RESUMO
PURPOSE: The objective of this study is to perform a meta-analysis comparing the effectiveness of uterine artery embolization (UAE) versus peripartum hysterectomy for acute refractory postpartum hemorrhage (PPH) control. MATERIALS AND METHODS: We systematically searched 6 medical databases for studies comparing UAE and hysterectomy in PPH. Outcomes examined were mortality, hospitalization duration (HD) in days, and red blood cells (RBC) units utilization. Statistical analysis used RevMan 5.1.7 and random-effects models. Odds ratios (OR) and mean differences (MDs) with 95% confidence intervals (CIs) were used for dichotomous and continuous outcomes, respectively. RESULTS: We included 833 patients from 4 cohort studies, with 583 (70%) undergoing UAE. The UAE population required fewer RBC units (MD: -7.39; 95% CI: -14.73 to -0.04; p=0.05) and had shorter HD (MD: -3.22; 95% CI: -5.42 to -1.02; p=0.004). Lower mortality rates were noted for UAE in the pooled analysis, but no statistical significance. Uterine artery embolization demonstrated lower procedural complications (16.45% vs. 28.8%), in which UAE had less ureter and bladder lesions (OR: 0.05; 95% CI: 0.01-0.38; p=0.004 and OR: 0.02; 95% CI: 0.00-0.15; p<0.001, respectively). Only 35 (6%) required conversion to hysterectomy, while 27 (4.6%) underwent re-embolization with 100% bleeding control. Uterine artery embolization did not hinder fertility, with normal menstruation restored in 19 patients with postoligomenorrhea. CONCLUSION: Uterine artery embolization for the control of PPH is associated with lower use of RBC units and HD, but similar rates of mortality are noted when compared to hysterectomy. These results associated with uterine preservation could support its importance for refractory PPH management. CLINICAL IMPACT: Uterine Artery Embolization is associated with a shorter hospitalization duration and reduced use of red blood cell units when compared with hysterectomy in refractory postpartum hemorrhage. Although demonstrating similar mortality rates, these findings, together with fertility preservation, support the method incorporation as a valuable option in obstetric services.
RESUMO
Caesalpinioideae is the second largest subfamily of legumes (Leguminosae) with ca. 4680 species and 163 genera. It is an ecologically and economically important group formed of mostly woody perennials that range from large canopy emergent trees to functionally herbaceous geoxyles, lianas and shrubs, and which has a global distribution, occurring on every continent except Antarctica. Following the recent re-circumscription of 15 Caesalpinioideae genera as presented in Advances in Legume Systematics 14, Part 1, and using as a basis a phylogenomic analysis of 997 nuclear gene sequences for 420 species and all but five of the genera currently recognised in the subfamily, we present a new higher-level classification for the subfamily. The new classification of Caesalpinioideae comprises eleven tribes, all of which are either new, reinstated or re-circumscribed at this rank: Caesalpinieae Rchb. (27 genera / ca. 223 species), Campsiandreae LPWG (2 / 5-22), Cassieae Bronn (7 / 695), Ceratonieae Rchb. (4 / 6), Dimorphandreae Benth. (4 / 35), Erythrophleeae LPWG (2 /13), Gleditsieae Nakai (3 / 20), Mimoseae Bronn (100 / ca. 3510), Pterogyneae LPWG (1 / 1), Schizolobieae Nakai (8 / 42-43), Sclerolobieae Benth. & Hook. f. (5 / ca. 113). Although many of these lineages have been recognised and named in the past, either as tribes or informal generic groups, their circumscriptions have varied widely and changed over the past decades, such that all the tribes described here differ in generic membership from those previously recognised. Importantly, the approximately 3500 species and 100 genera of the former subfamily Mimosoideae are now placed in the reinstated, but newly circumscribed, tribe Mimoseae. Because of the large size and ecological importance of the tribe, we also provide a clade-based classification system for Mimoseae that includes 17 named lower-level clades. Fourteen of the 100 Mimoseae genera remain unplaced in these lower-level clades: eight are resolved in two grades and six are phylogenetically isolated monogeneric lineages. In addition to the new classification, we provide a key to genera, morphological descriptions and notes for all 163 genera, all tribes, and all named clades. The diversity of growth forms, foliage, flowers and fruits are illustrated for all genera, and for each genus we also provide a distribution map, based on quality-controlled herbarium specimen localities. A glossary for specialised terms used in legume morphology is provided. This new phylogenetically based classification of Caesalpinioideae provides a solid system for communication and a framework for downstream analyses of biogeography, trait evolution and diversification, as well as for taxonomic revision of still understudied genera.
