Influence of social media on eating habits
A investigação sobre as implicações do uso das redes sociais, nos hábitos alimentares é uma área de investigação pertinente. As redes sociais, criadas para promover a discussão e comunicação entre os seus utilizadores, são palcos de discussão e de influência, onde as questões relacionadas com a alimentação não são exceção. Objetivos: Avaliar a influência das redes sociais nos hábitos alimentares. Metodologia: Realizou-se um estudo quantitativo, transversal, analítico, numa amostra não probabilística do tipo bola de neve (snowball sampling), constituída por 201 indivíduos adultos. Para o efeito recolheram-se dados através de um inquérito online, sendo analisados com recurso ao software IBM SPSS statistics, versão 28. Resultados: A maioria dos inquiridos é utilizador de redes sociais há mais de 10 anos (52,7%), com uma utilização diária entre 1 a 4 horas (71,1%). Quanto aos conteúdos mais procurados nas redes sociais, 47,3% refere a procura de “receitas culinárias” e 45,3% informações sobre “alimentação saudável”. 77,1% dos indivíduos seguem conselhos relativos à alimentação dados por quem seguem nas redes sociais, tendo-se verificado associação com a utilização do Instagram (p-value=0,0379). A maioria refere ter experimentado alimentos novos e/ou receitas, partilhadas nas redes sociais (67,1%), 17,4% começou a fazer jejum intermitente, 16,2% reduziu a ingestão de carne e 14,2% excluiu os Hidratos de Carbono da alimentação. A maioria (63,7%), afirma que é influenciado a comprar alimentos pelas campanhas publicitárias de produtos alimentares difundidas nas redes sociais, tendo-se verificado associação com a utilização do Instagram (p-value=0,023), Facebook (p-value=0,005) e do Messenger (p-value=0,044). Conclusões: Constatou-se que existe influência da utilização das redes sociais nos hábitos alimentares, considerando-se pertinente futuras pesquisas sobre o tema.info:eu-repo/semantics/publishedVersio
Proteome-wide analysis of Trypanosoma cruzi exponential and stationary growth phases reveals a subcellular compartment-specific regulation
Trypanosoma cruzi, the etiologic agent of Chagas disease, cycles through different life stages characterized by defined molecular traits associated with the proliferative or differentiation state. In particular, T. cruzi epimastigotes are the replicative forms that colonize the intestine of the Triatomine insect vector before entering the stationary phase that is crucial for differentiation into metacyclic trypomastigotes, which are the infective forms of mammalian hosts. The transition from proliferative exponential phase to quiescent stationary phase represents an important step that recapitulates the early molecular events of metacyclogenesis, opening new possibilities for understanding this process. In this study, we report a quantitative shotgun proteomic analysis of the T. cruzi epimastigote in the exponential and stationary growth phases. More than 3000 proteins were detected and quantified, highlighting the regulation of proteins involved in different subcellular compartments. Ribosomal proteins were upregulated in the exponential phase, supporting the higher replication rate of this growth phase. Autophagy-related proteins were upregulated in the stationary growth phase, indicating the onset of the metacyclogenesis process. Moreover, this study reports the regulation of N-terminally acetylated proteins during growth phase transitioning, adding a new layer of regulation to this process. Taken together, this study reports a proteome-wide rewiring during T. cruzi transit from the replicative exponential phase to the stationary growth phase, which is the preparatory phase for differentiation
Co-occurrence of colistin-resistance genes mcr-1 and mcr-3 among multidrug-resistant Escherichia coli isolated from cattle, Spain, September 2015
Los genes de resistencia a colistina mcr-3 y mcr-1 se detectaron en un aislado de Escherichia coli de heces de ganado en un matadero español en 2015. Las secuencias de ambos genes se hibridaron a la misma banda de plásmidos de aproximadamente 250 kb, aunque la resistencia a la colistina no fue movilizable . El aislado producía betalactamasas de espectro extendido y pertenecía al serotipo O9: H10 y al tipo de secuencia ST533. Aquí informamos un gen mcr-3 detectado en Europa después de informes anteriores de Asia y los Estados Unidos.Colistin resistance genes mcr-3 and mcr-1 have been detected in an Escherichia coli isolate from cattle faeces in a Spanish slaughterhouse in 2015. The sequences of both genes hybridised to same plasmid band of ca 250 kb, although colistin resistance was non-mobilisable. The isolate was producing extended-spectrum beta-lactamases and belonged to serotype O9:H10 and sequence type ST533. Here we report an mcr-3 gene detected in Europe following earlier reports from Asia and the United States.• Ministerio de Economía, Industria y Competitividad. Proyecto AGL2016-

