Análise nutricional de dietas publicadas em revistas não científicas destinadas ao público feminino

A procura do corpo ideal está fortemente ligada à perda de peso, sendo insistentemente abordada na comunicação social, a imagem corporal, têm conotações mais relacionadas com a moda do que com verdadeiros riscos para a saúde das pessoas. A sociedade atual cultiva a boa aparência física, "o conhecido estar em forma", associada a um ideal estético de magreza e, ao mesmo tempo, apela ao consumo de alimentos de elevada densidade calórica. Na busca do corpo ideal, as dietas de emagrecimento publicadas nas revistas poderão ser uma ajuda na concretização deste objetivo. É fácil encontrar em qualquer quiosque, papelaria ou supermercado estrategicamente colocadas, inúmeras revistas que atribuem à imagem corporal honras de primeira página. Na verdade, estas revistas não científicas divulgam dietas para todos os gostos e situações: dietas específicas para emagrecimento localizado, dietas de preparação para a praia ou para corrigir excessos cometidos em épocas festivas. Embora sabendo-se que estas “auto –dietas” constituem um dos métodos mais utilizados para a perda de peso corporal, não se sabe o número de seguidores que elas têm atualmente. Neste contexto, uma vez que a maior delas não contêm informação nutricional, é importante estar alerta para alguns problemas que podem resultar da ingestão recorrente e sem supervisão deste tipo de dietas. Neste âmbito e dada a pertinência do tema, constituiu objetivo principal do presente trabalho, a análise nutricional de dietas publicadas em revistas não científicas, destinadas ao público feminino em termos de macronutrientes e micronutrientes, sendo também considerado o número de refeições/dia e a variedade de alimentos recomendados. Assim, foram analisadas 15 dietas (497 refeições) publicadas em revistas destinadas ao público feminino, adquiridas entre o ano de 2009 e 2011. A conversão de alimentos em nutrientes foi feita através dos programas informáticos MedPoint e FatSecret. As dietas apresentaram valores energéticos totais (V.E.T.) médios diários, compreendidos entre 378,0 ± 53,8 Kcal e 2335,0 ± 135,0 Kcal. A avaliação dos macronutrientes revelou um teor proteico entre os 32,0 ± 3,6 % e os 12,0 ± 0,1% do total energético Os hidratos de carbono oscilaram entre 63,0 ± 0,1% e 43,0 ± 3,6%. Já a dieta mais rica em lípidos totais apresentava um valor médio de 32,0 ± 9,3% contra os 14,0 ± 0,1% do valor mais baixo encontrado. Nenhuma das dietas assegurava o valor recomendado de ingestão de fibra quando comparada com a dose diária recomendável (DDR). Relativamente à análise dos micronutrientes (vitamina D, vitamina E; vitamina C; vitamina B2, Ácido fólico, cálcio, fósforo, ferro, zinco), somente um tipo de dieta apresentou valores médios diários concordantes com as recomendações preconizadas. Considerando que as dietas analisadas tinham como objetivo a perda rápida de peso, estas revelaram-se maioritariamente hipocalóricas apresentando desequilíbrios e carências de determinados macronutrientes e micronutrientes que poderão, quando mantidas num período de tempo alargado ter consequências graves no desenvolvimento de carência ou outras patologias.

Moléculas coestimulatórias na leishmaniose visceral

Visceral leishmaniasis (VL) is endemic in many countries, including Brazil. The protozoan Leishmania infantum, is the etiological agent of VL, and is transmitted by the bite of female sandflies during the blood meal. The majority of subjects when exposed to the parasite do not develop the disease, because of development of Th1 cellular responses. Those who have develop signs of VL such as fever, weight loss, hepatosplenomegaly, have impairment of the cellular immune response, specific to the Leishmania antigens. We evaluated whether the specififc anergy during symptomatic VL, may be associated with changes in T cells costimulatory molecules or their ligands in CD14+ monocytes. There is an increase in CTLA-4 porcentage on CD4+ T lymphocytes (p=0.001) and ICOS on CD4+ and CD8+ T cells (p=0.002 to CD4+ and p=0.003 to CD8+), after stimulation by soluble Leishmania antigen (SLA) during active visceral leishmaniasis, and that there is a higher percentage of these molecules ex vivo, when comparing symptomatic to recovered individuals (p=0.04 to CTLA-4 in CD4+, and p=0.001 to ICOS in CD4+ and p=0.026 to CD8+). Moreover, we found a high gene expression of CTLA-4, OX-40 and ICOS during active VL. CD40, CD80, CD86, HLA-DR and ICOSL molecules do not suffer changes during disease. There is IFN-γ production by the peripheral blood cells, after SLA stimulation, by peripheral blood cells in symptomatic subjects; however, there is a decrease of the ratio IFN-γ/IL-10, which is reversed after clinical recovery. The impairment of some costimulatory molecules pathways during symptomatic VL could inhibit the ability of phagocytes to kill Leishmania and could facilitate their survival and the proliferation inside macrophages.

