Differential Gene Expression Associated with Soybean Oil Level in the Diet of Pigs

The aim of this study was to identify the differentially expressed genes (DEG) from the skeletal muscle and liver samples of animal models for metabolic diseases in humans. To perform the study, the fatty acid (FA) profile and RNA sequencing (RNA-Seq) data of 35 samples of liver tissue (SOY1.5, n = 17 and SOY3.0, n = 18) and 36 samples of skeletal muscle (SOY1.5, n = 18 and SOY3.0, n = 18) of Large White pigs were analyzed. The FA profile of the tissues was modified by the diet, mainly those related to monounsaturated (MUFA) and polyunsaturated (PUFA) FA. The skeletal muscle transcriptome analysis revealed 45 DEG (FDR 10%), and the functional enrichment analysis identified network maps related to inflammation, immune processes, and pathways associated with oxidative stress, type 2 diabetes, and metabolic dysfunction. For the liver tissue, the transcriptome profile analysis revealed 281 DEG, which participate in network maps related to neurodegenerative diseases. With this nutrigenomics study, we verified that different levels of soybean oil in the pig diet, an animal model for metabolic diseases in humans, affected the transcriptome profile of skeletal muscle and liver tissue. These findings may help to better understand the biological mechanisms that can be modulated by the diet.fals

Aspectos psicossociais em cirurgia bariátrica: a associação entre variáveis emocionais, trabalho, relacionamentos e peso corporal Psychosocial aspects in bariatric surgery: the association among emotional variables, job, relationships and body weight

RACIONAL: Operações bariátricas têm sido consideradas alternativa para o tratamento de obesidade mórbida. Alguns eventos adversos que as pessoas experimentam após o tratamento frequentemente são consequência da falta de conhecimento consistente associada a fatores psicossociais que estão relacionadas ao status pré-operatório dos pacientes. OBJETIVO: Avaliar as variáveis ?psicossociais de 414 candidatos ? cirurgia bari?trica do Hospital de Cl?nicas da Faculdade de Medicina da Universidade de S?o Paulo, Ribeir?o Preto, SP, Brasil. psicossociais de 414 candidatos à cirurgia bariátrica do Hospital de Clínicas da Faculdade de Medicina da Universidade de São Paulo, Ribeirão Preto, SP, Brasil. MÉTODOS: Foram utilizados entrevista semi-estruturada, Inventário de Depressão de Beck (BDI), Inventário de Ansiedade de Beck (BAI) e Binge Eating Scale (BES). RESULTADOS: IMC foi maior entre os pacientes que não tinham emprego (p = 0,019), do sexo feminino, os que tinham um parceiro e os pacientes com IMC <50 kg / m², todos eles desejando ter peso menor (p<0,001). Escores do BAI foram maiores entre os pacientes que não tinham emprego (p <0,05) e maior naqueles com IMC> 50 kg / m² (p <0,05). BDI foram mais altos entre as mulheres (p <0,05) e menores entre aqueles que tinham um emprego (p <0,01). Nenhuma diferença no BES foi encontrada. CONCLUSÕES: Os dados sugerem que as mulheres apresentaram indicadores mais elevados de ansiedade e depressão, sugerindo que elas tinham funcionamento psicológico mais frágil com dificuldades em lidar com a angústia. Auto-percepção, assim como competências e habilidades, podem refletir aspectos internos da personalidade do indivíduo. Pacientes que tiveram um emprego antes da operação parecia ter mais recursos emocionais. Assim, eles podiam sentir menos sofrimento, porque o emprego podia protegê-los. Mulheres e aqueles que não tinham emprego eram mais propensos a apresentar sintomas de depressão. Além disso, pacientes que não tinham emprego e aqueles com IMC> 50 kg / m² foram mais propensos a apresentar sintomas de ansiedade.<br>BACKGROUND: Bariatric surgeries have been considered an alternative for treatment of morbid obesity. Some adverse events that people experience after the treatment frequently are the consequence of the lack of consistent knowledge associated with psychosocial factors that are related to the pre-surgery status of the patients. AIM: To evaluate psychosocial variables of 414 candidates for bariatric surgery from Clinical Hospital of Medical School at University of São Paulo, Ribeirão Preto, SP, Brazil. METHODS: Semi-structured interview, Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI) and Binge Eating Scale (BES) were used. RESULTS: BMI was higher among patients who had no employment (p = 0.019). Female, patients who had a partner and patients with a BMI < 50 kg/m², all of them desired have a lower weight (p < 0.001). BAI scores were higher among patients who had no employment (p < 0.05) and higher among those with a BMI > 50 kg/m² (p < 0.05). BDI scores were higher among women (p < 0.05) and lower among those who had an employment (p < 0.01). No difference in BES was found. CONCLUSIONS: The data suggest that women showed higher indicators of anxiety and depression, suggesting that they had a more fragile psychological functioning with difficulties in coping with distress. Self-perception as well as skills and abilities, may reflect internal aspects of individual's personality. Patients who had an employment before surgery seemed have more emotional resources. So, they may feel less distress because the employment may protect them. Women and those who did not have an employment were more likely to experience depression symptoms. Furthermore, patients who did not have an employment and those with BMI> 50 kg / m² were more likely to experience anxiety symptoms