RESUMO
Resumo: Introdução: O conhecimento sobre pesquisa científica e a compreensão dela são habilidades que devem ser desenvolvidas por todos os profissionais de saúde. Especificamente na Medicina, essas habilidades compõem uma parcela importante da graduação e da educação médica continuada. Considerando que a formação médica possui estreita relação com a compreensão sobre evidências científicas, torna-se relevante analisar o envolvimento dos estudantes de Medicina com as atividades científicas durante o curso. Objetivo: Este estudo teve como objetivos verificar o interesse e o envolvimento em pesquisas científicas entre os estudantes de Medicina por meio da análise do perfil acadêmico e das atividades extracurriculares realizadas, avaliar a produção científica e identificar as motivações e dificuldades enfrentadas. Método: Trata-se de um estudo transversal, realizado com estudantes de Medicina de Salvador, na Bahia, maiores de 18 anos. Aplicou-se, por meio do Microsoft Forms, um questionário virtual, estruturado e anônimo contendo 21 perguntas acerca do perfil acadêmico e das atividades extracurriculares realizadas, além de dados sobre a produção científica e as motivações e dificuldades enfrentadas pelos estudantes. Resultado: Dos 460 estudantes participantes, houve predominância de mulheres (63,3%), com idade de 24,1+6,1 anos, cursando os ciclos básico (45,4%) e clínico (46,7%), que não possuem desejo prévio de trabalhar com pesquisa (54,8%). Dentre os participantes, 54,6% integraram ligas acadêmicas, 31,1% possuem envolvimento com grupos de pesquisa e 29,1% participaram de monitoria. Verificou-se que apenas 33,9% dos estudantes possuem resumos publicados em congressos, 12,2% são coautores de artigos científicos e 7,4% são autores principais. O interesse em trabalhar com pesquisa aumenta durante a graduação (p = 0,010), estando os estudantes motivados para produzir cientificamente (66,1%). A experiência em pesquisa (27,4%) e o interesse genuíno na descoberta científica (20,9%) foram os principais fatores motivadores. Entretanto, 81,1% dos discentes identificaram dificuldades para produzir conteúdo científico e apontaram como empecilhos a orientação inadequada (16,0%) e a falta de tempo (15,5%). Não foi observada relação entre a motivação e a dificuldade para produzir cientificamente e o ciclo acadêmico em curso. Conclusão: Os estudantes de Medicina demonstram interesse e participação em pesquisa científica, entretanto aqueles que, de fato, estão envolvidos com atividades científicas representam a minoria.
Abstract: Introduction: Knowledge and understanding of scientific research are skills that must be developed by all health professionals. Specifically in Medicine, these skills make up an important part of undergraduate and continuing medical education. Considering that medical training is closely related to the understanding of scientific evidence, it becomes relevant to analyze the involvement of medical students with scientific activities during the course. Objective: This study aimed to investigate the interest and involvement in scientific research among medical students, analyzing the academic profile and the extracurricular activities carried out, in addition to evaluating the scientific production and identifying the motivations and difficulties faced. Method: A cross-sectional study carried out with medical students from Salvador/Bahia, over 18 years of age. A virtual, structured, anonymous questionnaire was applied through Microsoft Forms, containing 21 questions about the academic profile and extracurricular activities carried out, in addition to data on scientific production and the motivations and difficulties faced by students. Result: Of the 460 participating students, there was a predominance of women (63.3%), aged 24.1+6.1 years, attending the basic (45.4%) and clinical (46.7%) cycles, who have no previous desire to work with research (54.8%). Among the participants, 54.6% were part of academic leagues, 31.1% were involved in research groups and 29.1% participated in monitoring. It was found that only 33.9% of students have abstracts published in congresses, 12.2% are co-authors of scientific articles and 7.4% are main authors. Interest in working with research increases during graduation (p = 0.010), with students motivated to produce scientifically (66.1%). Research experience (27.4%) and genuine interest in scientific discovery (20.9%) were the main motivating factors. However, 81.1% of students identify difficulties in producing scientific content, with inadequate guidance (16.0%) and lack of time (15.5%) being the main obstacles. No relationship was observed between motivation and difficulty to produce scientifically and the current academic cycle. Conclusion: Medical students show interest and participation in scientific research, however those who are actually involved in scientific activities represent the minority.
