RESUMO

Objective: To adapt the Mind-Wandering Questionnaire (MWQ) for the Brazilian context and present evidence of validity based on its internal structure. Methods: A total of 2,682 Brazilian adults from different regions of the country took part in this study. Confirmatory factor analyses and multigroup confirmatory factor analyses (MGCFA) were performed to assess the factor structure of the MWQ. McDonald's omega (ω) was generated to provide reliability indexes. Results: The analyses demonstrated an adequate factor structure for the MWQ adapted to the Brazilian context, corroborating the original article's single-factor model and other adaptation studies. Furthermore, the results demonstrated the instrument's reliability in a Brazilian population (ω = 0.88). Conclusion: The MWQ is thus an adequate, reliable, and quickly administered instrument for those whose aim is to measure deliberate and spontaneous MW in Brazil.

RESUMO

Background: Phonotimpus pennimani (Araneae, Phrurolithidae) is a small-sized (3-5 mm) spider endemic to the Tacaná volcano in Chiapas, Mexico, where it is found in soil litter of cloud forests and coffee plantations. Its venom composition has so far not been investigated, partly because it is not a species of medical significance. However, it does have an important impact on the arthropod populations of its natural habitat. Methods: Specimens were collected in Southeastern Mexico (Chiapas) and identified taxonomically by morphological characteristics. A partial sequence from the mitochondrial gene coxI was amplified. Sequencing on the Illumina platform of a transcriptome library constructed from 12 adult specimens revealed 25 toxin or toxin-like genes. Transcripts were validated (RT-qPCR) by assessing the differential expression of the toxin-like PpenTox1 transcript and normalising with housekeeping genes. Results: Analysis of the coxI-gene revealed a similarity to other species of the family Phrurolithidae. Transcriptome analysis also revealed similarity with venom components of species from the families Ctenidae, Lycosidae, and Sicariidae. Expression of the toxin-like PpenTox1 gene was different for each developmental stage (juvenile or adult) and also for both sexes (female or male). Additionally, a partial sequence was obtained for the toxin-like PpenTox1 from DNA. Conclusion: Data from the amplification of the mitochondrial coxI gene confirmed that P. pennimani belongs to the family Phrurolithidae. New genes and transcripts coding for venom components were identified.

RESUMO

Introducción: El síndrome de torsión se incluye dentro de los síndromes que causan abdomen agudo quirúrgico. Como causa poco frecuente de este síndrome se encuentra la torsión esplénica en bazos que tienen anomalía en su fijación. Objetivo: Informar sobre la evolución de una paciente tratada por torsión de un bazo errante. Presentación del caso: Paciente de ocho años de edad, femenina, de color no blanco de la piel, con antecedentes de dolor abdominal crónico recurrente, que acudió al Servicio de Urgencias del Hospital Pediátrico de Cienfuegos Paquito González Cueto con dolor abdominal agudo, intermitente, de 48 horas de evolución, vómitos, abdomen doloroso a la palpación profunda en cuadrante superior izquierdo y masa palpable en flanco lateral del mismo lado de tres cm. Se sospechó una torsión esplénica. Se realizó, como complementario diagnóstico ultrasonido abdominal Doppler y tomografía contrastada de abdomen. Se hizo laparotomía y se encontró bazo torcido, con cambios de coloración por la isquemia, que recuperó su color normal después de la destorsión. Se fijó el órgano a la pared abdominal. La evolución posquirúrgica resultó satisfactoria. Conclusiones: La torsión esplénica, aunque infrecuente, debe sospecharse en pacientes con dolor intermitente y masa palpable, principalmente en flanco lateral izquierdo. La tomografía contrastada resulta el examen diagnóstico de elección y se requiere de un diagnóstico temprano para poder conservar el bazo, órgano muy importante para una mejor función inmunológica en los niños(AU)

