RESUMO

Resumen: Introducción: Las fracturas de platillo tibial por mecanismos de alta energía son lesiones graves que ocurren sobre una articulación de carga. Son difíciles de abordar, ya que además de afectar la estructura ósea de la pierna suelen tener lesiones de partes blandas asociadas. Objetivo: Evaluar los resultados radiológicos y funcionales de las fracturas de platillo tibial de alta energía con un mínimo seguimiento de un año. Material y métodos: Estudio retrospectivo, observacional y multicéntrico. Análisis de los resultados radiológicos y funcionales en el tratamiento de fracturas de platillo tibial de alta energía tratadas mediante reducción abierta y fijación interna (RAFI) entre 2014 y 2019. Resultados: 54 fracturas tratadas mediante RAFI. Seguimiento un año, 98.1% de consolidación en 13 semanas de promedio, 83.4% sin alteraciones del eje en plano coronal, 74% sin ensanchamiento articular postoperatorio. Escalas funcionales: Lysholm 82.1 puntos promedio y Oxford Knee Score (OKS) 39.5 puntos promedio. Conclusión: El rango de movilidad articular se redujo luego de una fractura de platillos tibiales de alta energía, pero con buenos resultados funcionales. Cuanto menor deseje y menor ensanchamiento radiográfico postoperatorio, se obtienen mejores resultados.


Abstract: Introduction: The tibial plateau fractures due to high-energy mechanisms are serious injuries that occur on a load bearing joint. These are difficult to approach because, also affect the bone structure of the leg, they usually have associated soft tissue injuries. Objective: To evaluate the radiological and functional results of high-energy tibial plateau fractures with a minimum follow-up of one year. Material and methods: Retrospective, observational and multicenter study. Analysis of radiological and functional outcomes in the treatment of high-energy tibial plateau fractures, treated by open reduction and internal fixation (ORIF) between 2014 and 2019. Results: 54 fractures treated by ORIF. Follow-up one year. 98.1% consolidation in 13 weeks on average. 83.4% without alterations of the axis in the coronal plane. 74% without postoperative joint widening. Functional scores: Lysholm 82.1 average points and Oxford Knee Score (OKS) 39.5 average points. Conclusion: The joint range of motion was reduced after a high-energy tibial plateau fracture, but with good functional results. The less off axis and less post-operative radiographic widening, the better results are obtained.

RESUMO

UNLABELLED: This study aimed to assess the genetic diversity of fish isolates of Streptococcus agalactiae by capsular serotyping, MLST and the pattern of selected virulence genes. Forty-six isolates from Nile tilapia and Amazon catfish were screened by PCR for the twelve virulence genes. The molecular capsular type and sequence type (ST) were determined. Two capsular types (Ia and Ib) and four STs (103, 260, 552 and 553) were identified. The ST-552 and ST-553 represent new allelic combinations. Variable results were found for the genes gbs2018-6, lmb, hylB and cylE. The combined evaluation of serotype, sequence type and pattern of the presence or absence of cylE and hylB allowed the classification of isolates into nine genetic profiles (I-IX). The proposed scheme showed higher discriminatory power and was able to detect evolutionary events missed by MLST analysis. This study provides new information about the genetic diversity of fish pathogenic Strep. agalactiae, and the proposed scheme was shown to be an improved approach to genotyping these strains. SIGNIFICANCE AND IMPACT OF THE STUDY: This study showed that critical genetic events in Streptococcus agalactiae isolates pathogenic for fish have been missed by serotyping and multilocus sequence typing (MLST). A proposed genotyping scheme based on the evaluation of concatenated data from serotyping, MLST, and the presence/absence of virulence genes was created, and this was able to detect old and recent evolutionary events. It provided a better understanding of the genetic diversity of Strep. agalactiae populations from fish and will contribute to future studies of the molecular epidemiology, pathogenesis and evolutionary aspects of this pathogen.

RESUMO

Exercise increases the expression of brain-derived neurotrophic factor (BDNF) in rodents and in healthy humans. Its relationship with weight loss and improvement in metabolic parameters, in obese human subjects, has not been elucidated. The aim of the study was to evaluate the effect of an aerobic exercise program on circulating levels of BDNF in overweight and obese subjects. We measured anthropometric and metabolic parameters in 15 male and female nondiabetic outpatients (age 38.3±9.5 years, BMI 27-35 kg/m2), before and after 30 sessions of aerobic exercise (3 sessions per week). Plasma (p), serum (s), and platelet (plat) BDNF concentrations were measured at basal condition and after completing 15 and 30 sessions of exercise. Subjects were advised to continue their usual food intake. A significant decrease in weight, BMI, waist circumference, diastolic blood pressure and total cholesterol was observed at the end of the study (p<0.02). Serum and platBDNF showed a significant increase during the training period (p=0.005 and 0.04 respectively). However, pBDNF showed no significant increase. Area under the curve of glucose at baseline, was inversely correlated with sBDNF (r= - 0.53, p=0.04) and platBDNF (r= - 0.6, p=0.01) after session 15. Also, platBDNF was correlated inversely with post load insulin and HOMA2-IR at the end of the training program (r= - 0.53, p=0.03 and r= - 0.52, p=0.04, respectively). In overweight and obese subjects, serum and platBDNF levels increase after 30 sessions of aerobic exercise. This is accompanied with the improvement of anthropometric and metabolic parameters and modest weight loss.