Detection of Trypanosoma vivax in tissues of experimentally infected goats: what is the role of adipose tissue in the life cycle of this protozoon?
Pathogenesis of reproductive failure induced by Trypanosoma vivax in experimentally infected pregnant ewes
The present study was aimed at investigating the effect of experimental infection by Trypanosoma vivax in different\ud
stages of pregnancy, determining the pathogenesis of reproductive failure, and confirming transplacental\ud
transmission. We used 12 pregnant ewes distributed into four experimental groups: G1, was formed by three ewes\ud
infected with T. vivax in the first third of pregnancy (30 days); G2 comprised three infected ewes in the final third of\ud
pregnancy (100 days); G3 and G4 were composed of three non-infected ewes with the same gestational period,\ud
respectively. Each ewe of G1 and G2 was inoculated with 1.25 × 105 tripomastigotes. Clinical examination,\ud
determination of parasitemia, serum biochemistry (albumin, total protein, glucose, cholesterol, and urea), packed\ud
cell volume (PCV), serum progesterone, and pathological examination were performed. Placenta, amniotic fluid,\ud
blood and tissues from the fetuses and stillbirths were submitted to PCR. Two ewes of G1 (Ewe 1 and 3) presented\ud
severe infection and died in the 34th and 35th days post-infection (dpi), respectively; but both fetuses were\ud
recovered during necropsy. In G2, Ewe 5 aborted two fetuses on the 130th day (30 dpi) of pregnancy; and Ewe 6\ud
aborted one fetus in the 140th day (40 dpi) of gestation. Ewes 2 and 4 delivered two weak lambs that died five\ud
days after birth. Factors possibly involved with the reproductive failure included high parasitemia, fever, low PCV,\ud
body score, serum glucose, total protein, cholesterol, and progesterone. Hepatitis, pericarditis, and encephalitis were\ud
observed in the aborted fetuses. The presence of T. vivax DNA in the placenta, amniotic fluid, blood, and tissues\ud
from the fetuses confirms the transplacental transmission of the parasite. Histological lesion in the fetuses and\ud
placenta also suggest the involvement of the parasite in the etiopathogenesis of reproductive failure in ewes

A many-analysts approach to the relation between religiosity and well-being
The relation between religiosity and well-being is one of the most researched topics in the psychology of religion, yet the directionality and robustness of the effect remains debated. Here, we adopted a many-analysts approach to assess the robustness of this relation based on a new cross-cultural dataset (N=10,535 participants from 24 countries). We recruited 120 analysis teams to investigate (1) whether religious people self-report higher well-being, and (2) whether the relation between religiosity and self-reported well-being depends on perceived cultural norms of religion (i.e., whether it is considered normal and desirable to be religious in a given country). In a two-stage procedure, the teams first created an analysis plan and then executed their planned analysis on the data. For the first research question, all but 3 teams reported positive effect sizes with credible/confidence intervals excluding zero (median reported β=0.120). For the second research question, this was the case for 65% of the teams (median reported β=0.039). While most teams applied (multilevel) linear regression models, there was considerable variability in the choice of items used to construct the independent variables, the dependent variable, and the included covariates

Preneoplastic somatic mutations including MYD88(L265P) in lymphoplasmacytic lymphoma
Normal cell counterparts of solid and myeloid tumors accumulate mutations years before disease onset; whether this occurs in B lymphocytes before lymphoma remains uncertain. We sequenced multiple stages of the B lineage in elderly individuals and patients with lymphoplasmacytic lymphoma, a singular disease for studying lymphomagenesis because of the high prevalence of mutated MYD88. We observed similar accumulation of random mutations in B lineages from both cohorts and unexpectedly found MYD88(L265P) in normal precursor and mature B lymphocytes from patients with lymphoma. We uncovered genetic and transcriptional pathways driving malignant transformation and leveraged these to model lymphoplasmacytic lymphoma in mice, based on mutated MYD88 in B cell precursors and BCL2 overexpression. Thus, MYD88(L265P) is a preneoplastic event, which challenges the current understanding of lymphomagenesis and may have implications for early detection of B cell lymphomas