Características psicológicas do paciente obeso grave e suas implicações pós-operatórias na cirurgia bariátrica

Obesity is a chronic disease that has multi-factorial aetiology, characterized by high degree of body fat; the degree of obesity will vary according to the Body Mass Index (BMI=m2 /kg). The severe degree of obesity is characterized by BMI>40 and it is regularly associated to endocrine-metabolic or mechanic clinical alterations, and to psychological disorders. Binge Eating (BE) results were overly high for this population. The Bariatric Surgery has been the treatment chosen by those diagnosed with severe obesity as this intervention provides prompt outcomes for loss of weight and clinical improvement conditions. However, recent research has acquiesced that after two years between 20% and 30% of people subject to this intervention gained weight. The main objective of this research is to assess the psychological and behavioral characteristics of those diagnosed with severe obesity that have been subject to Gastric Bypass Surgery in the past 24 months. Specific aspects were investigated: (1) characteristics of different personalities and diagnose of clinic and personality disorders; (2) BE and its relation with loss of weight; (2) the difference between the groups regarding post-surgery care, e.g. physical activity, psychological and dietician input. Method: 40 adults (women and men) aged 23 and 60 year-old who went through a bariatric surgery in the past 24 months, in the city of Natal-RN (Brazil); they were assembled in two groups n=20, Gain group displaying loss of < 50% of their initial surplus of weight, and the Loss group displaying loss of >50%. The research protocol is made of a socio-demographic questionnaire and 3 psychometric instruments: Rorschach – Comprehensive System; Millon Personality Inventory (MCMI-III); and the Binge Eating Scale (Escala de Compulsão Alimentar Periódica (ECAP). Through Rorschach significant differences between these groups were verified according to the kind of personality (EB) - more EB Extratensivo in Gain group and Intratensivo in Loss group – and the lack of control to express affect, increasing the answer for Color Pure at Group I. Concerning the people standardization, the sample as a whole tends to show psychic pain, denigrated selfperception, high levels of self-criticism, distorted perceptions, vulnerability to develop mood disorders and high scores regarding Suicide. MCMI-III results showed more clinic and personality disorders in Group I: Depressive Disorder and Schizotypal, Anxiety, Dysthymia, Major Depressive Disorder; Thought Disorder, Bipolar- Manic and Posttraumatic Stress Disorder. In relation to ECAP, the results indicated significant differences, showing increased BE results in Gain group. There were found significant differences between BE severity and the presence of clinic and personality disorders. Concerning the post-surgery care, the observed differences are statistically significant regarding physical activities with median-increased differences in Loss group. There is a difference between the initial weight and the time post-surgery, indicating that the higher the initial weight and the time after the surgery the higher the re-gain of weight post-surgery. Finally, the results show that the participants with more than 3 years of surgery will have Clinic and Major Depressive Disorders; Somatoform Disorder; Dysthymia. These results confirm prior studies related to BE post-surgery and re-gain of weight as well as the proneness of clinic disorders in severe obesity people. That means the results reinforce that the surgery process is a facet of the severe obesity treatment. The post-surgery process needs to be the main focus of attention and have a long-term input to sustain the care of the surgery results and the quality of life of the patients.

Sinalização endógena do sistema Nociceptina/Orfanina FQ - receptor NOP: envolvimento na modulação da depressão experimental induzida por lipopolissacarídeo

