Iodine deficiency is an important clinical and public health problem. Its prevention begins with an adequate intake of iodine during pregnancy. International agencies recommend at least 200 microg iodine per d for pregnant women. We assessed whether iodine concentrations in the amniotic fluid of healthy pregnant women are independent of iodine intake. This cross-sectional, non-interventional study included 365 consecutive women who underwent amniocentesis to determine the fetal karyotype. The amniocentesis was performed with abdominal antisepsis using chlorhexidine. The iodine concentration was measured in urine and amniotic fluid. The study variables were the intake of iodized salt and multivitamin supplements or the prescription of a KI supplement. The mean level of urinary iodine was 139.0 (SD 94.5) microg/l and of amniotic fluid 15.81 (SD 7.09) microg/l. The women who consumed iodized salt and those who took a KI supplement had significantly higher levels of urinary iodine than those who did not (P = 0.01 and P = 0.004, respectively). The urinary iodine levels were not significantly different in the women who took a multivitamin supplement compared with those who did not take this supplement, independently of iodine concentration or multivitamin supplement. The concentrations of iodine in the amniotic fluid were similar, independent of the dietary iodine intake. Urine and amniotic fluid iodine concentrations were weakly correlated, although the amniotic fluid values were no higher in those women taking a KI supplement. KI prescription at recommended doses increases the iodine levels in the mother without influencing the iodine levels in the amniotic fluid.

CONTEXT Soluble TNF-like weak inducer of apoptosis (sTWEAK) is generated by the intracellular proteolytic cleavage of full-length membrane-bound TNF-like weak inducer of apoptosis (mTWEAK). sTWEAK levels are reduced in diseases with an inflammatory component. Additionally, sTWEAK hampers TNFα activity in human cells. OBJECTIVES The objectives of the study were as follows: 1) to determine circulating sTWEAK in severe obesity and after bariatric surgery; 2) to study m/sTWEAK and its receptor fibroblast growth factor-inducible 14 (Fn14) protein expression in sc adipose tissue (SAT) of severely obese subjects, in SAT stromal vascular fraction (SVF), and isolated adipocytes and in human monocyte-derived macrophages; and 3) to explore, on human adipocytes, the sTWEAK effect on TNFα proinflammatory activity. DESIGN sTWEAK levels were measured in cohort 1: severely obese subjects (n = 23) and a control group (n = 35); and in cohort 2: (n = 23) severely obese subjects before and after surgery. The m/sTWEAK and Fn14 expressions were determined in SAT biopsies, SVF, and isolated adipocytes from severely obese and control subjects and in human monocyte-derived macrophages. In human primary cultured adipocytes, sTWEAK pretreated and TNFα challenged, IL-6, IL-8, and adiponectin protein and gene expressions were determined and nuclear factor-κ B and MAPK signaling analyzed. RESULTS sTWEAK levels were reduced in severely obese subjects. After surgery, sTWEAK levels rose in 69% of patients. mTWEAK protein expression was increased in SAT and SVF of severely obese subjects, whereas Fn14 was up-regulated in isolated adipocytes. M2 human monocyte-derived macrophages overexpress mTWEAK. In human adipocytes, sTWEAK down-regulates TNFα cytokine production by hampering TNFα intracellular signaling events. CONCLUSION The decrease of sTWEAK in severely obese patients may favor the proinflammatory activity elicited by TNFα.

Gastric (GC) and breast (BrC) cancer are two of the most common and deadly tumours. Different lines of evidence suggest a possible causative role of viral infections for both GC and BrC. Wide genome sequencing (WGS) technologies allow searching for viral agents in tissues of patients with cancer. These technologies have already contributed to establish virus-cancer associations as well as to discovery new tumour viruses. The objective of this study was to document possible associations of viral infection with GC and BrC in Mexican patients. In order to gain idea about cost effective conditions of experimental sequencing, we first carried out an in silico simulation of WGS. The next-generation-platform IlluminaGallx was then used to sequence GC and BrC tumour samples. While we did not find viral sequences in tissues from BrC patients, multiple reads matching Epstein-Barr virus (EBV) sequences were found in GC tissues. An end-point polymerase chain reaction confirmed an enrichment of EBV sequences in one of the GC samples sequenced, validating the next-generation sequencing-bioinformatics pipeline.

O estudo analisa a evolução da procura pelo Curso de Graduação em Enfermagem da Universidade Federal de São Carlos (UFSCar), desde o 1º vestibular em 1977 até 1996. Nessa análise serão utilizados comparativamente os dados dos Cursos da Universidade de São Paulo (USP) e da Escola Paulista de Medicina, atualmente denominada Uiversidade Federal de São Paulo (UNIFESP). A crise econômica e do setor da saúde influíram significativamente na queda súbita da procura pelos Cursos na década de 80. Em 1990 o vestibular da UFSCar passou a ser realizado pela Fundação Universitária para o Vestibular (FUVEST). Nesse ano a relação candidato/ vaga atingiu seu nível mais baixo, desde 1977. A partir de 1991, a tendência de retomada do crescimento econômico, e a implantação do Sistema Único de Saúde (SUS) determinaram o crescimento da demanda. Dos três cursos da carreira da Enfermagem na FUVEST, o da UFSCar que é o único do interior do Estado, ainda é o mais procurado em 3ª opção, apesar da procura em 1ª opção ter passado de 2,0 em 1990 para 6,0 em 1995, caindo para 4,6 em 1996. A pouca procura em 1990; os critérios de corte e o procedimento de chamada dos candidatos classificados concorreram para que das 30 vagas oferecidas fossem repreenchidas apenas 15, mesmo com dois vestibulares.

Report for the scientific sojourn carried out at the Institut National d'Histoire de l'Art (INHA), France, from 2010 to 2012. It has focused on the analysis and editing of tales of human apparitions from the other world belonging to the Catalan culture or referring to it. We have studied and edited different versions of the process of Esperança Alegre (Lleida, 1500) and the Peregrinació del Venturós Pelegrí. These medieval works have been preserved in sources of the late sixteenth century or later. We have located a manuscript of the Esperança Alegre's tale, unknown to us at the beginning of this research (Biblioteca Nacional de España, ms. 1701), which differs from the version of ms. Baluze 238 of the Bibliothèque Nationale de France. The scribe of the ms. 1701 adds several paragraphs where considers the case as a diabolical phantasmagoria. About the Venturós Pelegrí, we have tried to establish firm criteria for the classification of many editions from the seventeenth to nineteenth centuries. We have been looking for printed books in the libràries of the world and we have made several requests for photographic reproductions, in order to classify undated editions by comparing woodcuts and other decorative elements. In the legend of Prince Charles of Viana (1421-1461), the appearances of his ghost are accompanied by rumors of his poisoning and of his sanctity. In addition, we have studied the cycles of masses for the souls in Purgatory linked to the hagiographies of St. Amadour and St. Vincent Ferrer, as well as the appearances described in L'Ànima d’Oliver of Francesc Moner, in the Carmelite chronicles of Father John of St. Joseph (1642-1718) and in some folktales collected from the eighteenth to the twentieth century. All this have allowed us to verify the evolution of certain cultural paradigms since the Middle Ages to the present.
