Health-related quality of life in Spanish women with osteoporosis

OBJETIVO: Analisar a qualidade de vida relacionada à saúde de pacientes com osteoporose e compará-la com a população geral. MÉTODOS: Foi realizado um estudo descritivo transversal com 60 pacientes do sexo feminino no serviço de reumatologia de um hospital universitário na Espanha, de abril a outubro de 2003. Foi aplicado o questionário Short Form-36, abordando dados demográficos, características clínicas e dados sobre estilos de vida relacionados à saúde. As pacientes foram classificadas em grupos etários. Foram utilizados os seguintes testes estatísticos: qui-quadrado, modelo linear geral, t de Student. RESULTADOS: As entrevistadas tinham idade média de 65,57 (DP: ±9,7 anos), e tempo de diagnóstico médio de 3,4±2,84 anos. As melhores pontuações foram obtidas nas dimensões aspectos sociais (89), aspectos emocionais (72,2) e saúde mental (63). As mais baixas foram em estado geral de saúde (45,1), capacidade funcional (47,7), dor (52,3) e aspectos físicos (59,9). As pontuações médias dos pacientes resultaram inferiores às pontuações conhecidas da população geral espanhola nas dimensões capacidade funcional, aspectos físicos, dor e estado geral de saúde. As máximas diferenças entre as pontuações médias do SF-36 dos pacientes e os valores populacionais espanhóis correspondem ao grupo de idade de 55 a 64 anos. Nas demais dimensões do SF-36, as pontuações foram inferiores ou similares aos valores populacionais espanhóis. Não se encontraram associações significativas entre as dimensões do SF-36 estudadas e os dados clínicos, demográficos e de estilos de vida analisados. CONCLUSÕES: Os pacientes apresentaram baixa qualidade de vida, sobretudo nas dimensões mais relevantes da enfermidade, quando comparada com valores da população espanhola em geral. As áreas físicas foram as mais afetadas.OBJECTIVE: To analyze the health-related quality of life in patients with osteoporosis and to compare it with the overall population. METHODS: A cross-sectional descriptive study was carried out with 60 female patients of the rheumatology service at a university hospital, in Spain, from April to October 2003. The Short Form-36 (SF-36) questionnaire was applied in order to obtain demographic data, clinical characteristics and data about lifestyles related to health. Patients were classified in age groups. The statistics tests performed were Chi-square, general linear model, Student\u27s t-test. RESULTS: The interviewees\u27 average age was 65.57 years old (SD: ±9.7 years), and average time interval for diagnosis was 3.4±2.84 years. The best scores were in social functioning (89), emotional aspects (72.2), mental health (63), and vitality (53.7). The lowest scores were in general health (45.1), physical capacity (47.7), pain (52.3) and physical aspects (59.9). The patients\u27 average scores were lower than the general Spanish population\u27s scores in the following dimensions: functional capacity, physical aspects, pain and overall health status. The greatest differences between the average SF-36 scores for patients and for the overall Spanish population were in the age group ranging from 55 to 64 years old. Scores were lower or similar to the general Spanish population in all other dimensions of the questionnaire. No significant associations were found between the dimensions of the SF-36 contemplated in this study and the clinical, demographic and lifestyle data. CONCLUSIONS: The patients presented bad quality of life, particularly with respect to those dimensions that are most relevant with respect to osteoporosis, when compared with the overall Spanish population. The physical dimensions were the ones most affected

Exploring the social cognition network in young adults with autism spectrum disorder using graph analysis

Background: Autism spectrum disorder (ASD) is characterized by an impairment in social cognition (SC). SC is a cognitive construct that refers to the capacity to process information about social situations. It is a complex network that includes distinct components. Exploring how SC components work together leads to a better understanding of how their interactions promote adequate social functioning. Our main goal was to use a novel statistical method, graph theory, to analyze SC relationships in ASD and Typically Developing (TD) individuals. Methods: We applied graph theory to SC measures to verify how the SC components interact and to establish which of them are important within the interacting SC network for TD and ASD groups. Results: The results showed that, in the TD group, the SC nodes are connected; their network showed increased betweenness among nodes, especially for the Theory of Mind. By contrast, in the SC network in the ASD group the nodes are highly disconnected, and the efficient connection among the components is absent. Conclusion: ASD adults do not show SC competencies and functional communication among these skills. Under this regard, specific components are crucial, suggesting they could represent critical domains for ASD SC