During the last decades, it has been established that there is a relationship between major depression and activation of immune system. Nociceptin/orphanin FQ (N/OFQ) is the natural ligand of a Gi-protein coupled receptor named NOP, both compose the peptidergic system wich is involved in the regulation of mood states and inflammatory responses. Considering these actions, the present thesis aimed to investigate the consequences of blocking NOP signaling in lipopolysaccharide (LPS)-induced sickness and depressive-like behaviors in mice. Systemic administration of LPS doses, that do not cause sepsis in mice, induce changes in their behaviors related with activity of pro-inflammatory cytokines tumor necrosis factor-α (TNF-α) and interleukins 6 (IL-6) and 1β (IL-1 β). At the time points of 2 to 6 h and 24 h after intraperitoneal injection, mice treated with LPS displayed, respectively, sickness and depressive-like behaviors. In the present work the administration of LPS 0.8 mg/kg (ip) significantly induced sickness signs in Swiss and CD-1 mice, such as weight loss, transient reduction in rectal temperature and decrease of food and water intake. Moreover at 24 h after LPS injection these same mice strains displayed significantly increased immobility time on the tail suspension test (TST) when compared with control mice, this alteration was not related with possible locomotion impairments as verified on the open field test. Treatment with Nortriptyline 30 mg/kg (ip, 60 min prior the TST) reduced the immobility time of control and LPS-treated mice and was used as standard antidepressant. The NOP receptor antagonist SB-612111 (10 mg/kg, ip), 30 min prior LPS, did not modify LPS-induced sickness signs and depressive-like behavior. However, when injected 24 h after LPS treatment, SB-612111 (ip, 30 min prior the TST) as well as the peptidergic NOP receptor antagonist UFP-101 (10 nmol/2μL, icv, 5 min prior the TST) significantly reversed the toxin effects. The protocol of LPS-induced depressive-like states was also tested in NOP receptor knockout mice (NOP(-/-)) and their respective wild types (NOP(+/+)). LPS evoked transient rectal temperature reduction in NOP(-/-) mice and loss of body weight, food and water intake reduction in both NOP(+/+) and NOP(-/-) mice. The consumption of water was significantly different due to the genotype. LPS injection induced transient changes in pro-inflammatory cytokines. At 6 h after LPS injection, serum levels of TNF-α were significantly increased in NOP(+/+) and NOP(-/-) mice, as the IL-6 levels were significantly increased just in NOP(+/+) serum. At 24 h after LPS treatment the pro-inflammatory cytokines had returned to the baseline levels in both genotypes. LPS treatment elicited depressive-like effects in NOP(+/+) but not in NOP(-/-) mice. The data obtained during the execution of this doctoral thesis reveal that pharmacological and genetic blockade of NOP signaling does not affect LPS evoked sickness signs while reversing depressive-like behavior. In conclusion, these results highlight the involvement of the peptidergic system N/OFQ - NOP receptor in the modulation of behaviors related to mood and activation of the immune system.

Avaliação da genotoxicidade em mulheres com síndrome dos ovários policísticos: impacto da dieta

Introduction: Polycystic Ovary Syndrome (PCOS), present in 6-12% of women of reproductive age, the criterion of Rotterdam, is characterized by hyperandrogenism, insulin resistance (IR) and its inflammatory state, exacerbated by obesity and factors associated with the increase in damage DNA. Weight loss, combined with healthy eating, acts restoring the reproductive and metabolic functions in the SOP, though its influence in reducing DNA damage in PCOS are unknown. Aim: To investigate whether there are differences between DNA damage markers and factors of cardiometabolic risk in women with PCOS and control, and evaluate the effectiveness of nutritional intervention in DNA damage markers and cardiometabolic risk markers in overweight and obese women with PCOS. Methods: the study was conducted in two studies and the participants were aged between 18 and 35 years. In the first study, a prospective case-control, were included 27 women diagnosed with PCOS and 20 controls. In the second study, clinical trial of nutritional intervention with 12-week calorie-restricted diet 500Kcal / day. The genotoxicity, DNA damage (intensity tail, tail moment and tail length) was evaluated by the comet assay. Anthropometric data, dietary intake, hormonal, biochemical and inflammatory were evaluated in different studies. Results: there was no significant difference between the DNA damage marker tail intensity (p = 0.18), tail moment (p = 0.76) and tail length (p = 0.109) in PCOS when compared to the control group. Data after nutritional intervention in PCOS women with overweight and obesity showed a decrease in DNA damage markers: tail intensity (24.35 ± 5.86 - pre-diet vs. 17.15 ± 5.04 -Post-diet) and tail moment (20.47 ± 7.85 - pre-diet vs. 14.13 ± 6.29 -post-diet) (p <0.001). Reduction of weight (3.5%) and decreased cardiometabolic markers IR and hyperandrogenism. Conclusion: women with PCOS have a worse cardiometabolic risk profile compared to control however similar genotoxicity identified by DNA damage. Nutritional intervention reduced the genotoxicity of overweight and obese women with PCOS, and reduce the factors of cardiometabolic risk.

