information based on the response provided by 51 older adults (OA) and their primary caregivers (PC) from the validation study of the FFQ for Mexicans OA was conducted during lockdowns for COVID-19. The personnel who applied FFQ and WFR were trained with standardized instruments and procedures. The Wilcoxon test was used to compare the intake per day of the foods and food groups, the Spearman correlation coefficient was used to evaluate the grams of intake per day of the food groups, and kappa coefficient was used to compare the level of food items and food groups between OA and PC. Results: in 11 of 14 food groups, no significant differences were observed between the amounts of intake reported by OA and PC. In the groups of dairy products, fruits, vegetables, and legumes, moderate agreement was observed (κ = 0.63 to 0.79), and in the rest of the groups was strong to perfect (κ ≥ 0.80). Correlation of the amount of intake between OA and PC was high in all food groups (r ≥ 0.87). Conclusion: the high correlation and high agreement between the amounts and frequencies of the food groups consumed as reported by the older adults and primary caregivers indicate that the information from both respondents is reliable.

Introducción: Introducción: los cambios cognitivos y la memoria que presentan los adultos mayores (AM) pueden interferir al momento de reportar los alimentos de su dieta. Objetivo: evaluar el impacto del sesgo de memoria en la estimación de la dieta entre AM y sus cuidadores principales (CP) a través del cuestionario de frecuencia de alimentos (CFA) para AM mexicanos y el registro de peso de alimentos (RPA). Métodos: el presente análisis utiliza la información dietética estimada con base en la respuesta proporcionada por 51 adultos mayores (AM) y sus cuidadores principales (CP) del estudio de validación del CFA para AM mexicanos que se realizó durante el confinamiento por COVID-19. El personal que aplicó CFA y RPA fue capacitado con instrumentos y procedimientos estandarizados. Se utilizó prueba de Wilcoxon para comparar la ingesta por día de los alimentos y grupos de alimentos, el coeficiente de correlación de Spearman para evaluar los gramos de ingesta por día de los grupos de alimentos y el coeficiente kappa para comparar el nivel de alimentos y grupos de alimentos entre AM y CP. Resultados: en 11 de 14 grupos de alimentos no se observaron diferencias significativas entre las cantidades de ingesta reportadas por AM y CP. En los grupos de lácteos, frutas, verduras y legumbres se observó concordancia moderada (κ = 0,63 a 0,79), y en el resto de los grupos fue de fuerte a perfecta (κ ≥ 0,80). La correlación de la cantidad de ingesta entre AM y CP fue alta en todos los grupos de alimentos (r ≥ 0,87). Conclusión: La alta correlación y la alta concordancia entre las cantidades y frecuencias de los grupos de alimentos consumidos según lo informado por los adultos mayores y los cuidadores principales indican que la información de ambos encuestados es confiable.

Association of diet quality and body mass index in Mexican adults: a pseudo-panel analysis.

Introduction: Introduction: most studies that analyze the relationship between diet quality and obesity have a cross-sectional design; an alternative with repeated cross-sectional data is a pseudo-panel design. Objective: to estimate the association between trends in dietary patterns, defined by a diet quality index, and body mass index (BMI) of Mexican adults between 2006 and 2016. Methodology: a pseudo-panel analysis was performed using data from cross-sectional surveys: National Health and Nutrition Surveys of Mexico (ENSANUTs) 2006 and 2012 and the Midway National Health and Nutrition Survey 2016 (ENSANUTMC). Cohorts (n = 108) were constructed by grouping adults 20-59 years old by sex (men n = 6,081 and women n = 11,404), education level, and year of birth. The association between diet quality (defined with the Healthy Eating Index-2015) and BMI was estimated using a fixed effects model, adjusting for sociodemographic characteristics. Results: a one-point increase in the proportion of women with high diet quality was associated with 4.1 points lower BMI (p = 0.014) compared with women with low diet quality when excluding sub-reporters of energy, the same association is observed when physical activity is included in the model. No association was found between diet quality and BMI in men, possibly because of the existence of latent classes within sociodemographic strata, therefore diet qualiy is inversely associated with BMI only in some categories of sociodemographic strata. Conclusions: these results contribute to the evidence in the longitudinal analysis between diet and BMI, highlighting the importance of differentiating the population by sex and sociodemographic characteristics. These results are input for public policy creation that promotes improving the quality of the population's diet as part of multisectoral strategies to reduce overweight and obesity in Mexican adults.

