INCIDÊNCIA DE TROMBOSE VENOSA PROFUNDA EM JOELHO FLUTUANTE

Objective: To report the incidence between Deep Vein Thrombosis (DVT) in ipsilateral femur and tibia fractures (floating knee), considering its relation with hospitalization time, fracture classification, treatment implemented and comorbidities. Methods: This is a retrospective observational analytical study using the medical charts of thirty patients admitted with floating knee to a trauma hospital between October 2016 and July 2017. Results: Of the 30 patients assessed, 25 (83%) were men and 5 (17%) women. The most affected age range was between 21 and 30 years (36%). The dominant limb was affected in 17 (57%) patients. A total of 19 (63%) patients were classified as Fraser type I, 18 (60%) had open (compound) fractures, 16 (53%) fractures of the tibia and 8 (26%) of the femur. The most widely used emergency treatment was external fixation of the femur and tibia (25 patients = 83%). Seven patients used a femur plate and external fixator in the tibia as definitive treatment. Of the 30 patients studied, 14 (46%) suffered infectious complications, 9 (30%) superficial and 5 (16%) deep. Deep venous thrombosis was observed in 17% of patients (p=0.409).  Conclusion: Despite the use of antithrombotic prophylaxis, there was a high incidence of DVT in the affected limb of patients with floating knee. Fraser I fractures, being male and the non-dominant limb increases the likelihood of developing DVT. Level of Evidence: Level IObjetivo: Relatar a incidência de trombose venosa profunda (TVP) em fratura ipsilateral de fêmur e tíbia (joelho flutuante), levando-se em conta sua relação com o tempo de internação, com a classificação da fratura, o tempo para fazer o procedimento cirúrgico, o tratamento implementado e com as comorbidades. Materiais e métodos: Realizado um estudo retrospectivo, observacional e analítico por meio da avaliação de prontuários de trinta pacientes admitidos com joelho flutuante em um hospital de trauma durante o período de outubro de 2016 a julho de 2017.  Resultados: Dos 30 pacientes avaliados, foi observado que 25 (83%) dos pacientes eram do gênero masculino e 5 (17%) dos pacientes eram do gênero feminino. A faixa etária mais acometida foi entre 21 e 30 anos (36%). O acometimento do membro dominante ocorreu em 17 (57%) dos pacientes avaliados. Dezenove (63%) pacientes acometidos foram classificados como Fraser Tipo I. Dezoito (60%) pacientes tiveram fratura exposta, sendo 16 (53%) em tíbia e 8 (26%) em fêmur. O tratamento mais utilizado como urgência foi o de controle de danos com fixador externo em fêmur e tíbia (25 pacientes ou 83%). Sete pacientes utilizaram placa no fêmur e fixador externo na tíbia como tratamento definitivo. Dos 30 pacientes estudados, 14 (46%) tiveram complicações infecciosas, sendo 9 (30%) superficiais e 5 (16%) profundas. Observamos trombose venosa profunda em 17% dos pacientes (p=0,409).  Conclusão: Apesar do uso da profilaxia antitrombótica medicamentosa, houve uma grande incidência de TVP no membro acometido em pacientes com joelho flutuante na população estudada. As fraturas classificadas como Fraser I, pacientes do sexo masculino e o membro não dominante levaram ao aumento da probabilidade do surgimento de TVP. Nível de Evidência: Nível

Effect of surgical experience and spine subspecialty on the reliability of the {AO} Spine Upper Cervical Injury Classification System

OBJECTIVE The objective of this paper was to determine the interobserver reliability and intraobserver reproducibility of the AO Spine Upper Cervical Injury Classification System based on surgeon experience (< 5 years, 5–10 years, 10–20 years, and > 20 years) and surgical subspecialty (orthopedic spine surgery, neurosurgery, and "other" surgery). METHODS A total of 11,601 assessments of upper cervical spine injuries were evaluated based on the AO Spine Upper Cervical Injury Classification System. Reliability and reproducibility scores were obtained twice, with a 3-week time interval. Descriptive statistics were utilized to examine the percentage of accurately classified injuries, and Pearson’s chi-square or Fisher’s exact test was used to screen for potentially relevant differences between study participants. Kappa coefficients (κ) determined the interobserver reliability and intraobserver reproducibility. RESULTS The intraobserver reproducibility was substantial for surgeon experience level (< 5 years: 0.74 vs 5–10 years: 0.69 vs 10–20 years: 0.69 vs > 20 years: 0.70) and surgical subspecialty (orthopedic spine: 0.71 vs neurosurgery: 0.69 vs other: 0.68). Furthermore, the interobserver reliability was substantial for all surgical experience groups on assessment 1 (< 5 years: 0.67 vs 5–10 years: 0.62 vs 10–20 years: 0.61 vs > 20 years: 0.62), and only surgeons with > 20 years of experience did not have substantial reliability on assessment 2 (< 5 years: 0.62 vs 5–10 years: 0.61 vs 10–20 years: 0.61 vs > 20 years: 0.59). Orthopedic spine surgeons and neurosurgeons had substantial intraobserver reproducibility on both assessment 1 (0.64 vs 0.63) and assessment 2 (0.62 vs 0.63), while other surgeons had moderate reliability on assessment 1 (0.43) and fair reliability on assessment 2 (0.36). CONCLUSIONS The international reliability and reproducibility scores for the AO Spine Upper Cervical Injury Classification System demonstrated substantial intraobserver reproducibility and interobserver reliability regardless of surgical experience and spine subspecialty. These results support the global application of this classification system