Efeito anti-inflamatório e antioxidante do extrato hidroalcóolico de Turnera subulata na colite ulcerativa induzida por ácido acético em ratos

Inflammatory bowel diseases is composed by a set of chronic and inflammatory disorders, among them is ulcerative colitis (UC). UC treatment is based on anti-inflammatory administration; however, this group of drugs clearly leads to development of undesirable side effects, what stimulate the search for new therapies alternatives. The aim of this study was to evaluate the effect of hydroalcholic Turnera subulata extract on acetic acid-induced acute UC in rats. UC was induced by 1 mL injection of 4% acetic acid via rectal in Wistar mouse. 42 animals were distributed among 6 experimental groups: Control, UC, Sulfasalazine 500 mg/Kg/day (SSZ), T. subulata 50mg/Kg/day (TS 50), T. subulata 100mg/Kg/day (TS 100), T. subulata 200mg/Kg/day (TS 200). Throughout the experiment, body weight, food and water ingestion was daily evaluated. At the end of the experiment, the animals were euthanized and a colon fragment was observed by macroscopic analysis. Colon fragments were also collected for microscopic analysis and oxidative stress evaluation. The means from each group was compared by ANOVA test with a significance level of 5% (p<0.05) using GraphPad Prism Software. As results, we can clearly observe that SSZ group had the greater body weight decrease among the groups throughout the experiments, 14.78%, as well as, the lowest food intake, 6.23 g of food/day. The animals treated with T. subulata extracts showed no important body weight loss when compared to control. UC group showed the highest tissue damage macroscope score, 6.5, while TS 50 showed the lowest tissue damage score: 1. Microscope evaluation showed the presence of edema, haemorraghia and ulceration in all group of animals, except for Control. Nevertheless, TS 50 showed the lowest inflammatory damage among all groups. Oxidative stress analysis revealed that T. subulata treatment modulate catalase and superoxide dismutase activity, we also observed a decrease in protein and lipid peroxidation in response to extract administration. Taken together, these results shows that T. subulata extract exerts anti-inflammatory and anti-oxidant effects on experimental UC.

Histopathology findings in common marmosets (Callithrix jacchus Linnaeus, 1758) with chronic weight loss associated with bile tract obstruction by infestation with Platynosomum (Loos, 1907)

Chronic weight loss in marmosets is often associated with wasting marmoset syndrome (WMS), an important disease that occurs in callitrichid colonies around the world. Even though its etiology is very difficult to determine, particular variables, such as weight loss, diarrhea and alopecia, associated or not with infestation in the pancreatic ducts with Trichospirura leptossoma (Nematoda: Thelazioidea), seem to be linked with the syndrome. This study investigated the histopathology of the lungs, duodenum, liver, gallbladder, extrahepatic bile ducts and pancreatic ducts of six common marmosets (Callithrix jacchus) suffering from severe non-diarrheic weight loss. Three individuals died naturally and the other three were euthanized. Microscopic findings showed the presence of adult flukes (Platynosomum) in the liver. These flukes, which provoke common infection in cats, were also observed inside the gallbladder as well as in the intra and extrahepatic bile ducts in common marmosets. Portal fibrosis was observed in two animals, which developed chronic fibrosing hepatopathy (biliary pattern, grade 3). The disease progresses without diarrhea and without pancreatic lesions or infestation. With the rogression, the animals presented with ascending cholangitis, cholestasis and portal fibrosis, sometimes culminating in secondary biliary cirrhosis. Therefore, this nfirmity, associated with chronic weight loss in common marmosets, could be another tiological factor linked with WMS

Benefícios nutricionais nos sumos detox: sim ou não?

Introdução e objetivos: Os sumos detox, cuja composição mais elementar se baseia na junção de vegetais e frutas, são uma tendência da actualidade com alegados benefícios para a saúde. São referenciados como uma forma simples de consumir as quantidades diárias recomendadas de legumes e frutas, uma boa forma de eliminar as toxinas do organismo, ou mesmo, uma forma simples de perda de peso. O objetivo deste trabalho foi efetuar o cálculo do valor nutricional de diferentes receitas de sumos detox e a comparação com as doses diárias de referência de macro- e micronutrientes. Materiais e métodos: Com base na informação disponível nas bases de dados de composição de alimentos, efetuou-se o cálculo do valor nutricional de dez receitas de sumos detox. Posteriormente, avaliou-se o contributo nutricional destes sumos usando as doses de referência definidas no Regulamento (UE) N.º 1169/2011. Resultados e discussão: O valor energético das receitas em análise variou entre 79 e 337 kcal. Na sua maioria, os sumos apresentaram um teor relativamente baixo de proteínas e lípidos. No que se refere aos micronutrientes, verificou-se que apesar destes sumos serem maioritariamente compostos por vegetais e frutas, a sua utilização como substituto de refeição pode ser insuficiente para o aporte adequado de alguns micronutrientes. No entanto, 50% dos sumos em análise, se consumidos uma vez por dia, permitem satisfazer as necessidades diárias de vitamina C. Conclusões: Embora o consumo de sumos detox tenha crescido exponencialmente nos últimos anos, as evidências científicas que comprovam os seus benefícios do ponto de vista nutricional são muito limitadas e controversas. De acordo com os resultados obtidos, considera-se que os sumos detox não devem ser utilizados como substitutos exclusivos de um plano alimentar. De futuro pretende-se dar continuidade ao trabalho analisando um maior número de receitas.

