Visual behavior and socioeconomic and demographic profile of the premature newborns from Federal University of Pernambuco Maternity (UFPE)
OBJECTIVE: To characterize the behavior of premature newborns in the first year of chronological age. METHODS: This is a cross-sectional descriptive study, bound to a longitudinal study titled: Comparison of visual behavior on the first quarter of year of life of premature nursling born at two maternities of Recife/PE. The sample was composed by 52 premature newborns selected from June, 2007 to June, 2008 from the Maternity of the Federal University of Pernambuco (UFPE). Biological, socioeconomic and demographic data was collected through medical records and interviews with progeny. Newborns were evaluated by the Assessment Guide of Visual Ability in Infants. RESULTS: Most of the newborns were male at a gestational period between 33 weeks and 36 weeks and 6 days, showed a good visual behavior development for the age researched, and most of the families showed good socioeconomical and demographic profile. Besides, it was possible to detect ocular signs in 19% of sample, that were referred to an Ophthalmology Service. CONCLUSION: This study results point out the method like an important key in the early detection and visual screening for premature nursling since the first month of life and it led us to believe that clinical view for occupational therapy intervention must be focused not only on biological risks but also at the influence environment in newborn performance.OBJETIVO: Caracterizar o comportamento visual e perfil socioeconĂŽmico e demogrĂĄfico de recĂ©m-nascidos prematuros no primeiro mĂȘs de idade cronolĂłgica. MĂTODOS: Estudo descritivo de corte transversal, aninhado a um estudo longitudinal intitulado: Comparação do comportamento visual no primeiro trimestre de vida de lactentes nascidos prĂ©-termo em duas maternidades da cidade do Recife/PE. A amostra foi composta por 52 recĂ©m-nascidos prematuros recrutados de junho de 2007 a junho de 2008, na Maternidade do Hospital das ClĂnicas da Universidade Federal de Pernambuco. Foram coletados dados biolĂłgicos, socioeconĂŽmicos e demogrĂĄficos dos recĂ©m-nascidos e famĂlias, por meio de consulta aos prontuĂĄrios e entrevista com as genitoras. Para caracterizar o comportamento visual dos recĂ©m-nascidos utilizou-se o MĂ©todo de Avaliação do Comportamento Visual de Lactentes. RESULTADOS: Observou-se que a maioria dos recĂ©m-nascidos era do sexo masculino, com idade gestacional entre 33 semanas e 36 semanas e 6 dias, apresentaram comportamento visuomotor adequado para a faixa etĂĄria pesquisada e que a maioria das famĂlias apresentava boas condiçÔes socioeconĂŽmicas e demogrĂĄficas. Ainda foi possĂvel detectar em 19% da amostra sinais oculares, os quais foram encaminhados para um Serviço de Oftalmologia. CONCLUSĂES: Os resultados apontam o mĂ©todo como um instrumento importante na triagem visual, possibilitando a detecção oportuna de alteraçÔes visuais em lactentes prematuros desde o 1Âș mĂȘs de vida. O olhar clĂnico da avaliação terapĂȘutica ocupacional de lactentes deve voltar-se para a observação do comportamento considerando nĂŁo apenas os riscos biolĂłgicos, mas tambĂ©m a influĂȘncia que os fatores ambientais e sociais exercem sobre o desempenho funcional da criança.3336Conselho Nacional de Desenvolvimento CientĂfico e TecnolĂłgico (CNPq
Accuracy of 99mTc-Ubiquicidin (29-41) scintigraphy on the differential diagnosis of musculoskeletal infectious diseases and sterile inflammations
The differential diagnosis between infection and a sterile inflammatory process is critical and requires imaging techniques that are sensitive and specific. The objective of this systematic review is to determine the accuracy of the 99mTc-ubiquicidin (29-41) scintigraphy on the differential diagnosis of musculoskeletal infectious diseases and sterile inflammations.

Structural basis for both pro- and anti-inflammatory response induced by mannose-specific legume lectin from Cymbosema roseum
Legume lectins, despite high sequence homology, express diverse biological activities that vary in potency and efficacy. In studies reported here, the mannose-specific lectin from Cymbosema roseum (CRLI), which binds N-glycoproteins, shows both pro-inflammatory effects when administered by local injection and anti-inflammatory effects when by systemic injection. Protein sequencing was obtained by Tandem Mass Spectrometry and the crystal structure was solved by X-ray crystallography using a Synchrotron radiation source. Molecular replacement and refinement were performed using CCP4 and the carbohydrate binding properties were described by affinity assays and computational docking. Biological assays were performed in order to evaluate the lectin edematogenic activity. The crystal structure of CRLI was established to a 1.8 Ă
resolution in order to determine a structural basis for these differing activities. The structure of CRLI is closely homologous to those of other legume lectins at the monomer level and assembles into tetramers as do many of its homologues. The CRLI carbohydrate binding site was predicted by docking with a specific inhibitory trisaccharide. CRLI possesses a hydrophobic pocket for the binding of α-aminobutyric acid and that pocket is occupied in this structure as are the binding sites for calcium and manganese cations characteristic of legume lectins. CRLI route-dependent effects for acute inflammation are related to its carbohydrate binding domain (due to inhibition caused by the presence of α-methyl-mannoside), and are based on comparative analysis with ConA crystal structure. This may be due to carbohydrate binding site design, which differs at Tyr12 and Glu205 position. © 2011 Elsevier Masson SAS. All rights reserved