Introduction: Torsion syndrome is included among the syndromes causing acute surgical abdomen. A rare cause of this syndrome is splenic torsion in spleens with abnormal fixation. Objective: To report on the evolution of a patient treated for torsion of an errant spleen. Case presentation: Eight-year-old female patient, non-white skin color, with a history of recurrent chronic abdominal pain, who attended the Emergency Department of the Paquito González Cueto Pediatric Hospital of Cienfuegos with intermittent acute abdominal pain of 48 hours of evolution, vomiting, painful abdomen on deep palpation in the left upper quadrant and palpable mass in the lateral flank of the same side measuring three centimeters. Splenic torsion was suspected. Doppler abdominal ultrasound and contrasted tomography of the abdomen were performed as a complementary diagnosis. Laparotomy was performed and the spleen was found to be twisted, with changes in color due to ischemia, which recovered its normal color after detorsion. The organ was fixed to the abdominal wall. The postoperative evolution was satisfactory. Conclusions: Splenic torsion, although rare, should be suspected in patients with intermittent pain and palpable mass, mainly in the left lateral flank. Contrast tomography is the diagnostic test of choice and early diagnosis is required to preserve the spleen, a very important organ for better immune function in children(AU)

RESUMO

The goal of this article is to review work on mind wandering, metacognition and creativity in order to consider their relationship with cognitive flexibility. I introduce a model of the role that mind wandering and metacognition have in the generation and exploration of novel ideas and products in the creative process. I argue that managing the interaction between metacognition and mind wandering is the main role of cognitive flexibility in creativity. Furthermore, I claim that balancing the influence of metacognition during the generation and exploration of pre-inventive structures is a quintessential part of creativity, probably in almost any domain. Thus, I advance a general framework that can be applied to understanding how creators monitor and think about their own cognition when they engage in the generation and exploration of ideas. Additionally, I discuss the evolution of controlled and spontaneous cognition and metacognitive judgements during the development of a creative person.

RESUMO

The spleen is supplied by blood flow through the splenic artery and vein. The purpose of this communication is to report an ectopic spleen supplied only by reverse flow through the left gastro-omental vessels. A 14-year-old boy presented with pelvic splenomegaly supplied only by the left gastro-omental artery and veins connected to the inferior polar vessels, which were the only vessels communicating with the spleen. After detorsion of the spleen and splenopexy, the spleen returned to normal dimensions. The patient had uneventful follow-up. In conclusion, the left gastroepiploic vessels are able to maintain the entire spleen blood supply.

O baço é suprido pelo fluxo sanguíneo da artéria e veia esplênicas. O objetivo desta comunicação é apresentar um baço ectópico suprido apenas pelo fluxo sanguíneo reverso proveniente dos vasos gastromentais esquerdos. Um paciente de 14 anos apresentou esplenomegalia pélvica suprida apenas por artéria e veia gastromentais esquerdas, conectadas aos vasos polares inferiores, que eram os únicos presentes nesse baço. Após a distorção do baço e a esplenopexia, o baço voltou às dimensões normais. Não houve intercorrências no acompanhamento do paciente. Em conclusão, os vasos gastromentais esquerdos são capazes de suprir o fluxo sanguíneo de todo o baço.

