RESUMO

PURPOSE: The present study aimed to assess whether there was an increase in physical aggression in women treated in Belo Horizonte, Minas Gerais, through the mandatory quarantine. METHODS: Data from a cross-sectional study were collected and analyzed, from March 1 to December 31, 2020. Additionally, data from the same period the previous year were collected for comparison. RESULTS: Of the etiologies reviewed for 2020, physical aggression had the highest percentage increase (+ 4.9%) and was the only etiology that showed a significant difference (p = 0.045). The mean age of the included patients was 34.05 years in 2019 and 33.97 in 2020, and most of the women had facial fractures, with nasal fractures being the most frequent, followed by jaw fractures. There was a significant increase (p = 0.34) in the conservative treatment of fractures from 2019 (48.6%) to 2020 (71.7%) and a minor (p = 0.088) increase in aggression toward intimate partners (2019, 40.9%; 2020, 63.9%). CONCLUSION: Physical aggression against women increased during the period of mandatory social isolation that resulted from the COVID-19 pandemic. Health professionals, including emergency services professionals, must be trained to identify victims and refer them to specialized care.

RESUMO

OBJECTIVE: To describe a cross-sectional study of TMJ dislocation in a Brazilian level-one trauma center. METHODS: The data were collected and analyzed from electronic medical records in a period from 2013 to 2020. RESULTS: Bilateral TMJ dislocation occurred in the majority of cases, being reduced by the Nélaton maneuver associated with Barton's bandage. The average time between the dislocation and specialist appointment was 30.69 hours. Elderly patients were associated with an increased number of recurrent dislocations (p = 0.03). Furthermore, a longer dislocation time was associated with the reduction under intravenous (IV) sedation (p < 0.05). CONCLUSION: The literature is still scarce concerning demographic data, treatment modalities, and follow-up. More studies are necessary to better understand TMJ dislocation management.

RESUMO

An unprecedented study was carried out in a mangrove ecosystem in the northeastern coast of the Brazilian Amazon to understand the behavior of climatic elements in a year with the occurrence of El Niño (2015), associated with the seasonal function source/sink of CO2 by the ecosystem. Global radiation (Rg), net radiation (Rn), temperature, relative humidity, precipitation, horizontal wind speed and direction, as well as turbulent flows of sensible heat (H), latent heat (LE), and carbon (f_CO2) were recorded using eddy covariance, a system for studying turbulent flows of heat and gases in the atmosphere. We observed a drastic reduction in rainfall volumes, which accounts for 63.7% of the expected total according to the region's climatology. Regarding f_ CO2, the highest values of photosynthesis, autotrophic, and heterotrophic respiration of the ecosystem occurred in the wet season due to precipitation, ideal photosynthetically active radiation, lower soil salinity, and higher NDVI of the ecosystem. In the 2nd semester of the year, we observed that the decrease in cloudiness, causing a higher radiation supply in the forest canopy, accompanied by a reduction in precipitation and an increase in the value of H and soil salinity, favored the increase of foliar abscission by the dominant genus Rhizophora and Avicennia, thus influencing the reduction of magnitudes of carbon source/sink functions in the ecosystem during this season, even on high tide days.

RESUMO

The objective of this work was to evaluate the phenotypic divergence among 17 genotypes of sunflower. The experiment was carried out in Papanduva, North Plateau of Santa Catarina State, Brazil, in 2008/2009 cropping season. The experimental design was a randomized block with four replications. The multivariate was used to evaluate the divergence among the genotypes by canonic variable and cluster analysis, based on the generalized Mahalanobis Distance (D2). Univariate and multivariate analyses of variance showed differences among genotypes. The genotypes were grouped in tree clusters. The plant height to the 70 days after the sowing and yield grains showed high contribution towards phenotypic divergence.

O objetivo deste trabalho foi estimar a divergência fenotípica entre 17 genótipos de girassol. O experimento foi conduzido em área experimental localizada no município de Papanduva, SC, na safra 2008/2009. O delineamento experimental utilizado foi de blocos completos casualizados, com quatro repetições. A análise multivariada foi empregada para estimar a divergência fenotípica entre os genótipos, utilizando-se as variáveis canônicas e os métodos de agrupamento de Tocher e UPGMA com base na distância generalizada de Mahalanobis (D2). Análises de variância univariada e multivariada revelaram diferenças entre as cultivares. Os genótipos foram agrupados em três grupos. As características altura de planta aos 70 dias após a semeadura e a produtividade de grãos contribuíram com grande parte da divergência observada.

RESUMO

Since this is an era in which information is open concerning the benefits it brings, the field of nursing informatics earns its moment. The objective of this study was to design educational software for teaching and learning the technique of urinary indwelling catheterization and compare the acquisition of knowledge regarding the technique before and after the implementation of the educational software. This is a descriptive study using a quantitative approach. The pedagogical foundations for designing the software were the theories of Piaget and Vygotsky. The teaching-learning process was evaluated through a questionnaire consisting of 10 multiple choice questions which the 60 participants completed before and after using the software. The results showed the software made significant contributions after its application, thus being very useful in the teaching-learning process.

RESUMO

OBJECTIVES: To assess the results from open or arthroscopic surgical treatment on patients with symptomatic recurrence of rotator cuff injuries. METHODS: Between December 1990 and July 2007, 30 patients were assessed and underwent reoperation performed by the Shoulder and Elbow Surgery Group of the Department of Orthopedics and Traumatology, Fernandinho Simonsen Wing, Santa Casa de São Paulo, because of dehiscence of the rotator cuff suture. The study included patients with symptomatic recurrence of the injury and with at least 24 months of postoperative follow-up. RESULTS: According to the UCLA evaluation criteria, 21 patients (70%) showed excellent or good outcomes; and nine patients (30%) showed fair or poor outcomes. CONCLUSION: Open or arthroscopic surgical treatment of recurrent rotator cuff injuries tended to present worse results than from the primary repair. In this study, we found that 70% of the results were excellent and good. The presence of extensive injuries in the reoperation tended to evolve with larger numbers of unsatisfactory results. In our study, we obtained better results from arthroscopic surgery than from open surgery.

RESUMO

OBJECTIVE: To assess the results from arthroscopic surgical treatment of rotator cuff injuries among patients under 50 years of age. METHODS: Sixty-three patients with rotator cuff injuries who underwent arthroscopic surgical treatment performed by the Shoulder and Elbow Group of the Department of Orthopedics and Traumatology, in the Fernandinho Simonsen wing of Santa Casa Medical School, São Paulo, between August 1998 and December 2007, were reassessed. The study included all patients with rotator cuff injuries who were under 50 years of age and had been followed up postoperatively for at least 24 months. RESULTS: According to the UCLA evaluation criteria, 59 patients (92%) showed excellent and good results; five (8%) showed fair results; and none showed poor results. The postoperative evaluation showed that the mean range of motion was 145° for elevation, 47° for lateral rotation and T10 for medial rotation. Unsatisfactory results were associated with prolonged duration of the injury, with a statistically significant relationship. CONCLUSION: Arthroscopic repair of rotator cuff injuries in young patients produces excellent or good results for most patients.
