Artigo Científico – Microbiota intestinal de gêmeos, obesidade e fenótipos

Abstract: The role of specific gut microbes in shaping body composition remains unclear. We transplanted fecal microbiota from adult female twin pairs discordant for obesity into germ-free mice fed lowfat mouse chow, as well as diets representing different levels of saturated fat and fruit and vegetable consumption typical of the USA. Increased total body and fat mass, as well as obesityassociated metabolic phenotypes were transmissible with uncultured fecal communities, and with their corres...

Artigo Científico – Anticoncepcionais orais e necessidades nutricionais

Abstract. – Oral contraceptives (OCs) are a major class of prescription drug, used by a large proportion of women starting from early adolescence. Much research has been conducted to investigate the physiological changes that occur in women who take OCs. These include changes in general health as well as in nutritional needs. In terms of nutrition, several studies investigated whether women on OCs need different amounts of some vitamins and minerals. In particular, a report from the World ...

Artigo Científico – Adaptações à dieta sem gluten em pacientes com doença celíaca

Abstract: Celiac disease is emerging in India and has become a public health problem. Almost 6–8 million Indians are estimated to have celiac disease. While there is a large pool of patients with celiac disease in India, until now, only a fraction of them have been diagnosed. With increasing awareness about celiac disease amongst health care providers and the general population, a massive increase in the number of patients with celiac disease is expected now and in the subsequent decade in ...

Artigo Científico – Microbiota Intestinal e diabetes tipo 1 evidencias

Despite years of appreciating the potential role of environment to influence the pathogenesis of type 1 diabetes, specific agents or mechanisms serving in such a capacity remain ill defined. This is exceedingly disappointing as the identification of factors capable of modulating the disease, either as triggers or regulators of the autoimmune response underlying type 1 diabetes, would not only provide clues as to why the disorder develops but, in addition, afford opportunities for improved ...

Artigo Científico – Microbiota de idosos e sindrome metabolica

Obesity has been linked to the human gut microbiota; however, the contribution of gut bacterial species to the obese phenotype remains controversial because of conflicting results from studies in different populations. To explore the possible dysbiosis of gut microbiota in obesity and its metabolic complications, we studied men and women over a range of body mass indices from the Old Order Amish sect, a culturally homogeneous Caucasian population of Central European ancestry. We character...

Artigo Científico – Detox Alternativa

Background: The concept that alternative therapies can eliminate toxins and toxicants from the body, i.e. ‘alternative detox’ (AD) is popular. Sources of data: Selected textbooks and articles on the subject of AD. Areas of agreement: The principles of AD make no sense from a scientific perspective and there is no clinical evidence to support them. Areas of controversy: The promotion of AD treatments provides income for some entrepreneurs but has the potential to cause harm to ...

Artigo Científico – Aditivos quimicos e TDAH

Abstract The effect of artificial food colors (AFCs) on child behavior has been studied for more than 35 years, with accumulating evidence from imperfect studies. This article summarizes the history of this controversial topic and testimony to the 2011 Food and Drug Administration Food Advisory Committee convened to evaluate the current status of evidence regarding attention-deficit/hyperactivity disorder (ADHD). Features of ADHD relevant to understanding the AFC literature are explai...

Artigo Científico – Microbioma, autoimunidade e diabetes tipo 1

Recent studies have suggested a bacterial role in the development of autoimmune disorders including type 1 diabetes (T1D). Over 30 billion nucleotide bases of Illumina shotgun metagenomic data were analyzed from stool samples collected from four pairs of matched T1D case-control subjects collected at the time of the development of T1D associated autoimmunity (i.e., autoantibodies). From these, approximately one million open reading frames were predicted and compared to the SEED protein ...

Artigo Científico – Tipo de parto e composição microbiota

Upon delivery, the neonate is exposed for the first time to a wide array of microbes from a variety of sources, including maternal bacteria. Although prior studies have suggested that delivery mode shapes the microbiota’s establishment and, subsequently, its role in child health, most researchers have focused on specific bacterial taxa or on a single body habitat, the gut. Thus, the initiation stage of human microbiome development remains obscure. The goal of the present study was to ...

Artigo Científico – Enxaqueca, restrição dietetica e IgG

Introduction: It is well-known that specific foods trigger migraine attacks in some patients. We aimed to investigate the effect of diet restriction, based on IgG antibodies against food antigens on the course of migraine attacks in this randomised, double blind, cross-over, headache-diary based trial on 30 patients diagnosed with migraine without aura. Methods: Following a 6-week baseline, IgG antibodies against 266 food antigens were detected by ELISA. Then, the patients were randomised ...