RESUMO

RATIONALE: Stream of thought describes the nature of the mind when it is freely roaming, a mental state that is continuous and highly dynamic as in mind-wandering or free association. Classic serotonergic psychedelics are known to profoundly impact perception, cognition and language, yet their influence on the stream of thought remains largely unexplored. OBJECTIVE: To elucidate the effects of LSD on the stream of thought. METHODS: In a randomized, double-blind, placebo-controlled, crossover study, 24 healthy participants received 50 µg lysergic acid diethylamide (LSD) or inactive placebo. Mind-wandering was measured by the Amsterdam Resting State Questionnaire (ARSQ), free association by the Forward Flow Task (FFT) for three seed word types (animals, objects, abstract words). ARSQ and FFT were assessed at +0 h, +2 h, +4 h, +6 h, +8 h and +24 h after drug administration, respectively. RESULTS: LSD, compared to placebo, induced different facets of mind-wandering we conceptualized as "chaos" (Discontinuity of Mind, decreased Sleepiness, Planning, Thoughts under Control, Thoughts about Work and Thoughts about Past), "meaning" (Deep Thoughts, Not Sharing Thoughts) and "sensation" (Thoughts about Odours, Thoughts about Sounds). LSD increased the FFT for abstract words reflecting an "abstract flow" under free association. Overall, chaos was strongest pronounced (+2 h to +6 h), followed by meaning (+2 h to +4 h), sensation (+2 h) and abstract flow (+4 h). CONCLUSIONS: LSD affects the stream of thought within several levels (active, passive), facets (chaos, meaning, sensation, abstractness) and time points (from +2 h to +6 h). Increased chaos, meaning and abstract flow at +4 h indicate the utility of a late therapeutic window in psycholytic therapy.

RESUMO

As a result of biodiversity and ecosystem service losses associated with biological invasions, there has been growing interest in basic and applied research on invasive species aiming to improve management strategies. Tradescantia zebrina is a herbaceous species increasingly reported as invasive in the understory of disturbed forest ecosystems. In this study, we assess the effect of spatial and seasonal variation on biological attributes of this species in the Atlantic Forest. To this end, we measured attributes of T. zebrina associated with plant growth and stress in the four seasons at the forest edge and in the forest interior of invaded sites in the Iguaçu National Park, Southern Brazil. The invasive plant had higher growth at the forest edge than in the forest interior and lower leaf asymmetry and herbivory in the winter than in the summer. Our findings suggest that the forest edge environment favours the growth of T. zebrina. This invasive species is highly competitive in the understory of semi-deciduous seasonal forests all over the year. Our study contributes to the management of T. zebrina by showing that the summer is the best season for controlling this species.(AU)

RESUMO

Dirofilaria immitis is a heart and large vessel parasite that mainly affects domestic dogs and has shown a re-emerging zoonosis in recent years. The objective of this study was to determine the prevalence, associated factors, and geographic areas of D. immitis in dogs in the city of Sousa, Paraíba, Northeast Brazil. A total of 320 dogs were selected and evaluated, 160 domiciled and 160 wandering, from the 32 districts of the city. Clinical examination, blood collection, and epidemiological data retrieval were performed for each animal. The sanitation conditions of the environment were visually observed at the time of evaluation. Three methods were used to investigate the morphometric diagnosis of microfilariae: capillary blood smear (ESC), peripheral blood smear (ESP), and modified Knott test. The data were subjected to univariate and multivariate statistics for the observation of risk factors and qualitative assessment of the examinations. Of the 17.5% (56/320) of animals testing positive for D. immitis, 25% (40/160) were wandering and 10% (16/160) were domiciled dogs. Positive dogs were found in 24 of the 32 neighborhoods evaluated, with Angelim and Doutor Zezé having the highest percentages of 1.56% (5/320) each. Only the categories of cardiac alterations (OR 6.231 [1,539-25,236]) and stray dogs (OR 2.463 [1,281-4,735]) demonstrated potential risk factors for infection. Of the 56 positive animals, 28 were positive in the three tests, and another 28 showed variance between methods and/or between prepared slides. No other filaridae were observed. The city of Sousa is considered to have a significant prevalence of infection by D. immitis, and forms of control and prophylaxis are required to reduce the risks of transmission to animals, as well as to humans.