Programa de educação pelo trabalho para a saúde nas escolas: oficina sobre sexualidade

Este artigo relata uma experiência de educação em saúde sobre sexualidade, conduzida por monitores do PET-Saúde, da Universidade de Brasília, do subgrupo de Planejamento Familiar. As oficinas foram realizadas com adolescentes de escolas públicas de ensino fundamental e médio dos municípios de Ceres e Santa Isabel, em Goiás. Foram abordadas questões sobre sexualidade; gravidez; métodos anticoncepcionais; doenças sexualmente transmissíveis. Os alunos, divididos em grupos, formularam as perguntas anonimamente e as responderam, por sorteio. Os monitores coordenaram as atividades, orientaram os alunos na elaboração das respostas e simularam o uso de métodos contraceptivos (preservativos masculino e feminino). A experiência evidenciou a importância do desenvolvimento de uma ação crítica, reflexiva e participativa para a promoção da saúde dos adolescentes, abordando-se o tema sexualidade dentro da realidade local. A intenção do trabalho foi estabelecer um meio eficaz e criativo de abordagem dessa temática no âmbito escolar em conjunto com o serviço de atenção básica desses municípios, favorecendo a integração ensino-serviço-comunidade, que é um dos objetivos principais do programa PET-Saúde

Probing the competition between acetate and 2,2′-bipyridine ligands to bind to d-block group 12 metals

Herein, we were interested in probing the competition between 2,2′-bipyridine (2,2′-bipy) and acetate ligands in binding to Zn2+, Cd2+ and Hg2+. We have obtained eight new supramolecular architectures through tuning the proportion of these two ligands. On doubling the acetate availability compared to 2,2′-bipy, complexes with either Zn2+, Cd2+ or Hg2+ were formed with one 2,2′-bipy and two acetate ligands coordinated to the metal center. One water molecule is also coordinated to Zn2+ and Cd2+ in these two complexes, which are reported here for the first time. One 2,2′-bipy is still coordinated to the three metal ions with an acetate excess of 10-times, but another trinuclear Zn2+ complex is formed with two 2,2′-bipy and six acetate ligands (1 : 3 2,2′-bipy : acetate stoichiometry). Upon setting an equimolar ratio of the ligands, the complex [Zn(CH3CO2)(2,2′-bipy)2]+ is formed, while two 2,2′-bipy and two acetate ligands are coordinated to Cd2+, giving rise to a [Cd(CH3CO2)2(2,2′bipy)2] complex. On doubling the 2,2′-bipy availability compared to acetate, the former does not coordinate to Zn2+ and Cd2+, as observed in the acetate salt form of [Zn(2,2′-bipy)3]2+ and in [Cd(2,2′-bipy)3]2+. This last Cd2+ complex did not crystallize, revealing its unfavorable crystallization as an acetate salt form. However, under this last ligand ratio, the persistence of at least one coordinated acetate was observed in the Hg2+ complex with 2 : 1 2,2′-bipy : acetate stoichiometry. Furthermore, there is a cocrystallized 2,2′-bipy in the acetate salt form of [Hg(CH3CO2)(2,2′-bipy)2]+, which is not able to win the competition with acetate for the third coordination site to Hg2+. Even if the 2,2′-bipy amount is 10-times higher than that of acetate in the reaction batch, one acetate remains coordinated to Hg2+. Our crystal form of [Zn(CH3CO2)(2,2′-bipy)2]+ is strongly photoluminescent, with highly efficient emission centered at 356 nm (external and internal quantum yields of 14.2(1)% and 41.3(1)%), whose optical efficiency was rationalized on the basis of time-dependent DFT calculations.Fil: Do Nascimento Neto, José Antônio.

NEOTROPICAL ALIEN MAMMALS: a data set of occurrence and abundance of alien mammals in the Neotropics

Biological invasion is one of the main threats to native biodiversity. For a species to become invasive, it must be voluntarily or involuntarily introduced by humans into a nonnative habitat. Mammals were among first taxa to be introduced worldwide for game, meat, and labor, yet the number of species introduced in the Neotropics remains unknown. In this data set, we make available occurrence and abundance data on mammal species that (1) transposed a geographical barrier and (2) were voluntarily or involuntarily introduced by humans into the Neotropics. Our data set is composed of 73,738 historical and current georeferenced records on alien mammal species of which around 96% correspond to occurrence data on 77 species belonging to eight orders and 26 families. Data cover 26 continental countries in the Neotropics, ranging from Mexico and its frontier regions (southern Florida and coastal-central Florida in the southeast United States) to Argentina, Paraguay, Chile, and Uruguay, and the 13 countries of Caribbean islands. Our data set also includes neotropical species (e.g., Callithrix sp., Myocastor coypus, Nasua nasua) considered alien in particular areas of Neotropics. The most numerous species in terms of records are from Bos sp. (n = 37,782), Sus scrofa (n = 6,730), and Canis familiaris (n = 10,084); 17 species were represented by only one record (e.g., Syncerus caffer, Cervus timorensis, Cervus unicolor, Canis latrans). Primates have the highest number of species in the data set (n = 20 species), partly because of uncertainties regarding taxonomic identification of the genera Callithrix, which includes the species Callithrix aurita, Callithrix flaviceps, Callithrix geoffroyi, Callithrix jacchus, Callithrix kuhlii, Callithrix penicillata, and their hybrids. This unique data set will be a valuable source of information on invasion risk assessments, biodiversity redistribution and conservation-related research. There are no copyright restrictions.