Chemical Cues Influence Pupation Behavior of Drosophila simulans and Drosophila buzzatii in Nature and in the Laboratory

In the wild, larvae of several species of Drosophila develop in heterogeneous and rapidly changing environments sharing resources as food and space. In this scenario, sensory systems contribute to detect, localize and recognize congeners and heterospecifics, and provide information about the availability of food and chemical features of environments where animals live. We investigated the behavior of D. simulans and D. buzzatii larvae to chemicals emitted by conspecific and heterospecific larvae. Our goal was to understand the role of these substances in the selection of pupation sites in the two species that cohabit within decaying prickly pear fruits (Opuntia ficus-indica). In these breeding sites, larvae of D. simulans and D. buzzatii detect larvae of the other species changing their pupation site preferences. Larvae of the two species pupated in the part of the fruit containing no or few heterospecifics, and spent a longer time in/on spots marked by conspecifics rather than heterospecifics. In contrast, larvae of the two species reared in isolation from conspecifics pupated randomly over the substrate and spent a similar amount of time on spots marked by conspecifics and by heterospecifics. Our results indicate that early chemically-based experience with conspecific larvae is critical for the selection of the pupation sites in D. simulans and D. buzzatii, and that pupation site preferences of Drosophila larvae depend on species-specific chemical cues. These preferences can be modulate by the presence of larvae of the same or another species

Nacionalismo y americanismo entre los voluntarios chilenos en el Ejército Libertador de Cuba durante su segunda guerra de independencia (1895-1898)

The war of independence of Cuba from 1895-1898 mobilized a large contingent of Chilean volunteers to the island, willing to fight alongside the rebels. From documentaries, periodicals and literature —from Cuban and Chilean sources— this paper analyses the motivations and circumstances that summoned them and how they adapted and legitimized themselves in a war that they adopted as their own, despite being foreigners. While an Americanist culture underlies their departure and behavior, it was the redefinition of a renewed nationalism that emerged within the complex situation in Chile during the period preceding the Antillean conflict, which allowed them, most of the time, to be recognized as legitimate fighters by their superior officers and by the troops they commanded.La guerra de independencia de Cuba de 1895-1898 movilizó hacia la isla a un importante contingente de voluntarios chilenos, dispuestos a combatir junto a los insurrectos. A partir de fuentes documentales, periódicas y bibliográficas — cubanas y chilenas—, en el presente artículo se analizan las motivaciones y circunstancias que los convocaron y cómo debieron adaptarse y legitimarse dentro de una guerra que asumieron como propia, no obstante ser extranjeros. Si bien subyace en su partida y sus conductas una cultura americanista, fue la resignificación del renovado nacionalismo surgido en la compleja situación de Chile en el período que precede al conflicto antillano, lo que les permitió, la mayoría de las veces, ser reconocidos como legítimos combatientes por sus oficiales superiores y la tropa que comandaron

Register-based cumulative prevalence of Autism Spectrum Disorders during childhood and adolescence in Central Italy