RESUMO

Streptococcus agalactiae is an emerging pathogen in Nile tilapia (Oreochromis niloticus) worldwide. To investigate aspects of the epidemiology, transmission and virulence of S. agalactiae infections, nine outbreaks of meningoencephalitis and septicemia in Nile tilapia farms in Brazil were analyzed. Records from the outbreaks revealed large variation in the weight of fish affected, high mortality, and disease occurrence at water temperatures above 26 degrees C. S. agalactiae was isolated from diseased fish from all farms, and 29 strains were identified by phenotypic tests and 16S rRNA gene sequencing. Five strains from different geographic origins were selected to determine the 50% lethal dose (LD(50)). All strains were highly virulent; for example, strain SA 20-06 had an LD(50) of 90 bacteria. To investigate S. agalactiae transmission, we conducted cohabitation assays with diseased and healthy fish and fish challenges using an immersion bath or gill inoculation. Strain SA 20-06 was used in all assays. The disease was reproduced with characteristic clinical signs and S. agalactiae was reisolated in all trials. The infection route studies were identified as by direct contact or through the water. In conclusion, S. agalactiae, a major pathogen of Nile tilapia in Brazil, exhibited high virulence, regardless of the geographic origin of the isolated strains.

RESUMO

OBJECTIVE: Systemic inflammatory response syndrome (SIRS) without infection is a well known phenomenon that accompanies various acute cerebral insults. We in tented to determine whether SIRS was associated with outcome in patients with spontaneous intracerebral hemorrhage. PATIENTS AND METHODS: In patients with intracerebral hemorrhage, the occurrence of SIRS was assessed according to the guidelines of the 1992 Consensus Conference. SIRS criteria and other prognostic parameters were evaluated as predictors of final outcome. RESULTS: SIRS was highly related to poor clinical grade (Glasgow coma scale), hemorrhage volume on CT scan and intraventricular extension of hemorrhage. By univariate analysis,the occurrence of SIRS was associated with higher mortality and morbidity rates than was the nonoccurrence (p<0.005). CONCLUSIONS: In patients with intracerebral hemorrhage, SIRS reflected the extent of tissue damage and predicted a poor outcome.

RESUMO

La trombosis venosa cerebral es menos frecuente que la arterial como causa de stroke, sin embargo aún continua subdiagnosticada. Fisiopatológicamente se caracteriza por un desequilibrio entre factores trombogénicos y fibrinolíticos. Los desórdenes hematológicos tienen un rol protagónico importante, destacándose entre ellos el sindrome antifosfolipídico, el cual debe particularmente sospecharse cuando el accidente cerebrovascular ocurre en individuos jóvenes

RESUMO

A 38 year-old woman had an anterolateral wall myocardial infarction and acute left ventricular failure 11 days after a cesarean section. Coronary angiography performed 14 days later because of recurrent angina disclosed dissection of the left main coronary artery. She subsequently underwent aorto coronary bypass surgery uneventfully. Spontaneous coronary artery dissection is a rare entity that mainly affects women in peripartum periods and presents a high mortality rate.

RESUMO

We reviewed the clinical data on 23 patients operated on for constrictive pericarditis. Mean age was 35 years and 17 were males. The chief complaint was dyspnea (87%). Outstanding physical findings were venous hypertension (96%), hepatomegaly (78%), ascitis (57%), pulsus paradoxus (57%) and Kussmaul sign (43%). The ECG, although always abnormal was non contributory. Chest X ray findings included cardiomegaly (48%) and pericardial calcification (35%). Half of the cases showed pericardial thickening and abnormal septal motion on M mode echocardiography. An equalization of diastolic pressures and the dip and plateau sign was confirmed at cardiac catheterization in all cases. The etiology could be established in only 6 patients (tuberculosis 3, traumatic 2 and septic 1). Surgical mortality was 9% (2 patients). Follow up was available on 10 patients at a mean of 35 months, 9 in functional class I and 1 in FC II.