Introducción: Introducción: muchos estudios que analizan la relación entre calidad de la dieta y obesidad son transversales; una alternativa con datos transversales repetidos es el diseño de pseudopanel. Objetivo: estimar la asociación entre patrones alimentarios definidos mediante un índice de calidad de la dieta y el índice de masa corporal (IMC) en adultos mexicanos entre 2006 y 2016. Metodología: se realizó un análisis de pseudopanel utilizando datos de las Encuestas Nacionales de Salud y Nutrición de México (ENSANUTs) de 2006 y 2012 y la Encuesta Nacional de Salud y Nutrición de medio camino de 2016 (ENSANUTMC). Se construyeron cohortes (n = 108) agrupando datos de adultos entre 20 y 59 años, por sexo (hombres n = 6,081, mujeres n = 11,404), nivel de escolaridad y año de nacimiento. La asociación entre calidad de la dieta (definida mediante el Índice de Calidad de la Dieta 2015) y el IMC se estimó con un modelo de efectos fijos, ajustado por características sociodemográficas. Resultados: un aumento de 1 punto en la proporción de mujeres con calidad de dieta alta se asoció con 4,1 puntos menos de IMC (p = 0,014) comparado con las mujeres con calidad de dieta baja; al excluir a las subreportadoras de energía, la misma asociación se observó incluyendo la actividad física al modelo. No se encontró asociación entre calidad de dieta e IMC en los hombres, posiblemente debido a la existencia de subgrupos dentro de los estratos sociodemográficos, lo cual hace que la calidad de la dieta esté inversamente asociada al IMC solo en algunas categorías de los estratos. Conclusiones: estos resultados contribuyen a la evidencia longitudinal entre dieta e IMC, destacando la importancia de estratificar por sexo y características sociodemográficas. Los resultados son un ínsumo para crear políticas públicas que promuevan mejorar la calidad de la dieta como parte de estrategias multisectoriales para disminuir el sobrepeso y la obesidad en los adultos mexicanos.

O Treinamento Resistido Atenua a Remodelação Cardíaca Induzida por uma Dieta Hiperlipídica em Roedores: Uma Revisão Sistemática / Resistance Exercise Training Mitigates Cardiac Remodeling Induced by a High-Fat Diet in Rodents: A Systematic Review

Resumo Fundamento A obesidade está associada ao desenvolvimento de doenças cardiovasculares e constitui um grave problema de saúde pública. Em modelos animais, a alimentação com uma dieta hiperlipídica (DH) compromete a estrutura e a função cardíaca e promove estresse oxidativo e apoptose. O treinamento resistido (TR), entretanto, tem sido recomendado como coadjuvante no tratamento de doenças cardiometabólicas, incluindo a obesidade, porque aumenta o gasto energético e estimula a lipólise. Objetivo Na presente revisão sistemática, nosso objetivo foi avaliar os benefícios do TR no coração de ratos e camundongos alimentados com DH. Métodos Foram identificados estudos originais por meio de busca nas bases de dados PubMed, Scopus e Embase de dezembro de 2007 a dezembro de 2022. O presente estudo foi conduzido de acordo com os critérios estabelecidos pelo PRISMA e registrado no PROSPERO (CRD42022369217). O risco de viés e a qualidade metodológica foram avaliados pelo SYRCLE e CAMARADES, respectivamente. Os estudos elegíveis incluíram artigos originais publicados em inglês que avaliaram desfechos cardíacos em roedores submetidos a mais de 4 semanas de TR e controlados por um grupo controle sedentário alimentado com DH (n = 5). Resultados Os resultados mostraram que o TR atenua o estresse oxidativo cardíaco, a inflamação e o estresse do retículo endoplasmático. Também modifica a atividade de marcadores de remodelamento estrutural, apesar de não alterar parâmetros biométricos, parâmetros histomorfométricos ou a função contrátil dos cardiomiócitos. Conclusão Nossos resultados indicam que o TR parcialmente neutraliza o remodelamento cardíaco adverso induzido pela DH, aumentando a atividade dos marcadores de remodelamento estrutural; elevando a biogênese mitocondrial; reduzindo o estresse oxidativo, marcadores inflamatórios e estresse do retículo endoplasmático; e melhorando os parâmetros hemodinâmicos, antropométricos e metabólicos.