Dificuldades no aleitamento materno

Enquadramento: Apesar de o leite materno ser globalmente aceite como o alimento mais completo e efetivo para assegurar a saúde do bebé, além dos claros benefícios para a mãe, continua-se a verificar que a taxa de amamentação está ainda longe da pretendida. Objetivos: Identificar a evidência científica dos determinantes da interrupção do aleitamento materno aos 6 meses de vida do bebé. Métodos: Foi realizada uma revisão sistemática da literatura sobre as dificuldades que levam à interrupção do aleitamento materno aos 6 meses de vida do bebé. Efetuou-se uma pesquisa na PUBMED, The Cochrane Library, Scielo e Google Académic de estudos publicados entre janeiro de 2010 a outubro de 2015, partindo dos critérios de inclusão previamente definidos, os estudos selecionados foram posteriormente avaliados. Dois revisores avaliaram a qualidade dos estudos a incluir, utilizando a grelha para a avaliação crítica de um estudo. Após a avaliação crítica da qualidade, foram incluídos no corpus de estudo 4 artigos com scores entre 87.5% e 95.0%. Resultados: Como metasíntese e seleção da análise dos artigos, inferiu-se que os fatores que levam à interrupção do aleitamento materno aos 6 meses de vida do bebé são: as preocupações com a lactação, perda de peso do bebé, doença da mãe ou a necessidade de tomar medicação, bloqueio dos ductos mamários, problemas relacionados com a gestão psicossocial, conflitos no seu estilo de vida, o posicionamento e pega inadequados, queixa de leite insuficiente ou fraco, dor à amamentação, fissuras, ingurgitamento mamário, a ansiedade materna e o choro da criança. Conclusões: Perante a evidência científica, as causas de abandono do aleitamento materno são multifatoriais e estão associadas à mãe, ao bebé e à saúde. A promoção do aleitamento materno exige programas de educação baseados na evidência, contribuindo para melhoria dos índices nacionais de prevalência da amamentação até, pelo menos aos 6 meses de vida do bebé, que se deseja cada vez mais consentânea com as melhores práticas internacionais. Palavras-Chave: Aleitamento materno; Dificuldades; Interrupção.

Termoterapia e quimioterapia de banana 'Prata-Anã' associadas à temperatura de armazenamento no controle de podridões em pós-colheita

O objetivo deste estudo foi avaliar o efeito da termoterapia (56 ºC por 6 min) e quimioterapia (propiconazole 250 ml.l-1) associado com temperatura de armazenamento (temperatura ambiente, 18 ºC e 13 ºC) no controle de podridões de bananas (Musa spp.) 'Prata-Anã' (AAB) em pós-colheita. Os tratamentos apresentaram diferenças significativas na percentagem de área lesionada por fruto, perda de peso e coloração externa da casca em todas as temperaturas de armazenamento. A quimioterapia e a combinação termoterapia e quimioterapia evitaram a manifestação de podridões nas três condições de armazenamento, enquanto a termoterapia reduziu a percentagem de área lesionada por fruto de 98% para 11% em temperatura ambiente, de 8% para 7% em 18 ºC e de 10% para 0% em 13 ºC, sendo mais eficiente sob a temperatura de 13 ºC. Frutos não tratados perderam 25%, 10% e 3% de peso e atingiram a cor 7, 5 e 1 em temperatura ambiente, 18 ºC e 13 ºC, respectivamente. Frutos tratados com termoterapia e quimioterapia perderam 24, 11 e 5% e 20, 10 e 3%, e atingiram índice médio de cor 4 e 3,5, respectivamente. O período de conservação foi estendido para 18, 24 e 45 dias em temperatura ambiente, 18 ºC e 13 ºC, respectivamente. A combinação dos métodos evitou a manifestação de podridões, reduziu a perda de peso e manteve a cor da casca e a qualidade dos frutos.
