TL;DR: No association between body image disturbance and subsequent depression in a cohort of university graduates in Spain is found.
Abstract: Body image disturbance is an increasing problem in Western societies and is associated with a number of mental health outcomes including anorexia, bulimia, body dysmorphia, and depression. The aim of this study was to assess the association between body image disturbance and the incidence of depression. This study included 10,286 participants from a dynamic prospective cohort of Spanish university graduates, who were followed-up for a median period of 4.2 years (Seguimiento Universidad de Navarra – the SUN study). The key characteristic of the study is the permanently open recruitment that started in 1999. The baseline questionnaire included information about body mass index (BMI) and the nine figure schemes that were used to assess body size perception. These variables were grouped according to recommended classifications and the difference between BMI and body size perception was considered as a proxy of body image disturbance. A subject was classified as an incident case of depression if he/she was initially free of depression and reported a physician-made diagnosis of depression and/or the use of antidepressant medication in at least one of the follow-up questionnaires. The association between body image disturbance and the incidence of depression was estimated by calculating the multivariable adjusted Odds Ratio (OR) and its 95% Confidence Interval (95% CI), using logistic regression models. The cumulative incidence of depression during follow-up in the cohort was 4.8%. Men who underestimated their body size had a high percentage of overweight and obesity (50.1% and 12.6%, respectively), whereas women who overestimated their body size had a high percentage of underweight (87.6%). The underestimation exhibited a negative association with the incidence of depression among women (OR: 0.72, 95% CI: 0.54 – 0.95), but this effect disappeared after adjusting for possible confounding variables. The proportion of participants who correctly perceived their body size was high (53.3%) and gross misperception was seldom found, with most cases selecting only one silhouette below (42.7%) or above (2.6%) their actual BMI. We found no association between body image disturbance and subsequent depression in a cohort of university graduates in Spain.

TL;DR: In line with its in vitro anti-ZIKV activity, 7DMA reduced viremia and delayed virus-induced morbidity and mortality in infected mice, which validates this small animal model to assess the in vivo efficacy of novel ZIKV inhibitors.
Abstract: Zika virus (ZIKV) is an emerging flavivirus typically causing a dengue-like febrile illness, but neurological complications, such as microcephaly in newborns, have potentially been linked to this viral infection. We established a panel of in vitro assays to allow the identification of ZIKV inhibitors and demonstrate that the viral polymerase inhibitor 7-deaza-2’-C-methyladenosine (7DMA) efficiently inhibits replication. Infection of AG129 (IFN-α/β and IFN-γ receptor knock-out) mice with ZIKV resulted in acute neutrophilic encephalitis with viral antigens accumulating in neurons of the brain and spinal cord. Additionally, high levels of viral RNA were detected in the spleen, liver and kidney, and levels of IFN-γ and IL-18 were systematically increased in serum of ZIKV-infected mice. Interestingly, the virus was also detected in testicles of infected mice. In line with its in vitro anti-ZIKV activity, 7DMA reduced viremia and delayed virus-induced morbidity and mortality in infected mice, which also validates this small animal model to assess the in vivo efficacy of novel ZIKV inhibitors. Since AG129 mice can generate an antibody response, and have been used in dengue vaccine studies, the model can also be used to assess the efficacy of ZIKV vaccines.

TL;DR: Success using the LSSP-PCR technique in profiling the T. cruzi parasites present in the hearts of 13 patients with chagasic cardiopathy and in the esophagi of four patients is reported, suggesting that the genetic variability of the parasite is one of the determining factors of the clinical form of the disease.
Abstract: We have previously shown that a low-stringency single-specific primer–polymerase chain reaction (LSSP- PCR) is a highly sensitive and reproducible technique for the genetic profiling of Trypanosoma cruzi parasites directly in tissues from infected animals and humans. By applying LSSP-PCR to the study of the variable region of kinetoplast minicircle from T. cruzi, the intraspecific polymorphism of the kinetoplast-deoxyribonucleic acid (kDNA) sequence can be translated into individual kDNA signatures. In the present article, we report on our success using the LSSP-PCR technique in profiling the T. cruzi parasites present in the hearts of 13 patients with chagasic cardiopathy and in the esophagi of four patients (three of them with chagasic megaesophagus). In two patients, one with the cardiodigestive clinical form of Chagas disease and the other with cardiopathy and an esophageal inflammatory process, we could study both heart and esophagus and we detected distinct kDNA signatures in the two organs. This provides evidence of a differential tissue distribution of genetically diverse T. cruzi populations in chronic Chagas disease, suggesting that the genetic variability of the parasite is one of the determining factors of the clinical form of the disease.

TL;DR: In this article, the authors analyse tendencias temporais do consumo domiciliar de itens alimenticios no Brasil, levando em conta a extensao e o proposito do seu processamento industrial.
Abstract: OBJETIVO Estimar tendencias temporais do consumo domiciliar de itens alimenticios no Brasil, levando em conta a extensao e o proposito do seu processamento industrial. METODOS Os dados analisados sao provenientes de Pesquisa de Orcamentos Familiares realizadas no Brasil em 1987-1988, 1995-1996, 2002-2003 e 2008-2009. Foram analisadas amostras probabilisticas dos domicilios das areas metropolitanas em todos os periodos mencionados e, nas duas amostras mais recentes, a abrangencia foi nacional. As unidades de analise foram registros de aquisicoes de agregados de domicilios. Os itens alimenticios foram divididos segundo extensao e proposito de seu processamento industrial em: alimentos in natura ou minimamente processados, ingredientes culinarios processados e produtos alimenticios prontos para consumo, processados ou ultraprocessados. A quantidade adquirida de cada item foi convertida em energia. Estimaram-se a disponibilidade diaria total per capita de calorias e a contribuicao dos grupos de alimentos em cada pesquisa. Calcularam-se estimativas por quintos de renda para as pesquisas nacionais. Variacoes temporais foram testadas por teste de diferenca de medias e modelos de regressao linear. RESULTADOS Houve aumento significativo da participacao de produtos prontos para o consumo (de 23,0% para 27,8% das calorias), gracas ao aumento no consumo de produtos ultraprocessados (de 20,8% para 25,4%) entre 2002-2003 e 2008-2009. Houve reducao significativa na participacao de alimentos e de ingredientes culinarios nesse periodo. O aumento da participacao de produtos ultraprocessados ocorreu em todos os estratos de renda. Observou-se aumento uniforme da participacao calorica de produtos prontos para o consumo em areas metropolitanas, novamente a custa de produtos ultraprocessados e acompanhada por reducoes na participacao de alimentos in natura ou minimamente processados quanto de ingredientes culinarios. CONCLUSOES Produtos ultraprocessados apresentam participacao crescente na dieta brasileira, evidenciada desde a decada de 1980 nas areas metropolitanas e confirmada para todo o Pais na decada de 2000.