Background: Studies have evaluated the prevalence of Autism Spectrum Disorders (ASD), focusing on different ages during childhood and adolescence. How cumulative prevalence increases before adulthood remains unclear. Methods: We used data from the Autism Register of the Regional Reference Centre for Autism in L'Aquila, Central Italy, to retrieve information on individuals born in 2001-2012 with any of the inclusion diagnoses of ASD (DSM criteria) for the period 2001 to 2018. Cumulative prevalence on L'Aquila district population data was calculated as percentages for three-year age strata. Results: All prevalence data were estimated at December 31st, 2018. The overall crude prevalence was 0.95% (352 cases over 36938 population). Cumulative prevalence was 1.19% among those born in 2001-2003 (15 to 17 years of follow up), 1.15% among those born in 2004-2006 (12 to 14 years of follow up), 1.04% among those born in 2007-2009 (9 to 11 years of follow up), 0.80% among those born in 2010-2012 (6 to 8 years of follow up), and 0.57% among those born in 2013-2015 (3 to 5 years of follow up). The proportion of ASD diagnoses until the age of 5 years, compared to the group diagnosed 6 to 8 years of age, showed a significant increasing trend over calendar time (53.6% for those born in 2001-2003, to 77.0% for those born in 2010-2012). Conclusions: Cumulative prevalence by time period provides a better understanding of ASD occurrence than a point prevalence. We did not find any difference in frequency of diagnosis comparing age strata and year of birth, suggesting that frequencies of ASD diagnosis remained roughly constant from 2001 to 2015. Results show that cumulative prevalence of autism diagnosis does not substantially change over time; instead, diagnosis of ASD is more likely at earliest ages over time, although new cases of ASD are also detected at later ages

Finding needles in haystacks: linking scientific names, reference specimens and molecular data for Fungi

DNA phylogenetic comparisons have shown that morphology-based species recognition often underestimates fungal diversity. Therefore, the need for accurate DNA sequence data, tied to both correct taxonomic names and clearly annotated specimen data, has never been greater. Furthermore, the growing number of molecular ecology and microbiome projects using high-throughput sequencing require fast and effective methods for en masse species assignments. In this article, we focus on selecting and re-annotating a set of marker reference sequences that represent each currently accepted order of Fungi. The particular focus is on sequences from the internal transcribed spacer region in the nuclear ribosomal cistron, derived from type specimens and/or ex-type cultures. Re-annotated and verified sequences were deposited in a curated public database at the National Center for Biotechnology Information (NCBI), namely the RefSeq Targeted Loci (RTL) database, and will be visible during routine sequence similarity searches with NR_prefixed accession numbers. A set of standards and protocols is proposed to improve the data quality of new sequences, and we suggest how type and other reference sequences can be used to improve identification of Fungi

Phosphorylation of AIB1 at Mitosis Is Regulated by CDK1/CYCLIN B

Although the AIB1 oncogene has an important role during the early phase of the cell cycle as a coactivator of E2F1, little is known about its function during mitosis.Mitotic cells isolated by nocodazole treatment as well as by shake-off revealed a post-translational modification occurring in AIB1 specifically during mitosis. This modification was sensitive to the treatment with phosphatase, suggesting its modification by phosphorylation. Using specific inhibitors and in vitro kinase assays we demonstrate that AIB1 is phosphorylated on Ser728 and Ser867 by Cdk1/cyclin B at the onset of mitosis and remains phosphorylated until exit from M phase. Differences in the sensitivity to phosphatase inhibitors suggest that PP1 mediates dephosphorylation of AIB1 at the end of mitosis. The phosphorylation of AIB1 during mitosis was not associated with ubiquitylation or degradation, as confirmed by western blotting and flow cytometry analysis. In addition, luciferase reporter assays showed that this phosphorylation did not alter the transcriptional properties of AIB1. Importantly, fluorescence microscopy and sub-cellular fractionation showed that AIB1 phosphorylation correlated with the exclusion from the condensed chromatin, thus preventing access to the promoters of AIB1-dependent genes. Phospho-specific antibodies developed against Ser728 further demonstrated the presence of phosphorylated AIB1 only in mitotic cells where it was localized preferentially in the periphery of the cell.Collectively, our results describe a new mechanism for the regulation of AIB1 during mitosis, whereby phosphorylation of AIB1 by Cdk1 correlates with the subcellular redistribution of AIB1 from a chromatin-associated state in interphase to a more peripheral localization during mitosis. At the exit of mitosis, AIB1 is dephosphorylated, presumably by PP1. This exclusion from chromatin during mitosis may represent a mechanism for governing the transcriptional activity of AIB1