Abstract Background Obesity is associated with the development of cardiovascular diseases and is a serious public health problem. In animal models, high-fat diet (HFD) feeding impairs cardiac structure and function and promotes oxidative stress and apoptosis. Resistance exercise training (RT), however, has been recommended as coadjutant in the treatment of cardiometabolic diseases, including obesity, because it increases energy expenditure and stimulates lipolysis. Objective In this systematic review, we aimed to assess the benefits of RT on the heart of rats and mice fed HFD. Methods Original studies were identified by searching PubMed, Scopus, and Embase databases from December 2007 to December 2022. This study was conducted in accordance with the criteria established by PRISMA and registered in PROSPERO (CRD42022369217). The risk of bias and methodological quality was evaluated by SYRCLE and CAMARADES, respectively. Eligible studies included original articles published in English that evaluated cardiac outcomes in rodents submitted to over 4 weeks of RT and controlled by a sedentary, HFD-fed control group (n = 5). Results The results showed that RT mitigates cardiac oxidative stress, inflammation, and endoplasmic reticulum stress. It also modifies the activity of structural remodeling markers, although it does not alter biometric parameters, histomorphometric parameters, or the contractile function of cardiomyocytes. Conclusion Our results indicate that RT partially counteracts the HFD-induced adverse cardiac remodeling by increasing the activity of structural remodeling markers; elevating mitochondrial biogenesis; reducing oxidative stress, inflammatory markers, and endoplasmic reticulum stress; and improving hemodynamic, anthropometric, and metabolic parameters.

Value of precision nutrition in the inflammatory control of systemic lupus erythematosus

Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by the production of autoantibodies directed against endogenous antigens causing various clinical manifestations, chronic inflammation and tissue damage. Although the pathophysiology of SLE remains unknown, it is recognized that genetic, epigenetic, environmental and neuroendocrine factors are involved in the development of the disease and its complications. A notable proportion of patients with SLE also present obesity, and this dysmetabolic profile can cause renal, musculoskeletal and/or respiratory deterioration, fatigue, various pathophysiological alterations and functional deterioration. In this context, precision nutrition emerges as a promising tool in the inflammatory control of SLE, especially in patients with associated obesity. Various studies demonstrate the beneficial influence of balanced dietary patterns in macronutrients with foods rich in fiber, vitamins, minerals, antioxidants and polyphenols on the inflammatory control of SLE and the most diverse pathologies, highlighting the Mediterranean diet and plant-based diets. Finally, the intestinal microbiota may play a relevant role in this clinical scenario, since dysbiosis is associated with inflammatory processes and immune deregulation. It is believed that precision nutrition can modulate inflammatory profiles and immune dysfunctions to ensure better quality of life and metabolic well-being of SLE patients with the support of precision omics technologies.

El lupus eritematoso sistémico (LES) es una enfermedad autoinmune caracterizada por la producción de autoanticuerpos dirigidos contra antígenos endógenos causando diversas manifestaciones clínicas, inflamación crónica y daño tisular. Aunque la fisiopatología del LES sigue siendo desconocida, se reconoce que factores genéticos, epigenéticos, ambientales y neuroendocrinos están implicados en el desarrollo de la enfermedad y sus complicaciones. Una proporción notable de pacientes con LES presenta también obesidad, y este perfil dismetabólico puede producir deterioro renal, musculoesquelético y/o respiratorio, fatiga, diversas alteraciones fisiopatológicas y deterioro funcional. En este contexto, la nutrición de precisión emerge como una herramienta prometedora en el control inflamatorio del LES, especialmente en pacientes con obesidad asociada. Diversos estudios demuestran la influencia beneficiosa de patrones dietéticos equilibrados en macronutrientes con alimentos ricos en fibra, vitaminas, minerales, antioxidantes y polifenoles en el control inflamatorio del LES y de las más diversas patologías, destacando la dieta Mediterránea y las dietas basadas en plantas/vegetales. Por último, la microbiota intestinal puede tener un papel relevante en este escenario clínico, ya que la disbiosis se asocia con procesos inflamatorios y desregulación inmune. Se cree que con la nutrición de precisión se pueden modular los perfiles inflamatorios y las disfunciones inmunitarias para garantizar una mejor calidad de vida y el bienestar metabólico de los pacientes con LES con el apoyo de las tecnologías de precisión ómicas.