EstratĂ©gias de aquisição da casa prĂłpria: a trajetĂłria de algumas famĂlias negras paulistanas nas dĂ©cadas de 1920 a 1940
In Brazil, there is a cultural belief that property acquisition is the wisest attitude to ensure a safe and stable economy. For generations, the "dream of property ownership" has been cultivated as a horizon to be achieved. Confirming this tendency, since the 1920s, "casa propria" (home ownership) became a notion mobilized in the black press periodicals, circulating as a desirable aspiration and an orientation to the journals public. Between 1924 and 1937, two of the main newspapers of SĂŁo Paulo black press, O Clarim da Alvorada and A Voz da Raça, carried out a campaign in favor of property ownership, spreading among paulista black families the importance of property acquisition. These campaigns are an important sign for the relevance of buying a property for black families at that time. In this paper, we seek to analyze it as an intergenerational social security strategy, through the presentation of three cases of black families that accomplished this goal between 1920s and 1940s. The black families testimonies reported here indicate precocity, specificities and strategies that represent new challenges for the formulation of property ownership problem, from a racial point of view.No Brasil, hĂĄ uma crença cultural de que a atitude mais sĂĄbia para garantir uma economia domĂ©stica segura e estĂĄvel Ă© a aquisição da casa prĂłpria. Por geraçÔes, o âsonho da casa prĂłpriaâ tem sido cultivado como um horizonte a se atingir. Confirmando essa tendĂȘncia, desde a dĂ©cada de 1920, a âcasa prĂłpriaâ torna-se uma noção mobilizada nos periĂłdicos da imprensa negra, circulando em diversos artigos como uma aspiração desejĂĄvel e uma orientação ao pĂșblico dos jornais. Entre 1924 e 1937, dois dos principais jornais da imprensa negra paulista, O Clarim da Alvorada e A Voz da Raça, realizaram uma campanha em favor da casa prĂłpria, difundindo entre as famĂlias negras paulistanas a ideia da importĂąncia da aquisição imobiliĂĄria. Essas campanhas constituem um indĂcio importante da relevĂąncia da aquisição residencial para as famĂlias negras do perĂodo. Neste trabalho, procuramos analisar essa importĂąncia como estratĂ©gia de seguridade social intergeracional, por meio da apresentação de trĂȘs casos de famĂlias negras que realizaram esse objetivo entre as dĂ©cadas de 1920 e 1940. Os depoimentos das famĂlias negras aqui reportados indicamprecocidade, especificidades e estratĂ©gias que representam novos desafios para a reflexĂŁo sobre a formulação do problema da casa prĂłpria, a partir do ponto de vista racial
Mucopolysaccharidosis I, II, and VI: Brief review and guidelines for treatment
Mucopolysaccharidoses (MPS) are rare genetic diseases caused by the deficiency of one of the lysosomal enzymes involved in the glycosaminoglycan (GAG) breakdown pathway. This metabolic block leads to the accumulation of GAG in various organs and tissues of the affected patients, resulting in a multisystemic clinical picture, sometimes including cognitive impairment. Until the beginning of the XXI century, treatment was mainly supportive. Bone marrow transplantation improved the natural course of the disease in some types of MPS, but the morbidity and mortality restricted its use to selected cases. The identification of the genes involved, the new molecular biology tools and the availability of animal models made it possible to develop specific enzyme replacement therapies (ERT) for these diseases. At present, a great number of Brazilian medical centers from all regions of the country have experience with ERT for MPS I, II, and VI, acquired not only through patient treatment but also in clinical trials. Taking the three types of MPS together, over 200 patients have been treated with ERT in our country. This document summarizes the experience of the professionals involved, along with the data available in the international literature, bringing together and harmonizing the information available on the management of these severe and progressive diseases, thus disclosing new prospects for Brazilian patients affected by these conditions
Pervasive gaps in Amazonian ecological research
Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4
While the increasing availability of global databases on ecological communities has advanced our knowledge
of biodiversity sensitivity to environmental changes,5â7 vast areas of the tropics remain understudied.8â11 In
the American tropics, Amazonia stands out as the worldâs most diverse rainforest and the primary source of
Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13â15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazonâs biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus
crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced
environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian
Amazonia, while identifying the regionâs vulnerability to environmental change. 15%â18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by
2050. This means that unless we take immediate action, we will not be able to establish their current status,

Global disparities in surgeonsâ workloads, academic engagement and rest periods: the on-calL shIft fOr geNEral SurgeonS (LIONESS) study
: The workload of general surgeons is multifaceted, encompassing not only surgical procedures but also a myriad of other responsibilities. From April to May 2023, we conducted a CHERRIES-compliant internet-based survey analyzing clinical practice, academic engagement, and post-on-call rest. The questionnaire featured six sections with 35 questions. Statistical analysis used Chi-square tests, ANOVA, and logistic regression (SPSSŸ v. 28). The survey received a total of 1.046 responses (65.4%). Over 78.0% of responders came from Europe, 65.1% came from a general surgery unit; 92.8% of European and 87.5% of North American respondents were involved in research, compared to 71.7% in Africa. Europe led in publishing research studies (6.6 ± 8.6 yearly). Teaching involvement was high in North America (100%) and Africa (91.7%). Surgeons reported an average of 6.7 ± 4.9 on-call shifts per month, with European and North American surgeons experiencing 6.5 ± 4.9 and 7.8 ± 4.1 on-calls monthly, respectively. African surgeons had the highest on-call frequency (8.7 ± 6.1). Post-on-call, only 35.1% of respondents received a day off. Europeans were most likely (40%) to have a day off, while African surgeons were least likely (6.7%). On the adjusted multivariable analysis HDI (Human Development Index) (aOR 1.993) hospital capacity > 400 beds (aOR 2.423), working in a specialty surgery unit (aOR 2.087), and making the on-call in-house (aOR 5.446), significantly predicted the likelihood of having a day off after an on-call shift. Our study revealed critical insights into the disparities in workload, access to research, and professional opportunities for surgeons across different continents, underscored by the HDI