Dirofilaria immitis é um parasito de coração e de grandes vasos que acomete principalmente cães domésticos, também causador de uma zoonose reemergente nos últimos anos. O objetivo deste trabalho foi determinar a prevalência, fatores associados e áreas geográficas de D. immitis em cães na cidade de Sousa, Paraíba, Nordeste do Brasil. Para isso, foram selecionados e avaliados 320 cães, sendo 160 domiciliados e 160 errantes, provenientes dos 32 bairros da cidade. Foi realizado o exame clínico, coleta de sangue e dados epidemiológicos de cada animal. O ambiente foi observado visualmente quanto as condições de saneamento no momento de avaliação. Para pesquisa de microfilárias, foram realizados três métodos: esfregaço sanguíneo capilar (ESC), periférico (ESP) e teste de Knott-modificado, associado ao diagnóstico morfométrico das microfilárias. Os dados foram submetidos a estatísticas uni e multivariadas para observação de fatores de risco e avaliação qualitativa dos exames. Obteve-se prevalência de 17,5% (56/320) de animais positivos para D. immitis, sendo 25% (40/160) errantes e 10% (16/160) domiciliados. Dos 32 bairros avaliados, em 24 foram encontrados cães positivos, sendo Angelim e Doutor Zezé, os bairros com maior percentual 1,56% (5/320) cada. Somente as categorias de alterações cardíacas (OR 6,231 [1.539-25.236]) e cães errantes (OR 2,463 [1.281-4.735]) demonstraram potencial fator de risco para infecção. Dos 56 animais positivos, 28 apresentaram positividade nos três testes, e outros 28 demonstraram variância entre métodos e/ou entre lâminas confeccionadas. Não foram observados outros filarídeos. Considerou-se que a cidade de Sousa apresenta prevalência significativa de infecção por D. immitis, sendo necessário estabelecer formas de controle e profilaxia, para reduzir os riscos da transmissão para animais, como também para humanos.

RESUMO

Mind-wandering seems to be paradigmatically unintentional. However, experimental findings have yielded the paradoxical result that mind-wandering can also be intentional. In this paper, we first present the paradox of intentional mind-wandering and then explain intentional mind-wandering as the intentional omission to control one's own thoughts. Finally, we present the surrealist method for artistic production to illustrate how intentional omission of control over thoughts can be deployed towards creative endeavors.

RESUMO

Este artigo tem por objetivo explorar as intervenções urbanas na cidade de Porto Alegre e seus efeitos sobre os modos de vida na cidade. Tais intervenções podem estar em sintonia com a arte urbana, o a(r)tivismo, o efêmero, o urbanístico, a arquitetura e os movimentos de ocupação dos espaços públicos. A metodologia é traçada através da cartografia e da errância, fazendo do corpo do pesquisador superfície aos acontecimentos. Constrói-se, assim, uma narrativa acerca das forças que compõem a cidade a partir dos efeitos de tais intervenções no tecido urbano. Frente aos imperativos homogeneízadores das cidades - atrelados às premissas do biopoder e da produção capitalística, captam-se efeitos de pausa em uma rotina acelerada, que possibilitam encontros e dissipam o medo urbano. As intervenções urbanas promovem a abertura de limiares que se fazem possibilidade de criação e defesa da potência de vida, entrelaçando-se à produção do novo nas subjetividades emergentes.(AU)

This article aims to explore urban interventions in the city of Porto Alegre and its effects on the ways of life in the city. Such interventions may be in tune with urban art, activism ar, ephemeral, urbanistic, architectural and occupational movements of public spaces. The methodology is traced through cartography and wandering, making the researcher's body surface to events. Thus, a narrative about the forces that compose the city is constructed from the effects of such interventions in the urban environment. In the face of the homogenizing imperatives of cities - linked to the premises of biopower and capitalist production, pause effects are found in an accelerated routine that allow encounters and dissipates urban fear. Urban interventions promote the opening of thresholds that make it possible to create and defend the potency of life, intertwining with the production of the new in emerging subjectivities.(AU)

RESUMO

Wandering spleen is a rare condition, generally due to congenital abnormalities of the dorsal mesogastrium or splenic suspensory ligaments and not traumatic events. The most frequent complication is torsion of the splenic hilus with ischemia or splenic infarction and its association with pancreatic volvulus is extremely rare. There are no reported cases of wandering spleen with pancreatic volvulus in association with a post traumatic Grynfelt-Lesshaft haernia. We present a case of a 43-year-old female patient with an association of these three entities and a history of abdominal trauma.