Attitudinal factors associated with protein sufficiency in Chilean vegan university students - A pilot study.

Introduction: Introduction: vegan diets are currently an essential topic of discussion because they are recognized as a prototype of a healthy diet but are also associated with deficits in the intake of critical nutrients such as protein. Evaluating the factors that influence the deficit in their intake in vulnerable populations such as university students represents an important topic of interest, considering that this is one of the groups where veganism is most popular. Given this, the present study aimed to determine the degree of protein sufficiency and its associated factors in a sample of Chilean vegan university students. Materials and methods: an exploratory cross-sectional study was conducted on 114 vegan university students who responded to an online survey on academic, attitudinal, clinical, dietary, and sociodemographic variables. Protein intake was calculated, and based on self-reported weight, daily protein adequacy was calculated according to the recommendation of 0.9 g/kg/day. Finally, the association between protein adequacy and previously consulted variables was calculated by determining the odds ratios. Results: only 53.5 % had adequate daily protein intake, which was associated with the length of time respondents had been vegan (OR, 2.86; 95 % CI, 1.07 to 7.34; p < 0.05), use of supplements (OR, 5.24; 95 % CI, 1.17 to 25.2; p < 0.05), and the frequency with which they ate lunch at home (OR, 87.7; 95 % CI, 24.1 to 304; p = 0.000). Conclusion: there needs to be more protein adequacy in the assessed sample. Protein adequacy is associated with the length of time on the vegan diet, frequency of eating lunch away from home, and use of supplements regularly.

Introducción: Introducción: en la actualidad, las dietas veganas representan una importante temática de discusión debido a que son reconocidas como prototipo de régimen saludable pero también se encuentran asociadas a déficits en la ingesta de nutrientes críticos como las proteínas. La evaluación de los factores que influyen en el déficit de su ingesta en poblaciones vulnerables como los estudiantes universitarios representa un importante tema de interés, considerando que es uno de los grupos donde mayor popularidad presenta el veganismo. Frente a esto, el presente estudio tuvo como objetivo determinar el grado de suficiencia proteica y los factores asociados a esta en una muestra de estudiantes universitarios veganos chilenos. Materiales y método: se realizó un estudio de alcance exploratorio de corte transversal en 114 estudiantes universitarios veganos que respondieron a una encuesta online sobre variables académicas, actitudinales, clínicas, dietarias y sociodemográficas. Se calculó la ingesta proteica y, en función del peso autorreportado, se calculó la adecuación proteica diaria de acuerdo con la recomendación de 0,9 g/kg/día. Finalmente se calculó la asociación entre la adecuación proteica y las variables anteriormente consultadas a partir de la determinación de los odds ratios. Resultados: solo un 53,5 % presentaron una ingesta diaria adecuada de proteínas, la cual se asocia al tiempo de antigüedad del veganismo de los encuestados (OR: 2,86; IC 95 %: 1,07 a 7,34; p < 0,05), la utilización de suplementos (OR: 5,24; II 95 %: 1,17 a 25,2; p < 0,05) y la frecuencia con la que almuerzan en el hogar (OR: 87,7; IC 95 %: 24,1 a 304; p = 0,000). Conclusión: existe una importante falta de adecuación proteica en la presente muestra evaluada. La adecuación proteica se asocia con la duración del régimen vegano, la frecuencia de almuerzos fuera de casa y la utilización de suplementos de forma regular.

[Roles within domestic environments in Chile: the "food gatekeeper"]. / Roles dentro de los entornos domésticos en Chile: la "portera alimentaria".

