Lupus eritematoso sistémico asociado a vasculitis de vasos medianos

El Lupus Eritematoso Sistémico (LES) es una enfermedadautoinmune compleja que puede presentarsecon una amplia variedad de manifestacionesclínicas y serológicas, pudiendo afectarcualquier órgano.Las vasculitis se caracterizan por presencia deinfiltrado celular en la pared vascular de polimorfonuclearesy como consecuencia necrosis de lapared. Los síndromes vasculíticos se puedenagrupar en formas primarias, donde el procesofisiopatológico involucra directamente los vasossanguíneos y formas secundarias en las cualesla inflamación vascular ocurre como complicaciónde una enfermedad subyacente, principalmenteenfermedades autoinmunes, o desencadenadaspor factores exógenos como drogas, infeccioneso neoplasias...</p

Population structure of Araucaria angustifolia in the Iguaçu National Park.

Estrutura populacional de Araucaria angustifolia no Parque Nacional do Iguaçu. O objetivo do presente trabalho foi analisar a estrutura populacional, regeneração e distribuição espacial de Araucaria angustifolia (Bertol.) Kuntz no interior de uma floresta natural e na borda de uma floresta com monocultura agrícola. Todos os indivíduos de araucária a partir de 10 cm de altura foram registrados em 200 parcelas de 10 x 10 m, sendo amostrados 479 indivíduos (416 na borda e 63 no interior). Desses, 33 eram fêmeas, 37 machos, 49 juvenis e 360 regenerantes. A estrutura da população apresentou padrão semelhante ao J-invertido. Os indivíduos regenerantes apresentaram principalmente o padrão agregado de distribuição, já para os juvenis, machos e fêmeas o padrão foi uniforme. A densidade do dossel influenciou a frequência de indivíduos, sendo observadas maiores frequências em maiores densidades, indicando que a regeneração da espécie é mais efetiva em ambientes sombreados. Devido ao grande número de indivíduos amostrados em diferentes classes de tamanho, o Parque Nacional do Iguaçu representa um importante remanescente na conservação de A. angustifolia

The role of late adolescents' emotion regulation in the experience of COVID-19 lockdown: A longitudinal study

The COVID-19 pandemic may be considered a unique mass-trauma experience. This study examined the relations between Italian late adolescents' emotion regulation strategies, their anxiety states, and their experience of the lockdown (in terms of discomfort related to restrictions, capacities to create new functional daily routines, and to find positive changes in one's own life) during the first wave of this pandemic. We analysed how participants' reports of cognitive reappraisal and expressive suppression were associated with anxiety states during the 2020 Italian COVID-19 lockdown (large scale physical distancing and movement restrictions) and one month after the lockdown restrictions had been removed. We also examined how cognitive reappraisal, expressive suppression, and anxiety states were linked to late adolescents' experience of lockdown. The participants were 497 Italian adolescents, aged from 17 to 24 years (Mage = 21.11, SD = 1.83). A longitudinal structural equation modelling showed that emotion regulation strategies and anxiety states were not associated across time. Cognitive reappraisal was positively associated with routine reorganization and positive changes. In contrast, participants' expressive suppression was negatively related to their discomfort related to restrictions, ability to functionally reorganise their daily routine, and ability to find positive changes related to the COVID-19 emergency. Anxiety was positively linked to discomfort related to restrictions. The findings are discussed in light of the current literature related to emotion regulation and anxiety. Limitations and implications for practice are presented

Maternal Parenting Practices and Psychosocial Adjustment of Primary School Children

This study was aimed at evaluating the associations between maternal parenting practices (positive, negative/inconsistent, and punitive), children’s difficulties (such as conduct problems, emotional symptoms, peer problems, and hyperactivity), and prosocial behaviors. Participants were 131 Italian mothers of primary school children; mothers were aged between 26 and 52 years (M = 38.38, SD = 5.46); children (54% girls) were aged between 6 and 10 years (M = 7.15, SD = 0.98). Mothers completed two scales assessing their parenting practices and their children’s psychosocial adjustment. A path analysis was run to test the hypothesized model. The results showed the following: (a) maternal positive parenting was negatively and significantly related to children’s conduct problems and hyperactivity, and positively and significantly to children’s prosocial behavior; (b) maternal negative/inconsistent parenting was positively and significantly related to children’s conduct problems, emotional symptoms, and hyperactivity; (c) maternal punitive parenting was positively and significantly related to children’s conduct problems and emotional symptoms. Moreover, the results showed that, according to the mothers’ perceptions, boys tended to exhibit higher levels of hyperactivity and peer problems and lower levels of prosocial behaviors than girls. Overall, this study highlights the unique role of different maternal parenting practices in the psychosocial adjustment of primary school children

Polineuropatía desmielinizante inflamatoria crónica como forma de presentación de lupus eritematoso sistémico

Se describe el caso de una mujer de 35 años que presenta polineuropatía desmielinizante inflamatoria crónica como compromiso neurológico en su diagnóstico inicial de lupus eritematoso sistémico (LES). Si bien el compromiso neurológico es de una prevalencia variable en lupus, la asociación que se describe no es frecuente y tiene importantes connotaciones en el tratamiento