El bazo errante es una afección rara que en general se debe a anomalías congénitas del mesogastrio dorsal o de los ligamentos suspensores esplénicos, y no a traumatismos. La complicación más frecuente es la torsión del hilio esplénico con isquemia o infarto esplénico, y su asociación a vólvulo pancreático es extremadamente rara. No existen ningún otro caso reportado de bazo errante con vólvulo pancreático en un paciente que presenta una hernia lumbar de Grynfelt-Lesshaft postraumática. Presentamos el caso de una paciente de 43 años con asociación de estas tres afecciones y antecedente de traumatismo abdominal.

RESUMO

Canine leishmaniasis (CanL) is a zoonosis caused by protozoa of the genus Leishmania and remains an important public health concern in tropical areas. In Brazil, domestic dogs are considered the most relevant reservoir of the parasite and one of the main targets of the disease control actions. Considering this, we aimed herein to evaluate the CanL infection in different canine groups and distribution of cases in the state of Sergipe, an endemic region in Northeastern Brazil. The evaluated 467 animals were classified into four groups: hunting (n = 50), company (n = 64), guard (n = 140), and wandering (n = 213). Samples (blood, bone marrow, conjunctival swab, and lymph node aspirate) were collected from animals in nine municipalities of Sergipe. First, all animals were submitted to general and ophthalmic clinical examination. Next, they were tested serologically by TR-DPP®, and for the presence of Leishmania, amastigotes in samples of bone marrow, conjunctival swab, and lymph node aspirate were diagnosed by PCR and parasitological techniques. It was observed that 34.69% (162) of the evaluated dogs were seropositive. The highest rates of positivity were found in hunting 54% (27/50; OR = 3.52; p-value = 0.001) and guard dogs 42.14% (59/140; OR = 2.18; p-value = 0.01). Otherwise, the highest percentage of symptomatic dogs was observed in wandering animals (85%; OR = 9.63; p-value < 0.0001). The distribution of case analysis showed that the highest positivity rates occurred in inland municipalities situated in arid regions. Taken together, our data demonstrate that hunting and guard dogs are among the animals most exposed and affected by clinical manifestations of CanL, mainly in the inland municipalities of Sergipe State.

RESUMO

Resumen El bazo errante es una entidad clínica muy poco frecuente en niños, representando menos del 0.25% de todas las esplenectomías. Puede ocurrir por la ausencia congénita de ligamentos suspensorios del bazo, o debido a una laxitud adquirida de los mismos. El espectro clínico va desde condición asintomática con hallazgo incidental, hasta presentación de abdomen agudo. El conocimiento de esta condición y de sus hallazgos radiológicos, juegan un papel esencial para lograr un diagnóstico correcto y tratamiento quirúrgico oportuno. La preservación del bazo más esplenopexia es el procedimiento de elección. Se presenta un paciente de 4 años con antecedente de cirugía antirreflujo, en quien se encontró bazo ectópico errante con torsión esplénica, que fue manejado exitosamente con conservación del bazo y esplenopexia. MÉD.UIS.2021;34(1): 113-18

Abstract Wandering spleen is an uncommon clinical entity in children, representing less than 0,25% of all splenectomies. It is caused by laxity or absence of the supporting splenic ligaments. Its clinical spectrum varies from asymptomatic disease with incidental finding to acute abdominal pain due to torsion. The knowledge of this condition and its radiological findings plays a crucial role in reaching the correct diagnosis and timely surgical treatment. Spleen preservation with splenopexy is recognized as the procedure of choice. We report a case of a four year old patient with a history of anti-reflux surgery, with a wandering spleen and splenic torsion, successfully managed with spleen conservation and splenopexy.