Introduction: Introduction: this project studied the roles played in the food cycle within the domestic environment, revisiting the concept of the "food gatekeeper". Methods: information was obtained from 10 ethnographies and 24 in-depth interviews with people responsible for food tasks in low-income households in Santiago, Chile, during the pandemic. A thematic analysis was conducted from the framework of food environments and gender. Results: the results showed that the time allocated to the food cycle is highly unequal between genders and women are held responsible for the nutritional well-being of families. This role entails putting the feeding of others before their own. Conclusions: in conclusion, the need to consider the distribution of roles in nutritional health interventions is emphasized, avoiding reproducing risky practices for health and quality of life of food gatekeepers, by overexerting them under the justification of effectiveness in the transmission of healthy habits to families.

Introducción: Introducción: se estudiaron los roles en el ciclo alimentario dentro del entorno doméstico, revisitando el concepto de "portera alimentaria". Métodos: la información se obtuvo de 10 etnografías y 24 entrevistas en profundidad a personas responsables de las tareas alimentarias en hogares de ingresos bajos en Santiago, Chile, durante la pandemia. Se realizó un análisis temático desde el marco de entornos alimentarios y género. Resultados: los resultados mostraron que el tiempo destinado al ciclo alimentario es altamente desigual entre los géneros y se responsabiliza a las mujeres del bienestar nutricional de las familias. Este rol conlleva anteponer la alimentación de los/as otros/as a la propia. Conclusión: la discusión subraya la necesidad de considerar la distribución de roles en las intervenciones de salud nutricional, evitando reproducir prácticas riesgosas para la salud y calidad de vida las porteras alimentarias, al sobreexigirlas bajo la justificación de la eficacia en la transmisión de hábitos saludables a las familias.

Alimentación basada en plantas: la nueva tendencia nutricional / Plant-based diets: the new nutritional trend

En la actualidad cada vez más familias optan por seguir una alimentación basada en plantas (ABP). Es fundamental que pediatras y agentes de salud conozcan estos tipos de patrones alimentarios para asesorar adecuadamente a sus pacientes y derivarlos oportunamente a especialistas capacitados con el objetivo de garantizar un adecuado crecimiento y desarrollo principalmente en la edad pediátrica, evitando posibles consecuencias negativas sobre la salud. La mayoría de las sociedades científicas del mundo considera a las dietas vegetarianas apropiadas para todas las etapas de la vida si están correctamente planificadas, suplementadas y con un seguimiento adecuado por especialistas capacitados. Con respecto a las dietas veganas existen controversias por parte de las distintas sociedades con respecto a si son adecuadas o no en pediatría. Recientemente se han revisado las descripciones respecto a las tipificaciones de una ABP y se ha propuesto una definición estándar de estos tipos de dieta. Los riesgos más significativos asociados a la mala planificación de estas dietas son las deficiencias de calcio, vitamina D y vitamina B12, aunque también se debe tener en cuenta el estado del zinc, selenio, yodo y los ácidos grasos Omega 3. Es importante la planificación diaria de un plato nutricionalmente completo y es incuestionable que quienes siguen estos patrones alimentarios reciban suplementos con vitamina B12 adecuados para cada etapa de la vida. Se requieren más estudios en pediatría para evaluar los efectos de las distintas ABP sobre la ingesta de nutrientes, el estado nutricional, el crecimiento, desarrollo y la prevención de enfermedades no transmisibles (AU)

Currently, an increasing number of families are choosing to follow a plant-based diet (PBD). It is essential that pediatricians and healthcare agents know these types of dietary patterns in order to properly advise their patients and refer them to trained specialists to ensure adequate growth and development, especially in the pediatric age, avoiding possible negative health consequences. Most of the world's scientific societies consider vegetarian diets appropriate for all stages of life if they are adequately planned, supplemented and monitored by trained specialists. However, there is controversy among different societies regarding the appropriateness of vegan diets for children. Recently, there has been a review of descriptions concerning the characteristics of a plant-based diet, leading to a proposed standard definition for these types of diets. The most significant risks associated with poorly planned diets are calcium, vitamin D, and vitamin B12 deficiencies, although zinc, selenium, iodine and omega-3 fatty acid status should also be considered. The daily planning of a nutritionally complete meal is important and it is imperative that those who follow these dietary patterns receive vitamin B12 supplementation appropriate for each stage of life. Further studies in children are needed to evaluate the effects of different PBDs on nutrient intake, nutritional status, growth, development, and prevention of noncommunicable diseases (AU)
